I have received my OSSC 1.6, and I am happy with it! However, I have an issue with Playstation 1, For example, When I play Silent Hill 1, whenever I open the map or go to the inventory, the screen goes black, sound disappears and the OSSC 1.6 blinks red for 3-4 seconds then back to normal, screen comes back again with sound. It is basically like if you’re changing the input of a TV as an example!
I am using a Csync PS1 Scart Cable from retrogamingcables
On a PC Monitor ( Asus ) I have tried all x2 x3 x4 x5, the same thing happens!
I believe Silent Hill is one of those games like Chrono Cross, 480i menu/maps, and 240p gameplay.
OSSC is handling a switch in video signal. So this is actually normal for upscalers, same thing happens with the Framemeister, but I believe Framemeister takes longer to do 240p->480i transitions and back.
The cheap upscaler probably frameconverts every input type to a standard framerate (as well as interpreting 240p input as 480i from the beginning), so the display does not drop image.
3-4 seconds sounds unusually long though, in my experience OSSC resyncs between interlaced and progressive modes should not take more than half a second or so. The main culprit of delay is more likely your screen.
It could be that transitions take less time if you have your 240p mode and 480i mode set to the same output, ie. Lx2 240p to 480p and bob-deinterlace 480i to 480p. However, the framerate still changes slightly so your display will still drop the picture for a moment.
Yeah those cheap upscalers convert to 59.94, this causes stuttering/juddering in motion. Still, you might prefer that to screen blanking, some of those cheap scalers have HDMI input too, so you could try that.
