It depends(tm). I think the VT code just does "640x480x4bpp" and lets the BIOS sort it out. A lot of things don't cope well with 640x480 these days - they try autodetecting picture edges, but a black border makes that very difficult. -adrian On 14 January 2017 at 08:57, Matthias Andree <matthias.andree@gmx.de> wrote: > Am 14.01.2017 um 00:11 schrieb Alan Somers: >> I take it back.
