7680x4320 resolution

8K UHD · 16:9 · 33,177,600 pixels · 33.18 megapixels · Broadcast and TV
What 7680x4320 is
Sixteen 1080p frames, four 4K frames. At normal viewing distances the resolution exceeds what the eye resolves on any television that fits in a house, which is why the format has stalled at the display end and never arrived at the content end.
The numbers
| Width | 7,680 px |
| Height | 4,320 px |
| Aspect ratio | 16:9 |
| Total pixels | 33,177,600 |
| Megapixels | 33.18 MP |
| Compared with 1080p | 16.00× the pixels |
| Compared with 4K UHD | 4.00× the pixels |
What 7680x4320 costs to move and to store
A frame is width × height × three bytes of colour, before any compression touches it. At 7680 × 4320 that is 99.53 MB per frame, and video is frames per second:
| Frame rate | Uncompressed | An hour of it |
|---|---|---|
| 24 fps | 2.39 GB/s | 8.6 TB |
| 30 fps | 2.99 GB/s | 10.75 TB |
| 60 fps | 5.97 GB/s | 21.5 TB |
| 120 fps | 11.94 GB/s | 43 TB |
Nobody ships that. It is the number codecs exist to get away from — a streamed 7680x4320 feed runs at a few tens of megabits, which is a compression ratio of several hundred to one, and it is why a still frame from a stream looks worse than a photograph of the same scene.
How close you have to sit for 7680x4320 to be worth it
The eye resolves about one arcminute of detail. Past a certain distance the pixels merge whatever the panel does, and a higher resolution stops being visible rather than stopping being better. That distance is the pixel pitch divided by the tangent of one arcminute:
| Screen | Pixels merge beyond |
|---|---|
| 13.3 in monitor or laptop | 0.13 m (0.4 ft) |
| 15.6 in monitor or laptop | 0.15 m (0.5 ft) |
| 24 in monitor or laptop | 0.24 m (0.8 ft) |
| 27 in monitor or laptop | 0.27 m (0.9 ft) |
| 32 in monitor or laptop | 0.32 m (1 ft) |
| 43 in television | 0.43 m (1.4 ft) |
| 55 in television | 0.55 m (1.8 ft) |
| 65 in television | 0.64 m (2.1 ft) |
| 75 in television | 0.74 m (2.4 ft) |
Sitting further back than the figure for your screen, 7680x4320 and the next resolution down look the same. That is the whole argument about 4K televisions in ordinary living rooms: the resolution is real and the seating position usually is not close enough to show it.
Pixel density at common screen sizes
A resolution on its own says nothing about sharpness — the same 7680x4320 panel is dense on a laptop and coarse on a television. Density is the diagonal in pixels divided by the diagonal in inches.
| Diagonal | Pixel density | |
|---|---|---|
| 13.3 in | 663 PPI | High density — the OS will scale the interface |
| 15.6 in | 565 PPI | High density — the OS will scale the interface |
| 24 in | 367 PPI | High density — the OS will scale the interface |
| 27 in | 326 PPI | High density — the OS will scale the interface |
| 32 in | 275 PPI | High density — the OS will scale the interface |

Frequently asked questions
What is the aspect ratio of 7680x4320?
16:9.
How many pixels is 7680x4320?
33,177,600 pixels, or 33.18 megapixels.
Is 7680x4320 higher resolution than 1080p?
7680x4320 has 16.00× as many pixels as a 1920×1080 frame.
What size screen suits 7680x4320?
Pixel density is what decides that. 663 PPI at 13.3 in, 565 PPI at 15.6 in, 367 PPI at 24 in, 326 PPI at 27 in, 275 PPI at 32 in. Below roughly 110 PPI text starts to look coarse; above about 200 the operating system will usually scale the interface rather than render it at native size.
