ATI + LCD @ 120hz causes jittering/distortion problem

[Conditioned]

Doublepost. Oops

In fact it turns out it is not true 120hz like you stated. It is 60hz for each frame, basically for each eyeball to generate 3d.

Url?

So what does 60Hz per eye, per second equal? Assuming you're not a cyclops.

Ok, I will tell you. You get a monitor that is capable of delivering 60Hz per eye, at the same time, although in an alternate frame method for shutter glasses.. Which means 120hz.

How does that equal 120?

120 = 120hz

60hz one frame and 60hz another alternating frame does not equal 120. This is not rocket science folks...

Yeah, and it's doing all of it in 1 second. Not 60Hz for the first second and 60Hz for the second.

1 Hz = 1 cycle per second. What do you get when you have a monitor that can deliver 2 separate images at 60Hz each in 1 second?

I think you need to imagine this. The twisted crystals in a TN LCD has to be able to move at a certain rate (or redraw). When you have an alternating image on screen, such as when running 3Dvision, all the crystals have to redraw for every frame. From one alternating image (left) to the other (right). And it has to be able to do it 120 times per second (effectively 60 times per second per image).

And we are quite aware that this isn't rocket science. In some ways, I'm sure LCD technology is even more advanced than building a solid rocket booster. But who knows.

So is this:

60 or 120Hz!?!?

Umm you are confused with the HZ. It goes for a frame not second. That is why 24 FPS is best to watch a movie in.

Uh, they're talking about games, not movies. 3D gaming is 60 frames per second per eye, i.e. 120Hz. In one second the monitor will display 60 frames for the left eye and 60 frames for the right eye, which is 120 frames in one second. The shutter glasses block one eye when a frame for the other eye is displayed.

Hz is definitely per second. 1Hz is one cycle per second, in this case one vertical refresh cycle per second. LCDs are almost always run at 60Hz but games or movies may not display 60 new frames per second. In that case some refresh cycles don't change the image on the screen. In movies, when refresh cycles are not aligned with new frames you get 'judder', which is why 120Hz is such a big deal on TVs even if they can't actually take a 120Hz input.

The 3D Stereoscopic Experience

The 2233RZ, in conjunction with NVIDIA’s advanced software, automatically converts over 350 games to stereoscopic 3D without the need for special game patches. High-tech active shutter glasses, designed with top-of-the-line optics, deliver double the resolution per eye and ultra-wide viewing angles than passive glasses. In addition, the new pure 120Hz LCD monitors unlock crystal-clear, flicker-free stereoscopic 3D gaming that provides 60Hz per eye.

This is taking the thread the wrong way guys.

Bottom line is this. It's 120hz without the 3D glasses that works with vidia software.

It might be 60hz with the glasses, I don't know and I don't care. It's not some weak solution or interpolated image. It's true 120hz. You can read it in every single review out there and see it explained in the youtube reviews.

Eh? 3D vision displays all run at a genuine 120 Hz.

That means they can accept and output 120 discrete frames per second. That’s why 3D vision works on them, because the glasses block alternating images to each eye, so each eye only sees half the frames the display shows (60).

But the actual display runs at 120 Hz, and the glasses have nothing to do with that.

I've found a working fix for it now! \o/ Long story short..

Download rivatuner
http://downloads.guru3d.com/downloadget.php?id=163&file=4&evp=2d213e528fb556c354432a3976bff55a


Open Rivatuner. Click on the right triangle icon located beside the card information. Mine says something like: "256-bit RV770...". Next click on the first icon that looks like a card. Check the check box for 'Enable low-level...'. Also check the 'Apply overclocking at Windows startup". After I overclocked by 25mhz, it was all gone. It might work with less but right now I'm just glad it works click Apply and you should be all set.

EDIT: I realize I wrote this as a solution, but I have just tried in vain with powerstrip, afterburner, ATI overdrive and rivatuner before to get it working.

Hmm, good point. How can it be classified as dual 60hz chips? I thought true 120hz had to be a single 120hz chip?

They aren’t dual 60 Hz chips because the display runs at 120 Hz. Forget about the glasses; they don’t change what the monitor is doing. Glasses just change what the eyes see.

Think of these displays as a CRT running at 120 Hz.

 

[Conditioned]

ps. Just to clearify my issue. I cant set 100-120hz in 2d at all. In 3d, I cant set the option (nor force it by overriding edid or using one of the tools like rivatuner/refreslock etc) unless I totally reinstall the driver and then only until next reboot.

 

[Mawphoise]

Sorry to insist, but this works with linking two monitors at the same time? without any disadvantage? im going to buy the 2233RZ tomorrow and i have a HD 5870..i think its worth the risk

its still not fixed right? ;\ btw when u say "native" resolution it means, you can only get 120 Hz in the game using the 1680*1050 resolution IN the game as well? or just 1680*1050 on the desktop and any resolution in the game itself? (sorry for the noobness)

 

[Conditioned]

From what I read yes, but its not officially supported and you probably have to spend time getting it to work.

 

[Mawphoise]

plug and play LOL only installed drivers from the cd...feels so bright so nice man...xDD it works apparently how can i be sure im using 120 HZ btw? (it says on the ATI thingy that its at 120 HZ, but how can i be sure?)

 

[tihifnis]

Through the OSD

 

[Mawphoise]

im a noob, define OSD ahah xD and wat is it, and possible link <3

 

[tweakboy]

ATI driver issues, thats all this is.

i have ATI and dont have a problem so far

 

[BTRY B 529th FA BN]

10.1 drivers are suppose to fix this issue - i seen it in a list of fixes on the AMD forums

 

[tweakboy]

ATIhell with their horrible drivers! Return the card and get nvidia and your problem is gone. Stick with the big red and your gonna have this problem along with other problems as well... gl

Interesting thread. I have a jittering issue in Company of Heroes. The lines jitter up and down one line. It is so annoying I cant play the game anymore. I have 2x24" Samsung LCDs.
I have a 4850.
