Try connecting the NEC to a different computer, to see if it correctly accepts 1280-by-1024.
If so, then there's nothing wrong with the monitor, and the fault lies with either the video-adapter in your computer, or something messed-up with your installed copy of Windows.
Try replacing the video-adapter.
The 920WM has a recommended resolution of 1440x900. If your display properties are set to a higher or lower resolution, there will be ugly effects on videos, photos and fine text.
If you're running WindowsXP, minimize your apps and web browser so you can see the background. Right-click on the background and select "Properties" to bring up the display properties dialog. In that dialog, select the "Settings" tab to see the display resolution. Set that to 1440x900 if it's not already, then hit "OK"
If videos are still blotchy, then check the video playback software to make sure it's not setting it's own resolution.
If that helps, please be sure to hit the "thumbs-up" button for me.
If not, use "add comment" to fill in some more details (XP or Vista? What's the video playback software called? How are you viewing pictures?) and I'll do my best to help!
The RAM module/s may be faulty or needs reseating because the video card grabs some of the system RAM. If you got two RAM modules then swap them around in the DIMM slots.
Try deleting/disable the video driver or change it to standard VGA.
If you can uninstall the video driver then OK.
Reboot the laptop and reinstall the video driver and it usually requires a reboot for the driver to take effect.
Also try connecting an external monitor to the laptop's external video port, power up the monitor first then the laptop. The video should automatically divert to the external monitor. Then try and change the screen resolution. If this doesn't work then there is a possibility the Video card might be faulty.
As a last resort reinstall Windows it may fix your problem.
In Safe Mode, your monitor will not be listed as it is using a generic device driver for basic display. Go into your video settings and reset it to the lowest resolution available. Reboot the computer into Vista again and your display should be working. If you check Device Manager now, you should see your monitor listed. If it isn't, you will need to load the Vista drivers for it. You can then modify your display settings to suit your preferences.
the resolution setting may have been in inadvertently change to one that your monitor does not support you mentioned that you have another monitor that does work with your computer what i would do is to set the video resolution to the lowest possible setting and the turn off the computer and connect the questionable monitor to your computer and reboot if it does come up then you will be able to make changes and find an appropriate resolution for your monitor
Try these 2 steps if they don't work get back to me :)
Step 1. Connect the video cable and turn on the computer. What happens?
the monitor screen remains blank (no startup screens or onscreen
display messages), the monitor must be connected to another computer
using a different cable to determine if the monitor is bad. Skip to the
Step to connect the monitor to another computer.
If the monitor is capable of displaying boot screens but is unable to
display Windows, use the following steps to set the computer to a
the native display resolution for your monitor in the User Manual or in
the product specifications for the monitor model. If you are unable to
find the native display resolution for your monitor model, temporarily
use 1024x768 for troubleshooting purposes.
Turn on the computer and press the
key repeatedly when the first startup screen appears.
If you are using Windows Vista, select
Enable low resolution video (640 x 480)
, and wait until Windows opens. To set display settings that match the monitor, use the steps in the HP support document,
Changing Display Settings, Background Image, and Screen Saver in Windows Vista
If you are using Windows XP, select
Enable VGA Mode
, and wait until Windows opens. Continue using these steps to set display resolution.
If you are using Windows 98 or ME, select
and perform the following steps to enter into a standard VGA mode:
Once Windows opens to the desktop in Safe Mode, click
In the Open field type
The MS Configuration Utility window appears.
button, and select
VGA 640 x 480 x 16
if it is available.
and restart the computer.
After Windows opens, click
, and then click
In the Open field type
button, and remove the checkmark next to
VGA 640 x 480 x 16
. Do NOT restart the computer.
After Windows opens, right-click on an open area of the desktop and select
(Windows XP, 98/Me) or
In Windows Vista, Scroll down and click
In Windows XP, 98, or Me, click the
In Windows Vista, select the native display resolution size using the Resolution slider. Set Colors to
Highest (32 bit)
In Windows XP, select the native display resolution size using the Screen resolution slider. Set Color Quality to
Highest (32 bit)
In Windows 98 or Me, select the native display resolution size using the Screen Area slider. Set Colors to
after you have made your adjustment.
The screen should blank out temporarily and come back.
If you are satisfied with the new display settings, click
on the Monitor Settings windows. If you are not satisfied or if the
screen just goes black, wait: Windows sets the screen back to the way
it was before. Try another setting until you find a display
configuration that is compatible with the monitor and meets your needs.
the native resolution is not available, download and install updated
video driver software for your computer. Updating the video driver
software can add more resolutions (graphics modes).
Restart the computer. The monitor should now display a full screen image in high quality. You are done.
Step 2: Connect to another monitor
a different cable, connect the monitor to another computer that has
video. Turn on the monitor and the newly connected computer. What
the monitor works, the video hardware on the original computer is
likely to be the source of the problems. You can try connecting the
original computer to another monitor that works to update its video
If the monitor remains blank, repair or replace the monitor.
You will need to change the display settings for the type of lcd monitor you have, it is a wide screen I am assuming, you can change this by right clicking on the desktop select properties then settings the screen resolution should be on the middle left side and change this until you get a screen that you like There is also an advanced setting then select monitor at the top tab and change to refresh rate to the lowest setting (60 hz) this should get the HCL monitor up then change the setting until they dont work the operating system will revert to the previous settings if you cant see anything after a change. you may also need to use the automated setup on the lcd monitor select auto from the menu (osd). Now if you can not do this on the HCL lcd you may need to use that other Samsung monitor and then set up on that at the lowest resolution so that the lcd can be changed with a working screen. Lastly you may need to uninstall the samsung monitor drivers if you installed those, and leave the generic drivers in for the monitor (plug and play monitor). I am making some guesses here as you did not tell me if the 1st Samsung monitor was a lcd also , and if the second HCL monitor is a wide screen etc what type of operating system are you running is also important 98 is fussy and 2000 is much more simplified as is XP , vista would be garbage (if you could get it to run on a pIII), As for reasons for resolution problems, way too many variables to discuss in a short answer forum like this, sufficed to say that the resolution is different because in the past there were lower resolution (less pixels) on monitors, the refresh rates were different by manufacturers and the way the lines were scanned could be different, so setup of the monitor with the video card was also very important interlacing etc was also handled differently until that industry decided on a common standard. I hope this helps you to get the monitor up and running.
i think you have problem with your graphics card. restart your computer and then before starting to windows press F8 to set your settings to safe mood, after booting up to windows restart the system again.if the problem persist reinstall the software drive of your graphics card if you have it.
