Cool, i always wondered whether there were multiple electron guns or if the one was used. That's incredibly fast when you think about. THe one gun deflects to refresh every "cell" 60 times a second. Seems remarkably accurate. Thanks for sharing.

[@rasmussenrambles8576]

@@monkeycoder7368 Hi. I am currently studying electron microscopes, which uses essentially the same technology. The early electron microscopes, thus I would assume this holds true for early CRT as well, used Wolfram/Tungsten for making the filament. It later moved on to LaB6 The difference in colours? Red colour is 1,8 eV and Blue colour is 3,1 eV, so the difference would be how much energy is sent into the filament Keep in mind that their 3d model is very simplified and does in fact lack some components

[@churipputori9087]

They mention 60 FPS for simplification, but the field rate was actually 59.94, PAL regions were lower at 50 FPS, and higher end CRTs could go up to 121Hz. That's 121 passes a second. Fun fact: CRTs displayed interlaced images by default to reach 60fps, so 240p combined every other field of 480i and cut the FPS by half, giving us the 30fps of 80's and 90's video game systems.

how is it possible only 3 light emitters to light all the pixels on the screen and do that 80 times per second

[@monkeycoder7368]

mask mix the light red green blue

[@insertx2k_dev]

it's due to the Hz (Hertz) , it's how many the 3 Electronic guns produces the RGB colors per one second For an example ,My CRT Monitor , works at 1280x1024 At 60 Hz And that means , the three electronic guns produces the RGB Colors 60 Times per second at 1280x1024 Resolution And the maximum supported resolution is due to the Shadow mask rendering ability

[@alexhanson449]

The magnets don't physically move, they use electromagnetic coils, which vary the magnetism by the amount of electric current applied. This change in magnetism causes the electron beam to bend in different directions

And i tout that pc crt monitors were progressive, but i am wrong because it generates the image line by line, but it happens sooo fast that we just see a complete image.

[@SOEINEGAUDI]

it is progressive ! interlaced would mean that every second line would be skipped from frame to frame. you could have and array of small leds that can all flash up at the exact time, and make it display interlaced video. what you are thinking of, is rolling shutter. if you have a decent camera it will shoot 1080p (progressive) but most likely the pixels will also be collected line by line, but because of the p no line will be skipped

[@Benign441]

@BranislavDJ The older black and white screens had little protection and have caused many cancers and deaths. Tv repair was a dangerous job! They have since realised the issue and put radiation protection in tv's. What happens is the larger tvs need a stronger electron beam and a more powerful yoke, sometimes and 30k volts(reason why 26" was a plateau)!! Lots of x-rays! However, even with all the protection, if you held x-ray film in front of any TV, over time, you would see a result.

[@drummergirl4239]

Its happens so fast that you are unaware of the firing process and the result is a steady picture Rolling shutter effect: we’ll see about that

[@jeehoonlee8118]

[@idkrossplay]

Oleds were around in 1987 so this video was made way after those became a thing

[@gabrielphilips6980]

if you have 1million pixels and use 60hz, so the gun can switch targets 60million times per second?

[@goustune]

but why could we change resolution that easily ? With LCD screen, it's almost not possible, I mean the quality becomes really bad.

[@horseradish843]

What are you even saying?

[@Beam_Teamer]

lol ikr it didnt make any sense

[@thomase13]

Because a colour CRT is only limited by the number of phosphors / holes in the shadow mask or aperture grille, and there are (I am told) many more phosphors than there are pixels. Hence, a quality CRT can resolve any way you like! I remember the last CRT monitor I had (which came with my 2002 Dell Dimension), which I believe was 17 inches. It was not the highest quality monitor, and while it worked fine at its native XGA (1024x768), it really did look blurry at VGA or SVGA (640x480 or 800x600) Thankfully, I have an IBM ThinkVision C170 CRT in the mail, which can apparently display up to 1600x1200! (more than ample for my purposes!)

[@idkrossplay]

Because crts have a maximum output range in khz, but no native resolution. An lcd has a native resolution and any other resolution is just upscaled to your monitor's native resolution

[@crustycorollas]

Interesting

[@BranislavDJ]

@warzinc B&W perhaps. There are laws that regulate this. 0.5 milliroentgens per hour is minimum.Most TVs produces far far less.

[@IzludeTingel]

For retro gaming, only ever a CRT. Don't bother with xRGB scalers unless you dig artificial scan lines and no light guns. If you want luxury, go with a PVM. For affordability, get an RGB modded Trinitron TV. For PC gaming, SONY has a 1080p CRT PC monitor (GDM-FW900). But for practicality and affordability, a 4k Vizio TV for living room PC gaming setups is ideal. I have tasted oLED and it tends to have issues... Definitely not gamer friendly (almost every oled washes out be it months or short years later.)
