ASUS ROG PG279Q and PG279QR Question

Hey all.

I purchased the PG279Q and noticed that all the whites on the panel looked very yellow. I tried multiple fixes that I found via a Google search to this known "issue" but none of them worked. I sent it back and instead purchased the PG279QR and while the yellow effect is a lot better then the IPS panel, it's still present. While I LOVE the gaming side of the monitor, I also use it a lot for the web and videos and the yellowing is annoying. I've read that it's either defective, a QC issue, or is fixable, except that the fixes I've tried haven't worked. I ran a color calibration via DisplayCAL and a Spyder3Express and it didn't change anything - in fact, it was pretty good out of the box according to the software.

I was just wondering if anyone else has had this problem and if they have a fix or work around for it? The picture I've attached shows the PG279QR on the right and an ASUS VN247H-P on the left.

Any thoughts/comments/suggestions would be appreciated!

good question. I'm also looking at the PG279QZ, which is the updated version of the PG279Q... and wondering if the QC issues were fixed in the latest revision.

Does it allow you to manually adjust the RGB values? Looks like it has a warm push. Try to decrease red or green and see what happens.

RGB values always need to be adjusted first to get as close to 6500K. I would then redo the calibration. Otherwise, you're calibrating it based off of values that either give you a warm or cool push.

Edit: You don't by chance happen to have Low Blue mode activated do you? Either way, the picture definitely looks like it's lacking blue (or red or green is over saturated).

This. Make sure Blue Light Filter is set to Level 0. You may have to recalibrate the screen after you do this. Also, go into System Setup in the OSD and turn ECO Mode off. Make sure any settings like Dynamic Contrast are disabled while you're at it.

I decided to pull the trigger on the PG279QZ, this morning. *crosses fingers*

First, thanks for the input and tips!

I messed with the red and then re-calibrated, but lowering it makes it look more blue, but not more white.
I triple checked Blue Light Filter and it's set to off, or Level 0. OD is set to OFF and so is Adaptive Contrast Control. Dark Boost is set to None. Color Temp is set to Normal.

I've got a email in to Asus, so we shall see what they say. Until then, I got a new DisplayPort cable on the way in and will try that. I have until end of Feb to either figure it out or send it back. This has got me questioning every screen in my house now though - Ha! I'm going around checking settings on everything and my wife is probably ready to have me committed.

Zefram0911, hopefully that newer version works. If it does, PLEASE let me know and off to the store I go!

To me in the pic the PG279Q looks actually a lot more accurate. The VN is way, way too blue. I think what might be throwing you off is this comparison. You are used to a screen that is very blue but appears bright and cold white and when the new screen is actually more accurate it appears as if it's too yellow or red - a warm white if you will.

The panel in the PG279Q actually oversaturates the green channel, if I remember correctly. So try bringing R and B back up and adjusting G down instead. TFT Central set G to 90 or so in their calibration test, I believe, with B and R set at or near 100.

Now that I look at it I think you're right. The one on the left looks like its color temperature is way too cool.

Asus responded with a pretty basic set of stuff - update drivers, try a new cable, etc. They did want to setup a phone call, so we shall see.

Kasakka, what you point out makes sense as well. I've plugged my laptop into each monitor and TV that I have and yes, the VN is a bit on the blue side. But the PG279 is still yellower (Or "warmer") then everything else I have. I know it's not an apples to apples comparison - different cables, different settings, etc.

Armenius, I appreciate that input as well. I tried the green adjustment as well. It helps a bit.

No joke, I'm questioning my eyes in everything now!

Just to update, Asus tech support said it's a bad panel and to send it back for a replacement. I appreciate the input and suggestions.

Zefram, how does the new version look? I'm thinking that if it's decent, I'll give it a try - either that or go the different manufacturer route.

Because of the midwest cold vortex, my monitor got delayed by 2-3 days. I just received it yesterday. This is the best monitor I've ever had.

No dead pixels, no blb... maybe I just got lucky, but I'm quite pleased with it. Out of the box settings on sRBG looked quite good as well.
