PC to Monitor via HDMI Switch, No Signal.

[dead2k1]

I recently bought an HDMI switch hoping to run a bluray player and my PC into the same monitor in my bedroom. After installing it (a belkin Pro 1000 2 input), the monitor gave me a HDMI: check signal cable message so I assumed the switch was faulty and replaced it with a J-Tech Digital HDMI Switch 3x1, and have found the same problem occurs.

Directly plugging the PC (GTX670WF) into the monitor is fine, but adding a switch gives me this 'signal cable' error.

Any idea what might be causing it? my theory (which is rather unlikely) is my cables aren't carrying the signal strong enough. I have 3ft from the PC to the switch, and 3ft from the switch to the monitor. (all cables tested and working).

I looked up the switch. It gives the option of selecting between two HDMI 2.0 sources. I would guess that since you replaced the switch that the problem is in the HDMI cable after the switch. The switch also has to be set to an active HDMI 2.0 signal.

I get a similar error (on my HDMI connected HDTV) every time my system goes into sleep mode. So the monitor may not be detecting an active HDMI source.
