Hello Overclock forums. This is my first post.
I just bought new pc with screen (build my self)
I7 4790K
16gb ddr3 2400
ssd 850 240gb
asus strix oc rx480 8gb
asus MG248Q monitor

I have noticed some strange lines that go from down to op across the whole screen, they are not that prononced but very notisable when you know they are there. Here comes my findings. When disableing Freesync on monitor the montor reboots and lines gone. When freesync on and i reboot monitor the lines go away, but come back after 10-30 minutes. freesync off/on in crimson does nothing for this problem. When going to 120hz the lines disapear. Its like lines thats lighter then the color on display going horizontal from and they go from down to up it looks like. they are at the whole width of the screen. It seems to be a freesync 144hz problem. but i bought this system to be able to use freesync and 144hz in games. I have uploaded a video and picture please watch it . What should i do ? RMA my monitor ? will a new one be better or should i get another model ? i believe the problem is with the monitor not the computer /gfx , as reboot monitor causes the problem to disappear.
Thanks in advance!

Youtube link for video of the problem =

Yeah, have something similar with the ASUS PG248Q and even the AOC G2460PG. It gets worse from 144Hz and higher. At 120Hz, it's fine, but these are 120Hz panels (natively). The 144Hz is actually an overclock.

So, it's the panel and unfortunately, this is normal for this exact panel.

So there is nothing i can do about it ? Except for change for another montor? Which would you choose. I need freesync 144hz, low ms , 24 inch. Should i keep it and run it at 120hz , or should i get something else? All advise and informations are appriciated.
Thank you for your reply.

To be honest, I would keep it at 120Hz if it bothers you enough because right now, finding a good 1080p gaming monitor to match or beat the ASUS MG248Q could prove to be quite frustrating. You could end up playing the Panel Lottery for several weeks or months before you get one that doesn't have some sort of problem. I've been at this since the beginning of August and I'm still looking for a 24" 1080p high refresh rate low response time G-SYNC monitor that doesn't have some sort of stupid problem, whether it's a defect or just the way the panel is. It's extremely frustrating. I'm on my 3rd monitor!

I had the Acer XB241H, but that one had extremely bad backlight uniformity: when looking at a very dark game scene, it became apparent that the entire bottom-half had a "clouding" thing happening. It wasn't gamma shift either. The XB241H also had a very annoying design characteristic: the OSD indicator that says which signal type I'm using was big and located right in the center of the screen, and it would come up every single time I started Windows, logged out and logged back in, restarted Windows, and every time I'd change the refresh rate or the resolution or if the refresh rate or resolution were changed automatically by a video game being launched. So, sometimes Alt+Tabbing out and back in a game would cause it to come up. That alone was worth returning the monitor.

Then I tried the ASUS PG248Q, except it has the problem that you're describing. Other than that, it's a great monitor.

Now I'm trying the AOC G2460PG, but it has the same problem. Sigh. lol To add insult to injury, it's the only thing I don't like about the G2460PG. If it didn't have this problem, then I'd be cheerfully yelling "it's a keeper!!!" I'm afraid to return it though because I don't know what other monitor to try. So I don't know what to do.

I don't know if you'd experience the same thing with Freesync monitors, but my experience so far has shown me that finding a good 24" 1080p gaming monitor can be quite difficult.

Thank you for that great reply. I have also looked at the AOC G2460PF , but it is the same as the AOC G2460PG just with freesync instead of gsync (im using amd graphics card with freesync and need that type of monitor) , i also believe that the ASUS MG248Q which i have is the same as the PG248Q that you have , again just with gsync instead of freesync. It seems that there are no other options. It is a shame, cause i like the montior alot , i actually find the viewing angles good, colours good, and design and so on are spot on. It is wierd, today i have not seen the problem , even tough i run 144hz@freesync active. I was just thinking if there were any other monitors i could choose from, but there are not many. i have the following criteries. 24 inch, fullhd/2k , 144hz, 1ms, amd freesync/vesa adaptive sync. and hopefully an affordable price. i paid 362 USD for the MG248Q. Prices are not that cheap here in the north. The aoc however is cheaper its only 295usd..

I've tried two XL2430s and a 24GM77. All had the horizontal "scanlines" issue at 120hz and more pronounced at 144hz. Every second row of pixels was slightly brighter. Most pronounced at the left side of the screen. On the LG, it was the worst -- entire left side of the screen was covered with them and they extended up to the middle. Most visible on grey and pastel colors. Not visible on black.

On the BenQs, they would move upwards, causing a sort of flickering sensation. They did the same on the LG unless "DAS" mode was on which would just make them stand still. Sounds like it's less annoying that way, but not really. BenQ's equivalent "Instant Mode" did nothing to change their behavior though.

It seems like it's impossible to find a 1080p 144hz TN without this issue. I think the newer batches seem to be faulty because if this were always the case, you'd hear about it more often. Also, I would expect this issue to be sorted out on the new panels like the MG248, but clearly that's not the case.

I've been slaving away for two months trying to find a monitor without this issue. I've returned the 24GM77 yesterday, now it's going through the warranty process and I'm waiting for a replacement. There will be hell to pay if they pretend not to notice this issue - or worse yet, if they try to convince me it's not a big deal. The coating on these monitors is so harsh that they look dirty out of the box and with scanlines thrown into the mix, the visibility is even worse. After two months of dealing with this and hauling boxes all over town, I feel lobotomized and I just want this over with.

It's going to be very hard to find a good one. Even if you score one without this issue, you could run into other deal breakers like horrid uniformity and backlight bleeding, dead pixels, overly pronounced pixel inversion, dead rodents stuck in the chassis, anthrax, curses that will wipe out your entire bloodline and other wonderful surprises. However, you should absolutely not put up with this crap. Either keep returning until you get a good one or ask for your money back, but definitely don't send a signal to manufacturers that this is acceptable for a product that passes QA.

And don't for a moment think along the lines of "well, these are cheap monitors, I got what I paid for". Nah. The M24HW01V8 was considered premium stuff for quite a while and suddenly we're supposed to consider it a cheap product? There's no reason to believe your M240Q007 should be any worse either - hell, it's a new panel. And really, if this kind of thinking made any sense, the expensive gaming 1440p IPS panels wouldn't suffer the same horrid QA these "cheap" monitors do.

The "moving scanlines" thing is bizarre. That was never reported back when the Asus VG248QE was popular (the STATIC, not moving scanlines , were reported, usually in lightboost mode, and if you were unlucky, at 144hz and faintly at 120hz), and the only time this was reported on Benq monitors, was when the wrong vertical total (VT) was being used on Z series monitors for blur reduction. Changing the VT value would stop the scanlines from moving, but wouldn't remove them from the screen.

You're saying on your XL2430T, (and on the LG), the scanlines moved without a VT tweak even active?

I can't even disable instant mode on the XL2720Z at 144hz. The screen starts lagging EXTREMELY bad like it was being overclocked too far.
I can at 120hz (WITHOUT a VT tweak). There are no scanlines at 120hz without a VT tweak, and so faint they may as well be invisible at 144hz.
*edit* I don't see any scanlines at 144hz.

Yep! You and I are going through the same thing.

I started out with an Acer XB241H purchased from B&H last month at around August 9th. It didn't have any scanlines or any other problems like that, but instead it had horrible backlight clouding on the bottom-half of the panel. It was so bad that I couldn't even play certain games that often put me in dark spaces like Descent 2 without being extremely irritated with that distraction. Once I noticed it, it was impossible to unsee.

So, I returned it as "defective" and I got my full refund and B&H even paid for the return shipping! I think that was an older panel because I would imagine most people just get their monitors from Amazon.com or Newegg.

Anyway, so I replaced it with an ASUS PG248Q directly from Best Buy because I wasn't going to screw around with return shipping again. Well, to me it's obvious I had the newer panel because it had those damn scanlines and the grid-like pattern that was visible on top of it, especially in darker rooms in games. At 120Hz, the panel was perfect. This monitor has another problem though that made it impossible for me to live with: anytime the resolution or the refresh rate gets changed - whether I do it or whether a game does it, there's a chance for the monitor to lose its signal and this locks the entire computer up. I figured that out when I couldn't blindly shut down or restart. So, I returned that piece of crap. Yep, I'm calling the ASUS ROG Swift PG248Q a piece of crap. I wouldn't take that monitor, even if it were free. Why? Because I'd never use it.

Returning the monitor to Best Best buy was amusing. The guy working at the Customer Service desk was obviously a PC gamer in his very early 20s. As soon as he saw what I was holding, he looked at me and in a very friendly tone was like, "You're returning the ASUS PG248Q?!?!?!" lol Yep! It's garbage, man. Let me explain it to you! hahahaha Of course, he didn't understand and thought that maybe it was either PEBKAC or maybe my computer. lol Sigh.

Currently, I am using the AOC G2460PG and surprise surprise, it's the same panel as the PG248Q I had. Except, I can't get this thing to lose its signal no matter how hard I try. So I'm happy with that. I also can't overclock it, so the issue this panel has with these damn scanlines (if that's what they are) and the grid pattern can't be made worse. So, I don't know... I might keep this one. Sigh. I have until October 7th to make a final decision. It really pisses me off because this is a ~$400 monitor. Yes, it's really more like a ~$300 monitor because the G-SYNC module adds a good $100 or so, BUT STILL. When I bought my 8½-year old Samsung 2253BW, it was a simple process: ask Overclock.net what the best monitor under $400 is, get recommended the 2253BW, buy it, and be done. Today? LOL YEAH GOOD LUCK!!!

I'll be back later. I need to go destroy several large buildings with my bare hands now. I wish I could freely use profanity right now because goddamn. I just want to drop like a thousand F-bombs at the moment.

Yes, they move. The movement itself is kind of strange and difficult to describe. It's as if the lines are static but moving upwards at the same time. I don't have the monitor handy to examine it closely right now, but I think I know what leaves this impression of movement. Instead of being uniformly bright, one of the lines is a bit brighter, and that brightness migrates to the next upwards "scanline" row at every refresh. It's not just one row of brighter lines either, there's many of them distributed along the screen and they move upwards in tandem. So the position of the "scanline" grid itself is never actually moving, but it's "animated". I hope this makes sense because it's really difficult to put into words.

I think you nailed it. It gives the illusion of moving lines.

Luckily, I didn't have this issue with the two stores I went through. The first store was incredibly professional in that they actually let me try the XL2430 I returned side by side with another candidate right there in the store itself so I could do all testing I wanted to do without having to carry the box home. Never a snide look or rushing me along. Better yet, not pretending to understand what I'm testing for but also not assuming I'm some sort of freak who gets off on returning hardware for no reason. Just letting me do my thing. Unfortunately, the replacement candidate had the scanline issue as well. I could have asked for a third one (they had five in total), but at that point I really just wanted to move on to the 24GM77 because in time, I realized it is a better and cheaper choice for my purposes. So instead of pestering them further, I called it quits on the BenQ. Too bad because I really wanted to give those guys my money.

So I took my money back and moved on to the other store that had the 24GM77, but unfortunately, there was no way to test several units in this fashion. This is the second time I'm returning the 24GM77 and they're still very cordial. I very much appreciate the lack of insinuation that I'm a pedantic ******* who has nothing better to do than to pester them. I'd definitely snap then and there if one of these retailers tried to pull that crap on me. It's bad enough doing something crazy without being called crazy. And crazy it is, kind of. Waging an impossible uphill battle against abysmal QA, and for what? Video games. Gaming is supposed to be fun, not a RMA gauntlet without any actual gameplay involved.

It's kind of funny because I don't even play video games that much. Throughout all this, I'm kind of puzzled as to why I'm putting so much effort into this.

Oh don't get me wrong, he was friendly and cool about it. With the way he handled me, I felt like he and I had been friends for a long time. I totally understood why he was surprised by someone actually returning that monitor because in the PC gaming community, that monitor is supposed to be extremely high-end and highly coveted by others who can't afford it. He wanted so badly for me to keep it because of how awesome he thinks it is (he wanted nothing but the best for me), so he wanted to dig a little just in case it might be either something wrong with my computer or maybe something I was doing that I needed to change. I mean, he really cared and he really wanted to see me walk back out with it very happy that I can keep it and can stop having to deal with it by making some change to either what I'm doing or what my computer is like. He just felt so bad that I couldn't keep it because of that problem that he wanted to do what he could to see if I could keep it, but he quickly understood that it is indeed the monitor itself.

It's a difficult thing to explain to someone too, especially when the majority of this planet's population wouldn't even really notice it or care. Even the employee I bought the monitor from said that these lines and whatnot wouldn't bother him - and that's perfectly valid to me. If this is something that wouldn't bother someone, then I'd probably recommend the monitor - as long as they can put up with a risk of losing the monitor's signal connection and being forced to do a cold reboot if it happens.

At the moment though, the AOC G2460PG that I have is making me happier than the XB241H and PG248Q did. It has the exact same panel as the PG248Q but with slightly inferior gamma handling. During the first day of use, I'd often be thinking that its brightness is inferior or something, but I learned that it's just an inferior gamma handling. I'm assuming that AOC didn't really tune it very well or didn't spend enough time tuning it. I don't know, but I'm almost at the point where I just can't care anymore because it seems my only option is to exchange the G2460PG for another with the risk of ending up with the older panel that has no scanlines but instead has horrible backlight uniformity - that is, if that problem plagued the G2460PG when it had the older panel. Or worse, ending up with one that has bad backlight uniformity with scanlines as well. Right now, the AOC G2460PG I have has a backlight uniformity that I can live with, and those scanlines and grid-pattern artifacts could be a lot worse, so I guess I might be keeping this thing. I don't really know yet. Sigh.

Because at the desktop, the high refresh rate is fantastic and you don't have to deal with IPS glow. If you get one that has an adaptive sync technology that your video card can use (like how I want G-SYNC0, then you'll also have the peace of mind that anytime you play a game, you'll have that as well.

You know, it's possible that he's just doing his job. It's his job to make sure that the customer leaves money and that they are happy about leaving that money. But I don't know. I don't mean to ruin what could have been a honest bro moment on his part. Bottomline, it's irrelevant either way. What matters is that he wasn't questioning your legitimacy as an informed customer. Even if he questioned if the problem is in your PC or the cables you used, it's actually good practice to put this out there as a possibility because most customers actually are clueless. I bet there's at least one guy returning a monitor every month because he couldn't get 144hz over HDMI in Call of Battlestrike or he tried to plug the power cord into his ass and now he complains that it hurts too much and that ASUS didn't include lube.

Perhaps there's an acceptable amount of this "scanline" crap that's possible to live with. I guess I could say "you have to figure out if it's really bothering you or if you're being picky", but what's so picky about "hey, I wanted a high refresh rate panel for clarity of motion, but there's these horizontal lines in the way making it difficult to see things". Man, it's possible to get over some uniformity issues and even a few dead pixels if they're in the corners and out of the way. But if there is a defect that's actively interfering with the whole purpose of the device, that's kind of a big deal. The only reason you're having an internal debate over whether to keep it is because you're tired of returning monitors and doubting whether you'll even find a good one. That's not being picky, that's being a victim of unprofessional manufacturers.

If you have the cash, I suggest waiting for 240hz panels. Give up the search, take your money back and wait for that next generation. They are right around the corner. At the very least, they shouldn't have scanlines at 200hz. One can hope. The only reason I'm not doing this is because I don't want to spend that much on gaming.

Yeah, it's kind of cool watching that cursor fly around, but I honestly don't care about anything above 60hz in desktop. I'm buying this thing for Overwatch and later on Diabotical. Maybe Quake Champions turns out alright as well. I want to have one of these monitors lying around for when I'm playing these fast arena shooters because I think they're really just unplayable on a 60hz LCD. I got into Quake as a kid and I never really outgrown it.

And I never had to worry about IPS glow because my general purpose monitor is a VA.

The moving scanlines thing only happened on the XL2411Z if the vertical total were set to a value the monitor didn't like, in VT 1497-VT 1502 range.
Otherwise our scanlines were stationary and non moving (static).

I have scanlines right now on XL2720Z at 100hz, vertical total VT 1500. No scanlines at VT 1133 (default)
But they're not moving.
Scanlines at 120hz VT 1500 Not moving. None at VT 1144.
No scanlines at 144 hz.
Lots of scanlines in Lightboost mode. Not moving though.

My Asus VG248QE also had scanlines at 144hz (annoying) and 120hz. But not moving.

Moving scanlines though.....what did AUO do to these panels?

I have scanlines right now on XL2720Z at 100hz, vertical total VT 1500. No scanlines at VT 1133 (default)
But they're not moving.
Scanlines at 120hz VT 1500 Not moving. None at VT 1144.
No scanlines at 144 hz.
Lots of scanlines in Lightboost mode. Not moving though.

My Asus VG248QE also had scanlines at 144hz (annoying) and 120hz. But not moving.

Moving scanlines though.....what did AUO do to these panels?

No idea. I'm also wondering why LG's DAS makes them stop moving.

I can't even test instant mode cuz there's no difference on/off at stock 120hz since I don't have scanlines there too.
And I can't turn off instant mode with VT 1500 tweak active at 120hz. The screen starts breaking up into triangles and jittering like crazy.
144hz->turn off instant mode-->Screen feels like a VERY LAGGY 60hz monitor running at an overclock it cant handle.

But turning off instant mode at 100hz with VT 1500 works. The scanlines vanish, but so does the effect of the VT tweak too...strobe crosstalk becomes like there's no VT tweak active.

Instead of being uniformly bright, one of the lines is a bit brighter, and that brightness migrates to the next upwards "scanline" row at every refresh. It's not just one row of brighter lines either, there's many of them distributed along the screen and they move upwards in tandem. So the position of the "scanline" grid itself is never actually moving, but it's "animated". I hope this makes sense because it's really difficult to put into words.

I have exactly the same issue with AOC G2460PG. I think all these monitors use the same panel from AU Optronics. BUT those scan lines are not there all the time and I have no idea what's the pattern of their occurrence. What I know for sure that they are there in ULMB at 120Hz all the time and disappear on 100Hz. With G-sync they are never present at 120Hz but occasionally I can see them at 144Hz. After some tries with resolution changes or toggling g-sync they disappear but may appear after some time. Usually if I turn computer off during night and the next day they are there. Really strange behavior indeed. Anyone have an idea what this could be ? It's from overclocking ? I don't think it's a g-sync because in ULMB it's present as well at 120 Hz. With G-sync sometimes it is there, sometimes not. Looks like some driver issue or what.
