PG27AQN/XG27AQM DSC questions

Post by prod1G » 13 Mar 2024, 16:12

What's the highest Hz the PG27AQN can do at 1440p with DSC turned off?
Bandwith wise DP 1.4 should do something like 290Hz at 8bit?
Would appreciate if users could try this out and report back :)

It's 240hz as far as I'm aware.

So no custom resolutions with CRU to maximise bandwith without DSC?

Thanks for the info!
I have another question related to DSC.
I got a XG27AQM and it still shows DSR when i put it in 270Hz 10bit RGB. Shouldn't it max out the bandwith, enable DSC and disable DSR?
There is no DSC toggle in the menu. Is it always running DSC, even in 8bit?

There's no info I can find on DSC functionality for the XG27AQM, and I don't own it, so can't test.
