E series dock and display port issues?

Anyone else experience issues with the display port on the e series dock?

I've got a E6400, E4300 and E4200 that I'm using with a E Port replicator.
I'm connecting it to a dell ultrasharp U2410 monitor via display port.

Several times a day, the monitor will go blank and say there is no signal, then 10 seconds later turn back on.

Several more times a day the monitor will go into standby and say there is no signal, the only way to get it back on is to open up the laptop and press FN F8 several times to switch the outputs, and sometimes that will work, other times it won't. in that case I have to either reboot the computer, or go into the intel graphics settings, tell it to use single monitor, and use the dell digital u2410.

I've called dell support, they are useless. I've updated the video drivers, I've reloaded the computer, I've tried 3 computers (but on the same dock since I only have one docking station).

Has anyone else experience this issue? thanks

 

Do you have another monitor available to test with?

 

Does the same thing happen if you hook the monitor straight up to one of the systems?

 

I have an E4300 and a dock and a 2407WFP monitor and I had problems when using the DVI connection. When the monitor would go to sleep I would have to open the lid and fuss with it and sometimes the display would start "sparkling" all over. I went through countless hours of tech support and replacing docking stations and they were never able to figure it out. So I just switched to VGA and haven't had problems. It's frustrating and annoying that I have to do that but now I don't have those issues any more.

 

I tested it with a Samsung LCD using DVI interface.

Since it happens on three different E series, all with integrated graphics, I'm wondering if its a design issue.

Kind of like the issue with corrupt graphics if you have two different sized memory modules installed.

 

Hi,
my wife got a DELL E4300 from her work and complains about exact the same problem. When using it with the docking station and an DVI-monitor at her office, after a couple of minutes it will display "no signal" on the screen while(!!!) it is actually still showing the Windows XP desktop. After some more minutes, the whole things blacks out for about 30 seconds and then returns to normal until it repeats again and again...

She told me that once she managed to remove this behaviour by doing something to the system setting in windows, but she could not remember anymore what she did back then .

Anyway this problem returned as soon as she took her notebook back home and plugged in an VGA-monitor. Once she was back in the office and working via the docking station...

I could not find anything regarding this issue in any german forum. As her clinic has some kind of service contract with DELL, I will have her call in their service tecnician to see after this problem.

So maybe I can tell something helpfull later on.

Best Regards

 

I've saw this problem with my M4400, driving two Dell P2310H monitors... One of the monitors would lose signal briefly and then come back... Very annoying... Switching to DVI from DisplayPort resolved the problem.

 

Hi Again,

my wife got tired of this and switched for another monitor that would connect via VGA instead of DVI. That solved the problem for her. So it is definetly a DVI related issue.

No real solution, but maybe closing in on the problem.

Regards

 

well I've tried Display port and DVI, both have same issue.

Can't use VGA, the text is too fuzzy using VGA on a 24" monitor at 1920x1200 resolution.

I hope there is a solution soon, this is driving me nuts.

 

I had a similar problem. Connecting a M4400 via displayport cable directly to a U2311H. (not thru e-port though). I was using the latest drivers from Dell (188.40 A09) and it would not register a signal resulting the monitor going into Powersave. Wierd thing was that Windows 7 would still recognize the monitor as present and on.

In the end, I just downloaded the latest drivers via Nvidia's site (197.16 WHQL) and the system works fine now.
