"VGA Mode Not Supported" Message

[Becker]

Hi,
When i'm trying to test my game or play someone's game, in a mode which isn't Windowed, this awful massage "VGA MODE NOT SUPPORTED" appears on my monitor and I can't play. What's the solution for this problem?
Thanks

What resolution is your game? If it's 320x200, it sounds like your graphics card doesn't support that resolution. In that case, run the game Setup program and use the 2x Filter to run at 640x400 instead.

[Becker]

It doesn't work at 640x400 either 
Isn't there anything I can do with the graphics card to fix this?

Try ticking the "alternative letterbox resolution" option and see if it helps.

Thanks it helped. How can I do this to play another one's game which i'm not testing through AGS?

The (link to the) setup program is called winsetup.exe by default.

It is actually built into the game exe so if winsetup.exe (or similar named) doesn't exist, do this:
Create a shortcut to the game exe, then edit the shortcut (Right mouse click -> Properties) and change "C:\Game\Game.exe" (for example) to "C:\Game\Game.exe" --setup
(Be sure to put --setup outside the quotation marks!)

It opens the setup menu but not the whole one, just the left side of it where there isn't the "alternative letterbox resolution" option .

And what's game name?

[Becker]

And what's game name?

I didn't understand what is your question, can you please explain?

[Scorpiorus]

Sorry, I mean what game did you try this with?
Is it a game made with an old version of AGS?

Ah you see that game was made with a rather old version of AGS (2.30) and it doesn't support changing letterbox mode in the setup.

There is a way to run it with a newer AGS version, but it's not guaranteed to work and should generally be avoided. Let me know if you still want to try that way and I'll elaborate further on how to do this.

But have you tried running it at 1024x768 in fullscreen? You can set it in the setup by choosing 960x600 (most detailed). Yes, it says 960x600 but in fact the game will run at 1024x768 in a letterbox mode, effectively simulating the 960x600 mode.

Or, try to run it in windowed mode.
