Hi,
To my knowledge, most monitors would work with or without a driver. In your laptop pls press Fn + F? keys to activate the external monitor. Pressing on both combination would cycle on the choices of laptop display only, laptop + external monitor displays or external monitor only. The F? key would be specific to the brand and model of the laptop and would normally be with an icon monitor.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
Right Click on "My Computer", click "properties", click the "hardware" tab, click "device manager", expand "display adapters", there should be a video car listed, go to "properties", (click the resources tab and see if there is anything in the "conflicting hardware list" at the bottom) to make sure there are no hardware issues" click the "driver" tab and click on "Roll Back Driver" It should prompt you, click Yes/Ok, restart your computer.2) -OR- You need to installed drivers for your monitor to check this,
Right Click on "My Computer", click "properties", click the "hardware" tab, click "device manager", expand the "Monitors" tab, Check to see if your specific monitor manufacturer's name and model are listed. If it just says "Default Moniter", "Default plug and play monitor", or "plug and play moniter" you will need to check the disk that should have come with your monitor, -or- the manufacturer's website. Install those drivers as prompted by the manufacturer.3) -OR- your monitor settings are incorrect, such as your screen resolution is set to something that your monitor does support, or your refresh rate is set out of range of your what your monitor supports.
This fix is quite different depending on your OS, so if its none of the above, please let me know, and I can give more specific advise.4) Also please note, that sometimes, if you install a new video card, drivers are compatible, everything else is correct, but your power supply on your computer is not large enough to support it, your monitor can flicker, cut out, cause your computer to lock and freeze.
