Did it show this more or less instantly or after say 4+ seconds?

Not instantly, shows about 4 to 5 seconds after the "Connecting to" message.

That almost certainly means the firewall on the primary is blocking port 30568 or the primary has an ARM processor or very old AMD/Intel 64 bit processor.

Oh no, so the cause is the firewall port blocked, as I wasn't able to send audio to my primary because of the port blocked (message saying that the port 30567 is blocked).

And it's not possible for me to create an allow rule, as my primary is my work computer and firewall settings are all GPO based.

Is there any chance to change the incoming port to the secondary (my personal laptop, so I can open the port from there) to circumvent this?

Anyway, thanks for the help!

I installed Multiplicity on my desktop computer and set a Primary, also tried to use Seamless Display with my secondary and I'm getting the same error.

I already disabled Firewall on both computers and still got the same issue (4-5 seconds in Connecting to screen and have the Connection failed due to an unknown protocol error).

So, maybe is not related to the firewall port.
Also, my primary computer (desktop) has a Ryzen 5 computer, and my secondary (Laptop) has a 12 gen Intel processor.

Both with Windows 11, fresh new installation.

I have the same issue. I added an rule on my firewall (ESET), but still get the error.

Can you try switch your primary as your secondary and vice versa and test if works?

Yesterday I tried and works, so I'm not sure if it's a firewall issue.

With the BETA 2 there's an error code 3 on my case.

Hi,

Has this issue with Seamless Display been resolved. I'm deciding whether I should buy it or not and the only feature I'm interested in is this one. All other features work fine.

In my case, the primary computer is a Dell XPS laptop with Windows 11 and the secondary computer is an old Dell Inspiron 3277 AIO, with Windows 10 Home (recently cleaned up). I'd love to use it as an additional monitor. 

Please let me know. Thanks.

Hi,

I have "version 4 Pro Trial" that I downloaded 2 days ago. I can't download any other version because it does not show up on my account (like the purchased products). 

Thanks.

If you on trial, you can not get the Beta release.
