VGA had 70 Hz refresh. So if a monitor, like some LCD ones, does not support 70 Hz then we'll get an image distortion or incorrect games' speed (sometimes may to crash).
What is needed. IPS monitor, 1920x1200 (less preferably 1920x1080) with 70 Hz support on digital port (DVI, HDMI, DP). Good if it has 1600x1200 mode. It's not obligate to support 320x200, as DOSBox will be used mostly. Monitors supporting refreshes higher than 70 Hz, but not exact 70 Hz are interesting too as should to have less weird distortion.
Some LCD monitors may claim to support 70 Hz, but just convert 70->60 Hz and hence an image gets distortion. To check the presence of distortion you may by Epic Pinball Shareware. How to check possible slowdown to 6/7 of game's speed I don't know.
If someone knows models of IPS monitors with specs above, name them please.
