Intel Communities: Message List - TV screen is blank

I'm having same problem. It was working before I had friends over, whenever they left I tried to connect to the TV. It said it was connected but the TV screen was black. I found that if I switch to extended display it works fine.

I was using a Belkin Screencast adapter I assumed the problem was with the Screencast adapter so I purchased a Netgear Push2TV adapter. It behaves exactly the same.

I deleted the WiDi software, made certain all drivers etc. are up to date and re-installed the WiDi software. Same behavior. Again, it works fine on extended display.

It works fine if I connect to the TV using wired connection (VGA and sound cable)

Paul_P,

Thank you for your help. I did try dropping the resolution, but wasn't certain which resolution was necessary. At first, when everything was working, my laptop resolution would automatically change as soon as it connected. It no longer does that. I tried all of the resolutions available, but always got only the black screen. I did make the resolution change after it was connected though.

Of the 4 secondary display options, I tried 3 of them:

Disconnect (I tried this - blank screen, as expected)

Duplicate (I tried this - still blank screen, not expected)

Extend (I tried this - still blank screen, not expected)

Projector only (I didn't try this - was afraid I wouldn't be able to get back to normal)

I have not tried connecting the laptop physically to the TV.

I talked with Sony support - spent over an hour with them. They uninstalled, re-installed, restored original version (using a sony app) of things, but could not get it to work. Eventually my support person gave up, and said I would need to talk to more advanced support. I have not yet called them.

So then I did a system restore. I restored my system to the date before I ran the update. It is now working again!! But, I fear that as soon as those updates are again installed, it will again stop working. Now that it is working, is there anything I can do that might help diagnose the problem?

Adam,

Thanks for the reply. Have you tried dropping the resolution on your laptop? Also have you tried using the extended display feature in Windows 7? After you connect the laptop to the TV it will show up as a secondary display and instead of duplicating the image you can extend the desktop to the second display. You would then be able to leave the laptop display set to the max resolution and drop the resolution on the secondary display (TV). Also have you tried connecting the laptop to the TV physically to see if the same thing happens?

The reason I ask is that the issue you are having sounds similar to connecting a laptop to a projector that does not support higher resolutions. Because you are getting audio it would seem that you are successfully connecting, but the TV is unable to display the image that is being sent to it.

Thanks,

Paul

I had previously installed all of the updates available at sony. I have now installed the updates at the link you posted in the order on that page - with the exception of step 2. The notes state that the generic driver can not be used on systems with ATI graphics. My laptop laptop has AMD Radeon HD 6630M hybrid graphics with Intel Wireless Display technology.

After following those steps, I get the same behavior: both my TV and laptop say it is connected, but my TV is just a black screen. I do get audio though.

What else should I try?

Adam,

Sorry to hear you are having issues. From the sound of it you may have tried part of what I am going to suggest already. I would recommend that you Download the latest drivers and software for all of the Intel® products involved. Here is a link to the download page, http://www.intel.com/support/wireless/wtech/iwd/sb/CS-031109.htm.

You will see that each step is lined out for you in the order that your computer will need to be updated. I would recommend following those steps to see if your issues is resolved. If you could please, run through those steps and let me know if that worked for you.

I am suggesting this because I have seen instances in the past where once one product is updated there are issues with the others because of installation order.

Thanks and I hope this helps,

Paul

TV screen is blank

I have a Sony VPPC190X. It came with WiDi installed. I bought a NetGear PVT2000. Everything was working mostly as expected (I would sometimes have to reenter the security code).

Recently, Sony updater installed some updates. After that, my WiDi stopped working. When I tried to connect, it would say connecting on my computer, it would say connecting on the TV, then the computer would give an error Unable to send desktop to remote display. Try re-installing intel wireless display.

I have downloaded and installed the latest Intel wireless display (2.1.41.0) and video driver - both from Sony. After that, when I connected the first time, I got a message that there was newer firmware available. I clicked ok to update the firmware. Now when I connect, I get audio, but the TV screen is just black. My computer screen still shows stuff though.

Previously, when it worked, as soon as it connected, my laptop resolution would change (from 1920x1080 to something smaller). Now when I connect, my resolution does not change.

Please help!!!
