Trying to create monitor presets for KT-2914 (Betson-Kortek) MultiSync
RetroACTIVE:
Ok... so here is the monitor_specs0 line I configured (which had no effect)...
monitor_specs0 15625-15900, 40-80, 3.090, 4.630, 7.720, 0.648, 0.194, 1.297, 0, 0, 248, 448
This is what I think each of the fields mean... am I right? Question marks mean I don't have a clue what they mean... :)
monitor_specs0 HFreq, VFreq, H-FP, H-SP, H-BP, V-FP, V-SP, V-BP, ?, ?, ?-max x lines, ?-max y lines
Thanks again
Calamity:
- I'm assuming you added the line to mame.ini
- Check there's no duplicated label for monitor_specs0
- Check some log to see that your monitor_specs0 are actually read (or attach it here).
I'll be with your issue today, your latest results really puzzled me...

Yeah... I'm pretty sure I added it and I FORGOT to post the logs... i did see it in there. But... you never know with me ::)
I'll double check this evening.

There are several odd things in your report:
- You said "So here is the modeline as it is selected by the game:" so I understand you copied the full modeline data produced by GM into Arcade_OSD's 256x224@60 video mode and then took the photos. The odd bit is that the modeline shows hfreq = 15.243 even if we limited hfreq by means of monitor_specs0 to a minimum of 15.625, so something is wrong here. It would help if at this point you add the same monitor_specs into vmmaker.ini to recalculate the resolutions and reboot. That will produce modelines that are already closer to the ones calculated by GM.
- Instead of editing the horizontal porches in order to correct horizontal amplitude so the picture fits the screen (as I suggested), you tried the seemingly wrong idea of tweaking the vertical porches instead, but contrary to the logic *it did work*. Considering that horizontal timings among both modes are almost the same, that jump in horizontal geometry can't only be explained if your monitor is somewhat "correcting" the horizontal amplitude by itself based on hfreq.
So, make sure you adjust the right modeline in Arcade_OSD, this should be in the range of 15.6 - 15.7 KHz if the monitor_specs0 line is being considered. Then get the horizontal porches for it. Keeping inside that hfreq range (15.6-15.7) should ensure these porch values will still be valid when used by GM, as it'll be calculating within those ranges. Let the vertical values alone by now (keep the ones we had before: 0.190, 0.191, 1.018).

Ok. I updated VMMaker.ini with monitor_spec entries. I tried to run the VMMaker.exe and its crashing. Please look at my .ini file to see what is wrong.

Sorry about that... this time I adjusted only H settings and got 4.580, 4.580, 7.630
This was enough to correct the image.

There is no modeline within that frequency range at the desired resolution, I suspect the problem will be corrected when I get VMMaker to run.
Again, thanks sooooo much for the help.
