    While testing my OSSC with my PAL Mega Drive and GameCube, I noticed that the video is a little darkened, not how it’s supposed to be, and not how it appears when I connect the consoles directly to my TV. For example, white appears as kind of a light gray. I can fix this by cranking up the “R/Pr / G/Y / B/Pb gain” values from the default of 26 to the max of 255, but I was wondering if this is normal. I’ve set up a second profile for those two now, but it seems weird to me that two of three of the currently connected consoles have a weirdly darkened image.

    My SNES looks correct with the default values, and the same, whether connected directly or via OSSC. It’s way too bright if I use 255 for it. I tried to take pictures of this issue, but it’s hard to see a difference on photos, even though it’s obvious in person.

    Has anyone had this problem?

    Have you tried changing the black level setting on your tv? The options are usually labeled low/high or limited/full. I know with my setup certain modes with certain consoles forces my tv into pc mode where it handles it correctly and others I need to go in and toggle it or it is too dark. I’m hoping a firmware update that lets you choose on the ossc itself is released someday.

    I’ll take another look at my TV settings tomorrow, though like I said, MD, GC, and SNES display correctly via SCART input on my TV, and the SNES displays correctly via HDMI from the OSSC. Only the MD and GC have darkened images via OSSC, with no changes in the configuration.

    Are you connecting the cables directly to the OSSC without a scart switch? Using a PAL SNES RGB cable on the Gamecube will make it too dark.

    Mystery solved, it’s my cheap SCART switch^^” The color is normal on both the GC and the MD if connected directly to the OSSC. I didn’t suspect the switch because the SNES worked just fine through it, and I didn’t have this issue when the switch was connected to the TV. Thanks, paulb_nl!

    And here I thought I was lucky finding a cheap switch that didn’t have any problems, guess I’ll have to get one of those 150$+ switches after all^^”

    I had these issues with a scart switcher and a cheap scart cable (TV-OSSC)

    Once I bought a decent, heavyweight scart cable, picture was bright and even a little sharper

    Check your scart cable first.

    I recently updated all my cables to new ones from Retro Gaming Cables, which I believe(/hope) should be good enough. The issue also doesn’t appear when connecting directly to the TV, which makes it more likely that the switch is playing a role in it.
