May I ask to what you mean by "adjust the resolution in safe mode, this has not helped"?
Did you set it to native resolution of this monitor? Unless it has problem inside the monitor, try it with another PC also.

Appears on screen"input not supported"


Start windows in safe mode - press F8 on the keyboard during the boot process and wait for the startup options menu to appear. Select Safe mode and see if this works. If so, then once in safe mode, change the display settings to a lower resolution. the maximum resolution for this monitor is 1024x768. Set it to 800x600 to see if it works at the lower resolution first.

I am in charge of a computer account here at work and have about 15 ACER 1916B monitors that are all inop...The monitors power up and show the ACER startup then show the windows startup to only go...


This problem is caused by 2 things, the computer is set to a higher resolution that the monitors can handle, so when the graphics card drivers kick in as windows boots the screen goes blank, this is normally the problem for people trying to hook there computers to normal lcd televisions not monitors, as monitors generally are able to show higher resalutions.

In your case because you are using computer monitors, the problem will be caused by the refresh rate settings on the windows, most desktop lcd monitors have a fixed refresh rate of 60hz, my guess is your computers are set as 75hz therefore as windows boots the screen goes blank because it dosent support that high a refresh rate.

To resolve this problem, just before windows boots press F8 on the keyboard, this should bring up a black command prompt screen, at the top you will see the safemood option, tab up to it and press enter, this goes to windows but dosent load any drivers including the graphics driver. Once loaded right click the mouse in the middle of the screen, and bring the display properties window up, in this window click on the settings tab, click on advanced on the bottem right of the window, this will bring up another window, click on the monitor tab, on this window you will see the screen refresh rste setting, click the small arrow and set this to 60hz and click ok, in the other window reduce the resalution down abit using the slider, click apply and close the window, then reboot the mechine as normal, the problem should now be sorted, any problems post me back. thanks and hope this helped.

Our acer 19in LCD monitor goes blank after initial startup and msg "Input not Supported" appears. Startup msgs are shown but once Windows XP starts, this error appears


Your resolution is set above what the monitor supports.

when computer is first starting up hit f8 to get to boot modes.

choose Enable VGA Mode: This option starts Windows in 640 x 480 mode by using the current video driver (not Vga.sys). This mode is useful if the display is configured for a setting that the monitor cannot display.

When you are booted into windows you can then set your resolution to the highest that the monitor supports which is 1440x900

Let me know if this helps.

Input not Supported


The signal being sent is outside of the rated limits of the monitor (vertical or horizontal synch rates). Boot up in safe mode (by hitting F8 during the initial startup of the computer, before the windows logo screen comes up). Select Safe Mode. If you get a display in this mode, then you know your graphics card is sending a signal outside of the monitors limits, if not, then the monitor itself is probably bad. NOTE: The following steps are for Windows XP only... if you have a different OS, please reply and I'll research the steps for you.

If it is your graphics card, while in safe mode, right click on My Computer and choose Properties. Click on the Hardware tab. Click on Device Manager and double click the Display Adapter entry. Right click on your graphics card and click uninstall. This will force the computer to reinstall the graphics drivers at bootup and, hopefully, reset the adapters output mode. Reboot the system and once in, set your display settings to the best for your monitor (Windows XP should pick the best setting if the monitor is plug and play).

RectangulaR box on my screen says: input not supported


If your monitor is displaying a message, that's good news: Your monitor is not shut. What the message is saying is that either the refresh rate frequency, or the resolution you have set your video card to on your pc/laptop, is too high for your LCD (I assume) monitor, and it cannot handle these settings.
It would appear that the default refresh rate for LCDs is only 60Hhz.
Reboot your machine in SAFE MODE, pressing the F8 key repeatedly as soon as the initial POST messages disappear from the screen. Next, select Safe Mode from the different options shown.
Once the PC starts and you're running Windows, go to Control Panel->Appearance and Personalization->Adjust Screen Resolution->Advanced Settings->Adapter->List All Modes and verify that the resolution that's been set is within the range allowed by your monitor.
Your user's manual should have this information. In case you don't have this information, change it to something safe, like 800 x 600 pixels, at 60Hz refresh rate.
Close all windows, reboot, and Voila! Your monitor is back to life!
Should you wish to continue to improve your monitor resolution, then right click anywhere on an empty spot on your desktop, and choose Personalize->Adjust Display Settings, and try a higher resolution, remembering to leave the refresh rate at 60Hz.
Good luck!

Blank Monitor


Start pressing F8 at boot

When the Windows Startup menu appears, select ENABLE VGA MODE

This will boot the system in 640 x 480 resolution but the video driver will be installed. Once at the desktop, either reset the display to the normal resolution settings or reinstall the video driver.

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!

Monitor blank when startup, have to restart several times


The problem is probably caused by the LCD's inverter.
I had problems like yours with some Acer laptops and had to replace the LCD's inverter.

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.
