Question about Chi Mei Corporation 221A Monitor

1 Answer

No Input Signal

Hi When I start my computer monitor starts fine but will go black (as if in sleep mode but will not restart but computer is still running) green light goes to orange. Works if I connect another monitor to my computer at same time but is very annoying. Monitor is 11 months old. Had this problem when first received it and returned it to store and they replaced the monitor and it is now happening to this one. Any solutions?

    I have the same problem with the 22" Chimei "No Input Signal". When computer is awaken the Chimei stays orange light. I have to restart computer for the Chimei LCD to work again (green light).
    Also now when computer starts, the Chimei starts up ok, but when Windows starts up I get the dreaded "No Input Signal"
    I can get into Windows under VGA mode, but if I change resolution I get the "No Input Signal".
    Have changed VDO cards still same problem.

    My monitor reports a "No Input Signal" problem when booting Windows Vista 64... but can start fine in safe mode, to try and solve this I have reinstalled all driver software, but still does not solve the problem, my monitor is a CMV223D and is about 1 month old.



    What is the fix for this problem?

    Hi All,

    I have this problem too.. seems to happen every time there is a windows update. I managed to fix it by unplugging the Digital and using AGP.. restart PC... then unplug AGP use Digital again and Voila! but for some reason it hasnt worked with this latest upgrade

    Same problem as all of the above. It's very sporadic, and if I mess with it long enough, I can get it back up and running, but there's no telling when it will lose it's input signal again.

    The "solution" below is not accurate. The problem is not with the connection, it sounds very much like a problem with this monitor model.

Dont Panic it is Nothing...
Your Monitor is safe...
If it say "no Input signal" - "Check VGA cable"

it means that the Monitor is finding signals from the computer,and the cable is either not connected or unsecurely connected.

IT is most probably windows 7 issue. I saw problem with desktop computers coming back from sleep for many times.

I advice you to avoid sleep. If that is not issue, first test memory, cause sleep stores everything to the memory.

Please tell which OS you use ? As said on start it might be Windows 7 ...

Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

No DVi input, then computer goes to sleep


Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:
  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

I have the puter that has the start button on top of it.....not too crazy about it.....

hope this works for you.........Judy in NY

When I select sleep or hibernate mode - the monitor stays black...


Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
