If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
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.
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.
I could time it out most of the time, but it was always there.
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.
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.
Not sure you follow: even if the primary frequency is out of range, a harmonic (half the frequency, quarter the frequency, etc) can simultaneously exist with the primary.
I suppose its possible with a low quality CRT that has poor construction, leaving loose parts or thin plastic fins that can vibrate at harmonics of a lower frequency, but high quality CRTs don't have this issue.
Extra or louder noise does not occur in normal operation of a correctly functioning flyback transformer circuit. Any frequency or harmonic (vibration) that occurs that is not the specified frequency of operation of the flyback transformer is caused by a problem in the circuit. A brand new CRT with known good parts will not have any kind of extra harmonic.
I had to replace a flyback transformer because it was too loud, and it was a pretty simple job. Hardest part was finding a new flyback transformer. After replacement, the noise volume was reduced to normal levels.
It's crazy you keep ignoring what he's saying to double down and triple down on your incorrect claim.
I remember CRTs being washed out, heavy, power hungry, loud, hot, susceptible to burn-in and magnetic fields... The screen has to have a curve, so over ~16" and you get weird distortions. You needed a real heavy and sturdy desk to keep them from wobbling. Someone is romanticizing an era that no one liked. I remember the LCD adoption being very quick and near universal as far as tech advancements go.
As someone who still uses a CRT for specific uses, I feel that you're misremembering the switch over from CRT to LCD. At the time, LCD were blurry and less vibrant than CRT. Technical advancements have solved this over time.
Late model CRTs were even flat to eliminate the distortion you're describing.
I had a flat CRT. It was even heavier than a regular one.
I miss the sound of the degaussing function.
Schdoing !
I like how no one mentions that CRT pixels bleed into each other.
And it worked as AA wasn’t as important in that “fuzzier” screen when graphics aren’t as good as they are today.
Are you sure it was CRT technology? Because bear in mind, colour CRTs had to focus the beam so accurately that it only hit the specific "pixel" for the colour being lit at that time. What there was, was blur from bad focus settings, age and phosphor persistence (which is still a thing in LCD to an extent).
What DID cause blur was the act of merging the image, the colour and the synchronisation into a composite signal. All the mainstream systems (PAL, SECAM and NTSC) would cause a blurring effect. Games on 80s/90s consoles generally used this to their advantage, and you can see the dithering effects clearly on emulators of systems from that period. Very specifically, the colour signal sharing spectrum with the luminance signal would lead to a softening of the image which would appear like blurring. Most consoles from the time only output either an RF signal for a TV or if you were lucky a composite output.
Good computer monitors (not TVs) of the time were extremely crisp when fed a suitable RGB signal.
plasma TV?
Plasma TVs had burn-in problems, especially with cropped content with black bars.
It was a dark day for gamers when the competitive things crawled out of their sports holes.
I think most people that were gaming held onto their CRTs as long as possible. The main reason being, the first generation of LCD panels took the analogue RGB input, and had to present that onto the digital panel. They were generally ONLY 60hz, and you often had to reset their settings when you changed resolution. Even then, the picture was generally worse than a comparable, good quality CRT.
People upgraded mainly because of the reduced space usage and that they looked aesthetically better. Where I worked, we only had an LCD panel on the reception desk, for example. Everyone else kept using CRTs for some years.
CRTs on the other hand often had much better refresh rates available, especially at lower resolutions. This is why it was very common for competitive FPS players to use resolutions like 800x600 when their monitor supported up to 1280x960 or similar. The 800x600 resolution would often allow 120 or 150hz refresh.
When LCD screens with a fully digital interface became common, even though they were pretty much all 60hz locked, they started to offer higher resolutions and in general comparable or better picture quality in a smaller form factor. So people moved over to the LCD screens.
Fast-forward to today, and now we have LCD (LED/OLED/Whatever) screens that are capable of 120/144/240/360/Whatever refresh rates. And all the age-old discussions about our eyes/brain not being able to use more than x refresh rate have resurfaced.
It's all just a little bit of history repeating.
It's ok, if anyone wants them back the smash brothers melee community has them all in the back of their car
Can someone please explain why CRT is 0 blur and 0 latency when it literally draws each pixel one-by-one using the electron ray running across the screen line-by-line?
The guy inside it drawing them is insanely fast at his job. That's also why they were so bulky, to fit the guy who does the drawing.
Because it is analog. There are no buffers or anything in between. Your PC sends the image data in analog throug VGA pixel by pixel. These pixels are projected instantly in the requested color on the screen.
And no motion blur because the image is not persistent. LCDs have to change their current image to the new one. The old image stays until it’s replaced. CRTs draw their image line by line and only the the last few lines are actually on screen at any time. It just happens so fast, that, to the human eye, the image looks complete. Although CRTs usually do have noticeable flicker, while LCDs usually do not.
No such thing as instant. There is always some latency.
Well yes, the speed of light in this case.
Because it draws those "pixels" as the signal reaches the monitor. When half of a frame is transmitted to a CRT monitor, it's basically half way done making it visible.
An LCD monitor needs to wait for the entire frame to arrive, before it can be processed and then made visible.
Sometimes the monitor will wait for several frames to arrive before it processes them. This enables some temporal processing. When you put a monitor in gaming mode, it disables (some of) this.
If that's how TFTs worked we wouldn't have vsync settings in games.
0 input lag lmao
Just goes to show many gamers do not infact know what "input" lag is. I've seen the response time a monitor adds called input lag way to many times. And that mostly doesn't in fact include the delay a (wireless) input device might add, or the GPU (with multiple frames in flight) for that matter.
First rule at our LAN parties: You carry your own monitor.
We'd help each other out with carrying equipment and snacks and setting everything up. But that big ass bulky CRT, carry it yourself!
Not necessarily if you’re the one walking in with the DC++ server. Getting that thing up and running was suddenly priority #1 for the entire floor.
