@zeondx Unfortunately, probably yes. As far as I understand it this is what we need for 4k on pc's:
- Motherboard with HDMI 2.0a (which even the newest graphics cards don't have I think), and support for HDCP 2.2
- Intel processor with 630 Graphics (so at least an i5 CPU)
- And of course a display with HDMI 2.0a
So unless you have a motherboard that already has 2.0a you definitely need a new one. It would be so much easier and cheaper if the graphics cards from AMD/NVidia support this. Than you just have to buy a new graphics card. Now you have to buy an entire new computer basically.
