Here we go again the comparing that x34 with the asus, is there anything else to talk about on the pg348 other then dumb scan lines and repeating the same damn thing.

Looking at that zoomed image taken from KitGuru review, all I am seeing when looking at the original zoomed to 1:1 are rows of emitters separated by their placement mesh though the polariser, causing the eyes to see the small serration lines, and its uneven because you would have to line up to each individual emitter with the camera or human eye perfectly to get an even output, which of course is impossible with a curved display, and not perfect with a flat display.

People still complaining about scan lines, but only when their noses are pressed up against the screen, I think are being way too critical, and this is coming from someone that's really critical about the smallest fault with anything I purchase.

If you can still see these scanlines at normal viewing distance in work or gaming, say 50cm +, then it would definitely be an issue for me, but no one plays or works with their nose pressed up against the screen, and if they did ,they would be clinically blind by their 30's. I’ve seen scanline problems in work that people really should scream about, but this is really not worth loosing one ounce of sleep over.

As for colours being vibrant, I have to agree, after calibration they do look a little dull, but I did find the answer, or at least an improvement.

I tried calibration out of the box, 60hz, 100hz, Gsync enabled, disabled, even SLI.

I tried calibrating from various gaming modes, from racing, to sRGB, but always got dull colours.

After calibration the greys were always perfect comparing against my Dreamcolour X, and colour balance was also perfect, but still dull.

I am not expecting this monitor to match the DreamColor X as it can get 100% sRGB, 100% Adobe, and 95% ntsc

So I did a little searching about calibrating a curved display.

And found the solution, Its still not as vibrant colours of the DCX, but its definitely better than previous calibration attempts..

Because current calibration devices are designed for flat LCDs, you are going to get a little leakage out of the sides, even if the monitor is tilted facing upwards, and you have done your best to make sure its flush to the screen, so its best to take a room light reading in the daytime, and calibrate at night, but that's not enough..

You have to make sure its pitch black, and no other light sources in the room, no keyboard or mouse lighting affects, no other monitors etc, i'd even go as far as to say, wear a black jumper :-)

I set the monitor to default setting, chose Normal colour temp, and then calibrate.

Going though the calibration sequence, its already obvious that this monitor is capable of producing vibrant colours….

After calibrating in those environment conditions, the vibrancy of colours was much better, but still not as good as the DCX, but acceptable.

Also when enabling / disabling gsync or sli, windows reverts to its default calibration, and icc profiles have to be reapplied. Its easy if you have something like datacolor profile chooser, just takes a second to correct, but this has been an issue since late last year, and will also happen when coming out of a game with its own colour settings, , Microsoft as far as I know are still working on this problem.

So one member reporting that colours are even worse when in gsync may not have realised the icc profile has switched to default, and needs re applying.

blablabla...
If you don't understand why I mention X34 because both monitors share at least 90% tech specs, then I can't do anything for you. I only suggest you to ignore me and I'm sure you'll feel better.

SRplus --> I thought about ICC profile not being loaded when switching Gsync / Overclock but this is not the case in my situation. Also, it would not explain why the same thing occurs in game since ICC profile is not working in 3D.
About scanlines, I can assure you that I am not exaggerating. I remember that 2 days ago, I disabled SLI to make fps down to 35/45 in Witcher 3 and if I could saw scanlines at ~30cm from the screen, it was ok at 60cm, my usual sitting distance.
It was enough for me to keep the monitor but now, I can easily notice that one half of the screen is perfect and the other one is "noisy" because of the scanlines.

I will post some photos later after I'm back from work and I hope you will understand why I can't deal with such a defect.

Here's what I got playing around with photoshop and x3sphere pics:


At first I was trying to accentuate scanlines (brighter horizontal bars on right part) for people who can't see it.
I failed, not a photoshop pro. frown.gif

However I realized that:
- when you zoom you can't really see the difference.
- when you match contrast, brightness and hue, you can't really see the difference.
- may I add that, when you stare at those pics for too long, you end seeing nothing and everything biggrin.gif
Thus, I assume scanlines are like interlacing: you mostly see it on moving image, and from an average distance.
Being too close or looking at a fixed pic might prevent scanlines detection.

My 2 cent guess-work.

That is significant IPS glow, but you are right - in most gaming scenarios, it's hardly noticeable. The one game that I do notice IPS glow the most on my Acer X34 and AcerXB271HU is EA's Battlefield Hardline single player campaign. No other game, even Tomb Raider where there are a lot of dark scenes do I notice the IPS glow. Regardless, the IPS glow is quite evident in your photos so it's definitely not a perfect monitor.

From the sounds of what you are describing, I'd definitely consider an RMA.

In regard to Witcher 3.

My MoBo had a problem when I first got the PG348Q in that the primary GPU would only run in Gen2, the other three @ gen3. But that turned out to be a bios problem, reverted back to the previous release, problem solved. . So testing things like Tomb raider, Ultimate settings, no other changes, Vsync off, at 3440 x 1440, I was getting Min 87fps, average 96fps, Max 110fps, Now I am getting min 96, average 111.5, max 128fps. amazing the difference one card running at gen2 can make.

But I have tested witcher 3, and even with 4x Titans my system struggles on max settings and I'm getting around 20fps, really sad frown.gif but expected.

Its strange that a game like Crysis 3 can run at ultimate settings with a good fps rate on a 3440 x 1440, yet witcher 3 even on medium or low settings which makes the game look a lot worse graphically than crisis 3, still struggles, so i'd conclude from this that Crytek are much better coders, and better at optimising textures and poly count in games, than CD Projekt RED...

I've been tempted by the Titan X since its launch, and definitely need the extra vram for work, so would choose the Titan X over the 980ti, but 46% performance increase didn't seem worth the £4K to replace my old Titans. Now I am in a place where I wish I had upgraded to Titan X , but too close to Pascal, which after the GTC will most likely be getting a release date of late May / June IMO.

I really enjoyed witcher 2, haven't tested it on the new monitor, but I'm guessing it will have similar results, Crysis, Bio Indicate, dishonoured, Tomb Raider etc, all run at good fps, same about witcher 3. Its definitely that my system needs an upgrade, but I think its also that Projekt Red need to up their skills..

The G-Sync scanline issue has been well documented for this LG panel (thanks to early adopters/owners of the Acer X34). The cause is a defective G-Sync module and the only fix is to have it (the module) replaced via RMA or exchange for another unit that does not have a defective G-Sync module.

From what Dr Mad is describing, it may be a definite scanline problem that needs RMA, but from some of the images I've seen posted here and other places, I think some people are being way over critical, seeing the lines only with their noses pushed up against the screen, and there have been a few on here and again other places mistaking moire patterning from taking a photo of an LCD or looking at a high res photo scaled down as scanlines... I think this problem on the PG348Q and X34 has been blown up way out of proportion so far. But still horrible if you do end up with a naff gsync module, where the lines are visible at normal viewing distance, at this price point, would definitely RMA....

Not at all, the cause is NOT a defective g-sync module:

 In regards to the scanline issue, I have been provided with an update. Scanlines are an effect caused by rapidly changing refresh rate. Variations in the refresh rate create an increased holding time that results in the accumulation of an electrical charge. When this charge is released, it causes small variations in the frame that result in faint horizontal lines.
 
We certainly appreciate everyone’s patience and the feedback that has been provided by many of you. Unfortunately, this is a side effect for cutting edge technology and while there is not a fix to be applied, we will continue to make efforts to minimize and eliminate these types of limitations in future releases.

I wouldn't generalize and state that the scanline issue has been blown out of proportion for every single incident. Some monitors have the issue worse than others, so it comes down to a case-by-case basis. If you have to smash your face against the monitor to barely notice the scanlines vs. being able to see them easily from 3-5 feet away, then it could be argued an RMA may not be necessary. But, I do agree that at this price point, the monitor should be near perfect and not have the same defects as monitors that are almost half the price.
