Running Multiple Screens

[nikaiyo2]

Bit of a random one here, I have a bit of machinery that has a “PC box” and screen. I would like to run another display, showing exactly what is on the main screen. The software is completely locked down, so we can’t access any setup/ user controls for the computer.

Can I just get a Y shaped/ splitter VGA and stick another monitor on it assuming similar size etc. It does not need to show detailed pictures or anything like that, just some very basic text & graphics.

Is there a limit on the length of a VGA cable? I think I will need about 10 or 15m!

Yep, just buy one of these if it’s a standard analogue VGA connection

Euronetwork VGA splitter: 1x HD15 M to 2x HD15 F, 0.2m https://www.amazon.co.uk/dp/B000BB0C9C/ref=cm_sw_r...

Limit length on vga is around 50m and even then, that's pushing it.

In a venue I used to have, we had to have a 50m cable to reach from the computer to the projector. The image would be ghosting and not clear.
Changed to a system of a vga to cat5 converters that could have sent a clear image up to 150m

10 to 15m won't be a problem with decent cables.
