Brightness: 17
Contrast: 50
Gamma: 2.2
Color Temp: User
R: 45
G: 44
B: 51
Everything else is default, and i have left the monitor at 144hz as overclocking the panel greatly reduces contrast and kills the image quality more than it already is for being a TN.

That said here are some screenshots of my calibration results: Warning: Spoiler! (Click to show)

Ignore the grey line, thats the gamma curve for BT.1886 and i did a power law gamma 2.2 calibration


Here is my icc profile for anyone that wants to try my settings: XB241H12016-06-1623-262.2SXYZLUTMTX144hz.zip 688k .zip file

 

Where did you go to change the RGB values? Did you go into the 6-axis color section and only change RGB while leaving the other 3 colors at 127?

Just picked this monitor up so far so good !
post #95 of 321
Has anyone done proper testing on this monitor? I would like to know the Input lag at 144hz and the input lag at 60hz.
post #96 of 321

I wouldn't get this monitor again even if someone paid me. Please allow me to explain.

 

First, the uniformity of its brightness sucks and it affects everything, especially because I can't unsee it! You can't really see it very easily unless you're looking at an image that's very dark like some games and movies are (you can really see it if you just test it with the Blank screensaver). I know you'd want photos and I could try to borrow my mom's camera to take some, but it's super expensive and she strongly prefers that I don't touch it (and I don't really know how to use it anyway), so I'll try to explain it instead:

 

There's a distinct area that's brighter, and it begins sharply at about 1/3 the way down from the top (slightly further down than 1/3 the way actually - almost half the way down), and it pretty much fills most of the bottom half of the panel, but definitely not all of it - and also not evenly at all. So, the top 1/3 or top half (mostly) is distinctly darker and there's a relatively sharp line where the darker area begins - or where the brighter area begins, or where it ends. It's sorta like I'm looking at an outdoor photo with a very dark sky that has nothing in it and a slightly milky foreground of some kind. Also, the center of the panel is brighter than the rest, about 3-4 inches in a slightly oval shape.

 

Again, you can't really see any of this unless the entire panel is displaying something very dark. Even displaying nothing but white reveals this problem, but it requires a different way to explain it that I can't figure out. Regardless, I'm sick and tired of this monitor and I'm returning it even though it would cost me ~$40 to ship it back.

 

As you can imagine, this can be very distracting. The darkest-looking video game I have is Descent 1 and 2, and so this is especially noticeable and extremely distracting in the darkest parts of the maps where the panel is displaying a mostly-dark or mostly-black image. It's like there's a huge hole of darkness on the top 1/3 of this stupid panel with the bottom half or bottom third or whatever being much brighter. It's extremely irritating and completely unacceptable.

 

Now, before you say, "Oh that's just the viewing angle because it's a TN panel", no, that's not it at all! Like I said, there's a sharp line that divides the darker and lighter areas. Well, it's not razor-sharp, but it's VERY noticeable. I am trying to replace my Samsung 2253BW which is an 8-year old TN gaming monitor and it doesn't have this problem at all. Sure, its backlight uniformity isn't perfect either, but at least its lack of uniformity is very uniform with its uniformity and it's not even really noticeable at all. The top and bottom 1/5th or 1/6th (or smaller?) are the same brightness and both fade very nicely to the center, and the same is true for left and right sides. So, it's much better than this piece of junk called the Acer Predator XB241H. Or maybe I should just be angry at the panel manufacturer and not Acer? I don't know. It really pisses me off though because I paid $394.99 for this damn thing while the 2253BW cost me $299.99 in 2008 and is still better!

 

Sigh.

 

Then there's the location of the OSD indicator for the signal type. IT'S DEAD-CENTER! So, when I start Windows or launch a game or exit a game or change the refresh rate or do anything that forces the monitor to reestablish a connection, I get this stupid solid black OSD indicator rectangle that tells me what signal type I'm using and it's dead-center and thus it's right in the damn way. What the hell was Acer thinking?! It's extremely stupid AND I'M FRICKIN' SICK AND TIRED OF IT!!! I'm sorry, but I live at my computer, and so this is absolutely unacceptable. I'm sick and tired of seeing that stupid signal type indicator thing.

 

Then there's the super-bright (and obnoxious) blue power indicator LED. Good lord. Again, what was Acer thinking? While it's in its sleep mode, IT'S AMBER! It would've been better if they had chose Amber for when it's on and blue for when it's off. I hated it so much that I had to cover it up with electrical tape which means I half the power button and half the main menu button covered in tape which makes those buttons a little more difficult to operate. I hate this stupid monitor!

 

The only good things that I like about this monitor are stupid things like the nice non-glossy bezel, the fact that the buttons are located on the front and are very easy to press (and feel good to press), the stand has an awesome look to it (I love looking at it! The red parts are metal and I think they're anodized red and not painted), and I can raise and lower and tilt and swivel the monitor with ease. Of course, I also love the high refresh rate (I'm using 160Hz and loving it), G-SYNC, 1ms response time, the ability to have a super-bright brightness, and a very decent color accuracy right out of the box!

 

So, if the backlight uniformity weren't a problem and if it didn't have that stupid dead-center OSD signal indicator that comes up every damn time the monitor reestablishes a connection while I'm in Windows (as I described), then I would love this monitor because it's otherwise freakin' awesome. However, I think most of its awesomeness for me is due to the high refresh rate, G-SYNC and the 1ms response time. So, I'm going to return this stupid monitor and get better one that has the same features but without these 2-3 extremely-annoying problems. Except, finding such a monitor is proving to be quite difficult. I don't want a native resolution that's any higher than 1920x1080 because that's about the limit for my sig rig, and I definitely don't want 1920x1080 on a 27" panel because people say it doesn't look as nice as it does on a 24" panel. heh That's ok though because I need a monitor that's guaranteed to fit underneath my hutch (maximum size allowance of 18"x25", but I'd prefer to limit it to about 17"x24"). I absolutely depend on this hutch, so no I'm not getting rid of it. I can't!

 

I'm definitely not looking forward to going back to my 2253BW though because it doesn't have a high refresh rate and it doesn't have G-SYNC. Its brightness also sucks in comparison. I absolutely love setting the XB241H's brightness to about 65-75 for games and movies and full-screen YouTube videos. It's awesome and it's something I have always wanted. For everything else like just sitting here on OCN, I use about 10-20. To give you an idea of the brightness comparison, I'd say that a brightness of 25-35 is about equal to the 2253BW's brightness of 100. I guess that's the difference between an LED backlight and whatever the 2253BW has (cathode-ray tubes?  I don't know).

 

Sigh. So yeah, I hate the XB241H's panel.

Unlucky you're struggling so much. I personally don't have problems with brightness uniformity at all, there's the backlight bleed right next to the bezel around the whole screen, which isn't very severe in my opinion. I heard of your proplems quite often though so I'm assuming it's quite a panel lottery with this one xD

I actually think the screen performs quite well, then again my last screen was a 23" 120€ Benq I picked up when I built my PC and didn't want to spend much more money - because I liked the colours rolleyes.gif .

I agree on the input indicator, weird choice, but doesn't bother me that much as for me it pops up when starting the PC or a game. I personally can't say much negative about the screen. Initially I struggled setting up the colours but ended up using the 120Hz ICC posted here and the "normal" colour setting.
The OSD is a little annoying

So, if yours is displaying nothing but black (like the Blank screensaver), then your backlight uniformity is just fine - even with the brightness set high (like 50-80)?

 

What do you see at the top of the panel for normal use if you enable the "Blue Light" feature and set it to a light setting like 80? Does the top-left corner of the panel become noticeably browner or warmer than the rest of the panel? Even without Blue Light enabled, does the top-left portion of the panel appear slightly darker than the rest when it's displaying nothing but white?

Yeah, as I detailed quite thorougly, my monitor also had this problem, even after its LCD panel was exchanged by Acer repair. The backlight uniformity is just very bad, you have the in comparison very weak backlight in the top left area and the in comparison very strong backlight in the bottom right area. This makes colors change, if white content is viewed the top left area appears brownish, for example.
Then there also is the very large amount of backlight bleed in the bottom right area at the full 180Hz refresh rate.

This may all be okay for someone who has always used similarly bad monitors as this, but I, who used an Eizo FG2421 which has more or less perfect backlight uniformity prior to the Acer XB241H, noticed the bad backlight uniformity a lot, and it really was an ugly picture to look at.

Yeah, I think I'm done with this stupid monitor. lol

 

I've been waiting for the ASUS PG248Q to be available here in the U.S. (it's at Best Buy, but I'd have to pay about $35 in tax and I'm already looking at about $40 to ship my monitor back). I know it uses the same panel and so I'm sure this is a risky move, but I'd rather do that than exchange this for another XB241H or have Acer replace my panel. I'm going to miss the cool Predator monitor stand, that's for sure. I won't miss everything else though.

 

I swear though, if the ASUS PG248Q that I end up with has the same problem, then I'll return it saying it's defective because that's usually when a store will pay for your return shipping. I can't live with a monitor like this. If my computer were more of a thing that I used for just a short time every day, then yeah I'd probably be fine with this.
