Just bought a Asus ROG Swift PG279Q monitor. The white balance/brightness uniformity is disappointed for this kind of premium screen. Search online there are lots of same issue reported as well. I will try to test using the X-Rite i1display Pro colorimeter tonight and post the result here.

Just would like to know, can I return/exchange the monitor in this case?

BLB is minimal, and is alot less disturbing than yellow tint on certain portion of the screen.

Still the same question, in Malaysia are we able to return/exchange if user is not satisify with it? This is a premium panel that cost RM3.5k hard earn money.!!!

Hi.

Please see the screen shot below. I using Nikon DSLR to capture, both monitor and camera had been vertical and horizontal aligned with bubble level meter. Please note that i purposely adjust the camera to be slightly out of focus to blur the image a bit, if not the banding will affect the image outcome.

Grey
You can see the 1/3 of the left side is noticeable warmer/yellowish than the rest


White
Again the same area.


Mix(gmail) with grey and white strip. This is most noticeable in this situation as you can see the 1/3 of the left side colour significant different with center and right.


I can't ensure you will see this photo on ur screen because you need a reasonable good monitor display to spot tge different. I using my Samsung Galaxy S7 edge to view it and it is close to what i saw by my eye. My i1display pro colorimeter shown 500k temperature different across the left side and right side, which is tally with what i saw.

Please let me know what should i do. There are alot of similar complain worldwide and some of them even RMA 3-4 times before they get their 'golden' unit, u can find them easily by typing asus PG279Q yellow tint in google, it will lead you to the Asus ROG forum.

Guys, exchanged my PG279Q yesterday and guess what, same left side yellow tint problem on this new unit, panel manufacturing date same July 2017 as previous returned unit.







Measured using i1display Pro colorimeter reveal the exact truth that seen by my eye





I'm going to return the 2nd unit and this time ask for refund, the shop understood and approved my request. This is a joke consider how expensive the panel was.

Know what, until now no reply by the so call 'Asus Malaysia technical support' in this thread, is a completely joke and you definitely loss ur potential customer here.

My main issue here is not the backlight bleed or glow, this 2 i can live with it because the effect on real world application is minimal, i do not have these issues in both the unit.

The main issue is the yellow tint, aka white point uniformity of the screen is damn poor. It causing a half yellow half white during browsing or in desktop mode with white/gray background.

Anyway thanks for your reply and today i successfully returned and get it refunded as well.

Thanks for the compliment, i thought i'm too picky on this issue but it.seems obvious to you too.

I understood nothing is perfect in this world, and this monitor is aim for 'gaming' as it named, but doesn't mean it could be that sucks in browsing or regular work in desktop. I tried to convince myself to accept this becos i don have time to do all this kind of time wasted RMA, but hey once i wake up in the morning my 1st mind was i bought a premium panel with hefty price and give me such shitty quality...so end up return it.

I can accept some white balance runs off on the entire screen, provided it perceived 'balance' on the entire screen, not this kind of half-half shit...and this is my 1st time buying such expensive monitor, even my 60'' 1080p TV bought 3 years ago was cheaper than this, but hey that one at least don't gave such headache.

I had exchanged my Samsung Galaxy S4 before, discovered red tint half the bottom screen (yes, imbalance stupid tint again) right after i unpack at home...i always lost in panel lottery.

Yes you are right, in fact the perceived yellow tint is worse than what
It shown in the photo. I can clearly see half of the grey out email were with yellow tint while the right half with 'normal' grey. The yellow tint also causing the lowyat forum light blue background become light green at the left half. The perceived white balance is distracting when the same colour across the horizon from left to right.

As i mentioned, good in gaming is not means it can be sucks in non gaming. This is my reason i can't accept that.

I received the 1st monitor on last Tuesday, exchange once and returned eventually yesterday where the whole process was less than a.week. Can't say the customer.service is bad. But the credit go to the shop that i purchase, not Asus Malaysia.

I don't know, impressed by the G-Sync, high refresh rate and good colour of IPS, which don't have much choices now at the moment except Acer and Viewsonic which using the same panel from AUO as well. If not the yellow tint issue i woould have very happy now. But survey shown Viewsonic had better QC overall, let see how.

1st unit H7LMQS093055, 2nd unit i don't even care to look at it as i know i will get it refund. Both manufacturing date code July 2017, from Brightstar Lowyat Plaza.

Anyway, kindly share your finding on those units if you have. Thanks.

I still love 16:9 aspect ratio, and ultra wide 1440p will have unneccesary burden on my rig. 2560*1440 just good enough for my GTX1080 with decent framerate.

I got my NON ASUS 165Hz G-Sync IPS gaming monitor today.

Let's see the white uniformity.

Damn good compare to Asus. Although the surrouding is warmer than center point, but is within 200k hence perceived balance.

NON ASUS




ASUS




ASUS, this is what we called 'good uniformity'.

Try to guess what brand ( ) is that...not many only.

Ur statement doesn't make sense to me and the article was all about the over exgregated BLB issue accompanied with alot of misleading over exposed photo. You never even explain why each of the technlogy can contribute to such issue and no one can explain it so far, but some how you try to make such pointless conclusion.

Please note that i'm talking about the imbalance yellow tint, not 'uniform ' yellow tint that can be solved easily by calibration. You never saw that before i guess, left half yellowish and right half blueish and is damn distracting in plain colour browsing mode. FYI, the 2 units that i returned come with minimal/almost perfect BLB level, and i did press the bezel and saw the bleeding moving, but it did not change the imbalance yellow tint issue. So what you said is just a baseless speculation.

We all known currently only 4 companies make use of the same panel from AUO, which is '3A's and one 'V', of course all shared the same issue, but the problem is, the QC among those manufacturers are different, what i researched online through various feedback from forum, Asus is the worst in terms of QC...they should reject whatever unacceptable instead of let buyer playing with panel lottery.

And one final question, which shop is willing to break the seal tape to let you test before u buy?

I'm not pursue absolute perfection, the model that i got today not perfect as well, but i can accept that mainly because the previous 2 units were much more unbearable.

The reason why people call it as 'panel lottery' is because can't test before they pay. As simple as that.
