Even many TVs with appropriate inputs will not scale the output of old game consoles properly.
Old game consoles used non-standard hacks to get 240-line progressive video out of a 480-line interlaced display. Many newer TVs will incorrectly interpret these "240p" signals as 480i signals and attempt to deinterlace them. This not only results in terrible picture quality but also introduces a ton of lag. You need a proper upscaler to correct this.
