I connect a desktop PC to this TV through the DVI port and get a red screen. The picture is clear but the whole screen just got a red tint. This just started a few days ago. It was working fine before.
I use the VGA port and everything seems to be normal.
I've tried a regular lcd monitor w/ DVI and it works fine. I've tried different DVI cables using the TV but still got the red screen. So I'm thinking maybe the DVI port on the TV went defective. If so, is there a way to fix it? Or is it some other reason?

There should not be a driver required for this. As long as your HP desktop has a VGA video or HDMI video output, you can connect to the back panel of the TV from the video port of the PC. Then, on the remote, select the "PC" option for VGA input, or HDMI for the HDMI 1 or 2 input(s). If the PC only has DVI output, then it is important to know if the output is analog or digital. If it is digital (DVI-D or DVI-DD] then there is no available port on the TV to support it. Using a DVI-VGA adapter on a DVI digital output will not work as there must be a digital-to-analog conversion in order to work.
All modern TV's can be used as computer monitors - you just need the correct cables and select the correct input on the TV.
What cable are you using to connect your PC to your TV? VGA or HDMI? Your listed TV has both ports but your computer may not have a HDMI port. Either way, connect the correct cable from your PC to your TV and note how the port is labeled.
Turn the TV on and then find the "Input Select" button on the remote and press it until the above port appears on the screen.
If you use the VGA port, you will need to hook up the audio from the PC to the "PC/DVI Audio In" port so the sound will play on the TV speakers.
If you really want, you can use an old CRT TV as a monitor provided you get it connected.... so your plasma... YES. If your PC has a DVI port, you could use a DVI - HDMI cable to connect. If your PC does NOT have a DVI port, you could install a video card that does... better yet, get a video card that has a HDMI port. This way, you'll only need a HDMI cable to connect the PC to the TV for audio and video.
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.
The video cable should be a VGA cable, assuming your computer has a VGA connector. Get one that has M/M ends. This is sometimes listed as a 15 pin D-sub connection. Then connect a 3.5 mm audio patch cord (m/m) between the audio out (speaker/headphone) pf the computer to the TV's VGA audio in (if you want to use the TV speakers).
If your computer has an HDMI or DVI output, I do not believe that you can connect to the TVs HDMI port. (The signal from the computer is not the same as that from a set top box.) If you have a DVI port, get a DVI to VGA adapter and then connect to the VGA cable. (You could use a DVI-DVI cable and then the DVI to VGA adapter at the TV. However, space is an issue at the TV.)
Make sure that the VGA port is enabled on the computer. (Some newer computers have a different video port enabled initially.) This may require entering your BIOS just after turning on the computer. Usually you need to strike Esc, F1 or F2 repeatedly starting when you press the power button. (F10 is also a BIOS access with some manufacturers - the key will be listed in a splash screen that is only visible for a few seconds.)
With the computer and the TV off, connect the cables. Then turn on the TV and set the input to VGA. Next turn on the computer. (If this is the only monitor attached, the computer should find the correct resolution (Windows). If you are using a dual monitor option, then you may have to enable the TV as a monitor. This will depend on the OS. For my Windows 7 laptop, it's right click on the desktop and choose Graphics Properties. Set the monitor options for both, external or attached and click Apply. Then click OK when a confirmation window appears. With my Windows 7 desktop, it's right click on the desktop and choose Screen Resolution. Similarly choose the settings, click Apply then OK to confirm.)
When you connect the DVI, try hitting the input, source, or conection button on the remote on TV. Some vendors use different names for the button. Use the procedure below to set the resolution for the second screen to 640X480 first, then move the resolution up one notch at a time to see what your TV can handle. Many televisions don't allow an input through the VGA connector that's a higher resolution than 640X480. That is probably the format that you see appearing on screen where everything looks huge. You may be able to increase from that slightly after getting 640X480 working.
When you've made all the cable connections right-click on the desktop, then choose PROPERTIES from the bottom of the list. A small window will appear with a few tabs on the top choose the last one, SETTINGS. Click on the screen shown on this tab with a numeral 2 shown. On the middle-left you'll see a slider showing large and smaller at each end, bring it down to 640X480, then hit apply A pop-up will appear asking you to confirm that this size is working, click yes if when it does. Try increasing the resolution by a notch to see if the next size up works with your TV. If you see the Invalid Format on your TV again, you've gone higher than this particular input on your TV will accept. To get a higher resolution signal you made need to switch to a different cable type, try DVI or HDMI. Either of the two should work more automatically than the VGA cable you are now trying. If your computer only has a DVI port and the TV has an HDMI port you can get a cable that has DVI at one end and HDMI at the other by clicking here:
LCD TVs are the best at showing computer graphics, so many come with PC video connection ports by default. If it does have one of these ports, all you need to do is get a cable to connect to it. This is usually a male-male cable. Be warned, however - stores like Best Buy and the like tend to horribly overcharge for cables. Check prices online at places like www.newegg.com - I found some from $6-$10 with $5 shipping. They'll probably be $25 minimum in a store. Also, if it's a DVI connection, don't get a DVI-A cable - that's for analog connections. DVI-D is for digital connections (specifically for connecting to LCD screens) and DVI-I cables are for both, but be sure to get a DVI-D cable.
Check out this link and look at the picture of the DVI-D and DVI-A connectors:
My video card has a DVI-I output, but my monitor only has a DVI-D input, so I can't use a DVI-I cable on it (DVI-A and DVI-I both have 4 extra pins that DVI-D doesn't).
If it's got a VGA port then whoop-de-do. There's only one type of VGA cable anyway. ^_^
If the TV has a DVI or HDMI port you may be able to connect to your PC that way. Your PC will have to have a DVI or HDMI out put to support doing this. The other possibility os using VGA but I doubt the TV has a VGA connector on it.
