  Idk if it’s just me but I have pretty good hearing, so I can hear the high pitch tone CRTs make and it drives me crazy.

    This only happens with TVs or very low quality monitors. The flyback transformer vibrates at a frequency of ~15.7k Hz which is audible to the human ear. However, most PC CRT monitors have a flyback transformer that vibrates at ~32k Hz, which is beyond the human hearing range. So if you are hearing the high frequency noise some CRTs make, it is most likely not coming from a PC monitor.

    Its a sound thats a part of the experience, and your brain tunes it out pretty quickly after repeated exposure to it. If the TV is playing sound such as game audio or music it becomes almost undetectable. Unless there is a problem with the flyback transformer circuit, which causes the volume to be higher than its supposed to be.

      There is not one crt I ever encountered that I couldn’t hear. So I’m having trouble believing you information.

        en.m.wikipedia.org/wiki/Flyback_transformer

        Under “Operation and Usage”:

        In television sets, this high frequency is about 15 kilohertz (15.625 kHz for PAL, 15.734 kHz for NTSC), and vibrations from the transformer core caused by magnetostriction can often be heard as a high-pitched whine. In CRT-based computer displays, the frequency can vary over a wide range, from about 30 kHz to 150 kHz.

        If you are hearing the sound, its either a TV or a very low quality monitor.

        Either that or you’re a mutant with super ears and the US military will definitely be looking for you to experiment on.

        I could hear them too, when I was younger. I lost that frequency range of my hearing in my mid-to-late 20’s, which I’ve read is normal.

      Oh neat, thanks for the explanation! That makes sense as most of my crt exposure for the past 10 years has been classroom TVs and museum exhibits.

    the solution is to be in your mid-30s

      Unless you have tinnitus.

      Then you’re possibly going to hear it very frequently.

        you could say in a…

        high frequency

    For me it was the refresh. If a CRT was at 60Hz, I could see it flashing when I wasn’t looking directly at it. I had to have it set to at least 75 Hz (>80 Hz preferably) or it would give me a headache.

    This and the scanlines actually make it feel so weird to look at for me, I hate crts with a passion

  You beat me to the punch.

  We were absolutely considering output delay and hoarding our CRT monitors.

  Some of us were also initially concerned about input delay from early USB until we were shown that while it is slower that it was unnoticeable.

    I forgot that! PS/2 mice and keyboards were hoarded.

  I bought a Sun Microsystems 24" widescreen CRT for $400 on eBay back in 2003ish? iirc. It was 100lbs and delivered on a pallet lol. There’s a reason why they didn’t get very big and were mostly 4:3. 1920x1200 and like 30" deep! But, they did exist!

    I know it. I myself have 2, a 1981 JVC UHF/VHF radio 4.5", and a Sylvania 27" with a DVD/VHS combo unit built into it.

    They even made a curved ultrawide CRT once, surprisingly. Though it cost a fortune when it came out.

    source
• SpaceCowboy@lemmy.ca ⁨2⁩ ⁨weeks⁩ ago

  Yeah, right?

  The fact that we know about this decades later is because people actually did care about it.

  When LCDs (then later LEDs) improved this concern kinda faded away. Which makes sense.

  On this note, anybody know where I can get a 1600x1200 crt these days?

  source

  • HackerJoe@sh.itjust.works ⁨2⁩ ⁨weeks⁩ ago

    ebay? If you can get an IBM P77 or Sony G220 (they are the same) in good working condition you should be golden. Those are awesome. They go up 170Hz, 75Hz at 1600x1200. And can even do 2048x1536 although that would be out of specs and only 60Hz (barely usable but fucking impressive).

    • RightHandOfIkaros@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

      You will 100% overpay if you get one on eBay. Best place is to try asking businesses, schools, or local news stations if they have old CRTs you can look at they’d be willing to sell to you. News stations preferrably since they usually had very high quality BVMs.

  It even took some weird proportions where “pro” gamers set their game to display 4:3 on their widescreen lcd.

  Habits die hard.
