Intel HD graphics on Dell E6410 and E port dock

[MaxBurn]

What I have:
Dell E6410 laptop with i5 and intel graphics
E port docking station
Samsung TV LN32A550

Problem, when I try 1080p60 I get green lines very bad on display. Updated to latest dell driver no change.

If I select 1080 with refresh rate 30hz in the driver the picture looks good but my display actually says it is being sent 1080p60 interlaced, which looks like crap if you scroll or move anything.

Anyone know why I can't do 1080p60 on this computer? Previous Dell D630 with D docking station was fine, plus have a desktop that works fine with this monitor as well. There is a KVM switch involved, but these other computers work fine through the KVM.

You tried Dell's driver. Did you try Intel's most recent release?

I forgot to update. Yes intels driver is significantly newer and fixed some of the weird behavior in their quick select utility that i was having with the dell driver.

It did not fix the problem though. Unfortunately I found that with a cable straight to the monitor from the dock it works fine. I dont know why the two dont get along but it does work fine at 1080p@30 which i guess on a LCD for a work computer is good enough.
