I have Dell XPS 8100 and since recently I am unable to adjust my screen resolution. I have googled and some say that this is the case when Video Card fails.
Is it true? And Does someone know how to test the Video Card, to be sure that it not working properly? And if Video Card failed, what is the best alternative to buy?
Thank you for your help...
I am running:
Window 10 Pro | NVIDIA GeForce GTS 240 | Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz | RAM 8GB | Memory 200GB SSD and 2TB
When video cards fail you usually would not have anything on the screen. Explain why and how are you changing the resolution. You cannot change the resolution to an unsupported one. Open Display settings and choose the recommended display resolution. You will not be able to use any higher resolution for a new monitor. The old video card can only go as high as the recommended resolution.
If you bought a fancy new monitor you will be able to use it on your next computer with a better card. The old 8100 does not support today's high resolution video cards.
Thank you for your response .
As you can see in picture I am not able to choose anything. Resolution is fixed to 800×600 and screen is blurred. I didn't had this in the past. I could choose from several options.
I have tried to update driver of Video Card, but is not updating. I didn't succeeded even after the clean installation of Windows 10 Pro.
I hope that it is clear now if you look at the picture.
Would you say that my Video Card not functioning well or is it something else?
PS: screen is working properly when I connect it to my laptop (Dell Inspiron 7000)
Not sure what you mean by the video card driver is not updating. Is there a GTX 260 driver and you tried to update it or was the driver missing and you tried to install a driver. Did you download the video driver for you system from Dell support? When viewing the driver details, Windows 10 is not listed as one of the supported operating systems for Dell video driver for the nVidia GeForce GTX 260. You may want to go to the nVidia website to find a Windows 10 driver.
You could remove the discrete graphics card and try the integrated graphics. In some systems the integrated graphics is disabled if a discrete graphics card is installed.
