Note: HDMI 1.4 Output Resolution

The latest specifications allow HDMI devices to support 4k*2k resolution, supported display modes including: 3840*2160@24hz/25hz/30hz and 4096*2160@24hz.

When the 1.4 standard is higher than the 1920*1080 resolution, only two resolution 3840*2160 and 4096*2160 are supported, but 2560* is not supported 1440 resolution. And to achieve these two resolutions also need to meet the requirements of the refresh rate. The normal LCD refresh rate is fixed to 60HZ, so the output of these two resolutions cannot be reached. Higher resolution also requires high speed HDMI cable connections and hdmi-in input to support HDMI 1.4 standards. So the average HDMI 1.4 notebook external LCD monitor can only choose to 1920*1080 resolution.
