WiDi Latency Issue [View all]

Okay, I have Windows 8 and after a couple of hours downloading the necessary drivers and software for my already installed WiDi, I finally got it to connect to my HD TV to use as a second monitor.

Now, there's about a 4-5 second lag between actions on my laptop and what appears on my TV.

The reason I had to download all of the drivers and other software from Intel was because there is apparently a problem with Windows 8 and HD TVs.

I've been told to revert to Windows 7 drivers, but I'm afraid that will just make it not work again. I can live with the latency, but I don't want to lose a couple of hours work for nothing!

So, I'm just throwing it out there in case someone else had the same issue and has a different solution.

The specs on my laptop are (sorry about the copy/paste; at work and can't remember all of them):

Includes Inspiron 17R Special Edition i17Rse-3589BK notebook
2.4GHz Intel Core i7-3630QM quad-core processor with 6MB cache

8GB DDR3 1600MHz memory
1TB 5400 RPM hard drive
2GB NVIDIA GeForce GT 650M graphics with Optimus technology


Specs on the HD TV (sorry about the copy/paste):

Do a full backup before you revert to the old drivers and you won't lose your work Fumesucker Aug 2013 #2
Thanks! I hadn't even considered that. Fantastic Anarchist Aug 2013 #3
Go into the Nvidia control panel (it should be in the system tray) Gore1FL Aug 2013 #4
What does that do? Isn't Ivy Bridge my i7 processor? Fantastic Anarchist Aug 2013 #5
Ivy bridge provides video processing, but if you have an nVidia card, its GPU is better. Gore1FL Aug 2013 #6
Thanks for the information. Fantastic Anarchist Aug 2013 #7
Well, it worked at first ... Fantastic Anarchist Aug 2013 #8
