Nanao ms-2931 - Monitor_Specs issue

(1/4) > >>

Hey guys/gals,

I'm just wondering if anyone is using a nanao ms-2931  multi-sync (15,24,31) with groovymame, and if so, what did you set for your monitor_specs? I realize that I can use the cga and vga settings, but if possible, I'd love to be able to take advantage of all of the monitor's features.

Calamity, or anyone else for that fact, could you possibly help me come up with the proper monitor_spec settings for this particular monitor?

Cheers!  :cheers:

Calamity:
You may try with the D9800 settings by now, it may more or less work.

If you wan't to get the perfect specs for your monitor you'll need its manual, hopefully they provide a full "timing chart" to get the values from there.

BTW that reminds me I still have to work out the specs for Banacek's monitor.

I'd like to find the time to write a brief document on how to make those monitor specs lines out of a monitor timing chart.

(I think I'll edit topic subjects about specific monitor models so they're more informative).

I've actually been trying to set up an nanao ms2931 myself lately.

This is the only thing I've been able to find on the monitor.

Given that information, I've been using these lines:

monitor_specs_0 = "15450.00-16050.00, 55-65, 3.91, 6.85, 6.85, 0.190, 0.191, 1.018, 0, 0, 288, 448"
monitor_specs_1 = "23900.00-24900.00, 55-65, 2.91, 3.00, 4.44, 0.451, 0.164, 1.048, 0, 0, 480, 768"
monitor_specs_1 = "31000.00-32000.00, 55-65, 1.09, 3.83, 2.19, 0.318, 0.064, 1.048, 0, 0, 576, 768"

Ive been messing with the porch values, can't seem to get them right, but all the res's made by vmmaker are usable.

Anything you see out of place with those settings Calamity?

thefooz:
Thanks for the replies, guys!

Pyrojoe, I was just about to post that same picture for calamity to see if he could maybe help us figure out the details. Great job on the current spec info. At least that will make groovymame playable on the monitor. From what it looks like, without further info from nanao, the rest, like porch settings and such will be trial and error.

Calamity:
That's great pyrojoe!

I'd definitely would change this value to something like 4.7 for this line:

monitor_specs_0 = "15450.00-16050.00, 55-65, 3.91, 4.70, 6.85, 0.190, 0.191, 1.018, 0, 0, 288, 448"

You can use Arcade_OSD to dynamically find your porch values.
