Monitor fails Handshake with Elgato 4k 60 capture

[Araujo]

I'll start this thread by answering the most common troubleshooting:

 

- Yes Cable work. Tested and replaced.

- Yes monitor works. Tested on different PC.

- Yes GPU works. Regular monitor works just fine. 

- Yes Drivers and system are updated.

 

 

Here is the issue.

 

My pc has a Elgato 4k60 PCI-E Capture card. 

That card's output goes to my Ugreen HDMI Switcher. 

That Switcher outputs to my main monitor.

 

My secondary Monitor is connected directly to the GPU.

I've been using this setup for 6 years with no issue. 

recently i wanted to upgrade my monitor, simply replacing it with a new one. 

 

It's the BENQ RL2755-B

My older monitor is the LG 24GN600-B

 

When i'm using the LG everything works perfect. When i unplug the LG and replace it with the BENQ i get a "No Signal Detected" message. The PC still operates with 2 screens, but i have no video on BENQ Monitor. 

The Monitor configs only allow me to select the Input ports and nothing else. When i plug the BENQ on my Laptop, video works flawless. 

 

Is there anything i can do to fix this issue?

I have to bump this. 

I kept at it, trying to understand what could be the issue, but so far no progress. This is a bizarre error for me so i have no idea how to resolve it and any support would be appreciated.

Giving this bump one more try as i have no solution forthis yet.
