Many clients asked what the HDMI v1.3 v1.4 or v2.0 version compatible device means? Which one is better for my TV?
Actually the HDMI standard is a serious specification for Video/Audio. For generic users it is too complex, but if you know few specifications then you can purchase a correct device.
In here we just focus on video (resolution and refresh rate) only.
1. HDMI 1.3 Video support up to 1080P (1920 × 1080 at 120 Hz or 2560 × 1440 at 60 Hz)
2. HDMI 1.4 Video support up to 4Kx2K@30HZ （4096×2160 at 24 Hz, 3840×2160 (Ultra HD) at 24 Hz/25 Hz/30 Hz, and support for 1080p at 120 Hz）
3. HDMI 2.0 Video support up to 4Kx2K@60Hz (3840 × 2160 (Ultra HD)) at 60Hz
For the refresh rate, generally 30Hz is perfect for watching films, but gaming and some video streaming could make great use of 60Hz.
Note: "Ultra High Definition" is actually a derivation of the 4K digital cinema standard. However some devices can not show images in native 4096 x 2160 4K resolution,instead of a slightly lower resolution of 3840 X 2160, it is called Ultra HD (UHD) consumer format also.
This is one reason why some brands prefer not to use the 4K label at all, sticking with Ultra HD or UHD instead.
