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 3 жыл бұрын

@@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 16 күн бұрын

even more impressive is that since 60hz is just barely slow enough to be flickery when viewed in computer monitor distances, crt monitors often ran even faster than that, often running at 75hz by default but some running at 85hz or higher!

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.

@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.

Electron beams don't have any colors. Its actually screen coating which produces colors.

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

@thomase13 8 жыл бұрын

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 Жыл бұрын

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

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.)
