Help with CRTEmu Driver and 31khz PC CRT monitor
« on: April 20, 2018, 06:36:24 pm »
I have a sony G520 that supports up to 2048x1536 @ 75hz.
I always tested it with my nvidia 1060 and hdmi to vga adapter and using CVT timmings I was able to get super resolution to work as 3840x240 @ 60hz.

Now, I'm trying to make it work with my Radeon HD6450 using a vga directly into this monitor.
I want to be able to have 2048x1536 desktop and super resolution.

The problem is that when I import the super resolution ini file into VideoModeMaker it changes some resolutions and screws everything up.

This ini file
## Desktop ##

2048 x 1536 @ 75.000000 desktop

## Super resolutions ##

2560 x 240 @ 60.000000 super
2560 x 248 @ 60.000000 super

2560 x 304 @ 60.000000 super
2560 x 320 @ 60.000000 super
2560 x 336 @ 60.000000 super
2560 x 344 @ 60.000000 super
2560 x 352 @ 60.000000 super

2560 x 384 @ 60.000000 super

2560 x 464 @ 60.000000 super
2560 x 480 @ 60.000000 super
2560 x 496 @ 60.000000 super

How can I make CVT timmings and make those work with my monitor while keeping it's original max resolution?

That's probably due to the monitor preset you're using. VMMaker doesn't support CVT but it supports VESA GTF (similar, older).

There are several VESA presets in the monitor preset dropdown menu, pick the one that has the maximum number of lines you want to use, e.g. vesa_800 allows up to 800p resolutions, etc.

You don't to add your desktop resolution to the user's mode list. That's a PC monitor, so that resolution it's already provided by its EDID to Windows, you don't need to override it with a calculated modeline.

Then, you say you previously did 3840x240@60Hz using CVT timings. How was that? Does your monitor support 15 kHz? Was that doublescanned?
Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.
