    Turned out to be a broken USB port (somehow ? ?) but thanks for trying. Much appreciated.

Try downloading and reloading the video drivers for your PC.
It could be that they corrupted.

#2 If you plug a different monitor into the PC, does it do the same thing?
If yes it does the same, it's a problem with the video card.
Try the drivers, or you may need to replace the video card.
If no a different monitor doesn't have the problem, it's a problem with your original monitor, and you'll need to replace the monitor.

My hp pavillion dv7 1245dx screen has a red tint in the background?


Your lcd screen is bad. It's either the lcd screen or the video card inside the computer, but most likely the screen. You can isolate the problem by connecting an external monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok without the read and green tint then your video card inside the computer is good but your lcd screen is bad. If the Borrowed monitor displays the same red and green tint then the video card inside the computer is bad.

It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Is there a new windows 7 driver for the Samsung Syncmaster T240 monitor? The problem I'm having is green flickering, where a green tint intermittantly comes over the monitor.


try reducing the refresh rate of the screen. I Hope the Driver for the moinotor is installed !!

But if it is intermittant..
Then Monitor may be going through normal ageing.

My screen is light green i don`t know what to do ;/ whats can by bad ? please help me :S


I am not sure if you are talking about the green power indicator light, or the screen is showing image with green tint.
Check the VGA cable first make sure there are no bent pins, tight connections. Try it on other PC also, we just need to narrow down the problem first.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
