I don't think you can really do an HDMI to VGA or HDMI to DVI to VGA. If the monitor doesn't support DHCP, it probably won't work with the HDMI output


Please specify which cable are you using for video signal.

    In case you are getting video on safe mode than try to remove the driver in safemode and when you will go back to the normal mode try to install the latest video driver and set your display to lower the resolution down to
    1152x864 or 1024x768 and tell me the status.

The problem is that your hertz rate is set to 75 and your acer monitor doesn't support that. Go into the display settings and change the hertz rate to 60.

I've seen this error when replacing a CRT monitor with a Flat screen.
If you have a CRT monitor around, plug it back in, and change your video settings.
Lower the resolution numbers (800x600 should be fine) and lower, or match your refresh rate. (it should have the ratings on the back of the monitor)
Find what your Acer is rated for (probably 60 to 72 Hz).
You may have to swap them back and forth a few times to get it right, but once you do get it to display, you can get it to "talk" to each other, and fine tune the display rates.

Let us know how this works.

You may want to check the output settings of your computer:
This can be done by right clicking on the desktop, going to 'properties' in xp, or 'personalize' if you are on vista
Then go to the settings tab, and set your setting to 1024 X 768
See if the message is removed. Also check your cabling! Make sure all plugs are inserted properly!

    to change the hertz setting, under the settings tab, click 'advanced' and then 'monitor'


    there change the hertz setting to 60HZ

  • Anonymous Aug 07, 2008

    and yes it does seem like a hertz setting problem, so no need to change resolution! just follow the instructions and change the Hertz setting to 60 HZ

The problem is that your hertz rate is set to 75 and your acer monitor doesn't support that. Go into the dispaly settings and change the hertz rate to 60. Fixed my a couple of minutes ago.

When i put pc on this message comes up on screen saying input not supported and it floats round in a little box.

Hello,
This generally means you have the display resolution set higher then the monitor can support. To fix this press F8 after you turn the computer on. You may have to press it a couple times before the windows loading screen. A black menu will come up. Select safe mode. Your PC will load into safe mode with minimal drivers and settings. Go to the control panel and select display. Change your screen resolution to something lower then the setting is is at right now. If your screen is 19" or smaller try a setting of 1024x768 for starters. If its 20" or higher try 1280x1024 for starters.
Regards, Chris

Input not supported on my screen I have a Acer P191W monitor

your resulition is set too high. to fix this you need to either change it on another screen if you have one or restart your computer into safe mode. usually in safe mode it will be on the lowest setting and you will have full access to change it from there.

How to change resulution when you get input not

Try starting Windows in Safe Mode. During boot, before windows starts loading, just keep tapping F8, until a menu appears in which you can select Safe Mode. In Safe Mode, set the resolution to a safe, low value in the control panel. Then reboot normally, and everything should work fine.

Monitor

When your computer is starting up, hit F8 and you'll see the safe mode, safe mode with networking, etc. screen...You should see a choice that says "enable vga mode". Select that and windows will start and the os will select a screen resolution for you. After that, everything will work fine...I hope.


Good Luck!

Input not supported

You may have a video resolution selected on your computer that the screen doesn't support.

The reason you see the the initial startup message is because that is loaded from the bios, prior to the settings for the graphic card output being loaded.

Try booting the computer in safe mode and adjusting the display resolution.
