A GeForce RTX 2080 Ti should work too.

@fallen you should be in the Potplayer forum not here.
@foobar no it does not, you'd probably be fine with a 1060.. but 1070+ would be good.. I'd wait until the 20xx cards drop before buying anything though.
@foozor extra 50% performance over 1080Ti *Drool*

Not sure what seem to be the problem. Downloading few more HEVC encoded videos to test it now.
Edit: nope potplayer still shows everything NV12
I'm pretty sure that potplayer's internal codecs are forcing this output...

No, I have 1070 and I upscale to 2160p then downscale to 1440p.

Everyone will give you a different version.

I use 385.28 because that the one with the least issues with my display (see sig).

Can you select 12bit with a custom res?

The only way to get 12bits with custom timings is calculating your timings with MadVR and using Custom Resolution Utility to add it to your driver.

Go a few pages back, I've explained how to do it and it worked for me and at least one other user.

Is doubling better than image upscaling in your case?

My TV has more banding with >8 bit so I do not want 12 bit, but no, I cannot use 12 bit with custom resolutions. >8 bit is the least important aspect of getting the image to the screen but it should work.

isn't 12 bit just 8 bit/10 bit adding zero at the end of signal??

Yes. Doubled 720p is exactly 1440p. Quadrupled 480p becomes 1920p so it has to be scaled down. But due to scaling amount NGU makes it much better than other methods.
On the other hand, 1080p probably doesn't benefit much from NGU (I haven't tested), but I use it anyways.

My question was about 1080p movies. In my case I'm with a 29 inch 2560x1080p monitor. So for me image upscaling is OK, I was wondering if doubling will benefit.

In high bitrate case Antialias loses fine details. Sharp and Standard are much better in this case.
Jinc produces similar results, but edges aren't sharp.
In the end, unless you pixel hunt in screenshots there is no visible difference.

Edit: I tried to attach screenshots but they got scaled down so no reason to attach them.

Attaching images in the forum could take forever to be approved...

I thought so too but maybe not. You want 100% to be the same and 111111110000 is not 100% in 12 bit. There are several ways 8 bit could be converted to 12 bit.

I fixed it by disabling all the checkbox on the 8 bit in Lav Video Filter settings.

It still works fine for 8 bit and works with P10 with potplayer.
