HDMI switchbox? I don't know the technical reasons why pass through HDR doesn't work but it should be possible to just bypass it entirely I'd have thought.
You need a splitter to go down that road.
The problem is that the passthrough box is only HDMI 2.0. As I understand it, when a HDMI chain (eg. PS4 -> PSVR box -> amp -> TV in my case) boots up, the handshaking process negotiates an overall connection based on the weakest link in the chain. If that's the PSVR, the whole chain runs at HDMI 2.0. You need HDMI 2.1 for the expanded colourspaces that HDR needs. So, no HDR.
You can in theory do
Code:
/-> amp -> TV (for HDR flat games)
PS4 Pro -> splitter
\-> PSVR -> amp -> TV (for VR games)
But it's fiddly and expensive and chews up two amp inputs.
In other news my many year old Sony amp isn't HDMI 2.1 either. In fact it's only HDMI 1.4. Hurrah!
(Aside: this isn't entirely Sony's fault. The HDMI 2.1 spec was only finalised late last year, so it didn't exist when PSVR was released. But in general the specs process has been really bad around 4K and HDR, which is why there's a mess of different specs that are all incompatible with each other ie. HDR10 vs Dolby Vision. It's possible to buy a box that only outputs one and a TV that only supports the other and end up with no HDR. Like I said, it's a mess.)
