Playstation 4 on a Thunderbolt display? Is there any way at all that I could connect a Playstation 4 to a Thunderbolt display?
No. You can't connect a Thunderbolt display to it. No adapter has ever been created to connect Thunderbolt devices to USB 3 (what the PS4 has). The performance would be horrendous and not usable even if one was ever made.
