Betson Kortek Multisync and using the ArcadeVGA2's DVI out.

[AMDman13]

I know that using the DVI out is only going to output at 31khz + as it is designed for a PC monitor, but the Betson Multisync just plain sucks at 15Khz. The picture looks nice in the center, but there is noticeable squishing of the picture on the far horizontal sides (at least to me)..

So, I got to thinking about using the DVI out from the ArcadeVga2 as it has enhanced and tweaked it's 31khz resolutions to output a more "arcade like" picture. I gave it a try and sure enough the squishing is not a problem anymore.

I ended up reconnecting my 15khz to the monitor because this is a more authentic way to achieve the true games picture, but I'm having second thoughts. I'm just not sure the side squishing is worth it to me.

Has anyone else given this a try? Thoughts or suggestions?

What Betson/Kortek monitor do you have?
The 27inch multisync?

If so, you *do* need to go thru each resolution and adjust it for all the various horizontal/vertical/pincushion/etc settings.

It took me a good hour or 2 to get everything the way I want it.

I *HIGHLY* recommend following this article:
http://www.retroblast.com/reviews/betson.html

Specifically, using the Nokia Monitor Test.
With all of its graphics, it should allow you to set up each resolution to an almost perfect picture.

Yes, I have the 27" Kortek that is in the Retroblast's review. I have gone through each resolution using the Nokia monitor test. This is not a geometric problem. If you run the Nokia test at various resolutions you will notice that the circles in the corners will look more like ovals at certain resolutions running at 15khz and there isn't anything you can do about it. The sides of the screen will be squished no matter what settings you adjust.

I get the squishing on the sides too, but it doesn't sound quite as bad as yours.  It also only seems to happen on some 15KHz resolutions (not all of them).  Is one side worse than the other?  Have you tried the service mode?  What happens if you manually set the resolution at 31Khz without using the DVI connection?  Do you still get the pinching?

Thanks aholfle! Before I bought the Arcadevga2 card I was running the betson with a standard 31.5 vga card and there is no squishing on the sides under 31.5 + modes. It seems to only be a problem on 15khz modes. It's not all of the resolutions, but some of the squishing is worse depending on the games resolution. Again it only seems to be a problem during 15khz.

I have not used the hidden service menu. It used to scare me. Did you ever go back and try any othe the other settings?

Well I only messed around with the 'horizontal linearity' setting in the service mode.  It helped a little but not too much (mine was a little more pinched on the right side, and I was able to minimize it a little bit on that side).  But I was afraid to mess with any of the other settings and none of them seemed to be related to the problem.  I also noticed that if I shift the image over to the left it helps a little at the expense of a slightly non-centered screen.  I've been meaning to mess around with it more, but I just haven't had the time.  If I discover anything I'll post it here.  Let me know if you find a setting that helps.

ahofle, Mine is also worse on the right side but I think I notice it most when running 321x240. I have also noticed it's better if I move the entire screen to the left a little more, but I just beginning to wonder if it's worth it. The arcadevga2 does a pretty sweet job at 31.5. I just hate to give up the 15khz modes entirely because some games  honestly look better this way. I'll keep playing around and will continue to post here. Hopefully some other people will chime in there experiences as well.

I found some things like this to be an issue with golden age games, and maybe a few others - if I was running them with monitor in horizontal orientation. I then went to great trouble messing around with various res's, to no avail. I then set the res to 'auto', and in most cases (Pac, Ms Pac, etc), it worked fine. Still, if I rotated the image, using 'auto' for res, the thing fills up perfectly...and would appear this is the best scenario. TIME TA GET ANOTHA ONE.

Vertical games like Pacman/Ms Pacman do not have this issue.  They look perfect.  It's only SOME horizontal games and it's only at the very edges of the screen (vertical games don't go to the edges of the screen in horizontal orientation). 

marlborroman13, do you not get any pinching on 800x600 modes?

[AMDman13]

It's hard for to say anything about the 800x600 modes as I ran the tri-sync utility, so that res is running at 31.5 + khz. I can't say that I ever tried it at 15khz. I can't think of any games that would require that res unless you are using hwstretch which I avoid anyway. I do agree though all of my vertical games look fine. When ever possible I use one of the few special res's for vertical on a horizontal orientation for these types of games. Although there are some verticals that you just plain have to use hwstretch. For those I use 640x480 -hwstretch.

I have to agree with shorthair. I would love to have a dedicated vert cab, so I could play all of the vertical games at native.
