WEBVTT 00:00:00.599 --> 00:00:10.080 there are plenty of things in the PC Enthusiast space that people love to 00:00:06.200 --> 00:00:13.679 argue about AMD versus NVIDIA AMD versus 00:00:10.080 --> 00:00:16.840 Intel AMD versus the 1980 US Olympic 00:00:13.679 --> 00:00:19.480 hockey team okay but seriously aside 00:00:16.840 --> 00:00:24.480 from these more practical concerns Aesthetics are just as important to many 00:00:22.760 --> 00:00:30.679 people with there being no real consensus as to what looks good after 00:00:28.160 --> 00:00:36.440 all what's tacky to one you proder might be Michelangelo's David to another so in 00:00:34.120 --> 00:00:41.079 the past few years many component manufacturers have decided hey why not 00:00:39.360 --> 00:00:47.280 just give people the ability to customize the look of their battle 00:00:42.800 --> 00:00:50.239 station on a whim by adding RGB lighting 00:00:47.280 --> 00:00:56.719 the RGB craze mostly started out on keyboards and mice but these days you 00:00:53.640 --> 00:00:59.280 can pick up motherboards CPU coolers and 00:00:56.719 --> 00:01:05.199 even RAM sticks that claim to offer Millions of colors but how does all of 00:01:02.480 --> 00:01:09.280 this work and what features should you be looking for if you're going to trick 00:01:07.240 --> 00:01:14.520 out your rig like The Griswalds Christmas tree well if you think back to 00:01:12.040 --> 00:01:20.040 kindergarten you might remember that the three primary colors that combine to 00:01:17.040 --> 00:01:21.159 form all the other colors are red yellow 00:01:20.040 --> 00:01:27.200 and blue but this is true only for pigments 00:01:24.720 --> 00:01:33.880 light works a little differently with the three primary colors of light being 00:01:29.960 --> 00:01:36.439 red green and blue hence the name 00:01:33.880 --> 00:01:42.840 RGB so when you fire up your favorite RGB device what's happening is that 00:01:39.759 --> 00:01:45.759 separate red green and blue LEDs are 00:01:42.840 --> 00:01:51.159 lighting up at different intensities to produce different colors as there 00:01:48.360 --> 00:01:55.719 currently isn't a single LED bulb that can cycle through different colors on 00:01:53.320 --> 00:02:00.240 its own so there are a couple of different ways that you can see this 00:01:57.680 --> 00:02:06.039 principle in action if you set your favorite RGB device to White you might 00:02:03.039 --> 00:02:08.920 be able to see all three colored LEDs 00:02:06.039 --> 00:02:13.440 lit up if you look closely enough this is the same reason that when you get a 00:02:11.000 --> 00:02:20.879 drop of water on your phone screen you can see a rainbow like effect on white 00:02:16.080 --> 00:02:23.480 spots neat huh but how do these devices 00:02:20.879 --> 00:02:29.319 adjust the brightness of each led to produce the color you want well usually 00:02:26.599 --> 00:02:35.560 RGB gadgets work with a technique called pulse width modulation or pwm which you 00:02:32.920 --> 00:02:40.680 can learn more about here although you might be more familiar with pwm as a way 00:02:38.720 --> 00:02:46.840 to control your fan speed in your computer the same concept can control 00:02:43.720 --> 00:02:50.239 colored LEDs so when you want to tell 00:02:46.840 --> 00:02:52.400 your Control software boom I want yellow 00:02:50.239 --> 00:02:58.519 it sends a signal to your device that tells both the red and green LEDs to 00:02:55.720 --> 00:03:03.760 light up and blue to sit down and shut up and PW w m also controls something 00:03:01.720 --> 00:03:10.760 called the duty cycle essentially how long the light is 00:03:06.959 --> 00:03:14.040 on during each refresh a shorter duty 00:03:10.760 --> 00:03:16.000 cycle means that specific color of LED 00:03:14.040 --> 00:03:20.840 will be dimmer so if you want your keyboard to be a highlight or yellow 00:03:18.080 --> 00:03:26.120 sort of color your green and red LEDs will have longer Duty Cycles while your 00:03:23.200 --> 00:03:30.720 blue LEDs will have very short Cycles or just be turned off completely but 00:03:28.720 --> 00:03:37.200 depending on its imp M mentation especially if the LEDs are refreshing 00:03:33.159 --> 00:03:39.760 too slowly using pwm control with equal 00:03:37.200 --> 00:03:44.640 parts of red green and blue to achieve white can result in a distracting 00:03:42.200 --> 00:03:50.239 rainbow effect similar to what some people experience when watching a single 00:03:46.680 --> 00:03:53.560 chip DLP projector to compat this some 00:03:50.239 --> 00:03:57.400 manufacturers are introducing rgbw 00:03:53.560 --> 00:03:59.680 strips that have entirely separate white 00:03:57.400 --> 00:04:05.760 LEDs but enough about the nuts and B bolts what should you actually look for 00:04:02.280 --> 00:04:07.760 when buying RGB gear well perhaps 00:04:05.760 --> 00:04:11.720 unsurprisingly this depends almost entirely on your personal preference as 00:04:10.159 --> 00:04:17.120 long as you buy something of good quality an important thing to research 00:04:14.159 --> 00:04:23.400 is what kinds of customization a certain RGB product offers as many manufacturers 00:04:20.359 --> 00:04:25.759 bundle software that can control RGB 00:04:23.400 --> 00:04:32.400 effects which may or may not be to your liking Hardware Solutions also exist 00:04:29.120 --> 00:04:35.320 such as NZXT Hue plus which serves as a 00:04:32.400 --> 00:04:39.320 central hub for your systems LED strips and the RGB headers on certain 00:04:37.639 --> 00:04:44.680 motherboards which provide similar functionality through software to take 00:04:42.240 --> 00:04:50.080 things a step further unified RGB ecosystems like ASUS Aura and Razer 00:04:47.479 --> 00:04:54.320 chroma are starting to become popular allowing you to sync up RGB effects on 00:04:52.360 --> 00:05:00.000 your lighting strips your motherboard your memory your fans or even supported 00:04:56.880 --> 00:05:02.320 peripherals and room lighting and 00:05:00.000 --> 00:05:07.080 considering that RGB LEDs can often be configured to change colors depending on 00:05:04.919 --> 00:05:13.280 important variables such as system temperatures your perfectly harmonious 00:05:09.680 --> 00:05:15.880 RGB setup can actually be functional as 00:05:13.280 --> 00:05:20.680 well just make sure you don't go too crazy want to browse a more open 00:05:18.400 --> 00:05:25.680 internet and use online services as though you are in a different country 00:05:23.039 --> 00:05:30.240 anonymously check out tunnel bear they've got easy to use apps for iOS 00:05:28.120 --> 00:05:36.919 Android PC and Mac they also have a Chrome extension and turning it on is as 00:05:33.280 --> 00:05:38.960 simple as clicking a
