Hello, I am trying to connect a laptop to the TV to use library apps, audio books etc. Here are the facts:
-Dell Latitude D630 laptop
-Zorin 15.3 Lite. The only change I have made is replacing WiFi driver due to Broadcom 4311
-Laptop is on dock PR01X
-Using 15 pin VGA cable to connect dock to TV
-TV is 47” Vizio Full HD 1080P
The laptop recognizes the second display. I unchecked mirroring in the settings. I changed the resolution on second display to 1920x1080. I can move stuff over to the second display by clicking and dragging to the right. Expanding a window in the displays works as expected, filling the screen whether it’s on the laptop side or the TV side. Refresh rate defaults to 59.9 Hz and cannot be adjusted.
The problem is that the TV display image cycles vertically constantly, similar to old CRT sets would do sometimes. Any suggestions would be appreciated!
I saw where other monitor issues suggested starting with randr -q so I include that here as well:

Aside from Nvidia problems, the only thing i know of off the top of my head is to change the refresh rate or try re-installing the graphics drivers.
You have stated you cannot change the refresh rate in the GUI.
I wonder if forcing it with a terminal command may work...
In terminal, run
cvt 1920 1080 59
to calculate the refresh rate that you need.
You can then use the xrandr addmode command with what the CVT gives you. Just copy and paste in the contents aftermodeline.
For example, on mine, it would look like
I tried reinstalling first. The first command seemed to work but the second command returned the following:
sudo dpkg-reconfigure xserver-xorg
dpkg-query: package 'xserver-xorg' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: xserver-xorg is not installed
Seemed to work, doing the next one now:
