Dolby's official setup guides list every speaker role in each configuration. Count them and the first digit is ear-level speakers, the second the subwoofer, the third overhead speakers. Dolby also has a separate 5.1.2 page that uses Dolby Atmos-enabled speakers instead of overhead ones.
Wi-Fi 7 beats 6E for exactly two reasons: channel width doubles to 320MHz and each subcarrier carries 12 bits instead of 10. Multiply and you get 2.4x. But 4K QAM needs roughly 42dB SNR, so it only switches on close to the router.
Samsung rates its foldable hinge for 200,000 open-close cycles, which it frames as about five years at 100 folds a day. Change the daily count and the answer swings from 2.7 years to more than 18.
In Korea Consumer Agency testing of 13 humidifiers, hourly output ranged from 182ml to 606ml — a 3.3x spread — while annual running costs differed by more than 40 times. The technology is what splits them.
Multiply the screen diagonal in inches by 4.13 for the recommended distance in centimetres. A 65-inch set wants 268cm at the SMPTE standard and 198cm at the immersive one — which is why the same 2.7m room justifies either 65 or 89 inches.
Copilot+ PC requires an NPU of 40 TOPS, 16GB of RAM and 256GB of storage. The New Galaxy Book6 launched on 1 September lists up to 15 TOPS on published specs, against 49 TOPS on the standard model of the same series.
Thunderbolt 5 guarantees an 80Gbps link and 64Gbps of PCIe through certification; USB4 only has to clear 20Gbps to meet spec. The headline 120Gbps is four lanes redistributed 3:1, not a faster pipe.
A projector labeled 8,000 lumens measured 251 lux while a 200 ANSI-lumen model hit 477 lux. What ANSI lumens actually measure, why plain lumen ratings cannot be compared, and how many lumens each screen size needs.
The cabin limit for power banks is 160Wh, roughly 43,000mAh. Since 20 April 2026 it is two units per passenger, and in-flight charging is banned. Here is the mAh-to-Wh maths behind it.
A PCIe 5.0 SSD reads sequentially at 14,800MB/s, roughly double a Gen4 drive. Measured game load times differ by under 0.2 seconds. Here is the bandwidth, heat and endurance math that explains the gap between the two facts.
