3x and 5x video issues.

[SabreAZ]

Hello, new OSSC 1.6 owner here. I own a Vizio M70-D3 2016 70in 4k tv. Currently i have tested a SNES via Scart, and a top loader NES using the very outdated play choice 10 rgb mod comverted to component. It uses an old Game-Tech.us amp board.

Both consoles work absolutely fine with zero issues in 2x. 1x and 4x flatout don’t work as the tv doesn’t even sense any type of signal. 3x and 5x does give me a video signal, but it’s all out of whack glitchy mess. I imagine this may have to do with sync timings and what not?

When using 3x, and cycling through the various modes, eventually the video will work 100% in generic 4:3 and generic 16:9. But it is random luck. I have to keep cylcing through the settings over and over til it finally works. When it does work, it works. But the second i turn the console off, or change the input, i have to go through this cycle again, it sucks.

With 5x, i expect the same, since it gives me the same glitchy mess as 3x. But no matter how much i cycle through the 5x modes, it never budges.

I assume that this tv clearly can take these modes, but i am not sure what to tweak at all. Again, it has the EXACT same behavior on the scart SNES and the component NES.

Here is an image of what it looks like in 3x and 5x. The game image is not animating either. It just captures the current 1-2 frames when it initially reads the video signal and stutters back n forth between the 2 frames.

Any help as to what I can try to get these modes to work, would be fantastic.

Have you tried anything other than NES and SNES in these modes?

Have you tried the advanced timing tweaks outlined in the “Tips & Tweaks: Lx3, Lx4, Lx5 modes” thread? I suggest you try those first.

Yeah i tried those options on top of reading the entire thread. No luck. Turns out, it has something to do with the HDMI 5 port of the tv, as the modes work without fail on the other ports (port 5 is for low lag gaming).
