AiO will not detect my laptop screen via HDMI

[hale-pope]

Hello - I have a new all in one desktop. I want to use the monitor as an extenal screen for my laptop. I connect the hmdi lead from the laptop to the AiO hdmi input socket. The laptop 'sees' the external monitor (Fn and F5 tells me this) but the monitor will not detect the laptop. Is there a glaring reason for this? Thank you.

That's not how computers work. HDMI on computers is almost always OUTPUT, not input. If you state the exact model you have perhaps we can help.

Until then, it's user error and you're just doing something that's not possible.

Are you 100% sure that AIO has an actual HDMI IN?
What model is it?
What does the user manual say?

The AIO will not have an HDMI in, the port is to run multiple monitors off of the AiO

You are plugging a GPU into a GPU, not a GPU into a monitor.

The laptop doesn't see a monitor, the fn button just tells the Laptop how to treat a potential External display.

Hello. It is DEFINITELY an hdmi in port that i have and that I am using. It has the arrow pointing in as well, that differentiates it from the hdmi out that is right beside it. It is the Asus ET2321 and one of the prerequisites was to have an both an in and an out so that i can use the monitor as an external monitor for my laptop when i wanted too. I hope that helps. I know my laptop can work in this way as i do it a couple of days a week at work except that is vga only.

So what does the user manual say?

 

[hale-pope]

I have not looked at the user manual yet - i am just downloading it as it does not come with one, as seems to be is the way these days.

1. Does the book say anything about what button to press to enable that HDMI-In?
2. Does the laptop actually see the 'other monitor'?

Hi. Still wading through which manual to download. Not a 5 second job as there are 64 to choose from.

The laptop just says i can choose 'hdmi' when i press the correct keys on the laptop to view external screens when the hdmi lead is connected.

One other thing, when i plug in the hdmi lead a pop up box comes up on the AiO screen that says 'Asus input select - and then PC and HDMI so i guess one can choose and then has Menu:Exit. However, the pop is not responsive and the screen behind remains responsive, ie. the cursor actually goes behind the pop up/

I found the answer. Thank you to USAFret. 'Menu' is actually not on the touchscreen or keyboard - it is a tiny button on the underside of the monitor frame!

Not so much thanks Beegmouse and Basroil who just assumed I was an eejit and that computers don't work this way. They do when the are built to ... until they go wrong. It is not always user error.

A good community here though.

To be fair...HDMI-In is actually rare. The vast majority of systems, laptop, AIO, desktop, do NOT have that.

 

[hale-pope]

That is true. An equivalent HP would be nearly £1k .... but the speakers would be better! Crazy really.
