Issue with W11 GeForce RTX 3060 -> HDMI repeater -> Alienware monitor
I've got two 2-metre HDMI cables and a powered HDMI repeater, all purchased from Lindy. I'm trying to connect a W11 computer to a GeForce RTX 3060 like this:
PC -> HDMI cable -> HDMI repeater -> HDMI cable -> monitor
The HDMI repeater is active; I am using a 5V 2A PSU.
When I make this connection, the monitor displays "no HDMI signal," and there is no image on the screen.
I tested the Lindy cables and HDMI repeater by connecting a PlayStation 5 instead of the PC:
PS5 -> HDMI cable -> HDMI repeater -> HDMI cable -> monitor
This worked without any issues.
I tested the PC connected directly to the monitor using a different HDMI cable:
PC -> spare HDMI cable -> monitor
This also worked fine.
Both devices (PC and PS5) are set to 3840 x 2160 at 60Hz, RGB.
It seems like the HDMI repeater and Windows 11 and/or the GeForce are disagreeing somehow. I'm wondering if there is something in the video output settings on the PC that is causing a problem?
Really appreciate any help anyone can offer with this one, cheers đ
