[SOLVED] HD Video Converter SCART/HDMI to HDMI 720p/1080p problems

The reason for the different indication is that the pin used for sync in RGB applications is really intended as the composite video input, and the converter is displaying the format of the signal it detects on that pin. Due to the way the PlayStation hardware is designed, a retail console can only generate a fully correct video signal for whatever video encoding it was designed to produce. With your PSone, the result is that it always generates a PAL standard 4.43MHz color sub-carrier even when it 60Hz mode.

So when running with PAL software, the resulting output format is:

50Hz frame rate, PAL encoding, 4.43MHz color sub-carrier <- this is a standard PAL signal and the converter will display PAL

When running NTSC software, there are two possible results (depending on the solder blob):
60Hz frame rate, PAL encoding, 4.43MHz color sub-carrier <- This is PAL60, which you get with the blob
60Hz frame rate, NTSC encoding, 4.43MHz color sub-carrier <- This is NTSC4.43, which you get without the blob

If it was a real NTSC console, then it would generate
60Hz frame rate, NTSC encoding, 3.58MHz color sub-carrier <- Standard NTSC signal, but a PAL unit can't do this

Finally, the reason that the sync-on-luma cable shows "NTSC" is that it doesn't contain any color information at all, so all the converter has to go on is the frame rate - and it will display "PAL" for 50Hz and "NTSC" for 60Hz, since that's the only information it has in a black and white signal.

 

My conclusion about this little device:
- it feels sturdy, good build I may say;
- recognize all the signals that I've connected to it;
- support 100% RGB signals;
- the image quality it's OK from my point of view, nothing fancy like Open Source Scan Converter or Micomsoft Framemeister XRGB-Mini;
- no interference on audio and video (if you use a quality built SCART);
- support pass-through/stripper or how do you call it; you can record gameplay from the PlayStation 3, no more blank image like the active HDMI splitters I have tested.

For someone who is at the beginning of the streaming journey it's a good device.
I give this device almost 7/10 for what it does and what it costs.
My only complain about this adapter is the power plug that is near the SCART socket; for the official RGB PlayStation 1 cable - was a nightmare to connect it to the SCART because of the power plug; they could have put the SCART in flipped position so that the SCART cable could not touch the power cable.

All the credits go to @TriMesh for helping me out understanding how it works.

For the rest that are complaining about this adapter, maybe you have a defective one; as @TriMesh said the PCB layout is almost the same for those adapters; he offers some easy tests and you can use them to see if you have a defective one.
