Hello,
I have a computer power supply, and the 12v runs a current of 16Amps. would this be suitable for a screen that requires 2.5 amps?

Yes it will.
Any load will only draw as much current as it requires .....
HOWEVER if there is a problem and you accidently short out something allowing massive currents to flow, then a low current supply is less likely to destroy thing (tracks, components)
The safest method is to add a 2.5A fuse in series with the supply feeding your screen. (It may already have one fitted externally or internally)
That way you have plenty of power, but it will be protected.
Before you connect this, you may wish to have it checked.

It's a simple matter of sticking a load on and measuring the ac componet across the 12v (usually with an oscilloscope).
