Optiplex 745 monitor goes to sleep randomly


In regards to your issue with your monitor: For a monitor to display "no signal input" there is likely a problem with the monitor making a connection to your input source (yes I know duh). First and easiest thing to fix this is to check your cables going between your computer and monitor, if your computer and monitor start out working and then fail to communicate, there is a good chance that the cable might be coming loose just enough that the connection fails. I might suggest that if you have, as you say another computer, that you try swapping monitors to check where the problem lies.

Hope this helps some.

HP w2207 no vga input signal, no dvi input signal monitor goes to sleep


There is no signal coming from your PC.
excuse some of the solutions as sounding dumb, but we have to explore all possibilities.

Check the power cable going into the computer
Check the power input disconnect switch on the back of the power supply and make sure it is on
If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped
press power on the PC and make sure the lights are coming on.

now for the solutions that may actually help.

disconnect the power from the PC
if the video is on a card, remove and re-seat the video card
hook the power back up, connect the monitor and try again.

the CMOS on the computer may need to be reset.
I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up.
If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.

Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)

I just purchased a acer h203h and when I hooked it to my computer it says no signa and light turns red.


Please check the video input selected, press Menu botton, the monitor will show you among other information the input selected, if indicates VGA, you must have connected the corresponding cable between your PC and monitor, if it indicates DVI and your computer doesn't have DVI port press the Input botton to select VGA.

My dell 4700 won't come out of sleep mode, i've rebooted and changed the internal battery but still no luck


Get some canned air - 2 cans
unplug the monitor and computer.
Use canned air to blow out all the vent holes of the monitor.
Leave it unplugged for about 1 day.
Open the computer case. Use the canned air to blow out the computer. pay special attention to fans and the power supply - actuall blow the air through the power supply vents on both sides.
If you have an add on video card (not on the motherboard), remove the screw at the back of the case, and remove the video card. Reinsert the card and make sure it is tight. replace the screw.
After the day is up plug the monitor back in and use the buttons on the front to enter the monitor menu. Choose to reset or factory settings.
Hook it back up to the computer and boot the computer.
If the problem still occurs try the monitor on another computer or laptop.
If the problem goes away by hooking it up elsewhere - replace the video card.If you are not sure what type to purchase just post back model and serial of the computer.
If the problem is still there after hooking the monitor up elsewhere,
Try changing the video cable or seek rpelacement through warranty or purchase a new one. Check newegg.com for best prices.

As soon as i turn on my computer my monitor says no input signal and then goes to sleep i have an hp


either your video card has stopped working or your cable to your monitor or the monitor is bad. Try to hook another monitor up to it see if it turns off if it doesn't then the video card needs to be replaced. If it does its the monitor.

Desktop has no signal


That means that the input from the monitor has no read able signal
Either the monitor is bad or the onboard or video card
Take the monitor and hook it up to a different PC to see if it works or hook a different monitor into that PC, that will ID which problem you have

Bought Samsung 2233BW Monitor, hooked the two plugs, power and DV1 cord started computer and switched on monitor, NOTHING HAPPENED. Silly thing just unhooked Samsung and hooked back up the AOC monitor no...


You might need to go into the monitor's setup menu and select the digital input. (That's DVI, by the way, for Digital Video Input, and not DV1.) Some monitors automatically detect the input but not all of them. Obviously, this doesn't apply if the Samsung has only a DVI input. It might also be necessary to tell the video card to turn on the DVI output. You can do this with your old AOC connected and use the video setting utility supplied with the video card.

Monitor malfunction, says VGA Input: No Signal and goes to sleep


If it was your video card, you would have no picture at all. Try to boot in safe mode and do into your options and make sure your hibernation is not on. Only other thing I can think of, it could be *********** board.
