Re: Input Signal Out Of Range

Some monitors have low resolution, that if it doesn't support that resolution then you'll expect an "input signal out of range" message on screen. try to boot on "safe mode" if it works then you have to lower your screen resolution at "display properties" if not then the monitor has a defective data cable. ;)

Re: Input Signal Out Of Range

All you have to do I think is adjust the monitor video card refresh rate from 85 to like 75 and it should work for you.

Re: Input Signal Out Of Range

Input out of range means only that refresh rate must be changed ... if u don't get windows menu or boot in windows and change refresh rate , please turn computer off (and power cord) then switch jumper CLcmos or remove bios battery and then connect it back in place. Then as windows starts POST hit delete for bios , if bios have load optimal defaults please load , and then save an exit. and your gpu's settings are restarted. This applies for PCI based graphic cards and NOT integrated ones !

You will need to set the signal to a lower resolution supported by the monitor. If you are running Windows, you will need to boot into "Safe Mode" to make the adjustment.

Input error

If you are getting the no input or out of range message on your screen then you will need to do one of the following:

No input
If you aren't getting signal then it means that your graphics card has failed. Make sure the video connectors are secure. If all connectors are in place and you still don't get a signal then you will need to:
Connect the video cable to onboard graphics if you were using a graphics card. If you're not using a graphics card then it means that your motherboard vgraphics has become faulty. You will need to consult a repair technition.

Out of range message
If you are getting this message then you will ned to change the refresh rate on your monitor. To do this boot your computer into safe mode by pressing F5 during boot up. Then right click on your desktop and click on properties. Then click on the Settings tab and click Advanced. Once in the Advanced settings click on the Monitor tab. Then all you will need to do is set the refresh rate down to a lower setting like 60 Hertz.

I changed some setting for the computer resolution and now my monitor just says no input signal..the hard drive turns on and then goes into sleep mode and says no input signal. How can i fix this problem?

Possible reason is that input signal goes out of range that probably a Screen refresh rate that the monitor cannot handle. Instead of bursting into flames, the monitor shuts itself
down as a protection feature. Look at the monitor manual if you got one.

Safe Mode should allow the monitor to work in the problem account.

Try this.

Boot in Safe Mode (see below)
Switch users to the problem account
Right click the desktop
Select Properties
Click the Settings tab
Click the Advanced button
Click the Monitor tab
Select: Hide modes that this monitor cannot display
Select a different Screen refresh rate
Click Apply twice and then Click OK

Or try this:-
power on the system and press and hold F5.
When a screen appers with some option, try to find a option something realted with VGA setting.
Click that option and let pc start normally.
It will surely work

Input signal out of problem...hp w1707

your video card setting may not be compatible with your monitor's capability. you may need to reduce the screen resolution. you need to boot up on safe mode to change this or use another monitor for a while and try to adjust the screen resolution.

Using a HP L1506 Monitor on a HP Pavilions a 867c computer and has worked, but now receiving "VGA input: no input signal" with window on monitor, followed by "Monitor going to Sleep" and it does. Worked...

First of all, boot your system without the monitor connected to it and when you feel that it's booted upto logon screen (or if you haven't assign password it'll directly logon to the desktop, power on the speaker to make sure you can know it's done) connect the monitor. If this isn't successful, please turn off the system and remove the cmos battery, leave it outside for few minutes and again reinstall it. Boot again normally. Still having the same problem? then let's try another method. Did you see the bios loading (black screen with white text during startup) when you power on the system? If so, press F8 several times while it is booting and select "Safe Mode" and restore your system to previous state. Do let me know if this isn't possible. Good luck Thanks for using FixYa.

Input signal out of range

Did you mean "out of range". Try reloading video drivers. If that doesn't work, perhaps screen cannot use that resolution.

Input Signal Out of Range

I have been having the same problem with my hpvs17 monitor when i start to use my web browser on linux distros. Now, for the next few days i am going to try my system on a regular crt monitor. if the monitor does not crash, than i will have to say that the hpvs17 monitor has a defect.It seems that when i go online, while i am in the middle of searching something, the monitor just shuts off and i get "input signal out of range".

some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.
