A IPS panel may be the best match for your setup (but with a higher price tag), or you go with a good (read: with a high viewing angle) TN panel.
(NB: Both techniques are of the TFT-LCD family. An LCD can be backlit by LED or by flourescent lamps. The latter are the bulkier and heavier flat-screens.)
Regarding the slower reaction time of the IPS in contrast to TN: I guess this can be neglected for retro games, which were developed when TVs with 50/60Hz were to be found in a household.
Maybe you can lend a TFT with IPS panel or know someone with an Apple device (Retina display) to evaluate the IPS capabilities, or can view the different panels in a consumer electronics store before making a buying decision.
One more thing: Depending how "noisy" your place is in terms of other bluetooth / wireless signals it may be advisable to use a dedicated USB-Bluetooth and/or USB-Wireless dongle, but this can be changed even once your arcade is built.
@iandaemon Not exactly. An arcade cocktail table and I installed dual monitors in them with a Raspberry Pi 4. My plan B is to use a VGA or HDMI splitter but I'd like to see if can be done with the dual HDMI outputs already available on the Raspberry Pi 4. Any ideas?
@morell From other listings on the site, I found the following:
WBE (wide body extended): Assembled size: 627 x 481 x 635mm (Width x Depth x Height)
U-WBE (ultra wbe): Assembled size: 687 x 481 x 635mm (Width x Depth x Height)
But you could always email the guy to verify what the actual numbers are. (use the 'contact' option in the top left)
You could also (probably) even ask if he would be able to supply the artwork in dimensions of your choosing. He is pretty flexible when it comes to custom stuff, so just send him a message to inquire first. It's always worth a shot, right?
@dontarrestme I don't know what the other emulators use off the top of my head but N64 uses 320x240 resolution by default. If you use the -highres plugins it makes the screen look a lot sharper. I only play my games on my 46 inch TV and it looks fine to me for how large the image is stretched compared to old crt TV's
@delirium_cordia RetroPie (and the Raspberry PI and other SBCs) are all about tinkering and learning new things. No need to rush things if you're not in a hurry - ask away in the forums if you cannot find the answer in the Docs.
Mostly not at 4:3 or 5:4, as I said, because they haven't been manufactured in bulk in almost a decade. It is actively hard to find a brand new 4:3 or 5:4 LCD panel. 99% of new monitors are 16:9 or 16:10.
