external gpu for laptop question

[CATSLUVER420]

So I found out that you can actually have an external gpu for a laptop. you probably cant unplug the gpu of laptop, but on most laptops you can remove the wireless card and then use a mPcie to pcie adaptor, where you can plug in a gpu that you power with a psu from a desktop pc, but you probably have to use a normal monitor.

If I do this, how will my laptop know, which gpu he should be using?

I'm not sure how the screen of the laptop will get the display signal, but in theory this would work. The BOIS of the laptop would also have support the graphics card. This could be useful if you want to have a GPU for computer or something, but I don't know about for driving the internal display.

i know that u cant use the internal display, but can I set a gpu priority somehow, so the desktop gpu will do the work, cuz sometimes the laptop will still use the normal mGpu and just say that there is another one connected

Well if you have a AMD or NVIDIA card in a laptop you can remove it.

i dont want to do that, i just want to add a desktop gpu, and make the pc boot with it as long as it is connected

Ive seen a couple of guides online, it can be done quite easily however there are a number of problems. firstly you must make sure that your CPU does not bottleneck the GPU. Next a problem will be dust collection on the GPU. Also if the GPU needs extra power you will have to buy a PSU. the only way around the dust collection is to build and enclosure for your components.

 

Heres a pretty good guide that i found http://www.techradar.com/news/computing-components/graphics-cards/how-to-make-an-external-laptop-graphics-adaptor-915616

 

i dont recommend this i would say it might be better to build a pc?

i wanna game on it. I actually just want tp know more about it. my cpu is no bottleneck (Intel core i7 4702MQ)
