HDMI 2.0 vs. 1.4: What has been improved?

When HDMI 2.0 was announced in 2013, many people weren’t sure if it could work with their TVs. However, this new HDMI version is friendly and can work with all cables designed for the 1.4 version. Here is a summary of how the two differ:

What is hdmi2?

The 2.0 version is more about maximum bandwidth but not resolution. While HDMI 1.4 systems transfer data at up to 10.2 Gb/s, the 2.0 systems can do it at up to 18 Gb/s.

4K Video At 50p and 60p

HDMI 1.4’s bandwidth can deliver 4K video at 24 frames per second. On its part, HDMI 2.0 can do the same without compromise at about 60 and 50 frame rates per second. This enhanced speed and video resolutions are ideal for gaming.

Enough bandwidth for 10-Bit And 12-Bit Color At 4K

Due to its extra bandwidth, HDMI 2.0 can transport 4K video at 12-bit and 10-bit color depths. However, HDMI 1.4 could only do it at 8-bit color depth. Hence, HDMI 2.0 guarantees you high-definition images and video resolutions.

Dual Video Streams to The Same Screen

When it comes to HDMI 2.0, bandwidth is everything. With 18Gb/s, this cable can deliver two different video streams to your screen. In other words, the maximum bandwidth allows a comfortable pipe to transport two high bi-rate streams. However, such a dual stream isn’t possible with HDMI 1.4.

The HDMI 2.0 supports dual streaming to your screen.
