How do I dry my laptop screen?

I have my laptop and HDTV connected,but how do I set it to clone FULL SCREEN on both the tv/laptop?

• I've had my laptop connected to my tv using a single yellow cable/S-video (which does enables me to set the display to clone in full screen.) Now I've purchased a composite cable (red,green,blue/S-video) and now it won't display on a full screen resolution. My laptop is set on 1024 x 768 (perfect) and I want to set my 2nd display (TV) the same, but the closest resolution it will allow me is 1280 x 720 or 1152 x 648 and the results are two blank bars on the left/right sides of the screen, but the picture is noticablely HD (couldn't get that with the single yellow cable). So basically, how do I get it to "clone" like it does with the yellow cable but with HD capabilities. (also, when I set it to Extend rather than Clone the resolution still can't be full screen on the tv) Please help.

• Answer:

  The problem is your HDTV is a 1280x720 widescreen 16:9 ratio and your laptop is a 1024x768 4:3 screen ratio. What is set at fullscreen resolution on one display does not match the same fullscreen on the other. The reason you were able to do this before was because the old S-Video method was analog and can output fullscreen on a TV but only at a standard TV resolution (not actually at 1024x768). So if your screen was set at 1024x768 on your laptop, it would still be showing that on your TV but at 720×480 SDTV resolution (which is why this would be fuzzier than the original). With a digital connection, you can't do a true clone of your laptop without having black bars on the edges since 1024x768 does not display in fullscreen on your 1280x720 HDTV natively. Some graphics cards may allow you to set custom resolutions for each display, but you can't do a true clone at the same resolution without getting black bars unless both monitors (or TV in this case) are capable of displaying 1024x768 at fullscreen.
