I use Ubuntu 18.04 and install scrcpy by snap

[rom1v]

See #932

[deeplee]

I think this is different of #932

I Use dumpstate see display info is

DisplayDevice: Built-in Screen
   type=0, hwcId=0, layerStack=0, (1920x 720), ANativeWindow=0x7b83e23010 (8:8:8:8), orient= 0 (type=00000000), flips=31212, isSecure=1, powerMode=2, activeConfig=0, numLayers=2
   v:[0,0,1920,720], f:[0,0,1920,720], s:[0,0,1920,720],transform:[[1.000,0.000,-0.000][0.000,1.000,-0.000][0.000,0.000,1.000]]

and I can get display info like this

DisplayManager dm = (DisplayManager) getSystemService(Context.DISPLAY_SERVICE);
Display dp = dm.getDisplay(Display.DEFAULT_DISPLAY);
Log.d(TAG, "getDisplayInfo: " + dp.getWidth() + "x" + dp.getHeight());

and output

 getDisplayInfo: 1920x720
