Title: GM in 31Khz
Post by: bimm25e on August 14, 2017, 09:44:52 am
So I have seen a few posts on the matter but I want to confirm before jumping off a cliff
(http://forum.arcadecontrols.com/index.php/topic,130820.0.html (http://forum.arcadecontrols.com/index.php/topic,130820.0.html))


I am currently using a Neotec NT-35C (Standard Res, 39" :D )  monitor in a cab that I have setup for GroovyMame.

I have the opportunity to do a monitor swap to a Neotec NT-3602 (VGA Resolution, 39" :D ), and a cabinet upgrade to Gauntlet legends Dark legacy.   I love the idea of GLDL playing nice with a full resolution-ed screen, but I don't want to sacrifice those tasty CRTEmudriver/GroovyMAME resolutions.


Are there users on here with 31Khz only monitors, (the NT3601 even :D) who use Groovymame in 31KHZ mode, how does it look?  anyone have a resource for video or pictures of a screen with a game up on it?

So far Google seems to be telling me i'm looking for something a little too specific for it today.

Thanks for the help gang!

Your question is how do 15-kHz games look on a 31-kHz display?

Well, sure I guess so


I don't want to use true 15KHz modes as the monitor has a far better picture in 31KHz with fake scanlines than it does in low resolution, and I'm not comfortable having it switch between syncs regularly.

If you're not going to use real native 15KHz resolutions, then why even use GroovyMAME?

I don't know, does groovymame not do anything forb31 khz monitors? Does a 31 khz monitor just naturally look good ?

Cools is talking there about a multi-sync unit, as you'll know. Multi-sync arcade monitors quite often provide a not-too clean picture at 31 kHz, which indeed benefits a picture with simulated scanlines effect/black-frame insertion. Though, in my experience (which is not much with these, actually), it's not better than the actual 15-kHz display.

It much depends on one's preferences, as well as the monitor's behaviour. For instance, some people are crazy about high-end 15-kHz BVM displays with over 600 TVL, in which case a good VGA monitor at 640 x 480 with simulated scanlines effect (or black-frame insertion, since it'll support 120 Hz) will show a very similar result. I myself find that too unnatural. I'd say if you're used to old arcade monitors, keep a true 15-kHz display at hand. 39'' 480-P is not something I'd reject, though; there are many things to emulate/play at that res.

Man after my own heart! My thoughts exactly. :)
