You will have to turn off many of the madvr's features in order to scale 1920x1080 into 3840x2160.

Madvr will still give you more color accuracy, but to use higher quality filters like Lanczos, there's simply not enough processing power to do it.

If you scale 1080p to 1080p, then that is chroma scaling only, 1:1 luma. the 4400 will do this perfectly fine. You can enable Jinc or Lanczos for chroma.

What about image doubling, would that require less juice than upscaling ?

So you can convert the DisplayPort version 1.2 to Hdmi 2.0 or 2.0a ?

If this works, how about my Dolby Atmos audio ?
Would my Dolby Atmos audio work through such an adapter ?

Letting the CPU decode the first part is fine.

Thanks guys.

At the moment I believe the screen is set at 24hz.
I can go up to 30hz.
The higher the better ?
Should I set it to 30hz ?

Would 60hz with the adapter give me better quality and smoother playback ?

Thanks in advance.
