after using my westinghouse LCM-24w1 LCD flat-panel widescreen for at least a year on windows 7 pro 32-bit without difficulty at it's native 1920x1200 resolution, I now have an inch wide black stripe down the right side of the screen. the windows desktop ends at the start of the black bar. I've tried a PCI Express ATI video card, the mobo-integrated ATI video chip and an nvidia PCI Express video card -- all with updated drivers. they all exhibit the same problem -- windows thinks the display is an analog CRT. both ATI cards and the Nvidia card identify the monitor as an analog CRT. the monitor settings are fine. playing with the horizontal control just moves the image to the right, exposing a black stripe to the left. putting the monitor on an xp pro machine with the ATI card from the win 7 pro pc exhibits normal full-screen function. switching to that pc's integrated graphics does the same. how do I fix this so that the native 1920x1200 fills the entire screen like it used to? does windows misidentification of the monitor have anything to do with it?

The reason these cards are identifying the monitor is analog is because you are using a VGA (analog) cable instead of a digital cable like HDMI or DVI. This is normal behavior. 1920x1200 should work regardless whether you use an analog cable or a digital cable. If it really is using that resolution but not filling the screen you would expect to see everything displayed as if it were very tall and skinny. If that is the case, then changing the horizontal width should correct the problem. This can be done by using the controls on the monitor itself. Incidentally, you want to change the horizontal width (not move the display horizontally).

thanks for the reply. understood on the VGA cable/analog ID. unfortunately, there is no horizontal width control on this monitor -- only horizontal positioning. yes, everything displayed is just slightly squished. circles are ovals stretched top and bottom, etc... but only a little bit. the black bar is more annoying than the squish.

Hi, Thanks for posting in Microsoft TechNet forums. I recommend you change the screen resolution manually by modifying the registry. Please back up the registry firstly. Follow these steps: Click on Start, then Run Type in regedit in the Open box, then hit [Enter] Expand down to HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr ol\VIDEO\{Hexadecimal number for your primary video card}\0000 Note: Under VIDEO will be one or more registry keys that have a long hexadecimal number; this is the Hexidecimal number assigned to a specific physical or logical video card. There may be more than one if video cards have been changed or a major driver update has been performed. The key that has the current setting should be the one that needs to be modified. Double-click DefautlSettings.XResolution, change the Base from Hexadecimal to Decimal notation, and set the X axis. Double-click DefautlSettings.YResolution, change the Base from Hexadecimal to Decimal notation, and set the Y axis. Reboot Note: If settings did not take effect, modify a different video card in the registry Note: If monitor ceases to function upon Windows coming up, reboot and go to Safe Mode. Pull up the registry and change the settings that were last modified back to the way it was or change the resolution to a safe resolution such as 640x480.

thanks for the reply. unfortunately, the "HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr ol\VIDEO" key is empty. all it has in it is: (Default) REG_SZ (value not set) can you tell me what is supposed to be there so I can enter it, then change it? thanks...

Hi, Did you install the video card driver? Under the HKEY_CURRENT_CONFIG\System\CurrentControlSet\VIDEO\, it should be the hexadecimal number for your primary video card. I recommend you install the video card driver again and reboot to see if it works. In addition, please provide us with a screenshot for troubleshooting. You can upload it using SkyDrive.

HI, The nVidia control panel has a scaling feature which should return the display to full screen. Try the nVidia card again. Adjust desktop size and positon. Also, have you tried changing the monitor settings with the monitor controls. Source, change it to a different mode and change it back.

hi, sorry for the delay. work is killing me... I've not yet solved this. I downloaded the most recent nvidia drivers and installed them, but I still see no entry for the card in the registry. "HKEY_CURRENT_CONFIG\System\CurrentControlSet\Contr ol\VIDEO" still has only "(Default) REG_SZ (value not set)" indicated. I'm sorta getting used to having the black bar there -- it's a big monitor -- but I'd still like to make it right...

The most recent drivers are 260.99 WHQL from nVidia- http://www.nvidia.com/object/win7-winvista-32bit-260.99-whql-driver.html I only find settings in HKEY_LOCAL_MACHINE>HARDWARE>DEVICE MAP>VIDEO . The object hexidecimal has no reference to x and y axis. Try the new driver, then power the monitor off and on while the computer is running. You should be able to adjust the scaling with the advanced view in the nVidia control panel.

don't pay attention to the driver indicated in the pic. I've since updated to 260.99. still no entry in the registry, and no scaling options available in the nvidia control panel. I can only move the image, not scale it. the monitor's native controls have no impact as well other than moving the image.

Oh, that was the wizard of OZ driver. There are scaling options. Right-click the desktop and select nVidia control panel. You must expand the display category and select adjust desktop size and position. Did you ever boot to safe mode and uninstall the driver for the PnP monitor in device manager and reboot? Depending on your model there is a 4:3 - 16:9 button or an Aspect ratio in the OSD menu. Those don't help? Are you adapting a DVI to VGA or is it VGA to VGA? Westinghouse recommends adapting DVI to HDMI if your monitor has an HDMI port.

there are NO SCALING OPTIONS available in NVCP on my system. I will post a screenshot when I get back to that computer. to your other questions: yes I did, no they don't, and DVI to VGA. trying DVI to HDMI, picture quality took a royal dump -- like I was feeding the signal to an SDTV set...

ok, I surrender. Windows 7 doesn't like your monitor.

So lets do this, lets take it step by step Verify if the issue reproduces with the standard VGA driver. You can use msconfig -> boot -> basevideo to force VGA driver You can also see what happens in safe mode Also have you already tried completely uninstalling the monitor and adapter driver from device manager? I understand you have tested the monitor on another box and it worked fine. While it is not always practical, do you have the option to test with another monitor? This will tell us if the PC h/w is absolutely fine or not, though this being a h/w issue is relatively small. Also to ensure that this is a OS issue, you can boot up with a Win7 CD or another PE disk and check One thing to note is that on Windows 7, on some video cards (including Nvidia and ATI), if not set the to the recommended resolution there will be black frame appear on the monitor. e.g. NV G100,ATI HD4530 on L194WT LCD which recommend resolution is 1440x900, the display cannot be full screen on 800x600,1024x768,1152x864,1280x720 etc. A black frame will occur. By default, non-native resolutions on a WDDM 1.1 driver use a resolution where the content is stretched, preserving aspect ratio until it is full height of full width. This leaves black bands on two edges if the resolution requested has a different aspect ratio from the native resolution.

BTW the VIDEO key being blank does not look good to me. Sumesh P - Microsoft Online Community Support

thanks, I will try all this over the weekend and report back next week... ...joe

any luck with these suggestions?Sumesh P - Microsoft Online Community Support

Verify if the issue reproduces with the standard VGA driver. You can use msconfig -> boot -> basevideo to force VGA driver --yes it does You can also see what happens in safe mode --no, but safe mode will only go to 1600x1200 Also have you already tried completely uninstalling the monitor and adapter driver from device manager? --yes, a few times I understand you have tested the monitor on another box and it worked fine. While it is not always practical, do you have the option to test with another monitor? This will tell us if the PC h/w is absolutely fine or not, though this being a h/w issue is relatively small. --tried to use my old monitor, and it worked fine, though it's a smaller monitor that runs 1440x900.

Also to ensure that this is a OS issue, you can boot up with a Win7 CD or another PE disk and check One thing to note is that on Windows 7, on some video cards (including Nvidia and ATI), if not set the to the recommended resolution there will be black frame appear on the monitor. e.g. NV G100,ATI HD4530 on L194WT LCD which recommend resolution is 1440x900, the display cannot be full screen on 800x600,1024x768,1152x864,1280x720 etc. A black frame will occur.
