Using a dead laptop as a second monitor

Okay so I wanna turn my old dead laptop into a second monitor for my current PC, I know this may sound absurd but I also don't wanna use a controller as I can't find anyone where I live or idk where to look actually.
The laptop has something fried inside, I'm not sure what but I don't even get the BIOS splash screen (And frankly it's not worth the hassle trying to fix it) but the screen was a great 17" panel. I have access to basic tools and I could manage with some soldering. If you guys have any ideas please hit me up, thanks! :)

tl;dr wanna use my laptop's monitor without using a controller

A lot of laptops use embedded displayport and rarely hdmi so if you could somehow convert those to regular connectors its possible.

I can only bump and wish you luck.

Please dont bump. Only comment with constructive posts. Thank You. I knwo your intentions were in the correct direction

Basically what you need to do is... Convert the eDP (Embedded display port) to Display Port or Mini DP (You can probably find adapters around or make one yourself if you know the pin outs)... After which you can then proceed to buying a DisPort to HDMI port adapter if your videocard does not have a display port (Most Modern AMD cards do).

I do not know what the eDP pinouts are but here are the pinouts for display port. Match these up with what you find on your laptop manufacturers adapters.
Multimeters are handy. Use the correct AWG wire. You need to be as precise as an engineer as possible to prevent damage both to the laptop display and your video card.

To find your laptop pinouts you will still need more than a multi meter.. you will need to get a hold of your laptops adapter schematics... GOOD LUCK but if you do.. repost and show us.. We might be able to help haha..

I wish you the best of luck friend

What laptop are we talking about here?

It uses a certain (proprietary?) connector, not HDMI and it doesn't look like DP, though I could be wrong

An old HP DV7 NR-1135 (or something similar)

My GPU certainly has DP, it's not the best but it's a 7850 OC version so it's capable.
I certainly lack experience in these connectors so I probably wont be able to do what you've said, I could give it a shot though, the laptop is fried and is as good as a paper weight right now.

Damage to my video card? Well crap.
I might give it a shot anyway, thanks a lot man!

Read the rules.

If you have posted a thread with your question and if no one answers it within the suitable time frame, either wait or bump once in a while. Do not start making duplicated threads. These will be deleted.

There's really not any problem with bumping unless it's stupidly excessive - it's better than getting no answer or this guy making another thread.
