Thanks for the suggestion of the P1917S, I don't think I need pictures, I sort of know what to expect.
I agree regarding CRTs, I do have a CRT, however the purpose of the LCD is to retain easy and convenient access to the output
of my vintage PCs without lugging the CRT around. Hopefully doing it without too many compromises.
For me the 70Hz and 75Hz low res DOS resolution outputs are paramount, and not just accepting the signal and displaying 60Hz while dropping frames.
Aspect ratio control is important, although I don't care if the actual panel is 16:9 or 16:10 instead of 4:3. OSSC may help here.
I dug up some more cheapies in my country, these ones from MSI:
PRO MP253 - Looks good comes with vga - IPS
MP251 - IPS - comes with VGA port
MD271P, MD271P, MD271QP all look good for dos modes
MP2412 looks good, HDMI and Displayport only though and a VA panel
My work has some of those MSI models, so I may take my vintage PC in to test.
