MadVR exlusive mode blackblinking and glitches and washed out color no brightnes

I got help to find out a good solution for less stutter in videoplay. Eve at the forum helped me and showed me how to play madvr in exlusive mode and all that one need to do.  no use of  interpolation (dejudder at zero), only use BFI at medium and also turn off tonemapping. aslo lock madvr to 2160p120/2160p119. turn off displaysetting. so forcing a 5 pulldown with 120hz instead of 23hz sync. He got best result reguarding smoothness and stutter. And it looks acually from what I can see to very very good on my TV too. this could be a very good solution and no annoying artifacts due to interpolation.

But I get blackblinking one after another..but I am able to view a bit of movieplay inbetween, which looks to be very good. I also get glitches every second and the a small pause and then a some seconds with glitches and so on and I also dont get brightness and the colors are washed out.(not like low brightness due to BFI)

He said he can not help me anymore and think this looks superweird.

What could cause this ..the black blinking and washed out colors. He also got an Lg Oled. He a C1 and I a B1.
He says further that this could be a bad gpu and suggest to buy a new one and also reinstall windows. I have some time back during the summer reinstalled windows 3 or 4 times. so I dont think window could be the problem.

Does anybody know what the problem most likely are(black blinking, glitches and washed out colors)? is it most likely gpu? or windows? or both?

My desktop is new: intel i5 12600kf, 16 ddr 4 ram, msi rtx 3050 8 gb gpu, systemdisk is ssd and the moviedisks are regular hdd disk which I have tested for failure(they are all good).

I showed the osd and picture from how tv is behaving through hidden menus... one can see this in the end of my thread here. https://yabb.jriver.com/interact/index.php/topic,132094.150.html#lastPost

I also uninstalled Msi afterburner which I only used to settle the gpu fan.

You still need to follow the troubleshooting steps.

1) fresh windows install (not from the summer)

2) If this still doesn't work, with the amount of different issues you seem to be having, I think it's time to attempt using another 30 series GPU.

It has to be a 30 series (or current gen AMD) to get out of the box 4K 120 4:4:4 over HDMI 2.1. You can use a Club3D adapter to do USB C display OR DisplayPort > HDMI 2.1 120HZ but that's another link in the chain so to speak.

If you're getting washed out colors and major brightness issues playing SDR content, something is VERY amiss.
Work the problem one step at a time. A new install of windows (without ANY software you regularly use except JRiver + madVR) is a good starting position.

Screen blinking on and off can be a symptom of a cable that isn't quite up to snuff as well, especially when you're dealing with the bandwidth requirements imposed by 4K 120hz 4:4:4

Hendrik:
Broken SDR after playing a HDR video is a madVR bug, and nothing we can do about that. You have to restart MC to clear it, typically. We strongly recommend using JRVR. We made it specifically because of such issues.
