why did no one tell me about this sooner?? i've been killing my eyes for years thinking it's normal for computer screens to be a pain to look at. what the hell
You probably had a defective monitor, even ones with 240Hz PWM don't cause any kinds of problems if brightness is at 50% or higher.
Gabriel Walker
You were using a CRT monitor, weren't you, OP?
Justin White
CRTs don't use PWM to control brightness, so no, they wouldn't be.
Isaiah Green
>using a 2nd year electrical engineering concept to control brightness on a sensitive device
Whoever designed your monitor should be hanged
Tyler Richardson
no a hp lcd
Christopher Ramirez
Absolute majority of monitors use it.
Robert Lopez
i only have one over the kitchen sink
Landon Gray
Yeah, low-frequency backlight PWM is bullshit. I don't have a severe reaction to it like you, OP, but it's distracting when you rapidly move your eyes across the screen and it makes my eyes tire more quickly. With LED backlights PWM is a low more noticeable than with old CCFL backlight screens. All ThinkPads with an LED backlight have it, I think, but at least you can tune the frequency. When I set mine to over 500 Hz it became a whole lot nicer to use.
PWM is one of the reasons I don't welcome AMOLED screens. So far nearly all of them have had 240 Hz PWM.
Austin White
Are you sure you don't need glasses kek this sounds like how I used to be before getting them.
Connor Morales
I've been looking at a monitor at least half a day for the past 10 years and never had any issue.
Christian Collins
What kind of stupid logic is that?? >its simpel >cweator shuwd die
Christopher Ramirez
Same. I can browse for 9999 hours no issues. 3D games on the other hand will destroy my eyes in less than 30 minutes and no, this isn't a blue light problem. Really need to stop playing games.
Brody King
IPS, led backlight, no PWM (or only there in uselessly low brightness, then you stay above the pwm point).
That's the way to go.
Christian Russell
IPS, CCFL backlight, no PWM FTFY
Joshua Mitchell
>CCFL There's literally nothing they offer over LED backlight. CCFL do not last as long, do have implicit blinking, are less power efficient, and make the monitor way thicker and clunkier.
Sebastian Reed
>There's literally nothing they offer over LED backlight. No blue light cancer isn't enough of an advantage? >CCFL do not last as long There are CCFL monitors with 25k+ hours doing just fine out there. I'd love to see an LED monitor do that. >do have implicit blinking The phosphor persistance inherent to the tube coating effectively removes backlight flicker, at least in good monitors >are less power efficient You're right on that one. Though I think it's an acceptable tradeoff >and make the monitor way thicker and clunkier And why would you care about those things when using a desktop monitor?
Ian Young
>No blue light cancer isn't enough of an advantage? A very wide spectrum in the source of light is necessary for being able to produce a wide gamut of colors on the IPS layer. No "blue light cancer" nonsense. The colors you get are within visible range, and if you want to restrict the color space, you can do it either on your computer or on the display's own postprocessing.
Nathaniel Powell
and if you want to restrict the color space, you can do it either on your computer or on the display's own postprocessing. Imagine being so stupid you think the color filters on your monitor are narrowband enough to remove harmful blue wavelengths without causing degradation to the overall color balance of the picture. >yeah, I like my monitor looking like piss just so it can be thinner and use 10W less That's how you sound like
Cooper Morales
You can't get the wide gamut otherwise, moron.
Ian Hill
>i've been killing my eyes for years thinking it's normal for computer screens to be a pain to look at. what the hell Its good you found out why but why would you think that? I had problems when I first started using a computer but adjusting gamma/brightness/profiles fixed it for me. If your eyes ever feel strained (not completely relaxed) you need to adjust brightness, font size, and colors. You should probably do those anyway.
Justin Kelly
>hp There's your problem.
Jordan Stewart
It's simple and it's also shit for this specific application. So it's irresponsible and lazy for a designer/engineer to use it instead of coming up with a solution that's better suited for the application.
Dylan Collins
f.lux is a great program if you're not too scared about being spied on too help your eyes
Jackson Torres
>3D games on the other hand will destroy my eyes in less than 30 minutes and no get 240hz
Isaac Allen
I have a 144hz screen right now. What's the reasoning behind your advice if you don't mind?
Joseph Jenkins
Simple does not mean good. In this case it's a simple and horrid solution that shouldn't be used period.
