    I have an old 720p HDTV. The manual
    https://www.manualowl.com/m/Westinghouse/LTV-27W2/Manual/254913
    says it supports 1080i.

    Can I expect it can also display (downsampled) 1080p content?

    I plan to use this Westinghouse LTV-27W2 to display a live security cam feed.

    The TV itself can display input provided at the following resolutions: 480i/p, 720p, and 1080i.

    If you give the TV a 1080p signal as input, the TV itself can't scale it for display. You would need to connect another device capable of scaling the video between the TV and the camera in order to re-size 1080p video to one of the resolutions that the TV can display.

    Thank you very much for your reply, usually_quiet!

    I accept your answer, and that is what the manual says...but it seems odd to me that someone would create a device which downscaled 1080i but not 1080p. In other words, I was thinking it more likely that the manual was wrong instead of the hardware.

    I think I'll find a way to feed it 1080p just to satisfy my amazement.

  4. It may work or not, it may work incorrectly - i have TV where 1080p is supported (not specified) but video is slightly desaturated and have no possibility to control saturation...

    Your TV is 12 years old. In 2005, it wasn't unusual for TVs to have 1080i as their maximum input resolution.

    1080i support was for the highest broadcast resolution used at that time. Blu-Ray and other 1080P content wasn't commercially available.

    My 55" rear projection TV has the same limitations.

    This all totally makes sense, everyone. I didn't buy my first HDTV until 2008, so my imagination failed me. I got stuck thinking that as long as they were processing 1080 lines, they could process than 1080p as well as 1080i. I didn't realize 1080p wasn't available yet, when the old HDTV I got 2nd hand was made.

    New question:

    Is there some kinda (hopefully affordable) box that will output 1080i or 720p when fed 1080p video?

  8. Have you checked to see if the security camera you intend to use can be set to output something besides 1080p?

    Good question...but I want it to output 1080p because I'll be feeding the picture simultaneously to the old HDTV the above AND to a nice, newer 1080p HDTV (on which I want an optimal picture).

    I found these:
    https://www.amazon.com/Revesun-Video-Converter-Scaler-Coaxial/dp/B00P283QKG/
    https://www.amazon.com/Sewell-Upscaler-Downscaler-output-resolution/dp/B01MU32ULM/
    https://www.amazon.com/E-More-Mirror-Scaler-Converter-Separation/dp/B00MWWF2G6/

    Reading reviews, these did not work well for everyone. Pro HDMI scalers that are more likely to do a good job start at around $200.

    New 24-inch 720p TVs that accept 1080p input can be found for $100.

  11. Is this just 1 camera and how does it connect to 1 or more TV's? Direct connection or does it have some kind of box it plugs into first? If the camera goes to it's own control box first, can you set different output levels to each TV, or does it have to be the same for all connected monitors?

    It might be helpful if you could provide details of the make/model of the camera system.

    First, I'm endlessly amazed at what a great forum this is, so full of both expertise and generosity!

    I should have posted here before selecting a camera, because I limited my choice to a camera w/HDMI output (because it's primary destination is the HDMI port of my newer 1080p.HDTV).

    However, to make the 80' run in between I plan to use an HDMI-over-Ethernet-Extender. Given this, here's my new question:

    Instead of limiting my camera choices to the small number w/HDMI output, can I widen my search to the ubiquitous Ethernet security cameras?
    (In other words, would an Ethernet-to-HDMI adapter in the newer 1080p.HDTV's HDMI port be a good solution?)

    (I don't want to use WiFi).

    In case the answer is "no", the camera I chose because it has an HDMI output is an AXIS M3045-V
    https://www.axis.com/us/en/products/axis-m3045-v

    I'm sure usually_quiet is correct, I should simply buy a new HDTV instead of a scaler. (Particularly since, when I tried feeding my lame old 720p HDTV with anything but SD it was a hot mess [it was visible up to 1080i but, as suggested, at 1080p it totally failed]; I think I figured out--sorry everyone--why my relative gave the piece of junk to me!)

    But I'm thinking that at first, I'll simply feed my one current 1080p.HDTV with a new security camera, period. (Hmmm. Perhaps in a few years when I upgrade to a 4K.HDTV, I'll upgrade to a 4K camera too!)

    I'll continue to display the output of the SD security cam I've been using for decades on the lame old 720p HDTV (which it does do AOK), until I save up to afford a new smaller 1080p.HDTV.

    When I do display the new 1080p camera output on multiple HDTVs, I figured I'd use an HDMI splitter.

    An Ethernet to HDMI adapter won't be useful for an IP camera. IP security cameras are meant to be connected via a home network to some kind of network video recorder, or a computer/tablet running compatible software, or maybe a Roku, not directly to a TV, although I guess it's possible some cameras would have a smart TV app available that could "see" the camera stream via the TV's Ethernet connection to your wired home network.

    Thank you very much, usually_quiet!

    (I did a big of googling, and( Apparently there are such aps but on only a few platforms (GoogleTV, FireTV).
    I think I'll stick with the HDMI camera noted above.

  15. You could, recode it to 720p.

    Thank you very much for your reply, VideoGuruDude!

    You mean there's a way to recode it in realtime?

    (I want to watch the security camera source live. And I don't currently own any smart TV device. And, oh, it turns out my old 720p HDTV can't even display 720p acceptably.)

    The only way to do that with the set-up you have described is to buy a video scaler, which you have already decided against.

    Yessir, usually_quiet, I have indeed!

    I'm not just short on funds but also short on time, so I love how dead-simple it will be to go from one Camera w/HDMI output, to a single HDMI input.
