porjecteurs with a vga video, I opted for the option dvi vga adapter. the problem is that I had taken adapatateurs for Mac, its worked well at the start and suddenly, boom nothing, black screen.
I have a Dell phone, with the technical service, a imcompétence, ZERO, must say this is because on a PC a year and a half, I had to buy 900, scheduled for photo and video, view the price of this etai on foutage guele, he wanted nothing to do, plus it was a misuse of my part. I connected well on as usual, and then noir.et screen plus I had to pay 149 for reconfiguring software
Bastre the next day, the quality department reminds me, I ask nothing, and after she manipe, it is concluded that, adapters Apple release (yes because I took Kanaan), are not compatible, pourqoui and walked her at first, and suddenly, the mystery of IT.
Anyway, I bought this, by the advice of Dell's quality service and its progress nikel top.
So if you have the same problem, especially not apeller Dell's service because it is a very very big waste of time, but buying this adapter, and everything returns to normal
