Maybe it's me - blu ray players and 4k tv

[CapitalOne]

Hi all

I'm scratching my head, trying not to just buy a new HD Blu Ray player...

I have a Samsung 6 series 4k TV which works great, and my Roku, HTPC and Fire Box all work fine. However when I try my two admittedly old blu ray players the 1920x1080 signal is detected but the screen is blank. I understand this might be something to do with HDMI handshaking....so.....

I've updated to latest firmware on both players on a 1080 tv which works fine
I've tried every combo of cable and input on the tv

Anything else left to try?

Players are Phillips BDP5000 (ancient) and Samsung BD-F5500

Many thanks

I've used all 3 cables I use on that TV, including one I use for the HTPC which plays 4K video and desktop

eta - the bluray players output 1080p which is at least detected - the label that pops up when you select the relevent HDMI source says 1080p

Yes, they work fine on a 1080p plasma - I used it to upgrade the firmware on both just today
