LG L246WP-BN 24" LCD and DVI / HDMI & Component video

I finally got a chance to hook up my LG L246WP-BN 24" LCD to my set-top box that receives over-the-air digital broadcast television signals using the DVI / HDMI cable and some other component video cables I have.

(recalled from shoddy memory)
First off, if you didn't know, there is DVI-D and DVI-I. DVI-D is what is on your soon to become legacy video card. Then there is DVI-I which is on the back panel of most peripherals such as dvd players. It is the DVI-I connector that is at one end of the supplied cable with the other end being an HDMI connector.

(carrying on)
Any way, I connected my lcd to the set-top-box using this cable. switched the lcd to HDMI iinput and it came up crystal clear. But your signal must be perfect or you may get some artifacts at the top edge or side edge of the image. This could be due to the broadcast not being perfect from the station's end or interference or an older model set-top-box. (Mine is over three years old.)

I had a perfect signal (clear with no artifacts) of the PGA golf tournament this Sunday and it was literally just like being there. Totally impressive display.

I switched over to component and it was without any artifacts on any station. It seems that the component signal is more reliable but when you get a perfect DVI signal it is much nicer to watch. But both are great. I think that DVI has slightly more saturated colors and better contrast than component.

I'm going to start looking for the newest set-top-box I can afford.

Also note that in addition to all the new motherboards coming with integrated HDMI, the new graphics cards are coming with HDMI. So soon you'll be able to hook up you lcd monitor with a cable with HDMI connectors at each end.

I'll be posting another thead talking about lcd resolution and broadcast television resolution.

Not so obvious what is going to turn into a legacy connector. HDMI might be all the rage now, but DisplayPort could well displace it. Maybe HDMI will be legacy, and DVI will soldier on as VGA does.

Whatever you buy

is already

obsolete

HDMI doesn't support dual link, so DVI isn't going anywhere.

Does the LG do 1:1 pixel mapping? I'm assuming it is 16:10 1920x1200 default display, whereas your TV HD signals would be 16:9 (1280x720 or 1920x1080). So you should be getting black bars at the top/bottom if the aspect ratio is being preserved (720P upscaling or 1:1 pixel mapping on 1080i OTA signal).

If the signal is taking up the whole display it is stretching the image vertically (from 1080 lines to 1200 lines) and giving distortion.

Good point!

DisplayPort does support 2560×1600 with single cable

Yes.

Two of my buddies have it; it does indeed feature that.

It also will do upscaling to fill the display as well for most of the inputs afaik, though iirc, not on composite, just on component, VGA, & HDMI/DVI.
