To help you troubleshoot the monitor 'No Signal' issue, please find the steps given below:
- Turn off your computer.
- Unplug the cable running from your monitor to your PC and plug it back in, making sure the connection is firm. The most common cause of this error is a loose cable.
- Re-attach the cable running from your monitor to your PC. If the monitor is still not displaying a signal after firmly reattaching the cable, the problem could lie with the cable, especially if the cable has visible damage.
- Replace your monitor with another monitor if possible. If the 'No Signal' error still appears, the problem does not rest with the cables or the monitor, but with your PC.
- Open your PC case and locate your video card. Remove the card and then replace it firmly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the monitor. Close your PC case and test the monitor again.
- Replace your video card completely. Your video card may suffer from internal damage that is not allowing it to output a signal.
If issue persists, it is recommended to contact your monitor manufacturer for further assistance.
This sounds as if your video card is not seated. Your vidoe card is where the monitor connect to the tower. If you can open the tower locate the video card and check to see that it is seated in the slot firmly. Mkae sure to diconnect the power supply before opening the tower.
Hello figment_of_u, DVI stands for Digital Video Interface. They are used for direct digital connections between
source video (namely, video cards) and LCD monitors. This provides a faster, higher-quality image
than with analog, due to the nature of the digital format.
All video cards initially produce a digital video signal, which
is converted into analog at the VGA output. The analog signal
travels to the monitor and is re-converted to a digital
signal. DVI-D eliminates the analog conversion process and
improves the connection between source and display.
Hope this helps you understand what DVI is for. Thank you for choosing Fixya.
If the screen is connected to a computer usually its a video card/ video cable problem and not the LCD monitor. Try to check the video cable look for loose connection or bent pins, if none try using a different video cable or checked the video card component of the computer too see if its still working,. Your monitor is dependent to your video card signal inside the computer. Without the signal monitor will not work.
thanks for using Fixya
The monitor is not detecting a signal from your video output. The video circuit may be blown. If it is a plug in card, try re-seating the card in the slot. Make sure your cable is seated good and there are no problems with it. If you have another monitor, you might try it. If the video circuit is part of the mother board you may have to get a new one. If not on maintenance, you could try buying a plug in video card. May have to reset your BIOS settings to let the system know you are switching to a plug in card. Also, your monitor could be having a problem.
you will need to update a new driver for the monitor
if it's too old you will need a new video card thats compatible with the new monitor.Which i think your brtter off doing.

is discontinued and the quality of video is weak.if you needs the crt specification i will post it for you.thanks.
First of all I would check your video card. Do you have another monitor that works fine? If so I would hook the good monitor to your video card and see if you are getting a signal. If you still do not have a signal in the good monitor there is something wrong with your connection on your video card. Check the connector on your video card if it wiggles alot then it has come loose from the card. Best option here is to buy a new video card. If you feel that the connector is seated flush and does not move. Then you might want to look at two things. Either your monitor is not working properly or there maybe a piece of hardware that has come loose or unseated in your computer case. Try this and if you have problems feel free to contact me.
