resolution fails

Hay,

trying to use the resolution 1024 x 768 on my 19" screen and all I get from ET is a nice shutdown with an error. I putted my pc resolution already to a 4:3 resolution. These are the settings.

seta r_mode "-1" unsafe
seta r_customheight "768"
seta r_customwidth "1024"
seta r_customaspect "1"


maybe you need the bits thingies aswell ?

seta r_depthbits "24" unsafe
seta r_stencilbits "0" unsafe
seta r_stereo "0" unsafe
seta r_colorbits "16" unsafe
seta r_texturebits "0" unsafe



Tnx in advance
