What It Actually Takes to Run 4K at 240Hz

Two billion pixels a second is the real number behind this specification: 3840 by 2160, redrawn 240 times. That is more data than an HDMI 2.1 link was built to carry, so every screen at this tier either compresses the signal on the way across or uses a newer connection that sends it whole.

Which route your setup takes is decided by the graphics card, not the panel. Read the DisplayPort version printed on the exact card you own, then look at the panel technology, then ask whether your games will produce frames anywhere near that ceiling.
