Just bought a new Dell Inspiron 2320, it has integrated and dedicated video card. Under display adapters i see "Intel(R) HD Graphics Family" and "NVIDIA Geforce GT 525M", if i disable Intel driver, the Nvidia driver doesnt work. I need Nvidia to be responsible for my desktop display, as i cant calibrate colors properly with a crappy Intel HD controls. The colors look horrible and over saturated... i need it to be better for work. Thanks.
I just read the reviews from customers for that PC on Dell's own website. Other people have complained about similar problems. Some even said that it was the worst Dell PC they'd ever owned. It sounds like the problems are endless with that one. As for your specific problem, I've seen similar things done with other PCs back in the old days of AGP graphics ports (before PCIe came out). Some companies would make the integrated graphics chip use the 3D acceleration of the AGP port exclusively, not allowing an add-on card to use it. So, when someone would try to upgrade their graphics, they would not have any 3D acceleration in games. Something similar may be happening with your PC. It may be best to contact Dell or a community of Dell customers to find someone who specifically knows about your problem. Otherwise, returnign it may be a good idea.
Your notebook powered by NVIDIA-Intel proprietary technology called Optimus - http://www.nvidia.com/object/optimus_technology.html . In this tech NVIDIA GPU have no video outputs, using instead a special buffer in Intel integrated adapter memory to push picture for displaying it via Intel video outputs. So, if you disabled Intel drivers, you will get nothing from NVIDIA GPU.
