I have a "purple" stripe running verticaly down the left side of my screen in all modes (Cable via HDMI and VGA) It looks like the video is wrapping around, and I do not know how to adjust it.

Replace power supply back of TV.

Here you go. Some very inexpensive and they work well.

restart pc in safe mode, change video back to standard VGA of HD VGA video. PC has to be in HDMI mode and your TV has to be PC mode. Use a DIV to HDMI connector or better yet HDMI to VideoPort if your TV supports it, HDMI almost never gives you the screen output you really want anyway.

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

(You can also use an HDTV if it has an HDMI port, and you have an HDMI cable. The HDMI port is on the Left side of the laptop, too.

{Don't buy an HDMI cable that is expensive. Just a waste of money.
Those gold plated parts are just a little bit better, than an HDMI cable that doesn't have it. $20 for an HDMI cable is PLENTY. (12 Feet) I use one's that cost less )

A) Laptop OFF, monitor (External display device) OFF.
Connect the VGA monitor to the VGA port, on the laptop.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

There ARE at least 3 display options available;

1) Internal monitor ONLY
2) Internal monitor AND external display device (VGA monitor in this example)
3) External display device ONLY

Press, and hold the Fn key down, tap once on the F4 key.
(The F4 key is the Display Toggle-Over key)

Wait a few seconds.
Still no?
Hold the Fn key down again, and tap once more on the F4 key.

If Your TV and Laptop have HDMI Port then you just need a HDMI Cable.
But if you dont have HDMI port. then you need two cables one from video and one for audio.
For Video you either VGA Cable(if you have VGA Port in your TV) or VGA to RCA Cable (Yellow Pin will be for video)
For audio You Need 3.5mm pin to RCA (white and Red for audio).
This pic is of VGA to RCA Cable

For making the physical connection between PC and TV first we need video cable.
PC has S-Video port that should be connect to the S-Video input of your TV using S-Video cable.
Connect the computer to the TV using VGA ports or via the DVI to HDMI cable. These Macs need Adapter for a VGA cable.
RCA for audio, connect RCA to your PC and red and white colored sockets of RCA cable to TV (left audio-white, right audio-red).
In your PC open the Display Settings and activate output to the TV screen.
In your TV open the menu from that open the External inputs. And change the video to HDMI depends on the connection.
You can also change the screen resolution of your TV using the Personalize and Display Settings options in your Control Panel on PC.

After giving the connections you can watch the movies and everything is running on laptop on TV.

What "video-inputs" does your TV have:

* composite video (single cable for video, two cables for LEFT/RIGHT audio)
* component video (RED/GREEN/BLUE cables for video, plus RED/WHITE cables for stereo audio)
* DVI or VGA input
* HDMI input
* S-Video (similar to PS/2 keyboard/mouse, in size, and "round" shape)

What outputs does your computer's video-card have:

* composite (post-and-ring)
* S-Video
* DVI
* VGA
* HDMI

Just match them up.

If the computer is running Windows 7 judging from the age of the computer you may need to update the operating system and then get new drivers for the NVIDIA card.

You need an HDMI driver... also sometimes a special HDMI cable is used for Apples too, I believe. Also a lot of sets must start with a resolution of 800x600 32bit. Also research if HDMI is actually possible from your video card too. Some HDMI doesn't send the audio via the cable either you must use AV audio out.

The easiest way would be to purchase a video card that has 2 vga ports on it, allowing dual monitor support. Here is an example.
