XPS M1530 and 2560x1440 on U2711 with HDMI [SOLVED AND WORKING]

Hello there,

I'm using XPS M1530 and U2711 and I had the same problem. I wanted my 2560x1440 throught HDMI.

After hours of testing and thinking I figured it out!

current resolution is higher than a maximum resolution... funny

HOW TO:

(I'm sorry for czech windows :D I hope you got the point)

1) check, if your videocard has a duallink output. If not, don't even try :-)

try to find it out here (http://www.notebookcheck.net/NVIDIA-GeForce-8600M-GT.3986.0.html)

2) use this version of NVidia driver and control panel (195.62)

download here: http://rapidshare.com/files/454110799/nvidia-195-62.zip

I was not able to make it work with newer ones...

3) use my tweaked driver (I've just added a 2560x1440 possibility to HDMI resolution list)

download here: http://rapidshare.com/files/454110938/U2711-tweak.zip

or just use some from windows (ie. flat panel with resolution 2560x1600)

how to install this driver?

a) open device manager

b) select driver tab, update driver and search driver in computer

c) select  "choose driver from list" option

d) choose from disk and browse to my tweaked driver

OR

uncheck the checkbox and select the windows standard one (flat digital panel 2560x1600 60Hz)

 

e) open the NVidia panel, select resolution tab, select your U2711 and click add new resoluion

f) allow showing resolutions not supported by monitor and click on create new resolution

g) here is my settings screenshot

h) try to change the resoluion to 2560x1440

j) HOPE IT WILL WORK ! :-)

4) there are still some problems with windows and nvidia driver... when I turn off computer with 2560x1440, windows force restarting graphics adapter and change the resolution back at starting up...

but you can change it to 2560x1440 back in nvidia panel
