Question

GPU acceleration required for HDR display?

On a PC Win 10 Pro using Nvidia GeForce GTX 1080 Ti graphics card. Displaying to my TV via HDMI at 4K.

If I dare to turn on the GPU in Lightroom preferences, UI performance becomes impossible. Pop-ups will half-appear. I can click on a button and nothing will happen for tens of seconds. Drop down menus will flicker.

I'm unsure what might be the problem. I'm not overclocking or otherwise doing anything strange. I worked with an Adobe tech but once they saw that disabling the GPU fixed the issues, they pushed back and said my system is to blame. Except I can play games without issue.

I'd live without the GPU except then I can't use HDR.

Thanks!

Are you sure that the screen is not the issue?

In your latter reply you mention getting HDR to work. I suspect it will not with that screen.

I am assuming you are referring to HDR treatment, not Merge Photo HDR.

I only meant that viewing photos in HDR is only supported with GPU acceleration turned on, but turning GPU acceleration on breaks Lightroom.

Just hoping to get someone with an idea. I cancelled my Lightroom subscription because I can't get HDR to work without the GPU working.

You're using Lightroom Desktop 7.2 not Lightroom Classic. Therefore, I've moved your thread to the Lightroom Cloud forum.
