PG48UQ firmware v29 awful HDR

Doctor_Headlock

Posting this here as well as in the PG/XG series monitors forum, just in case one is the wrong area

I saw earlier today that there was a new firmware available for the PG48UQ addressing supposed HDR issues, but upon updating the HDR now looks worse than ever. I was unaware of any HDR issues with the existing firmware, only the problems with screen flickering, sometimes it won't wake from sleep and brightness flickering when g-sync is enabled. Now HDR content is completely washed out, dark areas are too bright, the screen turns grey when an all black screen is displayed, shades of blue are now grey, and everything is just completely wrong. Anyone else want to weigh in?

I tested everything again with HDR calibration app - Windows HDR Calibration
And nothing has changed - HDR on the V029 looks terrible.

What's the content source? Might help service if you provide a few.

Make sure not to use rips or anything of that nature. Use examples from  HDR content from Amazon or Netflix etc.

Better find at least one person here for whom HDR works well after updating to V029.
For me it doesn't work well on any HDR material. Even the Windows desktop looks bad in HDR.

Not particularly helpful. Would you be in this thread if it were working satisfactorily for you?

Ok, thanks. We'll take your word for it then. 👍 In that case, roll back as customer service has instructed

I have the exact same issue with v29 on my PG48UQ. Same washed out effects as in your image. It’s as though the blacks don’t get black enough any more and you get that washed out fuzzy grey effect.

 

I’ve tried recalibration etc, no joy. Desktop colour accuracy looks marginally better than in v29, but HDR is unusable.

Same issue here, HDR content is broken on V29. Greys are washed out with a weird color rendering. BTW SDR seems over saturated.

I reverted to V28 which is not so great either but it is fixable adjusting digital vibrance from Nvidia panel

Wow I'm glad I saw this thread before updating my PG48UQ. Honestly the HDR is garbage on this monitor, but HDR is garbage PERIOD. I don't use it on anything, all HDR does is sacrifice color for detail, I'd much rather view my monitor is every situation with HDR off. HDR is a marketing scam.

This monitor looks so ****** good in SDR why would I mess with it? Have you seen real 4k video on this thing??? It's insane.

I think I got really lucky and firmware 28 fixed most of my flickering issues, on the one before 28, I think 27, I would get the screen going off for a few to 30 second constantly, I mean it was absolutely unusable. Since updating the 28 I've seen it happen a handful of times in the last 4 months. I run the monitor 24/7 and I pixel clean every time the monitor warms me, which is 2 times a day. I've noticed ZERO image retention. I bought a LG 65" B series OLED TV in 2018 and used it as a monitor for a year, I had to get LG to come and replace the screen (at massive cost to them, they sent a tech up from Tacoma to Seattle to replace it in my home! TWICE in 1 year! The burn in was so bad you wouldn't even believe it.) I ended up selling it after the second time. But this thing, being on 24/7 on windows with the icons in the same spot, has not even a hint of burn in. It's REALLY impressive. This is a VERY high quality panel they used on these. I mean I'd hope so for $1500, but ya, it's legit. But ya, forget HDR, HDR sucks anyways.

I'm no scientist when it comes to measuring HDR, but I've got pretty good results (for how garbage Windows HDR is) now with firmware 28. Definitely prefer it over SDR, as the colours appear so much more vibrant in most content. I have three friends with the Gigabyte Auros and same panel and none of them touch HDR, and echo your sentiment. 

Not sure where the answer lies to be honest but I'm sticking with HDR for now, and definitely not firmware 29.
