# DisplayPort 1.4 size

**DisplayPort 1.4: 32.4 Gbit/s — 4K at 120 Hz with compression**

The common standard on desktop graphics cards. It reaches 4K at 120 Hz using Display Stream Compression, which is visually lossless in normal use. DisplayPort supports daisy-chaining monitors and adaptive sync natively, which HDMI historically did not, and it is generally the better choice for a computer where HDMI is the better choice for a television.
