It would be nice if this was built into more TVs/projectors.
i used to have an old CRT that would display up to 16channels at once(it cycled through them though, so only like 1frame/sec).
seems like cable companies have killed the need for pip type displays. i still have PIP on a few of my tv's, but for the love of me i can't figure out a reasonable way to use them, haha.
maybe when we completely ditch cable, and everything is streaming over the internet we'll get easy to use multichannel viewing again. i mean there's no reason i couldn't open up 4 youtube channels on my HTPC and have them play simultaneously.
