MVS and CPS3 are 264-line systems (most “240p” sources are 262 or 263 lines), so their 2x-multiplied output is 528 lines which is not within +-1 lines around nominal 525 which is the tolerance for some TVs.
THX for your help. I try it and unfortanelly dont work with my SONY HDTV. It’s definitely dont compatible with exotic resolution.
So I succes to play with my MVS and CPS3 + OSSC with 4k HDTV of my brother but sometimes sound cut/jump. Do you know how to fix it please?
