Title: Betson Imperial / Kortek KT-2914 27" Multisync Monitor squashed on right side
Post by: ehauk on March 04, 2014, 10:51:27 am
At 800x600 everything looks good, but when a game launches using a lower resolution (soft15khz) the right side of the appears squashed on the monitor. It is not a problem with the game since I can view it from a remote session and it is being rendered correctly. A round circle on the left side of the screen will appear as a vertical oval on the right side. I have not been able to alter this using the monitor adjustment controls. Hopefully I'm just missing something and I don't have a bad monitor.

I can't say much about soft 15k because I've never used it but are you definitely running the game at a resolution that the monitor and soft15k will handle?

2914F or 2914DF?  All the 2914DF models do this.  It's a design flaw.  They just slapped a "dynaflat" CRT on a deflection stage not designed for it - surprise, it looks weird.

The 2914F exhibits it to some degree, too, but you can often fudge things into looking reasonable at a cost of making other things slightly out of whack.  There's a "H.LIN" setting (horizontal linearity) in service mode that can be of some use.  You can also play around with pinbalance, pincushion, etc. to fudge the rest of the screen and make the right side look better.

The true fix is to change the value of one of the S-correction caps, but I don't know that anybody ever figured out the "proper" value, and getting it wrong can roast other parts.

I have one of these monitors with the same problem.  As do a lot of other people: http://forum.arcadecontrols.com/index.php/topic,84370.0.html (http://forum.arcadecontrols.com/index.php/topic,84370.0.html).  I mounted it vertically and learned to ignore the issue.  I cannot figure out any adjustments to fix the problem.
