Hello,
I have problems with WiDi on my notebook Lenovo Y50-70 together with Full HD TV Panasonic Viera TX-42AS750E (other devices like Mobile phone Moto X or another notebook with Windows 7 64 bit work perfectly)
Problem description:
I can find my TV via charms menu, then add TV as projector (notebook and TV communicate), at the end TV is added into devices list, picture appears on TV for cca 0,5 second but at the same moment TV says that mirrored device has been disconnected and that I should try it again. OK everytime I try it again system says that it is not possible to connect to the device. If I remove TV from devices list and repeat first time connection it ends in the same loop every time.
I have tried all solutions mentioned on these pages (no firewall, no antivirus, 2.4 GHz network, manual updating of video and WiFi drviers) and nothing worked for me even this trick with WiDi software in Windows 7 compatibility mode didnt work.
I have bought this TV/notebook combination with intnention to mirror NTB picture on TV without any problem, now I have expensive pair of devices which dont communicate as described.
My HW configuration:
TV Panasonic Viera TX-42AS750E with the latest firmware 3.072
Notebook Lenovo Y50-70
Processor Intel Core i5-4200H
Ram 8GB
Windows 8.1 Pro 64bit
WiFi Intel Dual Band AC-7260 AC - driver 17.1.0.19
Intel HD graphics 4600 - driver 10.18.10.3977
second graphics Nvidia Geforce GTX 860M - driver 9.18.13.4448
I am very disappointed with current status. Is there any solution? The only possitive thing is that I can see the picture from NTB on TV for 0,5 second.
MSinfo32 and Intel SIU files are attached.
