  • Many of those types while having great brightness and reduced image burn in actually have terrible quality images. Eg no hdr, some may only be 30hz, some may have the contrast ratio which is so low you’ll just be sad to watch a movie on it looking at a black grey mush.

    Though like all things, there’s a gradient. Some of the conference room monitor panels can be better but often >3x more expensive than the consumer model due to much better warranty (eg same day parts).

    So I don’t have any advice here, just a bit of warning with experience with being around zoom, teams, and display walls from an IT solutions perspective,though generally I use AV partners for model selection and installation on any meaningfully sized conference/boardroom room or special application eg stages.


  • Look it depends on the age of the car, but let’s take an old manual car for example.

    On those cars, there’s a fuel map to rpm. There’s actually a few maps including throttle and ignition timing. But think of a spreadsheet of rpm and fuel at a certain throttle load.

    At 0 throttle: The map says to stop the engine from stealing at under say 800 rpm it needs to have fuel added at rpms lower than that to speed up the engine to avoid stalling. At 800rpm it needs a consistent amount kind of a known amount that keeps it in equilibrium. At over 800rpm it needs less fuel the more rpm it has over the idle 800rpm until it’s zero fuel.

    And you’ll feel that, you’ll feel that moment the car starts adding fuel because if you’re only engine braking to a stop your car will get near that idle rpm and your engine will start adding power to avoid a stall, and your braking will diminish.


  • If you take an engine out of a car and try to spin it by turning the crank shaft, it will be hard to turn because the cylinders need to compress air (it’s required before adding fuel and spark to explode that compressed air so it expands).

    When that engine is in the car, and you don’t add fuel and spark, then the cars wheels have to turn the engine and compress that air, thousands of times per minute. That force that the wheels have to send to the engine to spin that engine slows you down.

    I’m thinking you think the engine itself has a brake on it… No.
