    I tried hooking up my N64 and GC (both NTSC) to my RT2X and the picture from both looks like hot garbage. The image is blurry and there is flickering on some of the pixels.

    The RT2X is in passthrough mode and is connected to the OSSC through VGA. On the OSSC , I checked that all line modes are in generic 4:3. I tried the LPF at 9 MHz and Auto but neither made any type of difference. I’ve tried line multiplication 2X and 4X and neither of those helped.

    I would love any help that you guys can provide to help fix this issue.

    Hi bamf226.

    Does it look like “hot garbage” when connecting the RT2x directly to the TV using the miniHDMI to HDMI cable?
    It is no longer recommended to use a VGA adapter with the OSSC but a much better HDMI to Component conversion box.
    For some reason the VGA adapter messes with the pixel uniformity and distorts the image, but not the recommended HDMI->Component box.

    As recommended here:

    Can also be found on ebay for the same price.

    This sounds like you’re using composite video, and that’s, honestly, to be expected with composite video–it sucks.

    If you’re concerned about video quality but not going to go for quality RGB and/or HDMI mods, buy a decent S-Video cable (Message the seller for an appropriate cable if you have a PAL console.); that will greatly improve the picture quality.

    Yes, I was using composite. I will try an S-video cable.

    How much of a difference am I going to see between the HDMI -> component box and the VGA adapter (which was the approved adapter when I bought it last year)? I’ve got so many cables and switches for everything, I’m running out of outlets to plug things in (not to mention an additional cost for the box plus another set of component cables)

    S-video makes a difference, but it doesn’t seem to me that the OSSC provides any real benefit when chained to the RT2X. It often looks better in 2X + smoothing from the RT2X instead of the 2X line multiplier coming through the OSSC. I think the only reason to chain to the OSSC is for 5x mode with the NES.

    I still question if the video is worse because of the VGA converter. If so, how much better would it look with the component box linked above? Would it be worth it to buy the component box or just stick to 2X mode with the RT2X?

    Switching converters to take advantage of the LPFs on AV1 and AV2 might clean up a small amount of interference, but it’ll do nothing for the blurriness or pixel crawl when using composite video; whereas S-Video should have a nice, crisp image with maybe slightly fudged colors.

    Thanks for the info. Looks like I will hold off on the other converter to see how the NES looks. I can use the RT2X exclusively for Gamecube, PS2 and N64
