I have HP ProBook 4431s laptop upgraded to windows 8.1 having intel core i7 2620m & according to intel this processor is WIDI compatible as shown in http://ark.intel.com/m/products/52231/Intel-Core-i7-2620M-Processor-4M-Cache-up-to-3_40-GHz#@product/specifications… but when i run WIDI compatibility check it shows failure saying that your processor is not compatible.
I also tried driver update utility and updated all drivers but no luck, please help
