    Question 4k hdr data rate math doesn't add up

    Glenwing, I have found this file very helpful. What about 1440p monitors? Is there a file which lists its blanking intervals? I came across this monitor. I was wondering if it can do hdr with hdmi 1.4 or is it just simulating it. Based on 1080p and 2160p, it seems that the data rate at 4:4:4...

    Question 4k hdr data rate math doesn't add up

    How does compression work for live-streaming? Here are some Netflix calculations: Resolution FPS Chroma HDR/SDR Data Rate 4K 24hz 4:2:0 10 bit 4.46 Gb/s 1080p 8 bit 0.89 Gb/s Netflix requires 25 Mbps and 5 Mbps respectively. So, each uses 178.2x compression. The numbers for Google...

    Question 4k hdr data rate math doesn't add up

    So, according to this, to calculate the data rate for 4k 10 bit , you would have to do 4400 px × 2250 px × 60 Hz × 10 × (1 + 2 × c) where c = 1 for 4:4:4, c = 0.5 for 4:2:2, c = 0.25 for 4:2:0 In your way of calculating for 4:2:2, But I found that 4:2:2 calculations only match with the...

    Question 4k hdr data rate math doesn't add up

    I miss-copied it from the link, it should be 22.28 Gbit/s. And your answer also matches 17.82 × 1.25 = 22.28. To confirm, regardless of whether the color depth is 8 bit, 10 bit, or 12 bit, HDMI before 2.1 would break it into 8 bit blocks and transform them into 10-bit sequences. So, we always...

    Question 4k hdr data rate math doesn't add up

    3840 x 2160 x 60 x 10 x (1+ 2xc ) = 14.93 Gbps where c=1 for 4:4:4 (it would be .5 for 422 and .25 for 420) Also using 60 hz and 10 bit hdr. It should be 22.98 Gbps. Where am I wrong? Edit: 22.28 http://community.cedia.net/blogs/david-meyer/2017/06/22/4k-60-444-hdr
