Let's start with the result:
Picture 1: Setup
Picture 2: The hole for the 2 hdmi cable
Picture 3: GPU-Z
Picture 4: 3dmark benching, comparing original screen and external screen.
My setup list:
Acer Nitro 5 (AN515)
dGPU: GTX 1050
eGPU: second-hand RX 5500 XT (Driver: adrenalin 2020.2.2)
I bought this laptop because it was on sale and pretty cheap. But when I start on some games I realized it was a mistake.
GTX 1050 can only run ACOdyssey and ACOrigin with low quality and 30fps. Division 2: low quality 60fps. AOE2DE: medium quality 60fps.
Last week a saw others selling EXP GDC 9.0b(M.2 M key) by second-hand price, and that was the start of this project.
1. Insert M.2 converter to my laptop M.2 slot (AN515 has two M.2 slot and one 2.5 inch SSD slot)
2. Connect all cables to the EXP GDC as official guide (Caution: the two hdmi cable cannot be mistaken with each other. You wound see your GPU fan does not function if you set up in wrong order)
3. Boot laptop
4. Disable GTX 1050 in device manager
6. Reboot laptop
7. Manually sets each game running by egpu.
(Last step: make a hole for the cable with a saw, and locked the laptop shell back.)
I've never thought it wound be that easy, because there is only one case of Acer laptop with M.2 M key in the BUILDS.
However it just succeed! Not too difficult!
Now ACOdyssey can run 60+ fps on middle quality; 45+ fps on high quality.
There are 3 problems remained:
1. If I shut down after testing the bus interface in GPU-Z, it wound show blue screen or stuck at the moment.
2. Longer time of booting and shutting down. Sometimes shows blue screen when shutting down, but it will shut down itself just later.
3. Dell DA-2 220W is quite noisy.
I made a metal case for my egpu ~~ cheers !! (PSU: FLEX ATX 350W 80+GOLD)
Did you have to tinker with the BIOS or something similar? I'm trying a similar setup with a 2019 Acer (Aspire, not Nitro), but I want to prepare myself in case I need to apply a custom BIOS or something like that.
How's your setup working now?
As I said, I've never thought it wound be that easy~
All I have done were just making sure hardware at proper position, installing adrenalin, and disabling NVIDIA GPU.
No further need for a custom BIOS in my case.
It works well in all games like my desktop.(No any major problem of compatibility detected now.)
I discarded the Dell DA-2 220W, and use a Flex ATX power instead.
And I'm designing a box for more portability.
I'll be waiting for your good news~
Thanks for your answer. I should be testing everything in the upcoming week(s). I'll be sure to keep you updated!
I bought a Dell DA, but if I intend to change it in the future, I'll take a look at the Flex ATX you mentioned.
