I have a 53" projection

Your Hitachi 51UWX20B is an HDTV-Ready TV. No Digital Tuner. HDTV-Ready means that your TV set is capable of displaying analog and high-definition digital pictures, but without a digital tuner, it cannot receive the digital signal. An HDTV-Ready requires an external high-definition TV receiver (digital tuner) in order to receive HDTV signals. These external receivers can be called an HDTV Tuner, set-top-box, decoder or DTV Converter Box . So you will be required to purchase a converter box to receive over the air programming from an external antenna.

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

No. You need a converter Box the change the HD format (ATSC) back down to standard broadcast (NTSC) for your TV to see signal.

Hi,

You need converter box.

Thanks.

Direct from the Hitachi website - "Integrated HDTV Tuners: Hitachi's new top-of-the-line XWX series features built-in ATSC terrestrial and cable HDTV tuners to provide integrated high resolution, high-definition signal decoding." You will need a seperate HDTV tuner if you do not have cable or satellite and want to watch off-air High Definition channels.

yes i have same tv it has no digital tuner >( you must get a converter box

If you have a cable box, it may be set up for the full aspect. I just got a hd box for my 53" Hitachi and also notice the aspect dose not change using the remote. The guy installing the box was pushing so many buttons during set up I have no idea how to change without calling them. Hope this helps.

You Dont need one your set is HD. So when the switch happens you are good to go. The only TVs that are going to need converter boxes is those who do not have HD or only have antenna.

HDTV-Ready - Requires separate receiver to view HDTV signals.

You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.
