Answer: Resolution of Blu-ray Disc

Generally speaking, there are only two types of resolution for a commercial Blu-ray disc: 1080P (19201080 pixels) and 4K UHD (38402160 pixels).

But what are 720P Blu-ray and 2K Blu-ray?

720P Blu-ray usually means video resolution, but not Blu-ray disc resolution. Some people will rip 1080P Blu-ray to digital video as 720P (1280*720 pixels), then the converted video can be called 720P Blu-ray. As for 2K Blu-ray, it is the same as 1080P Blu-ray in the field of home video, but "2K Blu-ray" may not be an accurate description.

After knowing the above information, let's focus on 1080P Blu-ray and 4K UHD Blu-ray. That's the only two types of Blu-ray disc resolution.
