    Monitor Acer G205HL turns on then off


    Hi, hope someone can help!

    I've just got a brand new laptop (windows 8.1) and purchased a G205HL monitor. I'm having problems with the monitor just turning off and then on after a few seconds. Input is VGA.

    Windows recognize the monitor as Generic PnP Monitor in the configuration panel, frequency 60 Hz.

    With my old laptop (windows 7) the monitor works properly, so I don't know if it is a a driver/monitor problem whatever that's causing the black screen

    Any help would be appreciated

    That's normal and not a problem. Note that monitor drivers are not really drivers at all so you don't really need to install them. All they do is supply Windows with the monitor name, and the resolutions it supports so the unsupported resolutions can be grayed out.

    Are you pressing the necessary Function key to switch between notebook monitor, external monitor, or both?

    You didn't tell us anything about the notebook so we can't really help with that other than to say to refer to the manual.

    Thanks for your answer!

    The laptop is a Lenovo Z50-70 with Windows 8 and a graphic card GeForce 840M. There is a hotkey that helps to set quickly the external monitor (F9). But when I toggle the display between my laptop and the monitor using this key I have the same issue as when using <Screen Resolution Configuration>.

    The native and maximum resolution of the Acer monitor is 1600x900, and the one from the laptop is 1920x1080. Maybe this is the origin of the turning off-on of the monitor. But when I try 1600x900 still doesnt fix the issue.

    Since this notebook is brand new, I think you should contact Acer. You don't want to do anything that might jeopardize your warranty and you need to get on record you are having problems.
