Trying to create monitor presets for KT-2914 (Betson-Kortek) MultiSync
AMDman13:
Last night, I decided to take the plunge and start 8bit's latest calibration. I'm a bit of a perfectionist and I struggled to make the 800x600 screen look perfect.

What type of calibration tool did you use? A simple grid?
Thanks for all the work you have put into this. I plan to follow your lead

Hey AMD,
I use the EIZO free monitor test utility or there's another free one just called Monitor tester. The old Nokia one is still around too but it doesn't work with Win 7 64. You won't get things perfect by any means, these monitors are notorious for having a little bending in the corners. Give yourself a little room around the edges.
Make sure you're using the Wells presets, In your last post you mentioned using my presets from this thread and I have abandoned those. I don't think the porches etc. differ enough from the Wells to be worth messing with and the problems were mostly due to not understanding how the Betsons group display settings and adjusting accordingly.
After calibrating at 800x600, set the Wells presets in the groovymame Mame.ini file and then with my PDF document launch the games listed on each sheet and adjust the onscreen display. I found the quickest way to do this is straight from the command line because after running a game you can just hit the up arrow and retype another rom name in the prompt, rinse and repeat. Again I'd avoid going all the way up to the edge at first. You're going to find horizontal and vertical games in each category and since they're sharing the display settings over adjusting one game may push another one off screen. It's a bit tedious, may take an hour or more but my list includes most heavy hitters in each category so once adjusted it should be pretty dialed in.
You might want to note the settings you end up with for each group, mine are in the upper right, yours won't necessarily match. I included blank pages to print and use. Knowing what your settings are for each group allows you to reference them. If you come across a game that doesn't look right you can pull up the OSD and look at the values and find what group it falls in, what other games are within it, and how much that might allow you to adjust.
Hope that helps, good luck.

Thanks for the clarification 8Bit. It certainly helps. Okay great I have something called Test Grid and I know I have the Nokia one, so I should be good to go.

So, I need to delete my presets in GroovyMame's .ini and change the Monitor type from "Custom" to D9800?
I am assuming that since I choose the D9800 as the preset within VMmaker that the driver is already optimized for the D9800. Then I should be good to go?
Or, I see you slightly tweaked yours.

Should I leave Monitor Type as Custom and add those?
Thanks for your help! I should have some time tomorrow to get started on this. I will report back. Hopefully not bombard you with too many more questions. :laugh:

Yep, exactly right, I forgot I had lowered a couple so you'll want to adjust the D9800 values and set to Custom.
Another tip is to tape down the little adjuster board to the top of your CP with temporary tape like masking tape or painters tape. It's way easier than having to constantly pick it up and have it falling off the side as you go through and adjust.
Good luck, let me know how it goes.

After much tweaking I went back to using 8bit's old presets. Both the D9800 setting and the minor tweak by 8bit cause lots of what I call "slithering" with vertical games. Its when a portion of the screen sort of twitches. I find using 8bits older presets that this problem is almost completely gone with most vertical games. If I knew more about tweaking the presets I would probably have to customize my own. Seems these monitors are finicky. No two are the same. I will say that going into the defaults and adjusting at 800x600 has helped with the overall geometry.
