Network VGA Extender RGB issue

[techguy1991]

Hi all,

 

Due to building design we plan to use a VGA Cat5/6 extender to allow teachers to have a second monitor to their desk.

 

To give you an idea of the layout its a relatively new school, our science classrooms have a teacher desk which is an island, the only way for teachers to have a monitor on their desk is to either have wires across the desk (which is a no go from the start) or use the infrastructure of the network cat6. Each island has a network port and so does the interactive board / PC. our network runs to a hub room on the same floor.

 

To test the deployment we purchased a portta vga extender https://www.port-ta.com/extender/vga-extender/porttar-vga-utp-extender-with-audio.html

 

At first all seemed well, however I and the teacher have noticed an issue with the colour sync with the monitor that uses the extender, Blue seems to be more shifted to the right then other colours which causes a slight blur, which with long use can cause the teacher to have a headache.

 

any suggestions with what I can do to realign the colours? Does anyone else use an extender and have seen this issue before?

 

I have tried to adjust the res, and the gain & flex

 

Cheer all.
