Thanks.

How much more use can I expect out of this?

I only need like 200 hrs over three months.


Depends. It's like a car windshield. One good bounce and the crack spreads. With LCDs, you may sever an internal trace that will take out a significant portion of the image. If you can use it as is, try not to disturb it.

Alternatively, you can pick up a cheap monitor from a tag/yard sale or thrift shop and connect it to the laptop.
