Dual 27" U2711 and Nvidia 9800GTX

[jlfirehawk]

Will this card a 9800GTX+ run both of these IPS monitors at their native resolutions which is 2560x1440. I am running on a 26 and 24 inch monitors now but have these new Dells coming today and didnt think about this part until now. This way I know if I need to upgrade asap in order to run these or whether I can wait and see what new cards come out in the coming months.

This is the exact card I have http://www.newegg.com/Product/Product.aspx?Item=N82E16814130376

Yes, a 9800GTX can drive that resolution. The performance on newer 3D games won't be that great though, but that's to be expected.

Well I got it all hooked up but at this resolution the text with windows 7 looks like garbage I have never seen this issue before but it is next to unreadable. I even increased the dpi to 100 and it made a little difference. Anyone have a clue what could cause the text to be really distorted but any icons etc are fine.

ClearType?

 

[jlfirehawk]

Cleartype is turned on, the only way I can make them readable is turn the dpi up and it still looks like crap but I can at least read them.

OK I changed the resolution down to 1920x1200 and you can read everything and the fonts look normal again. I then went up to 1920x1440 and the fonts start to go goofy again but not as bad as when I was on 2560x1440. Anyone have an idea of what could be going wrong?

That is strange considering I have an 8800 GTS and it drives two 3007WFP-HC's fine (2560x1600)

I am assuming you are using the cables that came with the monitors right and not old cables?

I think higher than 1920x1200 and you need dual link DVI-D cables (which should come with the U2711 monitor)

also make sure the refresh rate is set to 60 hz

if you are using the old cables from your 24 and 26" monitors if their res wasn't higher than 1920x1200 chances are they are single link cables

MCHammer I owe you, color me stupid but in my excitement to hook them up I just used the cables that I had already running through my desk not thinking for once that the new ones would be dual link vs single link, I set my resolution back and changed the cables powered up and viola everything looks awesome now. I cannot believe I didnt even think of that at all. Much props to you mchammer. I was wondering why when I looked at the display info through the menu it would say 1280x1440 which I thought was odd, which now it reads correctly.

After a google search this was the only place I found someone with the same problem as me.
Only difference is I'm using a Radeon HD3200 IGP with the dual link cable that came with the monitor. Same problem; I configured it to 2560x1440 but the screen is garbled and the monitor believes it's being fed 1280x1440.

The graphics card should be sufficient to drive this, so what could be the problem ?

Does it work at 1920x1080?

Does it work at 1920x1080?

It works up to 1920x1200.
I´m starting to suspect that the ATI 780G chipset doesn´t have dual-link DVI...
