Toughbook CF-19, docking station (port replicator) CF-WEB184, Ubuntu 19.04 – external VGA and 1920×1080 1080p resolution

Today I mounted my Toughbook CF-19 port replicator, model WEB184.

I’m using it mounted on wall, with disabled built in screen, only using my TV as main display in 1080p resolution.

While i was using VGA port on Toughbook CF-19 i had no problem in setting up 1080p resolution, but after using port replicator, maximal allowed to select resolution was 1024px !

Here is how i mannaged to get proper resolution

sudo cvt 1920 1080 60

This command will display calculated data for Your screen called newmode, copy it and paste in bellow code

Create new sh file, and add +x execution

!/bin/bash
xrandr –newmode “1920x1080_60.00” 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr –addmode VGA-1 1920x1080_60.00
xrandr –output VGA-1 –mode 1920x1080_60.00

You can add this script to Your desktop or menu, click it while being docked and it change resolution to 1080p

Hiroyasu HI-R23 – make Zello fit screen

Hiroyasu HI-R23 – BUDGET Zello PoC 4G LTE Walkie Talkie – making it more civilized by changing system font size. God know why it’s not delivered with smallest possible font! Default setting make Zello “unusable” – thankfully couple clicks make it “fine”. Connect via degular micro USB cable and execute

"adb shell am start -a android.settings.SETTINGS"

then navigate to “display” and change font size.

I recommend use also “total control” and connect to WiFi and Zello using computer keyboard… most like You do it only once… why not help Yourself?
