HDTV cabling

by Bill Osler / March 17, 2009 8:58 PM PDT

I've seen a lot of stuff about 'digital' connections for HDTV. Am I correct that HDMI is the only truly digital method for video connections between HDTV devices in the home? My impression is that Component Video can be used to send HDTV video signals, but I've always assumed it was a high quality analog signal.

Is there any difference in video quality between HDMI and Component Video?

digital video and audio in 1 cable

1080p resolution (highest) through hdmi. I think there
are some hdtv's that do accept 1080p through component
,like new westinghouse, but when you can get an hdmi cable
for $5 or $6 shipped to your house why bother. Besides the
highest quality audio and video connection there are several
advantages that the hdmi connection gives like hd audio
formats from blu-ray, 1 cable connection, better compatable device control, etc.

componant can do 1080p and beyond but its an analog signal and hdmi is digital.theres a little conversion the analog has to do so digital is all the way to the tv so best but most people cant tell.Some tvs do better at the conversion than others like on a sony i couldnt really tell but my samsung i thought was better with hdmi.

HDMI is a fully digital signal that carries both video and audio. Component is an analog signal that carries three components of the video only signal and does not support progressive scan.

To most people they will look the same on an older 1080i or 720 resolution TV. On the newer -p sets with high refresh rates component is not available. If it is the output picture is downgraded.

On newer TVs there is a difference.

OK, so component video does not reliably maximum resolution and it is analog.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
