To expand what has been said, QB is capable of using it's graphics commands on VGA modes. VGA modes only have 256k (four pages are used to create "chain" mode that is screen 13. Because of this limitation, 640x480x16colors is the highest resolution QB can pull off.

The closest thing to an industry-wide standard for higher modes, is called VESA. It is not well supported anymore, but there are a number of QB libraries such as Future Library and UGL that will let you access this mode. However, it cannot be done with regular QB graphics commands. Modern operating systems controll their systems with industry-made drivers, and standard graphics APIs such as OpenGL or DirectX.

FreeBASIC, however, because it is for Windows, and can therefore access Windows routines with its graphics commands, can use 800x600 at any standard color depth. For instance, in FreeBASIC, 800x600x256c is Screen 19.

No.

It's impossible to tweak QB's SCREEN 12 to a working 800x600 resolution.

As said before, the standard VGA is incapable of running in 800x600 mode - it doesn't have enough memory, and it couldn't be addressed anyway... you have to use SVGA/VESA.

WIDTH is for text output.... Tongue .. so, no...

Here:
http://fbide.sourceforge.net/

If you really want Basic and a 800x600 screen, FreeBasic is always a good option... it can go all the way to 1024x1280... Get the: FBIde 0.4.1 + FB 0.14 Bundle Release.. :wink: ... and, for any help with FreeBasic:

:wink: There ya go...

It can use whatever resolutions your graphics card/monitor enumerate; I just now wrote a simple test that set a 1600x1200 mode. Tongue
