We have a Gigablue UED 4K box with OpenVix, coupled with a Sony STR-DN1080 amp and a Samsung QE43Q60 4K TV.
The amp offers the facility of upsampling 1080p content to 4K. On the Gigablue/OpenVix I've set the Menu > Setup > Settings > Audio & Video > video output to 1080 @ 50hz. Sadly though I get no apparent "4K" as far as the TV is concerned, which shows the input resolution as 1920x1080. I've tried rebooting the box, amp & tv without success.
On closer inspection the help docs for the Sony amp state: "The upscaling function works only when video signals are received via the HDMI IN jacks. HDMI input signal must be 1080p/24 Hz 2D signal". Would I be right in thinking that as there only seem to be options for 1080p 50/60hz on the Gigablue/Openvix mean I won't be able to get the amp to upsample 1080 to 4K - as the amp is expecting 1080/24Hz ?
Thanks
