Reply To: Pal Megadrive (modded to NTSC) and Custom MVS(-1A) with TGB cables – Video Noise

[Ivo Fernandes]

Hi Harrumph,

Thanks for your reply.
I followed your tips but unfortunatelty the issue still persists.
Using FirebrandX profiles I get a ton of jitter in the image that only goes away when reverting back to the generic 4:3 option. Changing the phase is not helping I guess.
Yesterday I’ve lowered the brightness of my TV 3 levels to hide the noise and I was pretty much successfull on the MD, but I still see some in the MVS. Today I’ve lowered the gains like you said and I could increase one level of brightness to compensate without increasing the noise. (woo-hoo!)

I hope to test the OSSC with a Saturn in the upcoming days via RGB with an official cable to rule out a OSSC problem and start to think it may be a cabling issue. The RGB for the MD is a regular RGB cable from Retrogamingcables.uk (not the packapunch model)
If the issue goes away with the Saturn, I will invest in new cables.
If someone has more tips, all of them are welcome.
Thanks!
