My Insignia Monitor doesn't work with my laptop, I've tried everything, from pc settings to cables, etc, i only receive a NO SIGNAL ad


Usually you have to toggle the display output on the laptop. The FN key + one of the F# keys with a monitor icon on it. Toggle it until it outputs to the monitor. Your getting "no signal" because no signal is being sent to the monitor or you have the monitor on the wrong input if it has multiple inputs.

What should I do because it says no signal input


Sounds like your video card or monitor is bad. Most likely it's the video card because if it was the monitor the No Signal Input could not appear on the screen. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed Monitor displays ok without a problem then your original monitor is bad. If the Borrowed monitor has the same issue of No Input Signal as your original monitor, then your video card inside the computer is bad.

I have HCL Ezeebee desktop computer when we boot the system monitor, keyboard, mouse blink for a while and monitor (HCL) show 'no signal' message, and keyboard num lock led not display mouse i


No signal at the monitor indicates (if you know the monitor is working ok) a failure of the graphics chip or graphics card, The lack of indicator light on the num lock LED and the lack of power to the mouse would indicate that there is a major issue with the motherboard.
you can try using another monitor to confirm the problem lies with the graphics, and in the case of the keyboard and mouse, swap them for a usb version, if they work, the Ps2 ports are probably damaged.
I'd be thinking of replacing the motherboard

Samsung syncmaster 275t won't start - what to do?


The Samsung monitor is okay, the problem is a compatability issue between the laptop and monitor. The VGA toDVI is the problem you are converting a analog signal to digital, the signal level degrades when that is attempted. If I understand this the laptop puts out the analog signal "VGA" and the monitor has the DVI input, "digital" The only other suggestion is turn off the laptop screen to see if the monitor will work.

What's your problem?


First, make sure this isn't coming from your signal source; these items are not listed in any of the functions described in the manual for your monitor.
If disconnecting, changing or turning off your signal source doesn't get rid of the control item display, try resetting the monitor (maybe the display has some extra firmware features not in the documentation):
  1. Press the Menu button on the side of the monitor.
  2. From the On-Screen Display, navigate to the Setup&Reset menu using the arrow buttons, then press the Source/Select button.
  3. Navigate to "Reset" and select it.
This should restore everything to the factory default setting and get the TV/monitor out of whatever mode it's in.

This may sound ridiculous, but I recently spent two weeks troubleshooting a monitor that wouldn't display properly. Turns out it wasn't plugged in all the way. Make sure that it is plugged in properly, and that your computer/device is displaying TO that monitor.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:


Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.


Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

My vs19 monitor will not come on. says vga input/ no input signals and then goes to sleep. I checked all connections and all are ok. Happened about 2 months ago but has worked fine since. Is there a way...


It's not your monitor. It's your computer.
If you see a display on the monitor, it means it's working. (and you do)
Your computer is not sending a signal to the monitor. If you are working with a laptop, you can just press the Fn key/special function key combo to send the signal to the external monitor.
If you are using a desktop, then you need to do some troubleshooting.
