Nanao ms-2931 - Monitor_Specs issue

<< < (2/4) > >>

pyrojoe:
Yeah, you know, I've been trying to use Arcade_OSD to modify the values, but it seems like if I change the porch values for say 384x224 in the 15khz range I mess up other resolutions in the 15k range.

Should I split the:

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"

Into something like

monitor_specs_0 = "15450.00-15750.00, 55-65, 3.91, 4.70, 6.85, 0.190, 0.191, 1.018, 0, 0, 288, 448"
monitor_specs_1 = "15750.00-16050.00, 55-65, 3.91, 4.70, 6.85, 0.190, 0.191, 1.018, 0, 0, 288, 448"

and adjust the porch values separately?

Calamity:
Yeah if you find that the monitor behaves different for those ranges and it's consistently related to hfreq values then it's a good idea to have independent ranges with different settings.

thefooz:
Pyrojoe, using your monitor_specs, everything seems to work great, except my monitor reverts to 60hz interlaced at 640x480 when it's capable of progressive. Does it do the same for you?

pyrojoe:
Yeah, I've noticed that too.  As I mess with the settings vmmaker seems to switch between finding 640x480 as 15k interlaced and 31k progressive...

I don't really have an answer as to why, though. 

Quick question, how does Donpachi run for you? I'm getting a strange side bar.

thefooz:
I'm still working on getting everything up and running, but I think we're gonna need to tweak your specs a bit. I was trying to run pacman and it was running in a tiny box in the middle of the screen, interlaced, with sound skipping galore. Maybe it's just my settings?

I need to get out of the house for a while. I'll try to check donpachi for you tomorrow morning.

In the meantime, I wonder if calamity has any suggestions for changes to the monitor_specs?
