Unable to get 2560 X 1440 resolution to work

All we need is an easy explanation of the problem, so here it is.

Problem –

I can’t get 2560×1440 high resolution to work on my Dell 27″ U2713HM Monitor.

Details –

I have a Dell E6520 LAPTOP running 64 bit Windows 8. The highest resolution on the laptop is 1920×1080.

It shows 2 display adapters under Device Manager

  • Intel(R) HD Graphics 3000
  • NVIDIA NVS 4200M

I checked to make sure drivers for both are latest.
In my task tray I have both Intel graphics and NVIDIA managers.

I bought a Dell 27″ U2713HM Monitor to use 2560 X 1440 resolution. Installed the Dell Display manager, latest drivers etc.

Connected monitor using Dual Link DVI through my docking station.

I just cant get the 2560 X 1440 high resolution. It only gives me 1920 X 1080 on the monitor. I even tried the HDMI connection.

Is this because my laptop display card has max resolution of 1920 X 1080?

So in order to use a certain max resolution, the display card in my laptop needs to support it?

If I see 2 display adaptors in Device manager, does it mean I have 2 display cards?

How can I get the Dell 27″ U2713HM Monitor 2560 X 1440 resolution to work?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Both the Intel and Nvidia GPU seem to have a max resolution that is dependent on the connection type.

From Intel Graphics Reference and nVidia the max resolution:

  • Display Port: 2560×1600
  • HDMI/DVI: 1920×1080
  • Analog VGA: 2048×1536

The Intel link is less clear that HDMI and DVI are less than the DisplayPort but there are a number of other sources that claim this (here, here and here).

The specs to your laptop show that it only has HDMI out which appears to be the limiting factor. You would need to have a display port out on your laptop and into your monitor to use the larger resolution.

To answer your other questions:

  • Yes your max resolution will be limited by the max that the video adapters will support.
  • Yes you have two adapters but the OS is supposed to dynamically handle which one is used (see here, here and here)

Method 2

Update to my last post: While the DisplayPort cable didn’t work when connected to my Dell Laptop docking station’s DisplayPort, and while it didn’t work if I connected it to my laptop’s DisplayPort while the laptop was in the docking station, once I removed the laptop from the docking station and connected the cable to the laptop’s DisplayPort and rebooted, VOILA, I finally got full resolution on the Dell Ultrasharp. Hope this helps someone else…it suggests maybe there’s something wrong with the docking station’s DisplayPort. No problem, I’ll just not use it. Once you get the Ultrasharp displaying in full resolution, you will be a Very Happy Camper, so don’t give up until you’ve tried all possible combinations. Good luck; hope this helps someone else!

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
