Haze value is sometimes specified for particular panels, but it only gives you an indication of the level of diffusion. Screen surfaces have different layering structures and textures regardless of this. You can have some fairly low haze surfaces that look grainy and vice-versa.

I see, thanks for the explanation.

Thanks, going to try it out.

Perceptual gives the best colours and in darker areas clouds and light haze has less banding with 32x32x32 3d lut size whilst

Absolute colorimetric white point scaling (default) had less vivid colours. These are just my observations.

Like to hear yours.

I did as you suggested, but I found it a bit hard to Alt-Tab from a full-screen game to just change the .png used... So I rewrote the shader a bit smile.gif

My version expects 2 .pngs instead of 1:
  • ColorLookupTable32.png - 1024x32 pixels - 32x32x32 setting in DisplayCAL
  • ColorLookupTable64.png - 4096x64 pixels - 64x64x64 setting in DisplayCAL

This version of CLUT starts in the off state, you trigger the 32px one with Insert and 64px with Home buttons. They are not exclusive, so be careful not to trigger them both at the same time or you'll get a very dark image! No warranty, 5min hackjob, etc. wink.gif

clut_double_test.zip 695k .zip file - modified version of CLUT from DisplayCAL for ReShade

This file contains my CLUTs with Perceptual Rendering intent, Gamma 2.2 Tone curve. They were generated from a 10h overnight run.

S2716DG12016-02-0302-26D65002.2SXYZLUTMTX.zip 1479k .zip file - profile from which the LUT was generated, 20 brightness, 70 contrast, 98/99/96 RGB

I found that the 32px version indeed generated less layers of banding, but the bands themselves were way sharper than the 64px equivalent. It seems to be a matter of precision, as expected. A good test for that seemed to be the options menu in Heroes of the Storm which has many shades of blue/purple in the background.

The perceptual intent indeed looks nicer, but I'll stick to the 64px smile.gif

Are there any downsides to plugging mouse and keyb to the monitor? Any increased lag?
I mean, the signal is going through an extra thing now, instead of connecting straight to the pc, it would be pretty awesome if there were no downsides.

I have seen some hubs that had a noticeable impact(it cut the polling rate too and this is the primary think I noticed.), while others are not noticeable to me.
I am sure it is all noticeable to some users and test equipment will see it for sure.

Some motherboards have dedicated usb ports that try to cut down on as much latency as possible, if your board doesn't have such ports use whatever usb is available directly on the mobo. I wouldn't plug in a mouse/kb to a monitor and have the upstream take it to the mobo, without a doubt there will be some added latency, how much i don't know but i rather avoid it entirely. Use the monitor usb ports for thumb drives or charging external devices or to power something like bias lighting on the back of the monitor etc.

EDIT: On that note i'm fairly interested in this model, i'm a little worried about the matte coating, and wonder how easy it would be to peel off. The VG248QE i did was painless and really made a huge difference in picture quality. Assuming i got a good panel and let it burn in for a month or two to make sure it was all good i would probably attempt to remove the coating. As nice as IPS screens are the glow really kills them for me. Gonna ponder on the idea a little longer.

Apologies for the double post, but for those who own the monitor and are running it at 144hz with OD set to normal, is the overshoot noticeable at all? Looking at TFT's review i see that the monitor has the highest overshoot with whites, not sure how noticeable it really would be in practice.

I've plugged in my g400 to the monitor, with the upstream cable and I don't really notice any lag. mouserate.exe shows my mouse going up to 1000hz. Are there any programs to test mouse lag?

Anyways, there's a really annoying issue I have with the monitor right now. Monitor nevers come out of idle with deep sleep enabled, with it off it comes alive instantly with mouse movement, but then it flickers a couple of times, more like it turns on and off a couple of times and all my windows would move back to the primary screen. This happens every time it comes out of idle (windows+L). Wonder if it's because my secondary screen is a different solution and refresh rate.

Edit: Ok, yeah I unplugged the second monitor and that doesn't happen anymore. Do I have to match resolution and refresh rate on both monitors to get it to act normal? My second monitor is only 60hz.

cleaver way of doing it. I was just talking screenshots, creating a new 3dlut and and comparing screenshots.

The banding for me is still there in dark areas but just has fewer layers.

To get a profile with high contrast ratio and low black luminance I had to move the colorimeter off centre from the screen but was told that placing it on the center is standard so I just stuck with that..

Mads1 try this new profile and let me know if it is better.

Mads I have included a version 2 of the 3D LUT in this folder. It uses a different rendering intent which I think looks better and whilst it does not eliminate banding it does smooth it out.

Default settings of the screen is :
Brightness 75
Contrast 75
You will be unable to tolerate light on white background.
The level of discomfort will depend on the sensitivity of your eyes by bright lights. Most people will reduce the brightness to 30 others to 20.
I Had to set Brightness 20 Contrast 50 with Yellow's ICC profiles for avoiding eye strain when working with word or browsing on web.
