HDMI cables are the best for HD resolutions. Any kind will work fine since they are all digital cables. They either work or they don't :) I get my HDMI cables here. They are inexpensive and quality.

The HDMI doesn't work properly


HI

The resolution is only set by the sending unit, in your case the cable box. You need to change this to at least 720P something the your TV can handle.

Now once you have down this, to try and solve your HDMI problem I suggest you do the following.

Switch-off your cable box and the TV set, unhook the HDMI cable.

Now reinsert it carefully to make sure it connects properly on both sides.

Now first switch on your TV and set the input to Video 6 ( your HDMI channel )

Now wait for 30 secs. Switching on your cable box.

Do not press anything and check if your picture now stays on without shut-down.

if the menu and other startup screens on the cable box is not flickering, but the normal picture you might have a HDMI conflict with your TV set.

O, you cannot change the input types.

Hope this helps!

4yr old Mitsubishi DL 52525, HDMI input vide problem


Are you sure its the TV and not the source? Are you sure its only the HDMI port on the TV? The only reason why you must HDMI is to get 1080p and your TV doesn't support 1080p. Its supports up to 1080i. Your TV has a native resolution of 720p which means it can accept a 720p image and not need to scale it, so the picture will look the best at 720p but will support 1080i. I would use component cables to connect your sources and set them to output 720p.

Hitachi 53UWX10B 53 in. Rear Projection Television will it support the play station 3 is it 720p?


Check your TV back panel. If it has a DVI connector (like your monitor), you can get a HDMI to DVI cable and it will support both 1080i and 720p. My 57XWX20B has this connector. Good luck.

Green tint to picture when dvi cable is connected


The tv will show correctly in 720p mode. Cable box and PS3 must be set to display in 720p or the green tint will remain. For the PS3 I return it to 1080p when I am about to play a game, blu-rays and dvd's can only play in 720p.

1. Do I need any additional equipment to watch HDTV broadcasts on my HDTV-compatible TV?
In order to view over-the-air (OTA) HDTV broadcasts, you need to be within the reception area of a TV station broadcasting HDTV signals. Some TVs may require a set-top HDTV tuner and an external antenna to receive the broadcasts. Your cable or satellite provider may also offer HDTV channels as a part of their service, eliminating the need for a separate tuner. Please contact your local service provider to find out what kind of HDTV services they may offer.

2. What is CableCARD and how does it work?
HDTVs with CableCARD slots can accept a small card from your cable provider that allows you to receive standard definition and high definition digital broadcasts without a bulky set-top cable box. Please call your cable company to find out if they offer this service in your area.

HDMI, which stands for "High-Definition Multimedia Interface", is the consumer electronic industry's first connection capable of transmitting uncompressed digital audio/video signals. Components featuring HDMI can transmit both digital audio and video over one convenient cable, replacing the tangled mess that resides behind many home theater components. HDMI also offers improved quality over traditional analog connections thanks to all-digital transmission. Digital sources like DVDs and HDTV programming can now be transferred digitally from source to display without analog conversions that can degrade the original signal.

Unlike the HDMI interface, DVI only handles digital video. Through the use of an adapter, a DVI device can be connected to an HDMI device, but only video content can be transmitted. The audio signal would have to be transmitted through other methods such as analog RCA outputs or an optical digital output.

4. What's the difference between 720p and 1080i HDTV broadcasts? Does my CRT projection HDTV support both?
HDTV signals can be broadcast in either 720p and 1080i. It's up to the broadcaster which signal format to use, and both have their benefits. Our CRT projection HDTVs display 1080i signals in their native format. For 720p broadcasts, you can use the settings on your HDTV set-top tuner, cable box, or satellite tuner to convert a 720p signal into a 1080i signal that your TV can display.

Your widescreen TV has an aspect ratio of 16:9 (1.78:1), which is the aspect ratio of HDTV. However, movies are filmed at several different aspect ratios, including 2.35:1. Also referred to as "scope", 2.35:1 is a very panoramic aspect ratio that provides a wide field of view in the theater. Scope is much wider than your widescreen TV, so it still requires the use of letterboxing ("black bars") to fit the entire image on screen. Some TVs and DVD players have a zoom function that allows you to blow up the image so it fills the screen, but the sides of the image must be cropped in order to do so.

6. What will 4:3 broadcasts and DVDs look like on a widescreen TV?
There are multiple settings for adjusting the appearance of 4:3 material on Panasonic widescreen TVs. It can be viewed with black bars on the sides, preserving the way it was originally intended to be viewed. Some viewers find the black bars distracting, so they might prefer one of the stretch modes that lets you fill the entire TV screen with the image. One such mode is the JUST (justify) mode, which stretches only the outer portion of the picture while leaving the center untouched.
