What's the correct aspect ratio I should be using as a config for a HAPP / VISION PRO 19" LCD arcade monitor for MAME Horizontal / Vertical games

What's the correct aspect ratio I should be using as a config for a HAPP / VISION PRO 19" LCD arcade monitor for MAME Horizontal / Vertical games !?

I just flipped it properly so It's displaying in the correct orientation for vertical games, but it's not maximizing the screen for MAME games. Also when running HORIZONTAL games they are creating a windowed letter box both on the top and sides. Specifically for my monitor what are the settings / aspect ratio I should be using to fill the screen both for Horizontal & Vertical ?

This is the model number - 49-2604-30N

Also using Libretro MAME 2003 / 0.78

Thanks in advance !!

@romstar it's not easy to parse what you're describing without photos of the issue. are you physically rotating for vertical games, and returning the monitor to 'normal' for horizontal games? please provide some photos so we can understand.

@romstar

This is a pretty good guide to all the MAME core commands and other stuff that you can do with MAME. Just keep opening the trees and see what's in them

https://dreamauthentics.com/support/mame-guide.pdf

Did you just rotate the screen, or did you use the "rotate" option in your MAME command? Look under "command line" options, then open "core rotation options".

these options aren't exposed in the libretro cores typically used in retropie. that's not to say there aren't equivalents, but i need a better idea of the OP's problem to suggest whihc.

So it's doing this :
https://i.ibb.co/jfBgckT/crunchy1.jpg

here is my rom specific config as of now for :

video_allow_rotate = "true"
video_rotation = "1"
video_aspect_ratio_auto = "true"

Here's my retroarch config:

@romstar your config is non default and impossible to diagnose. looks like you saved over the retropie provided one?

TATE mode for 2003 is explained here https://retropie.org.uk/docs/lr-mame2003/#tate-mode - i believe this is what you want.

[Romstar]

@dankcushions I just looked at that , and don't understand it at all. where do I need to edit in order for the video to fill the screen ?> what config file do I need to manually edit, I can use ssh. I don't need to use retropi menus to do so, I can manually edit the config file(s) I just need to know what to modify...

Here's an example I just did this to the game specific arkanoid rom config file( It now fills the top / bottom but is squeezing the image in the center) I just need to know what the correct parameters I need to enter in order to display the proper aspect ratio :

video_allow_rotate = "true"
video_rotation = "1"
aspect_ratio_index = "19"
video_aspect_ratio_auto = "false"
video_aspect_ratio = "1.33"

@romstar what does your emulationstation screen look like? You don't typically need to set these ratios manually. I use the same monitor as well.

I do recall having to disable over scan to fit the screen image.....remove the black boarder that is.
/boot/config.txt then remove the "#" from disable_overscan=0

[Romstar]

@mahoneyt944

my boot config text looked like this for that section:

#uncomment this if your display has a black border of unused pixels visible
#and your display can output without overscan
#disable_overscan=1

It won't allow me to make changes to it saying permission denied.

@romstar Seriously, just turn on Tate mode as detailed in the post. Open up your game, hit select+X (hotkey+x), go into the quick menu there and find Tate mode. Enable it. It's that simple. Your game will fill the screen.

Hell, you even tried it before... https://retropie.org.uk/forum/post/174446 (That's you...)

Basically, stop trying to edit the config file. Use the menu instead:
https://retropie.org.uk/docs/RetroArch-Core-Options/#setting-core-options

[mahoneyt944]

@thorr69 these are two separate issues.

Tate mode sets the rotation to that of actual hardware. If your only using vertical games then this would work. But horizontal games won't.

editing /boot/config.txt to remove over scan fixes the black boarders for this monitor type.

To edit '/boot/config.txt' you can plug your microsd card into another computer and edit the file. They make many adapters to do this if your computer does not have a slot to do so.

I'd imagine you want everything to display in the same direction though, you might find this useful

@thorr69 I'm a developer for mame2003.

The core is set to rotate the screen image automatically so that vertical and horizontal games display upright on a standard monitor or tv without the need to turn your monitor.

This is not the behavior of an actual arcade machine however, vertical games would have physically mounted the monitor sideways in the cabinet yet the image is still shown normally to the player. So it displays in a 90 degree rotation.

Tate mode is designed for a user that is going to physically rotate their monitor for vertical vs horizontal games everytime. See this video around 3:30

If you are mounting a monitor in the vertical position permanently then you want to rotate the entire system so emulationstation and everything else shows properly. This is done in config.txt rotate_display=1 set the value to 0, 1, 2, 3

Yeah, I know. I've done all of this and have a vertical system. My reply above was an aborted post. I got phone call when I started and must have hit Submit when I meant to Discard. I came back and saw it and tried to delete it, but the time window expired and I could no longer change it.

[mahoneyt944]

@thorr69 no problem, just trying to clear up some of the rotation confusion.

The op needs to remove any aspect ratios they may have altered in their cfgs and set the systems rotation in config.txt then everything should work.

Yeah, this is where I was going, too. I use a rotatable Dell 19" 5:4 monitor, so I manually turn my screen for vertical games. The setup is simple: Use TATE mode as a Core setting and disable Auto-rotate, then set rotations as Game overrides where needed. No other changes were required. The default values worked just fine on every other setting. I've rebuilt it several times and just those two settings are all I have to change to make it work.

[jamrom2]

@dankcushions Understood. I did not know this and was just trying to be helpful. I've been running MAME since 1998 on all 5 of my dedicated MAME cabinets with PC's.

I just assumed they carried over. Sorry.

@mahoneyt944

So first went to ssh to delete any modifications I made. Proceeded to pop in my SD card into my computer and I modified my boot config text as suggested and added "rotate_display=1" did absolutely nothing. The game is oriented in the wrong orientation, and It's to be used for a monitor mounted vertical.

Here is my boot.cfg (scroll to bottom you can see where I added "rotate_display=1":

I don't understand TATE mode I've clicked on the link can someone explain it to me here instead of the wiki ?
