....can anyone who has used it at 90Hz comment on the quality of such an improvement? Is the change noticeable? Is it beneficial?
Before we get into that, can people actually distinguish between 90Hz and the device simply being faster? I.e. would it have been a much better experience at 60Hz also?
Higher framerate could be beneficial in certain kinds of games. I don't think most people would notice or care, though. This isn't the days of the CRT where a low refresh rate meant you were staring at a blinking light bulb that would give you a headache over time.
Walking around your kitchen, lit by a fluorescent light, you're seeing real life at 60 fps.
For fluorescent light, it ends up being 120 Hz (fps). While the voltage has positive and negative peaks that make up one period, that ends up being two energy peaks as far as the bulb is concerned. (Have had to filter this out when doing light diode projects in the past.)
Folks (including me) who complain about fluorescent lights flickering are actually complaining about the ballast not keeping the bulb energized, which happens at a much lower (and irritating frequency). (That can happen for any number of re
Folks (including me) who complain about fluorescent lights flickering are actually complaining about the ballast not keeping the bulb energized, which happens at a much lower (and irritating frequency). (That can happen for any number of reasons: cold, old bulb, ballast going bad, etc.) I greatly prefer LEDs these days (which are either DC or kHz range on the switching power supply).
The ballast does not keep the fluorescent tube "pwoered". Its purpose is to limit the power drawn by the tube. It's a giant in
