I regularly play my PS3 on a 37" SDTV and many games look great on it. Infact the entire CoD series looks better on that SD Tv then on my HD tv. The SDTV also has much better colours then all but the most expensive HD TV's i see at stores. But many games i find unplayable on that SDTV, GT5, and certain levels of uncharted2 are down right ugly in comparison.
