I have been using my Latitude e6410 with a second external monitor for four years without any problem. This week, the display on the monitor turned fuzzy. I'm trying to diagnose and fix the problem.
First, I checked all the connections (cable and a/c power cord). Everything was correctly and firmly plugged in. Then, I connected the external monitor to a different computer, using the same cables, and it works perfectly. The display on my laptop itself is perfect.
This led me to conclude that the problem is with the e6410. I reinstalled the Intel graphics driver but that did not solve the problem. Now I am hoping for some suggestions from the community or a Dell expert who might be monitoring these discussions.
Does anyone have any idea of what I can try to get the nice clear display back again? Is it possible that something became unseated inside the chassis of the laptop, and what can I try to do to check that and fix it?
The operating system is Windows 7 Professional 64-bit.
Many thanks for any assistance or advice.
