Hallo everyone
First of all, this will be a list of problems, which i think is all related.
Spec:
Laptop Lenovo ThinkPad T430s
Intel core i7 - 3520 2,9GHz
8 GB ram (2,73 avalibel)
32 bit Windows 7
Intel(R) HD Graphics 4000
NVIDIA NVS 5200M
My monitor:
Asus asus Vg278he
144Hz and 2ms (GTG) tracer-free
Connected to the laptop via Displayport -> HDMI cabel
Problem 1.
I have not been able to choose which grapich card i want to use. I have all drivers updated, and tried using windows sittings and Nvidia sittings to change this. No result.
Problem 2.
When i try to set the Hz via windows sittings, the only option i get it 60 hz - why is this?
Problem 3.
When i play games, my screen flicker. Somtimes it even freezes and i have to close the program to restart for another result.
problem 4.
My laptop is mainly for work and i will not be able to install another copy of windows higher that 32 bit. Is there anyway i can get more out of the RAM without doing so?
I hope someone have some advice for the best usage of the setup.
Thanks!
