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.
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.
