The Sinclair QL Forum

Part 2 of the other question.

What do you use for video display with your ORIGINAL QL? Not emulators, not Aurora. Original QL.

LED TV 22" with 4/3 display, RGB and HDMI input.

But I upscale all in FULL HD (RGB to HDMI) so the QL works in FULL HD.

That is the best solution for me

I'm using a rather unusual setup: a PC with TV card as video input and VLC player to display the QL's screen on the PC. This has advantages (using one monitor for both PC and QL without having to switch), but also disadvantages (low quality picture since I have to use the composite video). Since I use emulators for most of the time now I don't consider this a big problem. Nevertheless I would be very interested in a QL to HDMI adapter so I could finally enjoy the full 4 or 8 QL colours to the max .
One question though - does the monitor have to support 576p/50Hz TV mode for this (which most monitors don't) or does it upscale to standard PC resolutions as well?
*EDIT*: 576p should of course be 576i.

Does the card in your PC have a S-video or RGB input?

S-Video (which I know consists of separate chroma and luma signals). I still have to figure out how to generate these two from the QL output, which only has pins for luma (which works fine in monochrome) and composite (which gives a lot of noise). Any ideas?

Ummm, uhhh, nooooOOOOoooo? *shifty eyes*

I use an upscaling converter from SCART (RGB) input to HDMI full HD output with a clear and nice vision of entire QL screen

I do very much the same and enjoy a nice, crisp, full-resolution QL picture. IMHO, that is the best, cleanest and most modern way to get video output from a QL onto a modern screen. In case your HDMI screen has USB ports (mine has), you can even power the HDMI upscaler from there and have a self-contained system.

What system do you use? I've got this board:

which results in a pretty jittery image and this thing

which produces a rock stable picture but with the first two characters missing on the left side

I considered building my own upscaler using an FPGA board buf if there is already something that works...

What tofro uses, and I also own, looks exactly like the SCART-HDMI converter in your link.
But with my QLs, the picture only appears shortly from time to time. Even with identical SCART cable wiring.

So I also had to resort to the GBS RGB-VGA converter. Not very sharp output, and it takes a minute to "heat up" before the picture gets stable.
