VGA/SVGA resolution in DOS

HP DreamColor Z24x G2
FreeDOS

Hello,

I am picking a 16:10/1920x1200 IPS LCD for work in AutoCAD, photo editing and for my hobby old DOS games and this one looks like best to me. Could you tell me please what exact resolution does use this LCD when I run games under DOS in these resolutions 320x200, 320x240, 640x480 and 800x600 from VGA or DVI output to LCD's DVI or HDMI inputs?

 

According to my experiences every LCD (tried always native 1600x1200) behaves differently. Some use the resolution 1280x1204 (blurry picture) for all those resolutions and some use stretched 700x240 for 320x200/320x240 😞

 

The best looking picture (interplolation) should be a multiple of the exact height and the result must a number without a decimal point. For example 320x200 (200*6=1200), 320x240 (240*5=1200), 800x600 (600*2=1200) and I get a 4:3 aspect ratio picture with 2 vertical bars on both sides. The output resolution 1280x860 should be for 640x480. That is why I picked this LCD.

Or it is possible to choose directly from a menu of this LCD some of these supporting resolutions below?

 

920 × 1200 @ 60 Hz
Preset VESA Graphic Modes (noninterlaced)
640 × 480 @ 60Hz
800 × 600 @ 60 Hz
1024 × 768 @ 60 Hz
1280 × 720 @ 60 Hz
1280 × 960 @ 60 Hz
1280 × 1024 @ 60 Hz
1440 × 900 @ 60 Hz
1600 × 1200 @ 60 Hz
1680 × 1050 @ 60 Hz
1920 ×1080 @ 60 Hz
1920 × 1200 @ 60 Hz

 

I hope that I described it well.

Thank you very much.
