Small Update:
I booted my cyrix 5x86 system into windows and 1600X1200 looked fine running off the Voodoo3, however, Keen 1 & 4 still did'nt display a picture.
I then turned to my P3 700 with a 9800SE running off DVI, booted into dos and hey presto, we had action and keen looked good, Tried prince of persia and it worked, better still, those artifacts(vertical lines) were gone, everything looks nice and smooth.
IMO, Its definately a good idea to run DVI into this monitor, however this would rule out most machines under pentium class, gives me some considering to do, Do I run my old 386 & 5x86 into a brand new old stock 17" CRT and the Newer pentium pro and pentium3 into the 24" DELL?? I think im going to head down that road and do most gaming on the pentium3 and use the older machines for a bit of nostalga/testing or to run the odd game that dont work properly.
