Workaround for problems with the display resolution in web browsers on a DisplayLink screen

Workaround for problems with the display resolution in web browsers on a DisplayLink screen

I do have a Pluggable HDMI USB display adapter in a Microsoft Surface Pro 3 Tablet with an Intel HD5000 graphics card. The Pluggable device uses a DisplayLink processor and allows the connection of additional displays to your computer or tablet. The second screen in my case runs with Full HD resolution (1920×1080) without any problems. I can use most applications and even videos on the second screen.

But I do have a problem with web browsers, such as Chrome, Firefox or Internet Explorer, on my DisplayLink monitor. Web browsers behave different as they look like running running in a 1024×768 resolution or even worse. The web content isn’t rendered sharply. If you move the browser windows to the first screen, the browser automatically snaps back to regular behavior and a fine HD resolution. Sometimes a reboot helps, but usually the problem comes back after a while.

Pluggable and DisplayLink both wrote articles about a problem similar to this with Windows 7 and a broken Microsoft Windows Update. Other articles propagate to turn off hardware acceleration. But this won’t help. I currently run the recent DisplayLink 7.7 M2 driver release. There are no newer updates available.

I found a nice workaround for this problem: Just mirror the DisplayLink screen to your default HDMI port to show the same output on both screens. The browser will stay in the correct resolution even after switching back to extend to the two screens. Some kind of reset for the corrupted resolution settings seems to happen after this.
