This is the example:

;GRAPHICS Example

; Set The Graphic Mode
Graphics 800,600

; Now print something on the graphic screen
Text 0,0, "This is some text printed on the graphic screen (and a white box)!  Press ESC ..."

; Now for a box
Rect 100,100,200,200,1

While Not KeyHit(1)
Wend

Which doesnt work really, it doesnt show the text nor the rectangle,but this works:

;GRAPHICS Example

; Set The Graphic Mode
Graphics 800,600,32,2

; Now print something on the graphic screen
Text 0,0, "This is some text printed on the graphic screen (and a white box)!  Press ESC ..."

; Now for a box
Rect 100,100,200,200,1

While Not KeyHit(1)
Wend

Why I don't get it?

Kaisuo,

What John was alluding to, is that you need a "SetBuffer BackBuffer()" statement after setting the resolution.

Every time you want to see the updated graphics, you need use the "FLIP" command.

Graphics 800,600,32,2
SetBuffer BackBuffer()

....draw stuff on the screen
Flip ;make it visible

WaitKey()

End
