Re: [CAD_CAM_EDM_DRO] Dos v3.3 video resolution

Hi Jon,
I purchased a Milltronics cnc lathe recently with a bad monitor. I thought I
would simply replace it with a 12" lcd I had laying around, it fit perfectly
in the original hole. The problem is with the current resolution. I only
have about 6" of viewing area in the middle of the screen. I can see the
everything fine, it's just very small. I would like to utilize the rest of
the screen. The Trident card is capable of 800x600 resolution (according to
the web). I just don't know enough about MS-Dos to put two and two together
to make it work. Or maybe it is an impossibility for Dos and the Milltronics
software to accomplish this.
Any help is appreciated!
