Connecting my skybox to my projector

[sarahmcgregor]

I have just bought a new  projector and sound system I'm trying to connect the sky Q box to gaimoo gm200. I purchased a 4K high definition HDMI wire and the sound is coming through, but not the picture. How do I sort this

How long is the lead?

It seems the projector doesn't support HDCP?  If this is the case then it will simply not work.

It must support HDCP surely?

@Chodley It says it does online but no idea how to solve @sarahmcgregor's issue.

First thing I would try is 1080p output instead of 4k

@sarahmcgregor 

To be able to receive UHD from a main Sky Q box an output device must support 4K at 60Hz and HDCP 2.2

The manufacturers of extremely budget projectors tend to cut corners: it's unfortunately quite legal to advertise '4K' without meeting either of these specifications (i.e. 4K at 30Hz without HDCP)

Also if the Q output is running through an audio device to reach the projector, that device needs to support 4K at 60Hz and either HDCP 2.2 or HDCP passthrough too.

[Chodley]

The Q box outputs 50Hz unless you use an app though at which point it might use 60 if you've turned that option on.

I would lay money it supports hdcp. I don't think that's the issue but probably the projector only supports 4k@30 as you suggested.

You'd think but none of the specs I could find mention it...

Definitely worth trying some different resolutions.

@Chodley 

I tend to advise looking for 4K at 60Hz because that's how reputable manufacturers label hardware (the alternative being 4K at 30Hz or no mention at all ; )

Yeah good point, if they can do 50 they can almost certainly (and more likely to label the fact) do 60.

@Chodley 

I suspect it's a chipset thing, with the relevant wholesale silicon components specified for either 30Hz or 60Hz (and now 120Hz) and priced accordingly on the global market.

[sarahmcgregor]

I've tried that. It's not working

[TimmyBGood]

@sarahmcgregor 

You've acquired an extremely budget device from a manufacturer which appears to have no internet presence of its own at all: that's probably not ideal.

Tried what? Changing the output to 1080p?
