It is nice to get the screen filled, still single pixels can not be distinguished in every area. The picture is significantly clearer on my 1024x768 monitor using the "black bar" CPLD workaround. Hard to tell what I'd actually prefer, unless I try. I have been generating 1024x768 @ 60 Hz DVI/HDMI directly from $5 FPGA with only moderate overclocking, maybe that leads to a better Q60 solution one day. At the moment I still struggle with manual BGA soldering. ___ QL-Users Mailing List

Well, everything is relative... You can find a built OSSC with its remote and power supply for 160-180 euros. Given the amount of money I spent in the QL hardware over years (not counting 2 scan converters that never worked properly and costed as much), that's peanuts to keep that costly QL hardware usable in the coming years (and till it dies... or I do). :-D > Is the native resolution of your monitor 1920x1080? I tested it on a 1680x1050 LCD monitor (Hyundai W220D) and on a 1920x1200 one (Eizo FlexScan EV2455). The photos were taken with the W220D (that is likely to get dedicated to the task when my last CRT will die, the other, newer LCD monitor being used with my PCs). In the case of the Q60, the OSSC must be configured to output a 480p HDMI video, but the actual HDMI resolution can be set to either 980x512 or 1960x1024 (via scan doubling on the OSSC side; an equivalent result may be obtained with picture scaling by the monitor, but I prefer to keep my monitors in 1:1 mode, i.e. without scaling at all). The sampling must be increased to 1200 pixels per line and the H/V back-porch and delays must be appropriately adjusted to get the Q60 screen to fit the HDMI frame. > The published Q60 screen appears a little blurred, but that might be a > matter of taking the photo. A close-up would be interesting. The photo I published was probably a tiny bit blurry, but the blur is indeed also the result of a scaling (the lines doubling is not a problem but there are actually 980 pixels per HDMI video line where the Q60 displays 1024). Here are two new photos (full resolution, untouched: 30Mb each !) in DNG format, with and without scan lines doubling: http://qdos.free.fr/images/Q60-1960x1024.dng http://qdos.free.fr/images/Q60-980x512.dng Without scan lines doubling, only a small portion of the screen is used, of course (in 1:1 monitor mode, and scaling at the monitor level gives the same result as with scan lines doubling at OSSC level), but looks almost pixel-perfect (and actually better than on my CRT monitor, which thinks the Q60 video signal is 640x400). Note that the screen looks much nicer when seen with your eyes than on the photos (you won't see the monitor pixels when your eyes at 50cm of the screen, while the camera got them all); for example, the blue strip of the QPAC2 "Things" window looks perfectly smooth when seen with your eyes. Frankly, I'm quite satisfied with the result, even if it won't match what could be done (without the need for a scan converter) with a native 800x600 mode on the Q60... ;-P Thierry. ___ QL-Users Mailing List

Re: [Ql-Users] FGPA Anyone (Mister)
Hi, I can confirm that on my Mister (32MB SDRAM) the new core works as expected without any problem. SMSQ/E loads perfectly . The system is stable like a rock and speed index (Test909) report a speed 13 times of a BBQL (@ full speed), 10 times when Gold Card (24MHZ) selected So, most probably your problem should be with the new 128Mb sdram. fabrizio On 13/01/2020 18:51, Daniel Baum via Ql-Users wrote: Hi Marcel, I'm afraid your core doesn't seem to work on my Mister (or I've messed up somehow).

Re: [Ql-Users] FGPA Anyone (Mister)
I know literally nothing about programming Mister cores, but on the forum they say that you need to update the framework to make cores compatible with 128K SDRAM cards. I hope that means more to you than it does to me... D.

If it nicely converts the Q60 signal, that would be a big point despite the very high price. Is the native resolution of your monitor 1920x1080?

I'm aware of it and it's of course quite a beast, but it's also more expensive and, this might be the camera, monitor or non-optimal settings, but on your QL example I see that you got Moiré effect in the stippled pixels. Anyway, sure, that is a pretty versatile option at least. Marcel ___ QL-Users Mailing List

Hi Marcel, I'm afraid your core doesn't seem to work on my Mister (or I've messed up somehow). I get a black screen with a white Minerva logo in the bottom right corner, which appears to be gradually overwritten with more blackness.
