I just bought an SVA monitor i wanted to know if it is compatible with an Emachines CPU? The screen keeps saying "Unknown Mode" and :Entering Sleep Mode" what should I do?

If its a flat screen monitor ?

eMachines flat-screen monitors offer high quality at low cost. eMachines flat-screen monitors are compatible with most brands of PCs. Issues with eMachines flat-screen monitors can arise from faulty power sources, cable problems and incompatible settings. These issues can be resolved by testing step-by-step each possible cause.

Plug the computer's power cable firmly into a working AC outlet. Press the computer's power button.

Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

Your new moniter may not be compatible with your computer. I have an Emachines that won't take a flat screen. I have to use a big bulky moniter because it says not connected even thought the hookup fits the back of the tower. That might be your problem. Did your old moniter work correctly?

This means your video card is set to a frequency that is too high for the monitor to match. Lower the switching speed via the properties window on the computer. Try 800x600 @ 60hz for starters. You can reboot into safe mode by pressing and holding F8 as you reboot. This will allow you to boot in a low resolution mode which should allow you access to these settings.

If you can see the windows logo screen both your computer and monitor is working, possible problem could be that the display settings are set to high that your monitor is unable to handle it. Restart computer and keep tapping F8 key. This will take you to the advanced options menu In the list of options here choose enable low resolution mode and hit enter (you can only use your keyboard to choose - use the up / down arrow key) once you enter windows low res mode change it to 800 X 600 and restart the computer Once you are in the right mode now change the display settings accordingly.

Yes. It would be _stupid_ to design a monitor that was compatible only with _some_ brand-name computers.

A little more information about your requirements on assistance may help.

Hi,

It sometimes takes up a minute for video card to detect new moitor. Try attaching new monitor only and boot it in save mode.

It sounds like that monitor has a leakage problem on the ground or shield. This is a common flaw that forces intel motherboards to keep from booting. If you carefully cut the outermost layer of monitor cable away (it looks like a basket weave made of metal threads) that surrounds the other signal cables inside, this problem will go away.

Actually it was quite easy. I rebooted my computer in "safe mode" by restarting it and pressing the F8 key. At the start up windows gives you an option to toggle down to "enable VGA mode" and select it. After that, my computer recognized my monitor and it has worked fine ever since!

Sounds like the LCD mother board is bad. I have the same problem. The board cost $75 at sva-usa.com. I trashed it and bought a use Dell LCD off craigslist for $60.
