W510 Win7 X64 - 2nd external display wont start

Another W510 "bug" x2

 

I have W510 and 3 series plus dock - with 2 external screens attached but:

 

1. After using internal screen, putting W510 to sleep and docking it - 

a. only screen 1 will turn on. I cant even force screen 2 on

b. Screen 1 only starts in 1920x1080 resolution and not 1920x1200 native resolution

 

This happens every time. Im using latest Lenovo driver: 8.16.11.8955

 

Problem 2:

If power management shuts of displays - primary display comes back fine upon "activation" but 2nd screen comes back in "zoom" mode. (looks like everything is blown up to 4-6 times the size) - forcing me to enter display settings and change resolution to something else on 2nd display - and then just let it revert back to original settings.

 

Anyone got a clue on how to fix the above?

I would not be at all surprised if these were bugs as I suspect this configuration doesn't receive much testing from Lenovo.... If I were you, my first step would be to try the latest drivers directly from NVidia's website and see if they help. Be sure to make a restore point though, so you can flip back easily to the 8955 drivers if you're not comfortable (or if it doesn't help).

the latest drivers from NVIDIA is even worse.

 

waking from sleep they alternate switching on and of screen 1 and 2 for about 60-120 seconds  - and plenty for "graphics driver failed" in win7 - both on my W700 and the W510. I have already rolled back to 8955...

 

incredible they have so big quality problems in NVIDIA that they cant even make stable drivers again.
