GroovyMame and Vision Pro LCD
jrose78:
I am in the US. I am willing to accept some issues with LCD for the trade off of convenience. I just want to minimize as much as possible the problems with LCD and these old games.

Is there something else I am missing? Will most of the games still be ok? My other options are hp lp2065 or the NEC MultiSync LCD2090UXI , but they all use the same panel. I just started this cocktail project and already I am stuck on the LCD :banghead:.

Yes by 'custom' I mean anything that's not in the range of 60 Hz, which involves a vast amount of games in MAME. You can still force things to run 60 Hz to get smooth animation but for some games that's too much, i.e. donpachi will run at 104% etc. There will always be a range, rather than an exact refresh value, where things will work fluently, the wider this range the better the monitor for MAME.
Those monitor specs you pasted are input values. The fact that a monitor accepts 56 Hz as input doesn't always mean that the panel is actually refreshed at 56 Hz. What we're interested in is 'output' ranges and these are never advertised. You need to feed the thing with custom refresh rates and sit in front of it to judge scroll smoothness, that's all we can do I'm afraid.
The panel should not be a problem, it's the circuitry in the chasis what makes a difference. In my experience, ancient LCDs proved to be better showing a wide range of refresh rates than my recent ones.
jrose78:
Thanks for the explanation. That explains a lot. I know in MK you could tell on the first screen where it scrolls and on the Vision Pro it was smooth as butter with powerstrip on. I guess its just a wait and see with the Dell although I think the Dell you mentioned is really the same one except wide screen. There are still the other Screens I mentioned if the Dell is a problem (NEC, HP). To bad there wasn't some master list. If anyone is looking to build a cocktail table and running mame it would seem they would want a s-ips with custom refresh and nobody knows which one has those properties for certain.

I got the Dell 2007fp in and it is the s-ips version. The angles are awesome with no real fading like before. Perfect from up, down, left, right. Looks great and no ghosting from my initial test. The bad news is that Powerstrip doesn't really like it and if I launch Groovymame with it enabled it freezes and the monitor goes into power save mode. So I guess custom refresh is out. If anyone on this board has the hp LP2065 it would be cool if you could let us know if Groovymame with powerstrip enabled give you custom refresh. That monitor is dirt cheap and also s-ips.

Just to make sure, did you try this line?
