If you are not a technician you can´t solve this problem because are to desasembly your device and check the Q7 and Q8 and C5 that components are on bad conditions and need to be replaced,I told you because i repaired one of these monitors for the same problem

Are you sure that your problem is with the monitor drivers? Usually when graphics card drivers are correctly installed, the monitor is recognized as "Plug and Play monitor" and this is completely sufficient, as the monitor is able to communicate it's supported resolutions and refresh frequencies to the video card.
Look for an updated graphics driver for your system - first you have to establish what type of graphics card you have, then find drivers for it.

well friend if the fuse is the problem, you will not see any power light indicator. probably theres a problem in power supply circuits or most probably the horizontal deflection circuits. which includes the horizontal oscillator, horizontal drive, horizontal output and maybe the flyback itself. but if you dont know anything about this, better bring it to a qualified tv technician. good luck!

I have one with no backlight. The capacitors on the board are bulging. In my opinion they were designed too close to tolerance and "cooked out". As long as it's still working change the ones in the Regulator circuit(3 in the middle of the heatsink area), and the four really small ones over by the transformers. Should be right as rain.

Try to use another power cable, or another power socket . If won't on, maybe you have problem with the monitor. Have you pressed the power switch?

You need to remove the standard windows monitor driver in the device manager and reinstall the monitor driver. Search in google and download the driver and install it. Good hunting.

Yes, you can use the 'Generic' option in Windows, assuming you are using Windows Bruno
