Hello,
Soon I bought a T520 refurbished laptop. I can say it is a new one. The battery count was on 3 cycles. I use it mainly for 3D modeling with SWks. Software is set to run with the external graphics NVS4200m. Today for the first time I turned it on an external monitor and noticed that the Software background window does look very well. Principally it is with shadows that are overflowing. It is not noticeable on the 15'' full HD screen, but on the big screen seem jagged and without smooth transitions. Furthermore, some of the built-in complex backgrounds doesn't show. When I start the program with the integrated Intel HD3000 graphics the complex backgrounds are showing. Basically NVS4200m is slightly better than HD3000, but the most important features for 3D processing are much better. I wonder why the integrated graphics is doing better than external. Moreover I don't think it's normal look. I installed the latest driver from Nvidia. I also tried with an old one, downloaded from Lenovo support, but the result is the same.
Here are the features of the graphics:

NVS4200m vs Intel HD3000
DirectX 12.0(11.0) vs 10.1
Shader Model 4.1 vs 4.1
Open GL 4.5 vs 3.0
