Comment by RightHandOfIkaros@lemmy.world on Anon reflects on e-sports

People did care, which is why people who played games competitively continued to use CRT monitors well into the crappy LCD days.

Heck, some people still use CRTs. There’s not too much wrong with them other than being big, heavy, and not being able to display 4k or typically beeing only 4:3.

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.

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.

the solution is to be in your mid-30s

Unless you have tinnitus.

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

eeeeeeeeeeeeeeeeeeeeeeee

and here i’d been blissfully unaware of it for days now. damn you all.

(wear earplugs to concerts kids, especially if you’re playing)

you could say in a…

high frequency

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.

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.

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

I could time it out most of the time, but it was always there.

https://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. Human hearing in perfect lab conditions can only go up to about 28kHz, and anything higher is not able to be heard by the human ear.

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

I’ll defend this guy: there can easily be a harmonic at half the flyback frequency that is audible. It’s lower amplitude so less loud, but I could believe someone being able to hear that.

Yes, as I previously stated, if there is a problem with the flyback transformer circuit, it is possible that the frequency or volume of the noise it generates can become increased or different.

Though again, PC monitors never made an audible noise unless they were low quality and used the cheaper 15.7kHz transformer in their construction.

Other noises associated with CRTs are the degaussing noise, which only happens once usually after turning on the CRT or after pressing the degauss button, or the sound of old IDE hard disks spinning, which also make a constant high frequency noise.

Please don’t tell them about me.

Your secret is safe with me.

On a side note, I can also hear when a capacitor is going bad on an lcd when other people around me cant hear it.

It could be something else in the crts I’m hearing, but I can definitely tell one is on without seeing it. It’s been like this since the 70s for me.

I can also smell and taste things other people can’t, so something is a little different in my brain somehow.

My partner and daughter tell me I have super powers lol. Guess who gets to smell meat for rot? Not them! Bleh.

You’re not alone, I can hear CRTs, bad capacitors and an array of other electrical appliances.

I can still hear the high frequencies that only teenagers and your kids are meant to be able to hear.

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.

eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

(me too)

Ditto, lcd’s were a godsend.

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

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.

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.

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

Habits die hard.

They do hum and buzz.

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

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).

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.

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.

This is a place to share greentexts and witness the confounding life of Anon. If you’re new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

Anon is often crazy.
Anon is often depressed.
Anon frequently shares thoughts that are immature, offensive, or incomprehensible.

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
