Did some testing this morning, with good results. I have an LM1881 sync stripper on the RGBS/audio RCA output of my 6-port Otaku scart switch.fernan1234 wrote:On another subject, I'm wondering if anyone has noticed vertical line noise on the video from a source with sync strippers. I was testing a bunch of my consoles with the GBSC today and noticed this kind of noise only from my PS1 and PS2, and I believe the cables I have for those happen to have sync strippers, so I suspect that may be the cause.
The noise is much less noticeable on the 480p and 1080p output (virtually gone on the latter), but 480p looks kinda blurry on my setup at least and 1080p doesn't work well with 240p scanlines, so it is a problem given that it's very noticeable on the 1280x960 output mode which is the one I prefer for cleanest picture and scanlines. Turning on line filter also helps since it adds a bit of blur to the picture. If it turns out to be due to the sync strippers on the cables I'm going to look for some alternatives.
I tested the following:
SNES Mini (the original mini, not the newfangled miniature/HDMI version) w/ RGB mod and dejitter mod, csync
PS1 SPCH-1001 w/ Xstation, luma sync
Sega Genesis Model 2 w/ 3BP, csync
N64 w/ N64RGB, csync
Everything worked flawlessly, with the exception of the SNES. It kept losing syncing, and the image was jumpy. Turning SyncWatcher off fixed it. Whenever power cycling the system, I would have to turn syncwatcher on and back off. Once this was done, it worked flawlessly as well.
Not vertical lines or noise or any other anomalies, just high quality, low-lag scaling on the cheap.
