I just received my Mcable Gaming Edition today and I plugged it in my PS1+OSSC setup to test it out… I have a lot of interferences with the resolution settled on Lx4 that is the mode I’m used to use with this console.
With Lx2 mode the interferences doesn’t appear at all but the game looks blurry… in Lx4 it looks like the photo I attached… Something I can do?
I think you are talking about this settings right?
Lx4 PAL (1080p50) (Generic 4:3 mode)
1. Increase H. Samplerate to 2200 and H. Active to 1920.
2. Decrease V.Active to 270.
3. Increase V.Backporch until you get picture (approximately 28).
NOTE: TV needs to be able to force to 4:3 aspect ratio.
If aspect ratio still looks off, try H.Samplerate 2460, with both H.Sync and H.Backporch around 215. Source
Alternatively, if you cannot force 4:3 you can attempt a Lx4 1440×1080 50Hz 4:3 image: increase H.Samplerate to 1900, H.Active to 1440, h.sync 150, h.backporc 212.
