TV PC SCREEN MODE BLANK

old monitor 1280 x 1024
power light on?
OSD work?
if it said on the screen no input sig, then that is 100% true
the PC is not sending output.

check the video cable connections both ends
then if bad, boot PC to safe mode. does that work.
then maybe you set the PC graphic resolution too high for the monitor. use safe mode to set new , legal resolution
1280 x 1024 is max, do not exceed, the horz, vert, reso to the left here. if you do the monitor , will display, out of range. errors.

im confused, you show HP monitor then Sam.
why ?
my guess is HP question posted in SAM section.
so here is my HP answer
1280 x 768 @ 75Hz

if your PC or other device exceeds any of those. this old monitor
will go blank.
HOR, vert and refresh rates max.

to solve this riddle, set the PC to
1280 x 768
then connect monitor and bingo.
but there is a chicken and egg deal here.
if the display car is over this, as most new systems are.
then use safe mode to set the resolution to 1280 x 768
and reboot to normal mode.
boot and it F8 , safemode.

Once you run safe mode. You can turn off the laptop. Then start booting normally.

Check the screen resolution on your computer. If it is set to high, the TV will not be able to display it.

Running XP? Boot the PC in safe mode (hit F8 key while PC is booting up and select safe mode), then set the video resoltuion to 640 x 480, reboot into regular boot up, reset the video resolution to 1280 x 1024 @ 60Hz.

Check to see if this problem follows in safe mode. Reboot and when the Dell splash screen comes up tap F8 until you see the multiboot options. Scroll to "safe Mode with Networking" let the machine boot up and see if you have a screen. If you do, right click on the desktop and set the resolution to 800 X600 and reboot normally. Usually when a screen goes blank in normal mode but shows up in safe mode means you have an incompatible resolution for the monitor or graphics adapter. This may be a driver issue or hardware. If the screen boots up in normal mode at the lower resolution, then try and go to properties again and bump the resolution up a bit, if it blanks again, try to go online and update the driver for the graphics chip.

Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

Do you mean after windows has booted you have a blank screen?
Boot into windows in safe mode (by pressing F8) during the boot up process.
When booted go into device manager and remove any video drivers under display adapters, if it asks to delete the files as well answer yes.
Reboot into normal mode and let windows find the driver for you.

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Does it go blank before you signon, or when you sign on? If before boot to SAFE MODE and check the video display settings.. you man have settings your monitor can't understand.
If that doesn't work and you get to input your signon and then it goes blank you most likly have a virus or malware.
Log into safe mode, and use SYSTEM RESTORE to a time before you stated having the problem.
Start - All Programs - Accessories - System Tools - System Restore

It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard? Ray
