I got a 720p TV to display 1080p

Yeah, I don't know how.

I have an Emerson LC320EM8A. Its maximum resolution is 1366x768. I have it connected to my Yamaha RX-V467 receiver via HDMI. The receiver outputs sound to a quadraphonic speaker setup. The receiver is connected to my reference 6950 via HDMI.

Somehow I've managed to get it to display 1080p. I set my computer to duplicate displays, set on my Asus monitor's native res of 1080p. Then I turn on the receiver. Then I turn on the TV. Bam. Picture shows up in 1080p without resizing my main monitor.

The picture is jittery and the colors are off. I think there's some scaling algorithm struggling for its life somewhere in this mess. But it is receiving a 1080p input and displaying it. Weird.

That's pretty cool! But i think it would dmg the tv if run long term? < - if that makes sense lol....

I have a Samsung SyncMaster 906bw that will display 1080p (native is 1440x900) but it pops up a warning that says, this display isn't suited to play 1920x1080 and this resolution may hurt the monitor or something... like that.

It has nothing to do with the "upscalling-feature" of some A/V receivers, has it?

I dunno. Maybe? It doesn't work if I turn the TV, then the receiver on. Then it forces my main display to 720p.

I got my 42" 720P to do the same through hdmi. Only a few 1080p resolutions actually display correctly, and it gets a little fuzzy.

I've noticed that my TV (1680 x 1050) can have 1080p forced on it when using HDMI

It doesn't work over VGA or DVI.

Looks awful though tongue.gif

Both my 720P sets will do 1080P on HDMI. One is a Sony Bravia the other a Samsung. The Sony adverts this capability on the box using HDMI. Only problem is, they both are natively 720P so anything above that looks abit Meh. I believe they scale up to 1080P.

Maximum resolution is determined by the number of pixels in the panel (and possibly firmware in some cases, but unlikely). The number of pixels in a panel is set at the hardware level and can't be changed without changing the panel. So it's probably trying to display a 1080p image with only 720p worth of pixels which could cause distortions.

I don't see the benefit of installing a panel with 1080p worth of pixels and setting the maximum resolution to 720p (1080p panels are more expensive). So it's not likely that the panel has 1080p worth of pixels. Which would mean it can never display true 1080p.
