Hello everyone !
I couldn’t find any information regarding support of PC-98 signal and conversion for TV.
When I connect my PC-98 to the OSSC, the signal seems to be recognize, but neither my TV nor my DVDO Edge is recognizing the signal.
Do you have any clue ?
Thank you !November 8, 2017 at 9:42 PM #16968
What’s the OSSC say on it’s LCD and what does the Edge say in the info screen?
Have you tried pressing the safe mode button on the Edge? I know that’s not a proper solution but it can give us some clues.November 9, 2017 at 3:13 PM #16996
I found this picture on internet. My OSSC display the same stats.
Edge display : not recognize signal.November 9, 2017 at 5:41 PM #16999
Hmm that’s pretty wildly out of spec. Do you know what resolution PC98 is supposed to output at?November 9, 2017 at 11:22 PM #17012
It is 640×400 and 24.8kHzNovember 9, 2017 at 11:44 PM #17013paulb_nlParticipant
When you press Info on the remote what does the OSSC say after Vmod: ? Does it work when you set 384p or 480p proc to Line2x?November 11, 2017 at 12:42 AM #17037
It says :
Vmod : 640×384
LO : 880 VSM : 0November 11, 2017 at 2:07 PM #17057marqsParticipant
Optimal PC-98 settings are listed on Optimal Timings wikipage. Note that your display should support 640×400 (or 1280×800) at 56.4Hz. I doubt many TVs accept that refresh rate, so I’d recommend trying a PC monitor instead.November 11, 2017 at 2:37 PM #17062
Thank you for the timing page. I will try it !
My PC screen is already displaying PC-98 without problem. But I would like to try on my TV.
And also curious to see if OSSC has the ability to convert PC-98 signal !November 11, 2017 at 11:01 PM #17087
OSSC can only line double/triple/etc it can’t do any more sophisticated conversion.November 22, 2017 at 12:56 PM #17412
OK, I tried the timings. I can confirm it can pass through both my OSSC and my Edge after timing setup. But the TV is rejecting it. Then I will keep playing on my PC screen. Too bad !November 22, 2017 at 2:49 PM #17417
You could try turning off the output frame lock on your Edge, but be prepared to put up with stuttery scrolling if you do that.
