Author Topic: Getting the right refresh rate on multisync LCD screen (Read 7792 times)

eldiau · « **on:** April 04, 2014, 04:38:57 pm »

Hi all,
I have a Samsung Syncmaster 214T LCD monitor that supports a vertical refresh range from 56 to 75 Hz, I'm trying to use this monitor with linux and groovymame 0152ex1 .015 to get the right refresh to play games at the right speed.

To my understanding I should use "monitor lcd" and "lcd_range 56.00-75.00" options but I can't get groovymame to switch refresh rate.

I launch groovymame with this command line:

Code: [Select]

rm -f .groovymame/cfg/*; ./bin/groovymame64_0152ex1.015 -inipath .groovymame -verbose rtype
with this mame.ini:

emu@arcade:~$ xrandr --output VGA1 --mode "1600x1200_56.00"

Any suggestions?

Hi eldiau,

Your setup looks right. However the question is what video card you're using. In my experience, and in the Linux context, an ATI card would output our custom modeline/refresh regardless what the monitor EDID dictates. Intel cards on the other hand seem to ignore custom refresh rates for LCD screens.

Hi Calamity,
thanks for you answer

And an Intel card I have!
You probably nailed the problem... I'll try with an ATI card and report back...

No luck

With a PCI-E ATI Radeon HD5450 I get the exact same problem (no sync switching) and exact same log:

Should I try to connect the monitor with the DVI port (I'm using VGA now)?

The verbose outputs says "SwitchRes: -resolution was set at command line or in .ini file as 1600x1200@60" is this normal?

Checking the grovymame .diff at line 2654 I see:

Code: [Select]

if (!strcmp(cs->monitor, "lcd"))than, inside the IF:

Code: [Select]

current.refresh = 60;and

Code: [Select]

sprintf(resolution, "%dx%d@%d", current.width, current.height, current.refresh);
Is this supposed to lock the resolution for the info screens only?

Calamity · « **Reply #4 on:** April 06, 2014, 02:28:23 pm »

No, that doesn't lock the refresh rate, that's only to make sure we get the most likely current resolution for the desktop.

As you see, the commands GM is running are these:

SwitchRes: Running 'xrandr --newmode "1600x1200_56.00" 146.89 1600 1704 1856 2112 1200 1202 1205 1242 -hsync +vsync'
SwitchRes: Running 'xrandr --addmode VGA-0 "1600x1200_56.00"'

You may try those commands by yourself to see if the driver is actually accepting that mode or it is conflicting with its EDID preset.

Also, try using any of the "vesa" presets in GroovyMAME. I know those are not what you want, but they may help figuring out things. For instance, try "vesa_1024".

eldiau · « **Reply #5 on:** April 06, 2014, 04:53:51 pm »

I'm sure the modes get added by groovymame, I can list them via ssh while GM is running and it deletes them after exiting.
I did try launching:

Code: [Select]

emu@arcade:~$ xrandr --newmode "1600x1200_56.00" 146.89 1600 1704 1856 2112 1200 1202 1205 1242   -hsync +vsync
emu@arcade:~$ xrandr --addmode VGA1 "1600x1200_56.00"
emu@arcade:~$ xrandr --output VGA1 --mode "1600x1200_56.00"

on both the Intel and ATI gfx boards ad I get the correct refresh rate so I'm sure they work.
If I manualy set the resolution and after that I launch GM it keeps the resolution, here it's the switchres log after launching xrand by hand and than GM:

Just to add more informations, GM does add the mode to the list but it simply doesn't switch to it.
Here is the output of xrandr launched while GM is running rtype:

Code: [Select]

emu@cab:~$ xrandr

   640x480        75.0     72.8     66.7     60.0  
   720x400        70.1  
   1600x1200_56.00   56.0  
VGA-0 disconnected (normal left inverted right x axis y axis)

1600x1200_56.00 is in the list but non activated

For now I "solved"

the problem writing a quick a dirty wrapper script, it basically run GM for 1 second, capture the xrandr commands, parse them, and use them with the addition of the "--output" command to really switch resolution before running GM again with the correct resolution already switched:

Code: [Select]

Although you call it quick and dirty I think it is a very clever solution you came up with.

Thanks to this I think I now know what's going on. GM switches resolutions by using the SDL "resize" function IIRC. So first it calculates the modeline, adds it through xrandr, then switches to it with the "resize" function. Unlike in Windows, where we destroy the full D3D interface and recreate it, this is not necessary in Linux because SDL internally switches resolutions when asked for a resize while in full screen mode. The problem is, as you may have guessed, that when dealing with LCD monitors, this "resize" is not an actual resize! We're just changing the refresh rate. So probably the mode switch is not triggered. In the CRT realm it's much more unusual to see this case where we only need to switch the refresh rate. Maybe the solution is to force switching to the new mode via xrandr inside the code.

eldiau · « **Reply #8 on:** April 09, 2014, 04:27:09 pm »

Thanks for looking into it Calamity!

I added the appropriate xrandr call to add_custom_video_mode() recompiled GM.. .and it works

, I couldn't add it to switchres_resolution_change() because I miss a couple of variables in there and I'm not into GM code enough. I didn't test it on a 15khz monitor (I'm recapping mine just now) nor on windows (I don't have a windows machine at home)...

The diff is attached to this message...

Calamity · « **Reply #9 on:** April 09, 2014, 04:54:47 pm »

Hi eldiau,

This is great! I'll add your fix to the new release. And that is the exact place to put the xrandr call because switchres_resolution_change() indirectly ends in add_custom_video_mode() too.

BTW is video really smooth at 56 Hz? I mean is actually the Samsung outputting 56 Hz?

At first I was optimistic, I mean, the name of the monitor is syncMASTER after all! I did my testing with rtype (horizontal scrolling), donpachi (for vertical scrolling) a btime (for older games) and despite some tearing they seemed ok, the monitor OSD said the refresh rate was the right one for the game.
But after trying with wboy I realized the monitor is really working at 60Hz and using doing an internal frame rate conversion bringing up really ugly motion artifacts

I also run variable refresh rate on my LCD system but with a fixed resolution.
One LCD monitor displays correct (No ugly tears etc), The other (A HP monitor) does not.

When I was experimenting with GroovyMame/Arcade I could never get it to switch refresh rates with a fixed resolution.
I take it this fixes that problem, But just for curiosities sake - Can you explain what was it doing before and what this fix now does?

Ansa89 · « **Reply #16 on:** April 19, 2014, 05:58:34 am »

Before the modeline was generated, then added, but not switched to (it was mame itself to pick the best modeline from those available in the system).
This leaded to wrong behavior when the new modeline has the same resolution as the modeline in use, but different frequency: in this particular case mame didn't change modeline, keeping the one with wrong frequency.

Now the modeline is generated, then added and immediately switched to.

ozfalcon · « **Reply #17 on:** April 19, 2014, 09:45:29 pm »

OK, Got it. Thanks Ansa.

For fixed resolution operation,
My first attempt at getting dynamic refresh rate was in a similar fashion - And failed just the same :-)
ie. I created/added a new mode then called Mame with -resolution options hoping switchres would select my
new mode based on the -resolution passed. But as it was already at the same res, It didn't change the mode.

Now I create/add/activate the new mode and disable switchres when I run Mame (No resolution options passed).

This leaded to wrong behavior when the new modeline has the same resolution as the modeline in use, but different frequency: in this particular case mame didn't change modeline, keeping the one with wrong frequency.

Now the modeline is generated, then added and immediately switched to.

Just a heads up!!!

I thought I'd do some quick tests on my uptodate Arch system.....

Seems something has changed. I can now create and switch resolutions freely while in X.
Possibly some sort of function like the SDL patch has been incorporated in the video system.

Perhaps the SDL patch is no longer required.

I'm going to noodle around with it today, I'll post any extra info to this thread.

More info uncovered!

My min resolution reported by xrandr is now 8x8 where previously is was 320x240 for the OS intel video drivers.

So perhaps also the video driver patch is no longer required...

The possibilities of this could be:

1. The xorg.conf file is not needed at all, The default desktop (menu) mode can be created from .xinitrc
2. GroovyMame can be run from custom/personal Arch Linux installs without any patches (for operation).
3. You don't have to patch the OS, So it's easier to make newer uptodate builds of GroovyArcade.

It's been awhile since I looked at GroovyArcade, So I'm not sure GA (with sdl patch) needed xorg.conf anyway.

Some other observations:

On my system, occasionally there is some sort of bootup initialization issue which effects:
1. X takes about 30 seconds to start up instead of the usual 2~3 seconds.
2. The system hangs when you try to shut it down or reboot it.

I'm not sure if it's a quirk with my rig or Arch Linux that is causing the occasional fault.
Just something to be aware of.

Nice. Not needing to patch things makes life a heck of a lot easier. Wonder who commuted those changes.

I gather that you still need to place it somewhere, anyway it's good to know.

Yes, it can run fine for the most part but that's not entirely true.

The need to path SDL comes from the fact that some games switch resolutions several times. SDL caches the mode table on its initialization so it can't switch to a mode that's been created after the start a MAME session. A typical test case is ga2. If you use an LCD you may not notice this.

Then you have the video drivers, without specific patches they usually won't go any lower than 320x240. But there's also an issue related to DPMS in current ATI drivers that prevents v-sync from working during a few seconds after a mode change.

Regarding the kernel itself, paching is required if you want 15 kHz outside X. I think you can achieve this by different means but this one is rather effort-less.

You need to patch the kernel too if you want to use an AVGA 3000, it won't work properly otherwise. It seems this is no longer required with the AVGA 5000.

Though still, The situation has changed/improved.
Previously standard Mame would not run correctly in sync mode if the res was created after X was started. And now it does.

The video drivers now report a min res of 8x8 - But they still may not go below 320x240 as you mention.
That's a shame about games like ga2 and the other issues.

The kernel patch is still required for bootup 15k, But it's more an option than a requirement - which is good.
