Toranado - I don't know about the framerate or anything, but when I say choppy, I don't mean laggy or whatever... my bf tells me it's called "flicker". I get pretty much zero flicker with gt5, and now it's obvious how much flicker gt4 had - a LOT. I don't know what you mean exactly by "graphical glitches". But to me, everything in gt5 is just more soft in the lines, more rounded, and therefore a little more realistic. (Except for some standard cars where at certain angles I see big blocky problems. Some standard cars are better than others, I think. A few are really really bad!)
My point wasn't to go get a crt monitor. (You probably can't.) I just meant I haven't yet seen an lcd hd monitor with good colour for under $1200. LCD just has problems with colour for some reason. Add in trying to print things correctly, and the problem gets worse.
Though if you're not fussy about colour, you're not going to make any print projects on it, and you're not planning to use it in a darkened room, and you're not going to be too far away from the screen, (or if you're colour blind! lol) this probably won't be a big deal to you. You can probably be very happy with an inexpensive monitor, or a less expensive small hd tv (or even a non hd tv of good quality)
My point was that you shouldn't expect to get a playable game on just any old non hd tv. Some are just better than others.
I have an old (flat screen crt) small non hd tv in a spare room and you couldn't play ANY video game on it at all!! It's BAD. Gt4 is unplayable on it let alone gt5. (I wouldn't like to think about what games would look like on a cheapo lcd non hd tv. eeep.)
That's clearly not true of all non-hd tvs.
So really the question was - is it possible. The answer is not as simple as yes or no. It's input how bad the tv is to tell you how worse it's going to be (comparatively).
If you have a big hdtv all set & already in use, I don't know why you wouldn't use it... except if your spouse doesn't want some big cockpit set up in the family room. hahaha
