As for choice of Movie Resolution. 4K is ALWAYS better than 1080p at ANY Distances due to 4:2:0. it's the only way to get 1080p chroma.

Things are different with a projector-sized screen. Projector owners see a lot of benefit with 1080p -> 4K upscaling.

well yea, projected is usually much larger, and bigger pixels.

Although from what I've seen of NON-native 4K projectors, the pixel shifting has an effect similar to analog upscaling (scanning), In that case, I'd say again NGU may not be so necessary, since it's not producing the intended NGU output anyway.

For most TV sizes/ distances, its' ok to go Green.

Yes, you'd want a native 4K projector if you placed a premium on upscaling. Even then, many are using very high settings for image upscaling and derive a lot more visual improvement than say a 55" 4K TV.

I am not sure where to ask it, but I think it's probably a Windows or maybe NVidia thing?

I set up a HTPC for a friend, but for some reason, whenever a video opens or closes (Like starting a video in MPC-HC or then closing MP-HC itself) it causes his display to have to re-acquire it's signal.

This is pretty annoying as he has an older JVC (RS600) with a near 20-second sync time.

Now, I am completely familiar with refresh rate switching and such, but I have all of that completely disabled. I have the HTPC set for 3840x2160 23Hz RGB 12-bit (tried 8-bit as well). Refresh rate switching is disabled in madVR and disabled in MPC-HC.

Any ideas of how I can have it so that the JVC doesn't need to re-sync every time I open and close a video?
Well, I figured out the screen re-sync issue.

It was a combination of software and hardware.

It happened when using in madVR calibration tab "Report BT2020 to display" enabled and when sending the video through a Marantz 8802.

If we send the video to the JVC RS600 directly, it never blanks with "Report BT2020 to display" enabled, or if we send the video through the Marantz 8802 with "Report BT2020 to display" disabled it also never blanks.

But send "Report BT2020 to display" enabled into the Marantz and it blanks every time opening and closing a video through madVR.

Weird!

I also have that option enabled and send my signal through a Marantz SR6010, but I don't have that issue, also use an RX2070 (latest driver)

So double weird :-)
