We said earlier that arcade monitors were originally based on TV designs. So why can you just use a TV and plug into the TV-Out connector on a VGA card?
can BUT you will not get an arcade-real picture. If you use a TV-out what you are actually doing is letting the VGA card re-sample the picture into a fixed TV resolution of 525 or 625 lines interlaced, then encoding into the NTSC or PAL colour standard, then pumping it out into the TV which decodes it back again into RGB and displays at this fixed resolution. This gives a picture that could not be further removed from an arcade game screen! There is no chance of ever displaying any game at it’s native resolution. Everything runs at 525 lines and you need hardware stretching to get the game screen the right size. Definitely not advisable. But there is one way we can use a TV very satisfactorily, which is going in via the RGB pins on a SCART connector (US readers look away at this point, SCART is a European standard!). This actually turns the TV into an arcade monitor because it by-passes all the signal-degrading PAL or NTSC decoder, We can even run native resolutions providing the TV is
