Got the monitor, done some very quick testing in portrait mode, colour and contrast doesnt change, viewing angles are great too, the only thing is the screen is quite reflective but once playing a game you don't notice, think we have a goer
very easy to decase as well, just pulls apart -
with no layouts in mame and the correct aspect ratio there is indeed top and bottom letter boxing.
installed pinball vs arcade, screen res is 1280x800 as the pc i may use is a little underpowered, more on that later
screenshot was thru mame then i resized it to 800x1280, doesnt look too bad for aspect ratio, will have a play around later this weekend perhaps with the settings.
