80's games have a lot of black/space backgrounds and neon-like colors, for that I'd think a VA panel is better suited.
VA panels also have less issues with uneven or bleeding backlight (the latter manufacturing flaw is frequent on IPS monitors)
For using simulated scanlines I wouldn't buy anything less than 1080 in vertical resolution, otherwise in many cases there'll be scaling artifacts (uneven scanlines thickness creating ugly patterns)
And, well, in fact note even 1080 is too tight for crt shaders, artifacts happen. 1200 and above is better, there are still a number of 1920x1200 (16:10) monitors available, most of them IPS though I believe.
There's also the question of framerate and fluidity, most of the games you've mentioned clock
above 60Hz (60.05, 60.60) and in our day and age most monitors and TVs will apply framerate conversion to that, meaning you'll experience stutter/hiccups.
There's only two possible fixes:
- force 'sync to monitor refresh' in MAME (games will run at slightly reduced speed, hard to tell the difference)
- use a monitor that's vertical refresh-agnostic in combination with an AMD graphics card, CRT_Emudriver, and GroovyMAME (an unkown pool of +/- decade-old monitors, or many current ViewSonic monitors. in 1200p they only have the
VG2438Sm though, afaik)
WARNING: no 16:10 monitor that I know features justified 16:9 aspect ratio mode for external 16:9 sources. You'll be fine if the source is a computer of course, but no guarantee the picture won't be stretched with a console or arcade board. Oddly some of them feature a 4:3 mode, but it'd be wise to check before buying.
The first solution is of course immensely simpler and satisfying for everyone but accuracy-OCD people. ^^
The second solution is much more complex but opens the gate of accurate clean smooth-everything, almost all games in MAME running perfectly at their real refresh speed (yeah even MK games and such), and it requires one of those old monitors or one of the select compatible ViewSonic that are vertical refresh agnostic (which can be determined in the user manual if you find any mention of 56Hz in the supported modes list)
It's like the results of basic FreeSync or G-Sync setups, but arguably more accurate (those nVidia and AMD variable refresh techs reportedly have a few issues with stuff like 60.05 or so that are the closest to 60)
Now I guess you weren't asking about that but heh, I think the framerate topic was still worth mentioning for the sake of being thorough.
Leaving that aside and going back to finding good 1920x1080 or 1920x1200 monitors, well the former are found everywhere really, in IPS most of the time but there are a few VA too, in 21~22", 23~24", 27" and 32" (avoid the 28"), and the latter 16:10 afaik only exist in IPS now and are also not too hard to find from the usual name brands, though sometimes they're listed as business monitors.
Telling you which models are 'good' is tough, since nobody reviews such low-resolution displays these days, people are all over 4K, and some still WQHD (2560x1440), but no one cares for Full-HD or 16:10 anymore.
I'd get advice from
pcmonitors.info, one of the few websites to still care, they have recommendations and a friendly community forum (they have no knowledge of emulation etc though, but they know what matters for quality monitors, still, be thorough explaining what you seek)
EDIT: *sigh* guys those 'tell me a good lcd' threads are ALL the same no matter the community forums you're at, a guy asks questions sounding serious, people post detailed replies and....OP's gone.
Bet 9/10 times they expect 'yo bro buy that one its the best' but arent ready for the technical stuff if it comes. Too bad, you can't have the best stuff if you don't learn. :p
