Wireless Display - Performance and Reliability Problems with WiDi
Performance and Reliability Problems with WiDi
Two month ago I received my new Laptop Dell Inspiron 15R (N5110) with Intel Core i5 Sandy Bridge, WiFi Centrino N1030, Intel HD Graphics, Windows 7 Home Premium 64 Bits and my new D-Link DHD-131 MainStage TV Adapter.
I had successfully made the setup of my WiDi with a LG 47" TV, and I have tested the WiDi a little without any problem, using the Clone Display option and the Extended Display Option (1920x1080). The WiDi interface have successfully updated the D-Link firmware and I have used it a few days without any problem. WiDi was performing 100% OK. Two days ago, I have decided to use it again, and for my surprise the WiDi now has serious performance and reliability problems, and it is totally unusable!.
The WiDi starts OK, but it have very poor performance, interrupting the video transmission after less than a few minutes, keeps turning the TV screen black and restarting again, sometimes shutdown the connection permanently. Other times there is a visible lag between the image in laptop and the image in the TV or sometimes the TV screen shows little coloured squares pixels and this causes the restart of the connection again and again. The problem occurs using the Clone display option and using the Extended display as well, appears that the problems is the same. All this is making WiDi totally unusable.
I have tested the WiDi connection using another TV (Samsung 32"), have reset the D-Link firmware to factory default, restored my Windows 7 to a previous restore point down to one week ago, installed new Laptop BIOS, reinstalled the WiDi application, but nothing resolved the problem.
As my Windows 7 Laptop is kept update by Microsoft (Windows Update) and I usually keep the hardware drivers updated using the Dell Support Center Tool, I suspect that some of updates for drivers or related software is causing the actual problem. A complete Dell hardware test showed no problems with the Laptop hardware.
Versions of the related WiDi drivers and software:
Windows 7 Home Premium:
Intel Centrino WiFi N1030: 14.2.0.10
Intel HD Graphics: 8.15.10.2361
Intel PROSet Wireless WiFi: 14.2.0.10
Intel WiDi: 2.1.42.0
D-Link DHD-131 MainStage TV Adapter:
Firmware: 2.0.39.0 (original) and 2.1.16.0 (updated)
Note: the blue screen logo on MainStage shows "WiDi 2009-2010" whereas in Windows 7 WiDi software it shows "WiDi 2010-2011". This is normal? What is the latest firmware level for DHD-131? If it is not 2.1.16.0 how to get it? Thanks

Problem Solved! Incredible! As I was concerned that there are some conflicts in the WiDi software, I have created a fresh new User ("WiDi") in my Laptop, and I do not believed when the WiDi worked OK! I have connect to NetFlix and watched about 1 hr of movie without problem! But my std user still do not work with Widi giving the same problem, I do not know why. Maybe some configurations stored in the User files? Anyway, I am considering now using my new user "WiDi" exclusively for use with Intel D-Link WiDi and NetFlix.

New Activity:
1)WiDi Related software:
Intel Centrino WiFi N1030: 14.2.0.10
Intel HD Graphics: 8.15.10.2361
Intel PROSet Wireless WiFi: 14.2.0.10
Intel WiDi: 2.1.42.0
2)The D-Link TV Adapter connects OK to TV. The PC WiDi connects OK with the D-Link TV Adapter initially. The real problem is that there is a bad overall performance and reliability in this connection .
3)Just have uninstalled WiDi V 2.1.42.0 and re-installed the Intel HD Graphics Driver from Dell site (V 8.15.10.2361) and re-installed the old version Intel WiDi Conection Manager V2.1.41.0 A02 from Dell site. The problem now seems worse: it disconnect in less than 15 seconds and keeps reconecting and disconneting many times, turning the TV screen black until, after about 10 times in this game, it disconnect permanently.
4)The WiDi application asked to download and install a new version V 2.1.42.0, I have accepted, it installed normally, but the problem remains.
5)Run Dell Tests for Intel HD Graphics and Intel Centrino 100% OK.
6)Run Intel Tests for PROSet Wireless and the results and reports shows it is 100% OK
7)WiDi Related software:
Intel Centrino WiFi N1030: 14.2.0.10
Intel HD Graphics: 8.15.10.2361
Intel PROSet Wireless WiFi: 14.2.0.10
Intel WiDi: 2.1.42.0

Status Update:
1) Problem is not solved. WiDi connection is broken and restarted several times in less than 1 minute until WiDi is disconnected permanently.
2) MyWiFi configuration uses default channel 1, there are about 7 others WiFi Nets near my home using 11b/11g/11n. My DSL Router uses channel 11 and WPA/PSK and WiFi works OK. Should I change the channel in the configuration of Intel MyWiFi to other than 1?

Found that all this problems was caused by the use of any non Standard Microsoft Aero Theme that probaly have changed the Video configuration. When I changed to a standard Microsoft AERO Theme the problem is solved.

sea_poh,
To use WiDi, you need to install My WiFi Technology. Try the instructions at...

Works on Windows 7 systems or later.

I had a similar problem after installing Adobe premiere pro. My casting quality got awful, sub 480p quality on the TV when it should be 4k uhd. I tried everything, update drivers, uninstall/reinstall software etc... The fix ended up being settings>display settings>scroll down to "custom scaling" >click it and a pop up says "log out and disable custom scaling", clicked that, laptop signed me out, signed back in and reconnected a WiFi cast and PROBLEM SOLVED!!!!... This issue had me going nuts for weeks. I literally tried everything and finally got my screen cast quality to 4k like it used to be. Hope this helps someone out there!
