I have my RetroTink 2X connected to my OSSC. The OSSC seems to think the output is 480i instead of 480p. Is there a setting I’m missing on one of the devices?July 20, 2019 at 11:06 PM #27079
I did more testing and it seems that composite and component come across as 480i to the OSSC, but S-video is 480p. This seems very weird to me. I guess it should be noted I am using the VGA converter sold by Castlemania GamesJuly 21, 2019 at 1:09 AM #27081

This doesn’t make sense to me. If you’re referring to what’s displayed on the OSSC’s screen, that’s describing the input signal, not the output signal; so it’s receiving 480i, and it’ll be up to your TV or other downstream video processor to display what the OSSC’s output resolution is.
In the case of S-Video appearing as 480p, that’s likely the RT2X line-doubling 240p or 480i from S-Video and providing it as 480p to the OSSC.July 21, 2019 at 4:02 AM #27082
The OSSC sees the output from the RetroTink 2X as 480i for both composite and component. Now I think the component 480i was because of the PS2 I was using to test. It didn’t matter though if the RetroTink 2X was in passthrough or 2X mode. Both of them were being received by the OSSC as 480i. I don’t know if this is because i didn’t turn off the OSSC when making the changes to the RT2X.
The OSSC was seeing S-video as 480p input in both 2X and passthough mode on the RT2XJuly 21, 2019 at 6:41 AM #27084
The OSSC will automatically resync when it detects a mode change, so if you switch between, say, 240p and 480i, it’ll pick that up automatically–no need to powercycle it.
The only reason I can think of that the OSSC would be detecting S-Video from the RT2X as 480p is if it’s still line-doubling it. Does the RT2X remember line-doubling modes per-input, and did you toggle the video processing modes on the RT2X with S-Video active?July 22, 2019 at 2:23 AM #27097
The RT2X doesn’t remember modes. It starts at 2X by default. I tested again today with my Gamecube to make sure what I was seeing. I hooked up composite to the RT2X and chained it into the OSSC. In 2X mode, the output was 480p as expected. In passthrough mode, the output was 480i. I know PS2 output is 480i, is that the same for Gamecube? I thought PS2 was the only one outputting in 480iJuly 22, 2019 at 3:58 PM #27109
I believe the PS2, Xbox, and the GameCube normally start up in 480i/576i, and they all require something specific to enable higher video modes (PS2 needs software support and sometimes holding a button on start, GameCube requires something on the digital AV port and a button press, Xbox needs a YPbPr component cable and an NTSC video region configured). I’m only aware of an alternate BIOS for the Xbox that would make it boot in a higher resolution.
Dreamcast is the outlier, in that it will output 480i/576i if you have any kind of video cable connected other than a VGA cable/box; and then, with the VGA cable/box, it only outputs 480p.July 22, 2019 at 7:52 PM #27111
Ok, I see. That makes sense.
