My ET1161 computer won't recognize my monitor how can i find out whats wrong?

Shut down compter, unplug router and the ISP modem, Check ALL cables and reseat ALL connections, plug in the ISP modem allow it to selftest, plug in the router allow it to selftest. Reboot the computer, plug in Ethernet cable.You didn't give much info to work with. Wired? Wireless? Does it connect to other devices? What is the OS? Vista? Is this a recent issue? What it the router Make ,Model? Open the Network and Sharing Center, Manage Network Connections, Is the Ethernet Adapter enabled?

check the vga cable which get loose connection then the signal from pc not recognized.

if no signal that was mean no source being recognized. tried to hooked up with other monitor or pc just to ensure if the problem is with in the monitor. by the way have you been tried already replaced the vga cable?.if not yet tried to replaced the cable .

There is something else wrong like bad RAM, or a failed CPU fan. Open it. Turn on and verify the CPU fan is running. If not fix the fan immediately before the CPU fry's.

This is typical when there is no communication with video card. Test on another PC. Re-seat video card on PC. Use VGA cable instead of HDMI or DVI. Make sure monitor is correct mode. Again VGA, DVI, or HDMI, depending on cable used.

A camera that works connected to a TV without software is not the proper device to connect to a computer. Check again with your packaging and instructions.
Having a camera working on the computer and then porting the video signal to a TV monitor is the preferred arrangement.
Install the software, reboot, then connect a PC camera, it should be recognized and be testable on Skype, etc.

What you'll need to do is set your TV to whatever input you're using on the laptop (VGA or HDMI). Then go into Display Properties, which can be found in Control Panel. Select the grayed out 2nd display and check "Extend desktop onto this monitor". Slide the resolution to something your TV can support such as 1366x768 or 1920x1080. Apply, OK, OK and you're done. The exact steps that you'll need is slightly different than the instructions here because of variation in TVs and OSes, but it's mostly identical.

The F4 button on laptops usually controls the second monitor. Try plugging it in and holding F and press F4.

I would go ahead and boot into safe mode where you say it does work and then take a look. See how it detected it...ie look in device manager and see if it picked it up by it's true brand/type etc. Check the settings both of the display and on the envision itself. Check the resolution selection. It's probably picking it up as a lower res. but when it boots into reg windows may be trying to run at full res and perhaps that's what it won't do. Check to see what driver it's using. It may need the specific driver from envision and not the generic driver. It could also be a bad pin on the envision itself.

If you have another computer you can hook it up to, do that to make sure the envision is working. That way you can deduce which is the problem, the monitor or the setup in your laptop.

This may be something that Windows (or the computer is telling Windows) to do. Everyone wants to reduce the power consumption in the computer, so be default your monitor may be going into 'sleep' mode and turning off.
1) To change this, RIGHT click on the Windows desktop. 2) When the menu appears, select PROPERTIES, then select the SCREEN SAVER tab. 3) There are 2 things to check here. First at the top, make sure that your screen saver is selecting something beside BLANK. This will cause the monitor to blank out and appear to have turned off. 4) The second thing to check is the POWER settings. Click the POWER button at the bottom on the screen. 5) Now, you will see 2 rows of power options, one for when the computer is plugged in (which is all the time with your desktop) and the other is when on batteries. We're concerned with the PLUGGED IN settings. 6) Make sure the TURN OFF MONITOR setting is set for NEVER. This will ensure that your monitor never turns off on you. 7) Now click OK and OK and now your monitor shouldn't turn off on you.
Hope this response helps you out.
Best of luck!
