Can't get my Dell Precision M50 Laptop video to fill the screen at 1024 768 resolution. Video will only fill the screen when I set resolution to 1600 1200. Is there something wrong with my video card?

try to look this site since dont have idea about ur system

do you have already installed the software of your video card???try to update your video card..

sometimes there are video card that are xp supported that's why when you format your pc the video card is ready to use but it is not updated....

try updating it...then check if you can change the resolution of your pc..

hello, it seems like the only thing you haven't tried is to reset BIOS by taking out the battery from the board. since you have reseated everthing else i am assuming that you are comforatble opening up you laptop.
open it one more time and remove the battery from the board (some of these batteries are now soldered so you may need soldering iron)and leave it out for about atleast 10mins.

see if that helps.

remove external peripherals. remove battery. use ac adapter alone. check if ac adapter has sufficient power or check if ac adapter led is solid green or blue. if not then ac adapter might not giving laptop enough power to power up.
if ac adapter led stays on but some problem check the ac adapter - laptop pin socket if loose or damage. if not then replace mobo.

try this press and hold Fn then tap on arrow up key check if the display will become bright. if fails try connecting an external monitor to your laptop check if display is fine. if not then uninstall video driver then install a latest one. if fails replace the video card drive or motherboard if video is built-in. if display is fine from the external monitor then reseat the LCD cable if fails then replace the LCD panel with the LCD cable.

Go to Control Panel - Display - Settings - Advance - Monitor Tab change Monitor Type to Generic Television click Apply

Try reseating the processor. Go to Dell.com and download repair manual. I have seen this same 3 lights a couple of times on c840's (same machine) when I forgot to lock the processor cam in place...

1.The resolution 1600*1200 is very good. why you need it 1920*1200 ?
2. What kind of samsung monitor do you have ? If is it LCD ... It doesn't suport that resolution ..... Mine, for example, 720N , suports only 1280/1024 . 17" .

Hi!

you cant change the resolution? did you check the video card driver in device manager? check if the driver is installed properly. if not, then download the latest video driver at support.dell.com > go to drivers and downloads and select your system. If the video driver is okay, then download the latest BIOS upgrade in the same site. post back here if the issue persists.

Hope this helps!

The type of screen you have is a UXGA screen. the optimal resolution for that is 1600 x 1200. changing the resolution for that will distort the screen causing black borders. If a computer has a 15.0+" SXGA+ screen with an optimized resolution of 1400x1050 and the screen's current resolution is set to 1280x1024 pixels, the display will shrink resulting in a black border surrounding the edges of the screen. Also, all other lower resolutions may be stretched to fit the screen. No border will be visible, but fonts may appear slightly fuzzy.
