Title: List of Regular LCD's that can sync or display 15khz for those Troublesome times
Post by: P.H.U. on February 15, 2018, 08:26:07 pm
From time to time, I get a build that for whatever reason doesn't cooperate and I am buried behind a black screen because somehow resolution is not set to 640x480 or whatever. Rebooting doesn't help. I find that an old Samsung Synchmaster 204B can display a 15khz image. Although, just barely but it allows me to make the adjustments I need to get the display back to a visible/workable resolution. Helped me out a TON in jams.

Aside from specialized CGA capable LCD's for commerical use or modern arcades, any of you guys find other such LCD's that can display a 15khz CGA image? Might be of use for others if there is a running list. Thanks!

LCD Monitors that can Display 15khz:
Code: [Select]
Samsung SynchMaster 204B - barely/flickers alot
Dell UM22H - lots of flicker

I have a 1080p IPS  Dell UM22H that will display 480i, with flicker to boot. I'll double-check that model number and test some 240p as well :) I didn't buy it for this reason, discovered the feature by accident one day, but it really comes in handy when updating and testing my cabs.

EDIT: the model number of mine is a dell u2312hm-t

Oh, I have these Dells and know they can't display 15khz resolutions at all:  2001FP & 2007FP. I have had to re-install Windows a few times because of these things.

Having a monitor that can, even if just barely, display 15khz and computer resolutions are god-send some times.

Most* LCD TVs with a VGA input can display a 15KHz signal. LCD monitors tend to be more hit and miss.

*In my experience.

Interesting.

In my experience, with cab builds, it is pretty cumbersome already to hook a PC up to an arcade monitor. In some cases, it is not feasible at all to remove the arcade monitor to put it on a work bench. I am working on a 33" Dynamo right now for instance. Smaller computer monitors are more suitable for this purpose. But Good call on this.
