How to fix Windows 7 RDP resolution limit of 3840×2048 on 4K (3840×2160) monitors? (also applicable for Win Server 2008 R2)

One of the issues of Windows 7 (and Windows Server 2008 R2) is related to its inability to support 4K resolutions over RDP. Windows 7 RDP resolution is limited at 3840 x 2048, whereas 4K monitors run at 3840 x 2160, which leaves a small black strip at the top and bottom of the remote desktop window. The following article describes the way I was able to resolve this issue.Make sure Windows 7 (Windows Server 2008 R2) is using RDP 8.1. To check the currently running version of remote desktop, right click on top of the RDP window and select ‘About’ option:

It should show that Remote Desktop Protocol 8.1 is supported:

If you’re not using Remote Desktop Protocol 8.1, first make sure that you’re running Windows 7 SP1 (latest Windows Server 2008 R2) and then go to Microsoft Windows update page at and update your RDP to version 8.1.

Once you’re using RDP 8.1, navigate to the following page: and download Hotfix update that enables support for Ultra HD resolution for RDP sessions in Windows 7 (and Windows Server 2008 R2).

You’ll need to fill your email and Microsoft will send you a link to download, the hotfix request screen will look something like this:

Once you receive a file, unzip it and you’ll end up with a file called: Windows6.1-KB2989007-x64.msu (or something similar for Windows 2008).

Simply install it, reboot your computer and next time you RDP to Windows 7 (or Windows Server 2008 R2) your screen will properly scale to support 4K (3840×2160) resolution.
