In the process of setting up some informational displays at work using some old PC's to driver standard 23" TFT's. It is not an ideal situation but its cheap and thats what we need whilst we test it.

I have a single PC outputting to 2 displays using an unamplified splitter and going over approximately 25m of good VGA cable (custom installed by our sparkies).

The problem is that both screens are showing considerable ghosting and a pink tint. We have tested with a shorter length of cable and it is less noticeable but is still there.

Is there anything we can do to improve things? Looking at buying a boosted splitter but not sure if it will work and its more money I need to spend.

Some websites have mentioned ferrite rings and the sparkies are looking to get some for the cables but could be a few days.

Any help or ideas welcome.

Thanks
 
The fact is a long run of analogue vga is going to cause issues. Do you not have an old PC that you can put on the network and have it next to the monitors to drive them? if its just for info display you could use a defunct pentium4 or something...
 
Considered that but seems an expensive route. Quoted £90 per pair of baluns.

Have told the sparkies to sort it out. Seems they cut the cable and rejoined with a block rather than cut a big enough hole to run it intact...

Wont sign off the invoice until its right.
