Gamecube with OSSC

[haloharry]

Hello, I have been having a few strange problem with the OSSC.
when I play games on my gamecube, at 50hz my tv says am playing games at 576i but the OSSC says it is 625i
but when I play games at 60hz my TV says it is at 480i but the OSSC says it is at 525i

I also get another problem with the ossc which is a LOT worse. when I try 480P this is where ossc starts to play up, I get not picture at all, but when I try x2 mode the picture pops up for a second or two, but at 576p I have non of this it works Fine.

I also do not have this problem when I plug the component cables into my tv.
To play in progressive scan I use swiss as I own pal games.

Is there some setting I can use to fix this problem, or dose ossc not like 480p games???

Regarding the OSSC showing a higher resolution than being output, basically there are more lines being sent out than output to a display which are reserved for data such as closed captioning. Games consoles don’t use these but still output the same expanded resolution.

There’s a note somewhere in the 240p test suite that explains this way better than I do.

625i for 576i and 525i for 480i is completely normal and expected. The console actually sends 625 lines in PAL mode and 525 lines in NTSC mode, as @Paulson explained.

As for the issue with 480p you’re having, it looks like some sort of a sync issue. Does the OSSC itself lose sync or is it actually your television that is acting up? OSSC has a red LED that turns on whenever it loses sync. The LCD also should indicate if the OSSC has lost sync.

Okey, there was no sync error the light was green, but the in x1 mode there is no picture at ALl, but in 2x mode the picute popes up now and then,
but when the picture pop few sec i was able to take this picture. https://drive.google.com/open?id=0B_9ZDjgrYDD3T1pFSWRLR3ZNTVE
looks like the sync is not syncing correctly.

What does the info on OSSC say when you feed it 480p?

[haloharry]

Av2 YPBPR 524p 31.25kHz 59.63Hz

This is gamecube running 480p at 60hz with the component cable.

[megari]

59.63 Hz is quite far out of spec, given that the NTSC standard is 59.94 Hz. Is your console a region modded PAL unit? Those can have funky video timings in 60 Hz mode.

[haloharry]

Mm my TV supports it fine, but the ossc dose not is there a way to fix the gc timing or fix ossc and yes, mine is pal with a xeno chip.

[megari]

@haloharry, but didn’t you say in a post above that the OSSC does not lose sync? This really looks like a TV problem in that it rejects the same timing on the HDMI input it accepts on the component input. Or is there something I have misunderstood about the issue?

[megari]

Of course, it is possible that there is something wrong with the OSSC, but on the surface this looks like a compatibility issue with the TV. Have you tried with another TV/monitor? Can you try with another OSSC unit?

[haloharry]

My TV had a component input I used that for my gamecube before I had the ossc I’ve never had a problem.

I do have two ossc, I just tested 2nd one with gamecube and it works With 480p at 60hz and it is also displaying at 525p 31.46kHz 59.94hz

it is a disappointment that my ossc is broken, but OO well good thing i have a 2nd one.

And thank you all for who help me.

[megari]

OK, then it indeed sounds that your OSSC is probably defective (unless there is some difference in settings between the units that causes this). Sorry to learn that it ended up being a defective unit 🙁

[haloharry]

Am just happy it was the ossc not my TV 😉 my TV is brand new cost a bit.

Try a full reset of the OSSC settings, that’s fixed some stuff for me in the past!
