MacBook – Horizontal lines on screen and burned image rendering on macbook air 2015

That is a proprietary interface and there is not going to be a ready made solution to get it to adapt to being used as a stand alone screen separated from a Mac Book Pro.

Your best bet would be to sell the MacBook Pro as parts on eBay or something and just buy an external LCD or put the cash towards your next computer.

Its going to be an engineering effort as referenced in a similar question Can my Macbook Pro's display receive inputs from other sources?. Here is the answer provided by "Fake Name":

Yes, but it's not worth it.

You would have to take the laptop apart, design and engineer a custom converter to drive the LCD interface (internally, it's going to use LVDS to handle the interface between the laptop's motherboard and the screen), and power it somehow. It also would probably render the macbook from which you removed the screen unusable as a laptop.

It would take a few hundred hours of engineering time, and cost a lot in prototypes.

You are better off just buying a separate LCD.

The displays's physical connection is disconnecting and reconnecting causing the Mac to automatically detect settings from the display upon re-connecting, this seems to indicate a physical hardware issue.

Monitor Cable:

First make sure the cable is securely attached to the monitor too.

Failing that, I would try a different cable and see if the problem persists, there may be a short or continuity issue in the wires within the cabling.

Monitor:

Additionally try a different monitor and see if the problem persists, it is entirely possible that the Monitor's internal electronics may be failing.

The MacBook Pro:

If the problem persists after trying another cable or monitor it may be an issue with the DVI port or even the connection of the DVI port to the motherboard on the MacBook Pro.

If you try gently applying very slight force to the cable end near the MacBook Pro while the monitor is connected in directions such as: up, down, left, right, etc and that causes a change in what your observing, the DVI port may be failing.
