Monitor commands are used with packet sniffing programs like Wireshark

You will plug your computer to the output port

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

I tried to reproduce what you have and got the same thing.

My guess at this point is the IOS version. I'll dig a little deeper. Meanwhile, check this link here

SUMMARY STEPS
1.    enable  
2.    monitor capture capture-name access-list access-list-name  
3.    monitor capture capture-name limit duration seconds  
4.    monitor capture capture-name interface interface-name both
5.    monitor capture capture-name buffer circular size bytes
6.    monitor capture capture-name start
7.   monitor capture capture-name export file-location/file-name
8.   monitor capture capture-name stop  
9.    end

I initially thought the configuration was on an ASA
The wireshark reference applies to low end devices that don't support Embedded Packet Capture.

The capture needs to be created first and based on the command syntax, "1" is supposed to be the capture name. In the IOS version used, name is not an option after "monitor capture...". The only available options are buffer and point.
