Trying to create monitor presets for KT-2914 (Betson-Kortek) MultiSync
8BitMonk:
Bump. Any further advice on troubleshooting Calamity?
Thanks!
8BitMonk:
I was able to figure out the process through trial and error and going back and carefully re-reading all of Calamities instructions and commentary in the thread.
Below is version 1 of my presets for the Betson. It works great for nearly all of the games on my test list (see google spreadsheet). They run at perfect speed and look fantastic. I have to tweak the porches and/or create a new subrange for Paperboy as it's an odd one, I believe it uses range6. Diehard stutters a bit but I'm pretty sure it's not the modeline, it's the emulation, it's a 3d game. The range0 games (mvsc, neogeo, goldnaxe, robotron, shinobi) still have a little more black space around them than I'd like, need to tweak the porches a bit more on them. Even though the border in Arcade_OSD is right up the edge with my current porch settings it still comes up a bit short all around for those games and some range1 games.

Delusional and RetroACTIVE let me know if you do any more testing and find games with issues and I will continue to test and tweak.
Thanks!
RetroACTIVE:
I've got to reinstall my system, had a major crash and burn. I am thrilled you guys kept this going... it's a challenge for sure! Maybe if I'm lucky I can get back up and running this week and get into this again.

Below is version 2 of my presets for the Betson. This fixes all of the games on my original testing spreadsheet including games like Paperboy, 720, Sprint and 240x240 games like Burger Time. The preset isn't complete yet but covers the most common games, I've tested a lot more games and they all look and play better than they ever have on my cab, it's amazing. I was able to get rid of most of the black border with games that fall into range0 like neogeo games and Marvel vs. Capcom. The remaining space is due more to the aspect ratio of the original games, they are supposed to be a little more rectangular. Mortal Kombat fills the entire screen now.

OTHER NOTES:
The Betson OSD settings are per horizontal refresh rate. Maybe this is common knowledge and something all arcade monitors do but something I didn't know. I assumed the OSD adjustments were one universal set. Anyway, when you adjust the OSD on the Betson the settings are particular to that horizontal refresh rate only. This is very important for getting your monitor dialed in. The best way to adjust is outlined in the steps below:
* Run a game from the command line with a log file (ie. groovymame64.exe -v mk > mk.txt)
* Look in the log write down the modeline values. The modeline is near the bottom, the one that says updating, like this: Switchres: updating DALDTMCRTBCD2560x256x0x60 - Modeline "2560x256_6015.65KHz 54.71Hz" 52.07 2560 2664 2912 3328 256 262 265 286 -hsync -vsync.
* Write the values in bold (above) down on a sheet of paper.
* Open ArcadeOSD and go to the resolution used in the modeline, ie. above it was 2560x256, and select it.
* Go to edit modeline and turn off the locking on the vertical.match the values for the dot clock and horizontal and .
* Change the rest of the values to match the numbers from the modeline, starts with the dot clock then 2560, they go in order from top to bottom.
* Hit the number 1 key to see the changes applied
* Lock the vertical refresh rate
* Hit esc to go back a menu, you will see the 'save' line has turned red. Select it and hit return to save.
* Now using the Betson OSD adjust the image so there’s no bowing, it’s near the edge etc.
* You need to do this for each range used.
About vector games.
I’m not using Groovymame for vector games, I plan on running a vanilla version of mame with HLSL turned on for vector games.
Strange pacman adjustment.
For some reason with pacman even though the screen adjustment looked perfect in ArcadeOSD I was getting a weird ripple effect going through the screen. I tried various adjustment in the preset values, turning on frame delay and vsync etc. but nothing seemed to work. Finally I played with the Betson OSD and found that if I shifted the image to the left slightly (setting of 72) or less it goes away. Not sure if it’s just my monitor or all Betsons, I haven’t noticed anything like it in any other game. The fix is easy though and the slight left offset isn’t noticeable.
After doing this the games look friggin amazing, better than they ever have on my monitor, and play silky smooth. I couldn't be happier with the results.
Happy testing, hope this helps some other Betson owners out there.
Calamity:
Hi 8BitMonk,
Sorry for my lack of feedback these days, I'm in the process of house moving. Hopefully by next week things will be back to normal.
I'm impressed again with how well you have figured out the whole process by yourself, congratulations.
I have my doubts however that this preset will achieve the same exact results with another Betson monitor. For this model, it seems that as you have explained the particular adjustment of the monitor itself plays an important role on the resulting picture.
For instance your crt_range0 has much more reasonable horizontal porches than our previous one. For some reason RetroACTIVE's monitor needed huge porches for that range in order to get he picture properly sized.
Your statement that this monitor has memory presets for different hfreq ranges and reacts accordingly also makes much more sense than our previous belief that it was the vertical frequency the critical factor. I had never quite digested that idea, but it's difficult to figure out the actual behaviour from the distance.
