I need to send out a 1080p signal from a 1080p souce via HDMI to two TV's simultaneously. One of the TV's (the primary TV) is 1080p while the secondary TV is 720p. Is there a cheap solution to downres the signal to the secondary TV to 720p (it wont accept a 1080p signal). The second TV is 27" and the viewing distance is generally greater than 10' so any solution that provides even decent quality is good for my purposes. My point here is I dont want to have to settle for 720p on my main display just so I can get 720p on the secondary display. Any help would be appreciated.

Does your source have outputs other than HDMI? If so, and if it will output both simultaneously, then all you need is component, S-vid, or (ick) composite to your 720p set. I doubt that HDMI on a small 720p set from 10' will look any better than S-vid.

Unfortunately, no it wont. It is the PS3. And really, I have seen both HD and SD on the TV and from 10' you can still tell a pretty big difference - at least to the wife and I.

I'm afraid you are probably out of luck. Not much call for simultaneous viewing on two different TV's these days. Out of curiosity, exactly why do you have to view both of these at the same time?

The cheap solution is to send out a 1080i signal to both tv's. You just need an HDMI splitter like from monoprice.com or Gefen.

For only $82.50 each when QTY 50+ purchased - 4X2 True Matrix HDMI 1.3a Powered Switch w/ Remote Controller (Rev. 2.5) | Auto/Powered HDMI Switch

If you want something to downrez the video you are looking at a much more expensive solution. See if you can tell the difference between 1080i and 1080p. The 720p set should accept a 1080i signal no problem and downrez it internally.

I will take a look at the 1080i on the 65" Mits and see what it looks like. I just hate not to use the TV for what I bought it for - 1080p. I am already splitting the signal using a Gefen splitter. I am just growing weary of having to change the resolution upstairs just so i can watch the TV downstairs. Its frustrating to say the least. Actually, so much so that I have now considered getting a 1080p set (or one that can at least accept 1080p) for the downstairs but really really dont wanna spend the money on something like that when its such a small TV.

Feeding a 1080i signal to the 65-inch Mits doesn't mean that the TV isn't displaying 1080p. The TV will take that 1080i input and will internally convert it to 1080p for display. With most content the result will be identical (or nearly so) to what you'd see if you fed 1080p to the TV.

[font="arial, helvetica, sans-serif;"]If you want to fast get a 720p video from a full HD 1080p, you'd better down-convert the 1080p files. In fact, there are lots of benefits for downsize a 1080p video: [/font]

1. Downsize 1080p videos to 720p for smooth playback on your device that can only support 720p

[font="arial, helvetica, sans-serif;"]2.  Compress 1080p large movies to 720p saving space[/font]

[font="arial, helvetica, sans-serif;"]3. If you got some 1080p camcorder footage like 1080p MOV, 1080P AVCHD, 1080p MXF, you can  convert them down to 720p for easy editing with your video editing system.[/font]
