If it's a HD tv then yes, otherwise you are watching a lower image resolution than your tv is capable of.
HDMI is a standard interface for standard and high definition video signals and is independent of the equipment that is connects. Ensure that any HDMI cable is HDMI 1.3 compliant. All licensed HDMI cables have been tested and approved for a maximum length. If the cable is properly licensed, it will operate without problems. Remember that price makes little difference - either the cable works or it doesn't. Make sure that the cable is bought from a reputable retailer and has the HDMI logo on it to ensure it is compliant.
Get the HDMI cable
No. HDMI cables will need an HDMI input and only HD capable TVs will have them.
You can get any brand. Just make sure the connections are the same. Radio shack has a bunch. But answering your question; no you don't need PS3 issue hdmi.
There are two different connectors used for HDMI one is normal size and the other is a mini HDMI plug. Even HD movie cameras use a a combination HDMI Cable, one end is normal sized to connect TV, the other end is mini HDMI to connect camera. If you need a cable Look for HDMI on the display, make sure you get the one for the particular equipment you will be using it on.
HDMI cables should be manufactured to the HDMI standard and have the HDMI logo on the cable or packing. The logo should guarantee that the cable will operate correctly. Because HDMI is fully digital, a cable will either work or it won't. There will be no improvement in quality by purchasing more expensive cables. Claims by manufacturers that their cable must be used for "full quality" or "best quality" are misleading. Certain manufacturers offer cables in excess of $300. Be assured that they will provide EXACTLY the same quality of image and sound as a $10 cable. Of course, the $300 cable might look better! Although some cables may be more robust than others, this is only likely to make a difference if the cable will be repeatedly connected and disconnected. Other than that, expect the lowest cost cables to perform as well and last as long as the most expensive.
You will need an HDMI cable to connect your flatscreen tv to your HP Laptop. Make sure your HP Laptop has an HDMI input as well.
Assuming you have already tried unplugging the hdmi cable, and re-attaching it to make sure it is tight..... First, I would figure out if the hdmi output is bad on the DVD player, or if the hdmi input is bad on the tv, or if the hdmi cable is bad. Of course to do this, you would need a second hdmi capable tv, another hdmi source device and another hdmi cable. Once you figure out the source of the problem, decide it that component is worth replacing. Or, just run component.
For an HDMI cable 10 yards is the maximum supported length, so it should probably hold it's signal. It would help to buy good quality cable, just to make sure.
No. It matters only when you are dealing with an analog signal. With digital signals the signal is there or its not. There is no improvement by choosing the really expensive monster cables.
The purpose of an HDMI splitter cable is to take HDMI signal from a source (such as satellite television service) and split that signal to multiple televisions. Such splitter cables are very handy to have when one owns more than one high definition television and wishes to enjoy high definition programming while saving money.
Make sure cable is seated properly at both ends. Unplug and re-plug. If this doesn't work you may have a bad HDMI cable or the HDMI interface on your TV or computer stopped working. On the computer there may be a way to turn the HDMI port on or off. You have to eliminate all these possibilities. Replace the cord, plug the computer into another TV or drive your current TV from a different HDMI source using the same cable.
