Re: New 2408wfp Power Save Mode problem..
I just order one Latitude E4300, Windows XP Pro, Mobile Intel Graphics Media Accelerator 4500MHD and two 2408WFP. One monitor has this issue and the other don't. I think this should be a monitor hardware issue. Change DVI cable will not solve the problem. Just get the replacement and will post result when I have it tested out.
I did my testing on four 2408WFP monitor with 2 laptop ( DELL latitude E4300 and E5500, both has Mobile Intel Graphics Media Accelerator 4500MHD). The laptop is connect thought a DELL E-port docking ststion. Out of those four monitors, only one has this problem.
Get it exchanged, before it is too late!
