I get a lot of people going with the 'You can not see more then 60Hz' comment they throw out. Infact almost everyone can, but it's how we see it.

To perceive motion through still pictures, it takes ~ 25 frames per second (FPS). This is what even Blu-Ray movies are encoded with. Our average computer monitors lock to 60Hz which in turn limits the maximum to 60FPS.

If you do anything over HDMI, you also only see 60FPS, however internals in the display unit can make things appear smoother then they are. LGs are especially nice to do this with their 240Hz units in my experience.
So what does this mean to the average Joe? Nothing. A lot of people don't see it nore care. However there are some of us that can easily see it but use it either way and the extreme few of us like myself who can actually be caused pain by the slow display of old.

In the living room we have a 120Hz Vizio. Obviously it still only gets the ~25 frame signal and tries to do it's own internal 'smoothing' to make it more fluid to the user. Works so-so. The LG we have in the bedroom works beautifully on that note.

But what do 'I' see? My whole life I wondered why people tolerated the horribly 'strobey' world. All of the fluorescent lights in the US have a 60Hz light frequency, so as you might see them as a solid light, I see them as a fast strobe light. It's just how they work. I HATE them. And they are still everywhere.

My home has converted over to high-speed LED lighting and it helps me a ton. Old-school incandescent lights can be OK depending on what they are exactly but also tend to be the wrong color for myself. I prefer the daylight spectrum so I can see colors more accurately (which is ironic when I have blue/green issues anyhow).

ANYHOW; back to the monitors... So people want super-fast stuff and other people argue that you can't "SEE" it... Parts are both right. Your brain might only be able to identify ~ 60 FPS individually, but it's HOW your brain puts them together that makes all the difference. If you speed up the input and let your brain pick the frames it is most comfortable with, I think it is happier and less stressed as in my situation. However if you force your chosen 60 on it, some, maybe many, people won't notice but it becomes an issue for the sensitive.

Plus, I've had these same people over to my house on my computer which is actually setup for 144Hz live use. They watch me spin up some game (my system can do just about any of them at this speed) and the response is always 'OMG!'. I've never had anyone say it just looks like everything else. Even just grabbing a window and doing a circle, it's so smooth. The simplest things become almost fluid.

FOR ME, this means no more migraines. On the monitor I stare at all day/night long in most cases, now I can without extra pills and sleeps to make the headaches that put me in bed for DAYS go away.

However, this is my special corner of the world... And even I have a few 60Hz monitors in the house. I.E. my phone, etc. Some of them do use internal smoothing techniques to help. My Galaxy S4 isn't as bad as I thought it might be which is great. But I still can't stare it it endlessly with moving video on it.

On my desk I have my 144Hz ASUS monitor front and center, and two support monitors for my servers off to the side. Both of those are used more rarely. I'll play a movie on one while I work but I'm really listening to it and it's brightness is so detuned as to barely leave any glow at all or the flicker itself would get to me. It's just what I had at the time and now too broke to do any better.


GPUs aren't > 60Hz friendly. I recently went through TWO 7970's and gave them away after the fact as my giveaways (when I had money) and they never could handle the faster refresh rates without a full-on snow effect on the monitor.

I went with my now GTX 690 (was a pair of Titans but needed the $ so sold them off and went backwards a bit) and it does everything great accept Windows Media Center (which Nvidia is currently investigating!).

But the end results are games that are so smooth... Videos that are nice using smoothing software to fill in the frames like some newer display units do, etc. Which is still why I listen to more movies then I watch anymore as this is getting worse with age.


Even the extremists in the world agree that the 120Hz (actually the 85Hz range) is the sweet spot for the no-pain barrier even in people like myself. If somehow all of this could just be pushed up the tiniest bit it would be so much better. People with old CRT monitors can remember the smooth benefits of going from 60Hz to even just 75Hz. Just overall nicer, more pleasant experience. If we pushed the standard up to 100 or 120 or even just 85, I think people would suddenly feel more comfortable and not even realize why.
