minus-square@[email protected]linkfedilink4•1 year agoHow does the circuitry behind №2, 3, and 5 work?
minus-square@espentanlink2•1 year ago“15,000 times per second”, yeah, right. With a refresh rate of 60Hz, even if possible it would be pointless. All of those sound like marketing gibberish. #5 sounds like surge protection, so there might be something to that one.
minus-squarelobsticle 🦞link6•1 year agoThe horizontal refresh rate of NTSC was 15735 Hz, so the adjustments are likely tied to that particular signal. Definitely marketing fluff for sure, but backed up by the tech.
minus-square@[email protected]linkfedilink2•1 year agoI don’t think number 3 is circuitry. From the description it is probably a big metal shield around the tuning circuitry.
