    HI everyone,

    So I have a Lenovo Ideapad y550, and I am using windows 7 home premium. I have an Acer lcd external monitor that I want to run. I bought a DVI to VGA adapter to connect my monitor to my laptop. So whenever I plug it in my laptop to recognizes in completely, but the external monitor is still blank. It has a blank screen and the power light is a solid amber color. I tried updating the drivers, but seeing as I just got my laptop a couple of weeks ago, there are no new drivers for video/monitor display. I tried seeing if my connection was loose. It was not. the connection is fine. I have hit Fn + F3 which sets it up for extended use. I know it is working but my external monitors screen is blank. Any suggestions please? Thanks.

    Hi There!

    Check the resolution of your laptop, compared to the supported highest resolution of the monitor, perhaps you need to adjust the resolution of the laptop if it is set to a resolution that the monitor doesn't support or vice versa.

    If that doesn't help...Do you have another monitor that you can swap to rule out the culprit as the monitor itself?

    Or...Do you have a VGA cord that you can connect to the monitor to see if you get a signal?

    Thanks for your quick response, but unfortunately I tried all of those things just now, and nothing happened. I tried it in a different LCD monitor. then i tried it with a CRT monitor with VGA. And I also tried changing the resolutions on all three of the monitors. What else can i try to fix this. Thanks.

    Do you have the same problem when running in "Safe Mode"?

    When I run it in safe mode, the monitor is not even recognized. Plus I tried to manually detect the monitor, but nothing happened.

    So, none of the external monitors are working when connected to your laptop?

    Did you go into the display properties for your video adapter, to verify the correct settings needed
    to use your external monitors?

    definetely go to display properties and make sure you you have set desktop to extend...sometimes the hotkeys aren't enough. also, try setting it up so you use ONLY the external display and see if u get signal
