AN515-45-R52B. Cannot connect two monitors at once.

Theforbbbidd · October 17

Hi.

I own Acer Nitro 5 AN515-45-R52B.

I have 2 monitors i'm trying to connect. One via HDMI port, another using USB 3.0 to single HDMI adapter.

Both of these work seperately, however they don't work at the same time allowing me to use 3 screens at once. Simply put, I can only connect another monitor if I unplug the first one.

The adapter i'm using is cheaper Chinese production for 20$ but it does work if I'm not using core HDMI port.

I'm looking into alternative solutions such as purchasing a more expensive USB to double HDMI adapter but i'm trying to get to the bottom of this problem fearing running into the same issue even with more expensive hardware.

[Edited the thread to add model name to the title]

This has been answered in your previous post with the same topic 😑

@Puraw I'm sorry if I misunderstood something but this part felt unanswered.

Lack of USB-C port display capabilities were explained to me. And alternative products that might work.

But there was no answer regarding why USB 3.0 port with adapter and core HDMI port might not work at the same time.(Whilst working seperately).

Thanks for your help.

That is because I did not comment on that part of your question, because it should work: In Windows right-click on your desktop and select Display settings. You will see both monitors listed. If not, click on Detect. Select Extend these displays from the Multiple displays dropdown menu. Arrange the displays by dragging and dropping them to match their physical layout.
Check GPU Assignments:
Ensure that the integrated GPU is handling the USB 3.0 to HDMI adapter and the dedicated GPU is handling the HDMI port (default). This can sometimes be configured in the NVidia graphics control panel.

Why you don't just get the USB3.0 adapter I recommended with two HDMI ports like many do is not clear.

Hope this helps 😉

I will get the adapter you recommended if I can't get my current setup to work, which in your own words SHOULD work in theory. This post was intended to try and troubleshoot that.

Thanks for your assistance!

To expand a little bit, there should be 3 screens total in display settings including the laptop screen.

The issue that there's only ever 2 screens at the same time working, connecting 3rd screen, disconnects the 2nd one and its not possible to detect it using 'Detect other display'.

I'm wary of spending 100$ on double HDMI adapter and running into the same problem because for some reason it's not possible to have 3 screens on at the same time.

If you have any ideas i'd appreciate your input!

Yes, the Acer Nitro 5 AN515-45-R52B can support three screens: the laptop screen and two external monitors. Here’s how you can set it up:

HDMI Port: Use the HDMI port to connect one external monitor.
USB3.0 with an active graphics adapter and HDMI out port

And the best way with the USB3.0 adapter I recommended with 2 HDMI out ports.
