User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.92 Safari/537.36

Steps to reproduce:

Render a fullscreen GeckoView on an Android TV device (Nvidia Shield TV) connected to a 4K/2160p display

Actual results:

The GeckoView is rendered in 1080p, as confirmed by checking window.outerWidth in conjunction with window.devicePixelRatio. This is also confirmed by checking the allocated SurfaceView buffers in the output of adb shell dumpsys SurfaceFlinger.

Expected results:

GeckoView renders at the native resolution of 2160p
