andrewf@nvidia would you happen to have any updated info from the engineering team about this issue please? /biggrin.gif' class='bbc_emoticon' alt=':biggrin:' />

There are so many variables, we just about need the engineers to start making housecalls! I really wonder how many of these are things like the monitor being tilted a bit or sitting too high relative to the user's eyes.

PS. Although as I'm at working I cannot check this - but later I will check IF the ghosting is BOTH top and bottom...

Well, as I explained - IF you have some ghosting on top and bottom - but there is close to none in middle - glasses are in proper sync than... and fault lies in monitor.
Some issue might be if glasses are not working correctly too, but in that case you'd get more middle screen ghosting too.

AFAIK your monitor is one of 1st 120Hz ones, so yeah... new ones are a bit better, but they also do still suffer from some ghosting aswell.

i confirm that disabling usb 2.0 + disabling legacy usb support produces a change on the sync signal
unfortunately the change is not in the direction i need but in the opposite one, so my ghosting is increased :(
for anyone with ghosting i suggest giving it a try.

my mobo is an asus p5k

I have had the top and bottom ghosting problem and was able to fix it by upgrading the driver and/or changing from 120Hz to 110Hz or 100Hz.

Yeah, probably your monitor is fast enough for 100hz, but not for 120hz.

Same problem, top and bottom, yet slightly more at the top, which means that its basically in proper sync? This is with 3DTV Play, Sony 2010 model TV and x16. However, im using the Sony glasses which hook into the TV.

I just read most of this thread and i noticed a lot of people with 1 and 2 posts claiming to have fixed their problems with odd, simple fixes, which is suspicious. Are there any long timers with lots of post that have fixed their ghosting problems with something simple?

[font="Trebuchet MS"][font="Trebuchet MS"]Hi all,

I can confirm that I have been a able to workaround this issue. I had severe ghosting on the top of the screen on my AMD PHENOM II X4 system
Here are a few of the things that worked on the port adjacent to the one with the NVIDIA IR emitter:

1. Play a game, and plug in my IPOD for the first time on a new Windows 7 Install: The ghosting will go away for 10 secs as the system scans the IPOD
2. Play a game, alt-tab out, and plug a 4GB USB disk. Start copying a file and alt-tab back in the game: The ghosting will go away until the file is being copied.
3. Play a game with USB headphones: THERE's NO GHOSTING

I'm a programmer by profession, and all the above point to one thing: All computers have different latencies at the USB ports depending on what's plugged in and the system hardware specs. NVIDIA has to sync up the IR emitter taking these latencies into account[/font][/font]

Hi guys,

Kamran is 100% correct. I had this exact same issue also on a Phenom II system (890FX chipset). There's an issue with the latency of the USB controller that's causing the top-of the screen only blur.

All I had to do was plug my pyramid into one of my USB3.0 ports as they run off a different controller, problem fully resolved.

If you have this issue, pick-up a USB PCI (PCI-E) add-on board with its own controller for £10-£20 should resolve your issues. May as well grab a USB 3.0 board and take the opportunity to prepare yourself as more USB 3.0 devices pop up.

Cheers

I have managed to totally solve my ghosting issue. I too was plagued by the top ghosting at 100, 110 and 120Hz

I recently upgraded drivers to the 270.61 WHQL drivers on the nVidia website. As with quite a few others i was getting massive sync problems with this driver, it would start out with the normal ghosting at top at and then would slowly spread down screen until totally ghosted, then would do same over and over.

I have seen that the 275.27 Beta drivers have fixed this syncing issue. I installed the beta drivers and low and behold no more ghosting at the top at all for me! I have had a couple of very minor glitches but its a start. Cant wait for the fully released drivers :D

Also it seems to have fixed an issue I was seeing on my Viewsonic VX2268WM where I was getting alternating light and dark horizontal lines while in 120Hz mode.

Heres my specs if it helps:

AMD Phenom II 965
Asus M4A785TD-V EVO AMD 785G
4Gb G-Skill Ripjaws DDR3 PC3-12800
PNY Geforce 260 896Mb
Samsung SpinPoint F1 HD103UJ 1TB
Viewsonic VX2268WM

Hope this helps others!

I can confirm with the new driver, 175.33, fix my top of the screen ghosting issue!! YAY..... but now I have it at the bottom of the screen. DA' FU**?!?! >.<

Hello all,

I would like to say that it is almost 2 years and due to this community nvidia managed to finally do something about ghosting.
In my case the latest driver 275.33 dramatically reduces the ghosting. I can see only a little ghosting at the top of the screen but now I can say can play 3D how it meant to be :)
I have also disabled USB 2.0 and I get rid of entire ghosting on top but it accentuates on the mid of the screen maybe its due to the 2233RZ.
But I say it is a huge step forward.

Sorry to resurrect this thread, but what happens to the ghosting now? I have brought a PCIe 3.0 USB card but it doesn't solve the problem. I want to disable 3.0 and have it run at 1.1 but doesn't know how. Tried to plug different things to the adjacent port with no luck. Did not disable USB 2.0, instead I brought a new board with new CPU (ASUS p8p67 +2600K), no luck. I believe the solution offered by others work, it just that I am not doing it right.

What happens to the idea of manual latency/sync adjustment? I understand that ghosting should not have happened and manual adjustment should not be necessary, but it is necessary when the problem is open ended. For 2 years since purchase and gone through several video card upgrades and the same issue still haunts me. I am not given up, but am not quite sure what shall be done. Nvidia, help me please.

Am I the only one who is so dumb with ghosts where anyone else got theirs exorcised? H..E..L..P......Glosts is still haunting me, has been haunting me for the past 2 years and I still can't get use to it. Help!

the display is crappy/old gen
the new displays use better panels (stay away from CHI MEI) and they have firmware tricks where they set up the overdrive so that the ghosting across the entire screen is uniform (different overdrive values for different parts of screen)
