  1. Did you get a chance to test/try performance of Intel Wireless Display *WiDi* on 15z?

  2. For streaming wireless display, I need to have a TV with supported feature (or buy an adapter). So I'm not able to test it.

  3. Thanks for the benchmark. I just bought the same XPS 15z but for the windows experience index, under "Intel HD Graphics family" I got a score of only 5.9. Does that mean my graphics card is not running to its full capability? Is there a way to make it do so?

  4. You're welcome. Sorry to hear about that. I think it is the because of the new driver shipped with your system.(Mine is v 8.17.12.6639) Same thing happened to me when I updated the graphics card driver. I'm not sure windows experience index is a good benchmark though. Try a 3D mark test and compare the performance with other laptops (available online).
