As someone who is as "newbie" as newbie can be within the world of Build Your Own Arcade Cabinet (BYOAC), the "what kind of monitor" issue is one of the most daunting issues (for me) that I am currently contemplating as I am planning out my project. Sure I would like it to be as "authentic" as possible ... but then again, I am thinking I would also like to integrate console emulators as well (not 100% sure of that one just yet). So I continue to read through discussions such as these toward researching and (hopefully) ultimately figuring out what the best overall solution will be.
As an admitted "Child of The 80's" - the MAME (classics) arcade game aspect of my BYOAC project is probably most important to me. Truth be told, I've never really been much of a "gamer" in terms of today's major consoles and games. So many buttons/combinations ... I miss the "good ole' days" of the Atari joystick + button. (go ahead, throw all of the "old geezer" jabs you want at me ... I'm turning 44 YEARS YOUNG on Oct 10 (2013) and I'm still benching 305+ at the gym every week. So

)
I do have a PS3 and a handful of games - but even our 14 y/o daughter doesn't play them much anymore (more interested in being social and boys - ugh) - and our PS3 sees most of it's use as a BlueRay player and access point for NetFlix and, sometimes, YouTube videos. (I know, I know ... Don't hate me for not being as geeky as I should be)
So while the #1 game priority for me are the classic arcade games, there is a part of me who would still like to try to integrate some of the older console systems as well - such as the Atari 2600, ColecoVision, Intellivision, Nintendo, etc. (Okay, I know the games from those days are little more than big ole squares with sound effects . . . but it's a nostalgia thing, ya know?)
I suppose, if need be - so preserve the best visual integrity possible - I could always plan TWO separate cabinet projects ... one for the classic arcade games (and appropriate monitor) and one for the Hyperspin type of array of console emulators. I mean, it would be cool to have a mess of gaming options to play around with ... and for younger visiting relatives and guests form time to time.
So, any constructive thoughts, insight and/or advice for this mixed-up nostalgic newbie BYOC'er?
