Is it possible to use an LCD monitor for a TV?

Q. I would like to purchase a LCD monitor and hook it up to my tivo and some speakers, they are so much cheaper than LCD tvs. Is this possible? Do I need some type of converter? Do LCD monitors all have the same inputs? Help please!

A. It depends on the cable service you got your Tivo hooked up to.

If your cable service is standard-definition (uses coax or composite to connect to a TV), then you can't use a computer monitor.

If you have digital HDTV cable service and the cable box has a DVI or HDMI output, you can use any HDCP-compliant LCD computer monitor to display the HD cable box's video output.

The video signal carried by HDMI is in fact single-link DVI, so a DVI-to-HDMI cable can be used to connect an HDMI cable box to a DVI monitor. And cable boxes ARE TV tuners (which is why they have remotes for changing channels), so the monitor does NOT require a tuner on-board to work with an HD cable box. It merely displays whatever DVI signal the HD cable box is telling it to display.

Since broadcast-quality High Definition TV signals are at least 720p (1280x720 resolution), pretty much any LCD monitor can display 720p, as long as it is HDCP-compliant so it will work with the digital HD cable box.

If you want 1080i broadcast HD, you should get an HDCP-compliant monitor that can display 1920x1080 resolution.

Keep in mind most computer monitors have no speakers. You will have to hook up a separate set of speakers to the cable box to get audio.

Hope this helps.


Does LCD monitor or plasma give more better quality image?
Q. I know LCD monitor is cheaper then plasma but more LCD have 1080p, right? Which is better? Why there is a price difference? I know LCD is liquad, and?

A. Plasma has better response time so will show movement better than an LSD TV; important when watching action particularly sports. A good LCD has a 5 Milli Second response time where as a good plasma 0.2 MS.

LCD screens are generally much brighter and better suited for rooms the receive a lot of light. Plasma's are better in darker rooms; easier on the eyes.

Generally plasmas are 42 inches or larger. LCDs are manufacured by more companies.

LCDs sometimes are manufactured with pixles that are burned out causing a dot on the screen. Plasmas have problems from screen burn.

I decided after much research to forget about buying a set for another year; I was holding out for 42 - 48 inch 1080 p plasma. A couple of weeks ago Tiger Direct had a 42 inch LCD 720 p set on sale for $699 and I couldn't resist. I am extremely happy because I am getting a great picture, I have all the bells and whistles (PIP, split screen, TV tuner, multi connectors including computer) and I paid a lot less than anything I have seen before or after.

My advice: Get a good inexpensive 720 p that you you like (plasma or LCD) make sure it has an antenna (broadcast hi def is better than hi def on cable or satelitte), and enjoy. 1080 p is more expensive and really only gives a better picture with a Blue Ray DVD (also relatively expensive).

By the time prices fall for Blue Ray machines and discs and more channels are broadcasting in hi def the price of TVs will fall dramatically. Move the set you buy now into another room and get yourself a bigger set
