Hey guys just got my new gtx 570 and I cant set the display to 120hz without it being blurry.
im using a dual link dvi cable and a 120hz lgw2363d monitor.
What am I doing wrong please?
I have tried both ports, installed latest drivers, installed monitor drivers
and tried without all these drivers installed aswell
Thanks all

Have you tried a different Cable?, Also Card could be defective....
March 8, 2012 12:30:37 PM

I thought that at first but alot of people seem to have the same issue

It will work. There may have been a run of bad cards or bad cables out there.

Does your old card run at 120Hz with that same cable?
March 8, 2012 12:39:39 PM

I had an amd before.
to get that to output at 120hz I needed hdmi 1.4a or displayport
my monitor has neither.
The card is running completely fine
it can be set to 120hz, the screen is just blurry thats all (in 2d mode)
March 8, 2012 1:09:53 PM

ok for some reason, when I set it to 120hz, I go into the monitors menu properties
and it says that it has set the resolution to 960x1080.
This is not what I have set on the desktop or nvidia control panel.
This is really starting to frustrate me now

The lower res setting stretched across your higher res screen would explain the blurry image.

Set the resolution in Windows to 1920x1080 and 120Hz. Does that do the trick? Then go back into control panel and see if the settings there changed according to your new setting.

Also, a dvi-d dual link cable is all you need for 120Hz and resolutions up to 2560x1600.
March 8, 2012 9:24:34 PM

that is with the resolution set at 1920x1080 in nvidia control panel and 120hz.
I thought this was just going to be as easy as plugging it in and done.
hmm...

AMD cards can do 120hz with DL-DVI. What they can't do is use HD3D with DL-DVI.

I know that now, I have a gtx 570 now and I want to know why I cant get this working in 120hz
March 11, 2012 1:50:40 AM

I still cant figure out why when I set the desktop to 120hz at full hd, the monitors settings pick it up as 120hz at 960x1080 and the screen is blurred, really really hope someone can help with this

Either try a different DL-DVI cable, or test your older AMD card with the same cable and see if it works.

Clearly the card doesn't believe it can send full 1080p information at 120hz due to bandwidth issues.

Have you tried changing your screen's picture mode? Because on my screen (24" Samsung P2450) if you change the what is called ''magicbright'', it can make the screen more clearer under different sort of graphic settings.

Cheers
March 13, 2012 1:49:21 PM

how would I change the screens picture mode?
March 13, 2012 1:50:19 PM

bystander what would the bandwidth issues be? this cable works fine as far as I can tell and the card should definitely output at 120hz

120hz blured, i'm almost sure you are not using DUAL LINK cable, if you are, try another DVI slot in the video card sometimes only one of them supports DUal LINK;
March 13, 2012 6:06:01 PM

Hey, its definitely dual link, and I have tried both slots of the graphics card and get the same results either way.

March 13, 2012 6:30:26 PM

well, if you can try with another video card would be good, but i doubt that is the problem, maybe if you mess around with screen settings (deactivate some options) you may find something that is now allowing 120hz to be displayed properly.

But i would re-check the cable:
http://www.datapro.net/images/1142.jpg
if it have all the central pins, it is dual link, otherwise it is not.
March 13, 2012 6:40:27 PM

it does have all the centre pins.
I tried setting it to 120hz using hdmi 1.4 aswell
and whenever I select it, it sets to 120hz
but then when I go back into the options it says
that it is only 60hz.
That definitely is the cable I have though

hdmi 1.4 supports 120hz only at 720p if i'm not mistaken it adds support to 3D 720p 60hz or 1080p 24hz.

i would try another DUal Link DVI cable...

It sounds like you have ruled out the cable, but you still haven't ruled out the card, as you still haven't tried it on your older AMD card. If it works on the other card, it's your video card giving issue

If that doesn't work, you should try the dual-link DVI cable on someone elses system. If works, then your windows install is likely a problem, and if it didn't work, then it's likely the monitor.
March 13, 2012 8:27:46 PM

I dont have the amd card anymore.
That card did go blurry at 120hz but that was because I had
a single link dvi cable at the time.
I have just ordered a new card to replace this one.
I am hoping that this is not something to do with the monitor.
LG said that the monitor cannot work at 120hz in the desktop
as it is not designed to work at 120hz.
I have tried playing games in 120hz like deus ex human revolution
and it seems to work well, but as stated the desktop is still blurry etc

That is strange to have a monitor that will game at 120hz, but not work at 120hz at the desktop. I'd think if it could do one, it can do the other. Perhaps it's not meant to be 120hz at 1080p?
March 13, 2012 8:37:18 PM

that was what I thought but that is AMD cards that cant do that. Nvidia cards can do 120hz at 1080p, just to double check though I tried running it in 720p and I found exactly the same issue happened

Again, this isn't true. I have run my 120hz monitor on my 6950's and 470's. They both can do 1080p @ 120hz with DL-DVI-D.

EDIT: one note, after reading your other thread where you tried to get Nvidia 3D Vision working. AMD cannot use HD3D through DVI or DL-DVI. AMD requires HDMI 1.4a (for 720p HD3D at 60hz per eye) or Displayport for 1080p.

normally televisions do that, they don't support 120hz, but they can reproduce that... but if i'm not mistaken that LG screen supports 120hz real display.

what television do is Post Processing Frequency, the frequency is not real, it justs increase the number of frames this causes a big delay on the image, the response time goes way high doing that, but since television are for movies, no problems there.

when you connect a computer to a 3D Television this post process is not possible anymore, and you will be running at normal 1080p 24hz or 720p 60hz...

Both Nvidia and AMD can do 120hz, i am also using a Benq 120hz display here with my nvidia 560ti.

amd card can do that too sometimes it is only one DVI dual link slot, but they do.

really not sure what is happening there can be the cable, the gpu may be with problems, or even the screen may not be really 120hz...
March 15, 2012 11:33:24 AM

So I am now on my 3rd video card and it is still doing it.
I now have a gtx 580 and it is still blurry @120hz on desktop
and I still cant get the 3d working properly.
When I try and set it up, I get to the point asking me to close each eye
and I see the same image in each eye.
I can adjust the depth using the glasses but nothing happens

It's probably not the cards, it more likely the monitor, or cable.

You also said it was blurry? Are you using HDMI or DL-DVI?
March 15, 2012 10:38:04 PM

dvi-d I believe its called
I tried hdmi aswell but to no avail.
I had the monitor working in 120hz before with my old card
I may try uninstalling the drivers again.

DVI-D won't work, it needs to be dual-link DVI-D.
HDMI won't work at 1080p or with Nvidia. HDMI 1.4a does work with AMD, but only up to 720p and only for HD3D.

Did you ever get a chance to try it on another computer? If you'd tried multiple cards, I'm sure we can rule that out, and it sounds like you've tried multiple cables, that leaves the monitor or windows install as possible issues.

Try the DVI port on the motherboard using the Integrated graphics. And you're absolutely sure the DVI cable picture you linked to has the exact same amount of pins your DVI cable has? On both ends btw.

It's unlikely it would ever have the same exact amount of pins as the connector, as most monitors with DL-DVI ports, use DVI-I which allow for both DVI-A or DVI-D connections (the DVI-D doesn't have the 4 extra pins around the horizontal shaped pin). Both dual link types have all 24 pins to the side of the horizontal pin, with no break, unlike the non dual link cables.

Take a look at this to see what you should have. You should have the 4rd one down: http://en.wikipedia.org/wiki/Digital_Visual_Interface
March 16, 2012 10:14:13 AM

the 3rd 1 down is dvi i single link?!?!?!
I definitely have the dvi-d dual link
I dont have a second monitor hooked up
but it does show 2 monitors when I go into
the display settings and no matter what I do
it seems to always recognize as having 2 monitors
March 16, 2012 10:16:13 AM

I meant the third 1 is dvi-d single link

120hz may not work with your cable or satellite feeds, but it'll work perfectly find for computer stuff, including gaming. Your TV's broadcast at a different hz than ours, but that won't effect normal PC use.

March 18, 2012 10:06:55 PM

http://www.nvidia.co.uk/docs/IO/115522/image4.jpg
is that the cable that I need?
I really hope I have figured this out.
I have the 24 pin + 1
Do I need the 24 pin + 5 with the 4 pins surrounding the 1 that would be by itself on a normal dvi cable.
http://www.datapro.net/images/1148.jpg like this one, if the link above didnt work.
Or should it just work with the standard 24 + 1?
I really hope that this is the solution because I am out of ideas

You do not need the one with the 4 extra pins surrounding the minus pin. Those are used for analog connections, and your monitor couldn't possibly use analog if it's 120hz. Your 2nd link is correct.

The only thing you have not tested is the monitor itself. You could try it on a friends comp, but it sounds like the monitor is not functioning properly, or requires you to change a setting on the monitor itself.
March 18, 2012 10:40:47 PM

damn, I really hoped I had nailed it then.
I have finally managed to set up the 3d glasses but
the monitor itself does not seem to be outputting 3d.
I can enable or disable 3d mode using the glasses.
I can alter the depth of field, but still no 3d.
Im getting a different set of glasses to try and see if
that makes a difference. But I really don't think it will.
If it comes down to it I may just sell this on, or try and
book it in with LG for testing.
April 22, 2012 12:17:59 PM

I've been reading this thread, and I couldn't leave you hanging for an answer.
I know why you're getting a blury image.

I should start by saying Hertz means cycles per second. In reference to monitors 120Hz monitors show 120 images per second.

I've been researching 3D monitors, and according to the specs for all LG monitors on the Australian website, no LG monitors do "true" 120Hz. What that means is LG monitors only display 60Hz in 2D mode.
If your graphics card is outputing 120 frames per second, and your monitor is set to 60 frames per second, then you'll get a blurry image.


How LG calculates 120Hz.
Because LG monitors use active shutter 3D glasses, they show one frame in the left eye for one 120th of 1 second while the shutter for the right eye is closed for the same one 120th of 1 second (120Hz). This means in one second, each eye alternately sees 60 image frames and 60 black frames. (This is also the reason 3D often looks so dark.)
The way LG is calculating 120Hz is by adding up the frames for each eye: 2 x 60 frames equals 120 frames (120Hz)."True" 120Hz monitors can show 2D images at 120 fps (120Hz).

For some reason, LG, and most other manufacturers' "3D" monitors don't have the option to show 2D at 120Hz. That's why I'm not going to buy an LG monitor. -I've got an LG TV though. ;-)
Personally I'm finding my search very frustrating because I'm after a true 120Hz monitor that also shows photo-quality still images, because I do a lot of digital photography. It also needs vesa mounting holes etc.

I do not know about LG monitors, but you are wrong about at least other brands. All the other brands, that I'm aware of, support 120hz at the desktop through DL-DVI. Mine included. Monitors that do 3D through HDMI are different, as HDMI doesn't support 120hz except through frame packing, which only works in 3D.

EDIT: I looked up his monitor on Newegg, and those who have used it are getting 120hz: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
