HDMI Switcher

[Brynsta]

So I have too many HDMI connections for my TV (5 HDMI connections and only 4 ports) so I purchased a HDMI switcher for my SkyQ box and my Firestick, but the Sky box flashes on the display then off. It's a powered switcher by UGreen 4K 120hz HDR one, any reasons why it isn't working?

Hi @Brynsta   Perhaps it is not HDCP compliant. What is the exact model of the switch?

[Brynsta]

It is a UGreen 3 in 1 HMDI Switch. https://uk.ugreen.com/products/ugreen-4k-120hz-hdmi-2-1-switch-3-in-1-out?currency=GBP&variant=46598... That's the link, checked the booklet and says it is HDMI compliant and also suggest that a problem could be the device I'm using isn't HDCP compliant, which the sky q box is

Hi @Brynsta   It looks like it should work, what happens if the Sky Q box is the only input. Note HDCP compliant means your TV, not the Sky Q box which requires the switch to be HDCP compliant. Not the other way round.

I tried that, works for a slightly longer spell, maybe 5 seconds, the. The screen went grey and then black, then the no signal input again. TV is an LG G4 so shouldn't have any issues with HDCP

How long are the cables?

[Brynsta]

Standard sky one from the box to the switcher, same again from the switcher to the TV, even tried swapping the switcher to the TV one to a brand new UGreen 0.5 hdmi cable, same result

Well, in theory, it should work.

A long shot could be the switcher is 'faulty'.

I would note that the specs do not list the 50Hz used by the Sky box.  But I suspect this is red herring as signals are just passed through - I doubt there's any 'processing' done.

That's what I'm wondering, I will try and get a new one from them and see if that fixes it. Hoping it will, not sure what to do otherwise!

Is it externally powered? We've seen issues before with switches relying on the Sky Q box's HDMI port for power.

Specs say it's powered and needs 1A.

[Brynsta]

Yup, plugged into a wall USB plug
