In fact, I found out today that by increasing the sample rate to 1260 (from
the 1200 I used so far) on the OSSC, I could get it to output a 1024x512
(without scan doubling) or 2048x1024 (with it) resolution in the 480p HDMI
signal format... and the good news is that the monitor accepts it !

Here are the new high resolution pictures I took:

They are almost pixel-perfect. For a comparison between the OSSC+LCD
solution with a CRT 17" monitor, here are a couple more pictures (at a
lower resolution so that you can compare them side by side):

As you can see, the OSSC and LCD monitor perform quite well...

Very interesting, since the best solution would indeed be to gain a
standard resolution output on the Q60.

I never tried that myself... There are a few interesting videos on
Youtube about it, in particular this one:
