Is it just me or is 85hz not flicker free?

[Lasker]

Everyone seems to say 85hz is flicker free and that the human eye can't tell the difference between it and a higher refresh rate? I seem to be able to.. I just switched from 1024x768 @120 hz to 1600x1200 @88hz and I can tell a big difference. I can even notice a difference between 100 and 120 (Although it's much more slight)

Wouldnt it be a better comparison to keep the resolutio static when testing refresh rate. Try 85Hz at 1024x768, then try 120Hz at the same resolution.
Can you notice a difference?

Personally, I find as the resolution increases my eyes tend to become slightly more sensitive variances in the monitors refresh rate. At 640x480, I can't notice anything about 75Hz. If I increase the resolution to 1024x768, I can see the difference between 85Hz and 75Hz, but once it rises above 85Hz I can no lonnger distinguish any difference.
At 1600x1200 I can actually visually distinguish a slight difference between 85Hz and 100Hz... I've never seen more then 100Hz at 1600x1200, so I can't comment beyond that.

Same with me, when I got WinXP I run my desktop at 1280X1024 at 85Hz when it used to be 1024X768 at 100Hz, and I can see the difference. What is even worse is that I can really see what appears to be 60Hz in movie theaters or it is low framerates. I know TV operates at 24fps which is much lower than what I am used to in games.

I used to think 1600 by 1200 at 85Hz was good on my 19" monitor but after running 1600 by 1200 on this 15" notebook LCD, I can really see the flicker on the CRT, whereas the LCD looks crystal clear, rock solid, and every last pixel is razor sharp.

woah i thought it was only me. while i was watching black hawk down last week, i could really tell that the screen was flickering.

Personaly I don't notice anything in movies.

Guys, only a few small % of ppl in the world are sensitive enough to sense anything past 'true' 75Hz. I say true because a lot of ppl say they can tell 85, or 75, or 100.... that's a bunch of bull. In most cases, either their video card sucks, the monitor sucks, or the signal actually isn't at 85, or 100 due to misconfiguration. Turn out the lights and turn up the contrast on your monitor. Look to the side about 30- 45degrees. If you're peripheral vision can see flickering, then raise it until your peripheral vision doesn't notice it anymore. Don't look at the screen directly, the eyes are more sensitive to flickering when looking at something off-center.

If you can actually see flickering at 100... your vid card suks... or your monitor is cheap.... or you're superman.

You should look @ the rigs of some of the folks making comments before you make a broad, uninformed statement like that.

Ever played CS @ 120HZ... then @ 85HZ? Discernable difference.

I've got odd eyes. I'm one of those lucky people who honestly don't notice flicker even at 60Hz. Which is a good thing, because my apartment has power lines running right by the window, and anything other than 60Hz causes monitor jiggle. I can see it with my peripheral vision, but not straight on. Thank God I'm moving soon, and I can crank my monitor up to 1280x1024@85Hz. Just to reduce eyestrain.

Yeah, me too, I get annoyed watching tv or movies sometimes because of the choppy motion/flickering. Then again, it would require alot more bandwidth to have the same amount of channels with higher framerate/refreshrate.

Movie Theater>Film 24 FPS 48hz refresh rate
Broadcast Video(TV):NTSC 30FPS(29.97)>60hz refresh rate, PAL 25 FPS>50hz refresh rate.

This is NOT "bull" and it is NOT imagined, nor is it caused by bad hardware.

Windows XP is causing 75 Hz and even 85 Hz to flicker for some reason, where previous OSes did not.

I've had Win 98 and XP on this box, and still run 98 on my old box. In Windows 98 with the SAME hardware setup, 75Hz is flicker free. BUT, on Win XP with an identical hardware setup, even 85 Hz causes a bit of flicker. I cannot comfortably run at anything under 100 Hz.

Futhermore, this did not occur in 2K either.

When I loaded XP on my GF's mother's box, I found the same anomoly.

This has happened with a GF2 and a GF3 and a TNT. It has happened on a BX 1 and a BX 2 mobo, and an 850i mobo. It has happened on a PIII a PII and a P4. It has happened with XP's native drivers, the card manufacturer's drivers, and nVidia's latest reference drivers.

Oh, and for the guy trying to tell us it's crappy hardware, this has happened on a 24" Sony GDM-FW900, a 21" Dell Trinitron 1600HT series, and a 19" Samsung 950P. It's happened on a Hercules GF2 Pro, a Gainward GF3 Ti500 and a Stock Dell TNT.

Furthermore, it's been witnessed at two different addresses.

I think, with my testing, that we can safely say this is an XP bug, and not due to bad hardware, imagination, nor superhuman capibilities.

Ok, sorry, let me rephrase that:

If you can actually see flickering at 100... your vid card suks... your monitor is cheap.... the software is screwed up... or you're superman

My main point is that no one sees flickering when it's TRULY at 85 or 100. Very, very, very few notice 75.

 

[mrman3k]

I unfortunetly can see these flickers at 85Hz only when I look a little off of the monitor otherwise when I look head on I do not see it as much. Also my eyes notice a lot of things, at an eye exam the doctor said wow because I challenged them to give me very small text and I could read it from over 2X the distance where normal people with 20/20 stand. Also if you are used to watching 60Hz you will not notice the flicker, it is only when you get used to 100Hz and go down that you notice the difference.

Is it possible yuou are referring (whomever) to the XP refresh rate problems in XP? You might set you desktop to a certain refresh rate, but in games (and other programs I would imagine) it runs at 60. There is a program for an XP refresh rate fix for NVidia cards.

No, this occurs in 2d. I've loaded the 3D refresh rate fix, and that's all fine.

These, while they may be connected in some way, are two different problems.

Well Ok then

I think this needs to be addressed by MS. I'm obviously not the only one that has witnessed XP's refresh rate bug.

I am running dual boot with 98 and XP and I like XP better but find my self in 98 90% of the time because its easy on my eyes, there is a problem with XP and refresh rates, i dont know what it is but i can see flicker much more on XP.

Does anyone know where I can find this program? RTCW loads at 60Hz, and it is inconvenient to change it every time via the console.
