Re: [Thinkpad] 560z 128mb RAM Chip

Well, you won't need one if the drivers on your laptops were set up properly.
Besides, what do you mean by "to no avail"? Be a bit more specific here. My vanilla
P133 tp560 switches resolution perfectly from 800x600@16bpp to 640x480@24bpp in 3
mouse clicks.

What I meant was, are there any utilities out on the "web" (perhaps free ware) that
one might use to change resolutions? For example, most video card or video chip set
mfg.'s offer specific utilities to change resolutions on their hardware without
having to rely on the o/s to do it. Does anyone know of a general video utility that
can manipulate video?

In the case of 560 "lcd", I agree, it's just not physically possible to get a 12.1
800x600 to do 1024x768 despite the video card or chip set. My question was general,
do anyone know of a utility that can manipulate resolution without having to use the
o/s to do it ?
