This is probably a very specific question. In both my previous Inspiron and current XPS, the line weights and text in my CAD program (DataCad) display are much heavier than they should be and don't seem to show thinner or thicker line weights as they should. I've compared the display to other laptops, looking at the same file in the same program, and also spoken extensively with the tech support folks for the CAD program.

I don't have any other CAD programs installed so I can't tell if it's some settings conflict with that particular program.

Working with their support, we've played with a lot of settings, both within the program and in Windows. Nothing has helped. They have not seen this before so their best guess is that it has something to do with Dell video drivers. That seems unlikely - though not impossible - given that it occurs in both Dell laptops, and their drivers are up to date. But it's sort of an Occam's Razer situation in that we can't find other explanations.

Anyone seen anything like this or have any suggestions?
