So I’m using a Genesis model 1 via RGB SCART to my OSSC v1.6 on v0.81a using FireBrand’s 320 Optimal Timing Settings: http://www.firebrandx.com/OSSC/OSSC%20-%20Sega%20Genesis%20320%20Optimal%20Timing.txt Line 3x is beautiful and seems flawless, I like that line 5x enlarges the image a bit though and would like to use it but the one issue it had is a line about two thirds down the screen that’s forever there it shows up mostly when jumping in games like Sonic but during game boot and tons of other places. Any idea what settings I could tweak to help this? I tried adjusting most of the settings I could think of and nothing seems to fix it. Any help is greatly appreciated.
Edit: Figured it out it was because 5x res was set to 1920×1080 both 1920×1200 and 1600×1200 don’t have the issue on my 4K TV. I’ll just use 1920×1200 as the 1600 stretches it and I don’t like that.
I had the exact same problem as you, and tried switching to 1920 x 1200 and no more screen tearing 🙂 Thank you for posting slickrasta. I also did this when playing SNES as I was getting occasional screen tearing while playing SNES in 1920 x 1080 but playing it in 1920 x 1200 completely fixes the problem. I am a happy man!
