Question I'm looking for a specific monitor with DP 2.1 ?

[Elliah246]

The ASUS ROG Strix OLED XG27AQDMG has nearly perfect specs.
2560x1440p
240Hz
10Bit color depth
OLED
0.03ms GTG response time
FreeSync and Gsync compatible

But it uses DP 1.4 and thus will use DSC-datastreamcompression where i don't know if this is truly visually losless quality, but would rather avoid it with an equal monitor that instead uses DP 2.1
Is there any such monitor yet from Asus or another brand?

There is the Asus PG27UCDM using DP 2.1 but this model also uses 4K resolution which is not what fits my GPU.

Is there a list of monitors with DisplayPort 2.1, preferably WQHD + 240Hz or 360Hz and OLED ?

I asume if there was anybody out there who knew about such a monitor i asked about they would have commented by now. Damn

I don't keep up much with the latest releases anymore so I can't help much with shopping recommendations. Not a helpful response I know, but didn't want you to feel ignored.

The DSC algorithm is public and VESA provides a reference encoder for anyone to use. So if you'd like, I can compress any still images or screenshots you want with DSC so you can do a visual comparison yourself. No need for uncertainty.

alright alright, be happy with whats on the market now or wait for future releases, yeah whining about something that doesnt exist makes apparently zero sense i know.

i was looking for comparison on youtube but didnt find any professional looking videos.
is the reference encoder easy to use? otherwise i asume will just ask you to show some results with and without dsc?

Comparison would need to be done with still frames. It's not practical to compare with video except by seeing it in person, because you need to see the uncompressed video as a reference.

Any video hosted online will be compressed with like 500:1 AVCHD so you'd never be able to use that to see what DSC looks like compared to uncompressed video. An uncompressed video file would be, well, close to what you would get out of the calculator from the other thread. At modest settings of 24 bits per pixel × 1920 × 1080 pixels per frame × 30 frames per second = 1.5 Gbit for 1 second of video.

The reference encoder uses a command line interface, you give it an image file, it compresses it, then decompresses it and gives you the resulting reconstructed image. You wouldn't be able to use a normal JPEG or something like that for similar reasons, normal image compression is significantly heavier than what DSC applies so you need to have pure uncompressed images. The encoder only takes PPM files which is a (I suppose somewhat obscure) uncompressed image format. Provided you have images in the right format though it's not too hard to use.

Anyway a long time ago I wrote a MATLAB script that would take normal PNG images (lossless compression). Behind the scenes it just converts your PNG image to PPM, feeds it into the encoder, and then converts the output back to PNG for you. And it also generate some helpful comparisons images.

This is an animated PNG that flickers back and forth between DSC and uncompressed. The legend is in the lower left.

It also produces a side-by-side showing the original and compressed, along with the difference between them (actual difference, and then amplified so you can actually see it).

A lot of those monitors with stats like that Have HDMI 2.1 which can do 1440p 240hz without DSC. 360hz is questionable, and maybe something like 300hz would work without it.

I'm using HDMI between my 3080Ti and 1440p 240hz OLED.
