Reason 1: Your device is not advanced enough to play HD video
Firstly, you need to verify whether your device is advanced enough or not to meet the minimum requirements to play HD video.
Minimum requirements to play 1080p HD videos on PC
1.Processor: 2.4Ghz (dual core) or 3.5Ghz (single Core) processor.
2. Graphics: Nvidia/ATi having bare minimum 256MB Video RAM and core clock 600Mhz.
Requirements to play 4K 2160P UHD videos on PC/Mac
1.Integrated Graphics solutions that support 4K external displays (8GB RAM recommended with integrated graphics solutions);
2.Discrete Graphics cards that support 4K external displays;

So if your PC/Mac doesn’t meet the requirement, you will be not able to play this 1080p or 4K video. To solve the problem, you should upgrade your computer configurations to support to play 1080p/4k videos. But this way is too expensive that not everyone can afford it. So the cost-effective way is to convert 1080P HD/4K UHD video to lower video resolution with a video converter.
Reason 2: The HD video format is not supported by your media player.
Many multimedia players now can play 1080p, like iMac Retina 5k, it can even play 4k video. In this case, why can’t they still play 720p/1080p/4K?
