I’ve been asked to install a new monitor in an EMS (Ambulance) station. The monitor is by the garage doors, and needs to mirror another monitor connected to a computer on the other side of the garage. This is a volunteer EMS group, so the budget is limited. I’d rather not buy a new graphics card, but it’s not out of the question.
We’ve measured the cable run at roughly 55ft (17m).
The monitor we need to mirror is connected by DVI.
There’s a second monitor also connected via VGA.
The computer has no third monitor port; it has just 1 VGA port and 1 DVI-D port. It’s a cheapish old Dell. The sole use for the computer is showing currently active calls, and the people who’ve paged in to take them.
What’s the best solution to setup display mirroring on the new monitor? No kb/mouse is required at that distance. This is view only. To be clear, the monitor is already mounted. Just need to know the best way to get the signal to it, given the constraints I have.
I’ve taken a look at kits: I can get either DVI or VGA splitters, and 20M cables for both.
Are these options decent, or would I need a powered splitter? Bear in mind, that’s $10 vs $150 it seems.
Which is preferable over longer lengths? VGA or DVI?
