Your monitor does not like the resolution that you have it set at. I have a monitor that does exactly the same thing unless it is set to 1440X900. Check the documentation that came with the monitor, it should tell you what resolution to use. If you cannot find the documentation, reply with the make and model of your monitor and we can find it for you.

To change the resolution of your monitor (in Windows), right click on an empty area of your desktop, select Personalize or Properties, then select Display Settings or Settings (depending XP or Vista).

Change input timing for monitor when i can't do anything


Hi Austin
it sounds as though you have a problem with your graphics card drivers and your tv will not accept the lower resolution. Do you have another screen that you can connect to prove/disprove my theory? If your tv will not accept the lower resolution input then you need another screen to enable you to sort it out. Hope this is helpful.

My computer comes on and a analog shows up and my screen turns blank


Is it a desktop computer? If it is, check the video cable in the back of the monitor, a blue video cable means analog input and a white video cable means it's a digital input. You may have a digital input and all you need is to press the button on the monitor that has a little monitor symbol and see if it switches input types. If you have the blue cable connected to the monitor and you still get no signal then you may have a bad video card.

When i put pc on this message comes up on screen saying input not supported and it floats round in a little box.


Hello,
This generally means you have the display resolution set higher then the monitor can support. To fix this press F8 after you turn the computer on. You may have to press it a couple times before the windows loading screen. A black menu will come up. Select safe mode. Your PC will load into safe mode with minimal drivers and settings. Go to the control panel and select display. Change your screen resolution to something lower then the setting is is at right now. If your screen is 19" or smaller try a setting of 1024x768 for starters. If its 20" or higher try 1280x1024 for starters.
Regards, Chris

When using computer for about 10 min, monitor goes blank with an error message of"No Input Signal" then computer rebuts several times. Any idea's?


Its possible that your computer maybe having a driver conflicting with your monitor. My suggestion would be reinstall the software that came with your monitor. If you don't have that go to the companies website that produced the monitor and download the newest monitor drivers.
As well for an extra double check, make sure that all wires connected to the monitor and the computer are in place.
(might check your monitors energy saving setting)

Boot up computer. Nothing comes up on screen. Get a message:"information. No input signal." Everything is plugged in correctly.


  • check the cable on the monitor screen
  • if after removing the data cable from the computer and it has no vertical color screen then
  • try other data cable
  • try other monitor screen

Monitor says no input signal


Do the icons look ok when you can see them? It sounds like your resolution may be way too high for the monitor. It loses sync and blanks the screen rather than show a lot of mess.

Boot your windows in safe mode (tap F8 before it gives you the progress bar.. just keep tapping it until you get a boot menu)

Everything should look big, but the monitor shouldn't cut out. Go to your display properties and set it to the lowest setting. (even if you can't move the slider, just click it once) Then OK and restart.

If that works, you should be in normal Windows with a horrible resolution. Go back to display settings and set it ONE STEP higher. Apply and have a look. If it's good, go another step, and repeat.

My desktop is not centered and the fonts are too big. Also my Start button and bottom toolbar have disappeared.


Sounds like your resolution has been set too low.

Firstly, i'm going to assume you have a 17" LCD monitor, and that you are running Windows XP. (what a guess!) =-]

Generally, you'd want to right-click the desktop in a blank area, select properties. This gives you the display properties. Go to the last tab across called "settings", then under "screen resolution", drag the slider up a notch and hit apply. If it looks right, leave it at that. If it's not quite right, go another notch and apply. Keep going until you have it right.

But on your 17" LCD monitor, running the DVI cable to the PC... the computer should already have detected it's maximum resolution. In this case, you can drag the slider all the way to the right and hit apply, knowing that this is the optimal resolution. Also on your Dell LCD, you should have several buttons for adjusting the screen. One of those buttons is usually a "self-adjust" or "auto detect" or "some other obvious thing" for self-adjusting the screen viewable area. It *should* do this automatically when you change resolutions, which your Dell 173FPb should do anyway. =-]
