What cables would I need to set up a second monitor & set up my TV as a second monitor as well I have a BENQ 2201

It may have shorted out transistors, bad caps, etc. You need to open it up and do in-depth troubleshooting, but please read my guides first.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

The message is being created by the monitor not Windows. The only thing you can do is look for the option to disable it on the monitor's menu options. NEC-brand monitors will have something call "Onscreen Notification" which you can disable. Hopefully your BenQ will have a similar option.

Good luck!

You need to set up the extra monitor in your display settings, as there's no output by default.

i want data for benq q5t4 moniter eprom 24c04 ic my moniter is not working properly

Hello
Check your cable, ask the cable operator about the signal, if these are OK, then the TV tuner gone faulty which needs repair.
Good Luck

Try connecting the monitor to a different computer, e.g., a laptop.

The power-cord to the monitor seems to be OK.

Check the "data" cable between the monitor and the computer -- try a different cable.

With the monitor turned on, restart your computer, and watch the monitor. The computer should show some start-up messages (white text over black background), followed by the Windows "splash" screen. If it does, the monitor is working correctly.

Make sure the cables are in well with a good amount of slack, it can cause a problem if your power cable or computer to monitor cable is loose

Here you go:

ive solved this by taking out my vga cable and plug in my dvi cable and ive done some settings on my ati control center i have x1300 512 mb all you need is change your settings that this lcd dont support plus this monitor is huge!!!!!!!!! thank you for your support lol

If it is still under warranty from Benq (3yrs), call them for a return. I have one (FP731) and did the same thing. There is an IC within the monitor that is bad. Pretty soon there will be nothing on the screen.
