I've Started a Spread Sheet listing Confirmed and speculated working models as well as confirmed non-working models. you can view the spreadsheet here:
https://docs.google.com/spreadsheets/d/1HfY6nwoDXw9qPSlJycNuzhJRumG9Adbb2GCb9MV6R3o/edit?usp=sharing
if you know of a working model post up pictures with the full model number in this thread and I will add it to the spreadsheet.
Original Thread:
-------------------------------------------
So Last night I was helping a friend fix a Golden Tee with a bad monitor (necked tube ). he was going on about how he was able to hook up his Dell LCD to test it but he wanted to put a Westinghouse in there to replace the CRT but the Westinghouse wouldn't show an image.
I though this GT board was VGA for sure since there's no way a 15K output would work on an LCD... but I measured the frequency on the sync pin and sure enough it was 25K...
I started doing some research and apparently there are some LCDs that do actually support 25K, mostly older Dells and Vewsonics with a few other brands.
I found a small thread on this on KLOV: http://forums.arcade-museum.com/archive/index.php/t-112911.html
From that these are some confirmed models (listed at the end of this post)
Someone in that thread is also claiming he has an LCD that can do 15K through the VGA port with a sync splitter but provided no other model information.
Obviously even if these work in place of CRTs there are other potential issues such as lag and aspect ratio, HOWEVER having an LCD that works with medium resolution would be fantastic for bench-testing... This also means that in games like Daytona USA and Virtual On that support Spectator Monitors could be used with an LCD natively instead of using the crappy Gonbes converter.
I've got a CraftyMech TPG that does Medium resolution and supports H/V separated sync so I'll be building a VGA adapter and testing every LCD I own to see what's what.... I'd be interested in starting a list of non-CRT displays that support 25K and 15K resolutions. A lot of these display actually list the horizontal sync range in the product specs so that could help narrow down where to look as well.
Known compatible displays so far:
Dell E207wfp (displays permanent error message)
ViewSonic VX2433wm (no error message)
Synaps MB24WKH (no error message)
Dell P2414Hb
