I have a Lenovo Thinkpad T410 and an LG monitor E2250 (1080p, so should support 1920×1080). I try to connect the monitor using the RGB connector and use it as an external monitor. The problem is that Windows 7 only shows the monitor as a non PNP monitor and will not allow me to set the resolution to 1650X1050. I installed the driver for the monitor manually, but it still did not help, even after a restart.

I might add that the external monitor does not display the BIOS messages at boot.

What can I do?

Are you sure the laptop supports an external monitor of that resolution? – RJFalconer Nov 9 '10 at 22:58
@RJFalconer - It's a Thinkpad. It supports that resolution. (VGA does go that high, right?) – Shinrai Nov 10 '10 at 15:37
wikipedia says VGA should support 1280x1024px @85 Hz (160 MHz) and up to 2048x1536px @85 Hz (388 MHz). Try updating graphics drivers perhaps? – RJFalconer Nov 12 '10 at 0:39
I checked for a driver update and got the message that I am using the latest version. I think I am just going to buy an HDMI cable and be done with that. – Shaihi Nov 12 '10 at 14:40

I ended up adding a custom resolution through the NVIDIA controller for the card. Using the native resolution for the screen works without problem (1920x1080).

If this solved your problems, you should accept is as the correct answer. – AndrejaKo Nov 17 '10 at 21:54
I'm experiencing the same problem but I do not know which values to insert in the control panel. Can you help me? It's concerning the last image!… – Bram Vanroy Dec 28 '12 at 13:53
Sorry, I am no longer in possession of that computer and don't remember any values I used.... – Shaihi Dec 29 '12 at 20:04

I had the same problem with the LG E2250-v monitor with an Acer notebook running Win7 Pro 64-bit. Win7 Dsisplay settings is a no-go. I finally installed a Graphics Controller (I had Intel Card in the notebook) and in the Intel Graphics and Meia Control Panel (taskbar right side bottom corner) I could adjust resolution. Forget about the Display settings in Windows 7, it just does not work. Install or go to your installed graphics card controller. It should work properly.
