120hz

[dacca]

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....

 

[dacca]

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

 

[ubercake]

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?

 

[dacca]

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)

 

[dacca]

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.

 

[dacca]

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.

 

[dacca]

I know that now, I have a gtx 570 now and I want to know why I cant get this working in 120hz

 

[dacca]

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

 

[bystander]

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

 

[dacca]

how would I change the screens picture mode?

 

[dacca]

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;

 

[dacca]

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

 

[ricardois]

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:

if it have all the central pins, it is dual link, otherwise it is not.

 

[dacca]

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...

 

[dacca]

I will buy another one, but I dont want to keep buying cables as I have already bought several ones that havent worked

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.

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?

 

[dacca]

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
