From something like 20/20Mbps, to a faster speed, to an even faster speed, to the full 1/1Gbps I'm using today at really no extra cost.
#FLICKERY THOUGHTS FREE#
For years my ISP has been coming back to me and saying 'hey, we have more bandwidth that we thought, here's a free upgrade'. Granted I'm lucky to live in an area served by non-profit muni fiber, but it does illustrate what can happen if data is handled like a utility and not held hostage by corporations. My ISP bill has gone down by a couple bucks each month.

The Pro of Iris is that it costs less than a sandwich and the basic things are actually in the free version which you can use forever for free.Hmmmm. The Pro of flicker-free monitors is that even at minimum brightness the colors of the screen are calibrated and accurate. At maximum brightness cheap monitors and flicker-free monitors are basically the same. Both Iris and flicker-free monitors do the same thing.įlicker-free monitors still flicker, but they flicker at high frequency at both high and low brightness levels. The design of the circuit is more complicated and they are more expensive. They just use something called DC dimming instead of PWM.ĭirect current dimming is what the modern flicker-free monitors use. You probably have heard about this new flicker-free monitors. You can achieve something similar by placing black transparent overlay on your screen, but this way you will change the contrast of the screen and it will be harder to read on it. The second good thing about Iris brightness is that it will not change contrast of the screen. It’s not cure for everything and the best possible solution will be for me to start to make E-ink monitors, but it’s better than changing the flicker frequency. Yes, this will make your colors look a little bit more darker, but you will not feel eye pain. Basically instead of changing the frequency of the backlight, Iris is changing the white point of the monitor. Iris is using the video card to control the brightness. Well to fix this problem I created special type of brightness reduction into Iris. Go and try and see the eyestrain after only a minute. For the eye it’s like turning the lights in your room ON and OFF hundred of times per second. If you need even less power consumption you lower the frequency of the backlight even at maximum brightness. If you want to make it cheap you need to use PWM, if you want less power consumption you need to use PWM. Basically this means that to control the brightness you make the flicker frequency of the monitor lower and you get not so bright display. Well the solution to make the cheapest and the long lasting monitor is to use PWM to control the brightness. The goal of monitor manufacturer is to make energy saving and cheap monitors.
The problem is PWM or the so called Pulse-width modulation and let me explain why. On maximum brightness most monitors have flicker rate with really high frequency and the iris of the eye will not start to synchronize with the ON and OFF cycles of the backlight. The only way to completely eliminate the flicker from your electronic devices is to use E-ink or to not use electronic displays at all. Every modern display uses some kind of LED, OLED, LCD and every other monitor technology used today. This is normal, because the way semiconductors work requires them to turn ON and OFF in order to work properly. All monitor have some kind of flicker rate.
