Problem with Maximum Resolution DELL U2711 Flat Panel Monitor

Setting the Maximum Resolution

1. Right-click on the desktop and select Properties.
2. Select the Settings tab.
3. Set the screen resolution to 2560 x 1440 (DVI and DisplayPort) or 2048 x 1152 (VGA) or 1080p (HDMI, Component).
4. Click OK.

If you do not see 2560 x 1440 as an option, you may need to update your graphics driver. Depending on your computer, complete one of the following procedures.

If you have a Dell desktop or portable computer:

• Go to support.dell.com, enter your service tag, and download the latest driver for your graphics card.

If you are using a non-Dell computer (portable or desktop):

• Go to the support site for your computer and download the latest graphic drivers.
• Go to your graphics card website and download the latest graphic drivers.

In fact, if I used VGA Cable + USB Cable, the maximum resolution is only 2048x1152. And if I used DVI Cable + USB Cable, the maximum resolution is 1600x1200. I can not use DisplayPort Cable, because my VGA Card NVIDIA GeForce FX 5500 doesn't has DisplayPort input.

DELL U2711 have many input, that are :

• VGA input
• DVI-D 1 input
• DVI-D 2 input
• DisplayPort input
• HDMI input
• Component video input
• Composite video input
