Well, ok....you obviously know which player I use. Is this something I have to worry about with madvr in JRiver?

Not usually. Things only get tricky if you mix screens with different scaling values. And the madVR OSD would tell you the resolution that madVR thinks its rendering to, if thats not the real screen res, then you know something is wrong.

Obviously, you put everything you can into Luma, then consider chroma.

If it's downscaling, then it really doesn't matter what the chroma is because you're gonna have enough power to ngu both.

In the case of NGU then downscale, Unless it's from a very very small resolution to slightly higher than native res, then downscale, it doesn't really matter, because NGU makes posterized edges on these. And from a distance they look the same as cheaper algorithms

What to do!?
Manufacturer of TV? What Firmware version?

I'm using image doubling for 1080p, then downscaling to 3440x1440p.

There's a known bug introduced in firmware version 1290, last working was 1270.
Please try and play a 25fps file or 50 fps file and play it at 50 Hz. Picture should be also cut off.
The only refresh rate which is fine should be 60 Hz.

And what HDMI mode do you use? I assume PC mode for 4:4:4 color / RGB support.

Thanks for the reply... Typical swift Samsung updates to fix issues!
Seeing the issue on all refresh rates other than 60hz, correct.

Yes, PC mode on the HDMI input...

There is resizing in the nVidia control panel, but as I mentioned earlier, it isn't shrinking the overscanning, it's reducing the resolution... Which I don't think is something I wanna do. Native resolution only.

Yes you are right that you cannot fix this issue in driver settings on the gfx card, because the TV is simply cutting off the picture called overscan. I personally never really understood why TVs which only have digital inputs anymore have the overscan feature built in.
All HDMI signals I am aware of are free on anything that needs to be cut off other than old Video from VHS for example

Cable boxes which receive broadcast with bad edges. None of us watch cable. but many still do.

I guess that makes sense... The TV should recognize the signal though, and treat it as such....

overscan is gone with UHD samsung should really fix this.

try in the nvidia driver display -> adjust desktop colour settings -> content type reported to display.

if they follow specs and you have something like graphic, desktop programs, games or similar you maybe able to beat it but you are most likely wasting your time.

In PC mode with a frequency of 23, 24, 25, 50 Hz will be overscan. With frequencies 29, 30, 59, 60 the image will be fit to screen.

Is this older firmware available online? Can the TV be downgraded?

obviously it can, but they won't tell us how.

But don't sweat it, the 60hz works mode works fine. perfect cadence is over-rated.

For future reference, Roku platform tvs are the BEST behaved for monitor use. everything just works, and they don't have any crazy image processing stuff that destabilizes the display response..

My samsung doesn't even support 444 in 23/24hz mode. but on my $200 roku tv no problem,
