Since when is high res a bad thing? There is no question in my mind... Okay I'll tell you my sad sad story, I like to call it Woes of an Arcade Monitor. I was a newb. I was so ignorant, I could just plug the JPac into my relativly new arcade machine (1996 Run and Gun 2) and I would be done. I plugged everything in, but only like 50 games worked on its super low crappy resolution.
A good arcade monitor is expensive too, you also need to mess with things like an isolating transformer; and don't forget the death charge you need to release from the tube

too many times was I electrocuted to even think of doing this again! I thaught once would be enough, but I got a nasty shock from my iso trans when I was taking it out. Okay so maybe I wasn't shocked, but I could have been.
For the love of God don't make the same mistake I did. If this is your first cab use a PC monitor.
Oh, Casto I challenge you to tell the difference between a pic of my screen with an arcade monitor and with a PC monitor. Give me a day or 2 to find the pics.

There is no difference. Unless you are a arcade perfectionist (the knid of person who dosn't use an IPac because they think it is too slow) In which case you SHOULD have an arcade monitorm otherwise there iis no reason.
