If the Amp does not support 4k, why not connect the PC to a HDMI switch so you can choose between the TV or Monitor, sound will have to run separate to the AMP either standard phono connectors or digital (coax or optical). The other gadgets like Sky dont support 4k anyway (well, your bluray player may) so they can connect to the Amp as usual but only output 1080.
Q though...would you see the benefits of 4K in a game on the TV at the distance you view it from? On the Monitor yes but the distance to the sofa, wouldnt a downsampled 4k image or even 1080 be enough?
