V5-122P - ThunderBolt and USB 3.0 HDMI dongle

I purchased a V5-122P notebook just 4 days ago with the intention of replacing my 17" Sony Vaio with something a bit more portable. I use my Vaio mainly as a desktop machine, with the lid shut and 2 x 24" dual screen monitors plugged, one using the HDMI port and the other using a USB 3.0 HDMI dongle.

 

Since purchasing the V5-122P, I have updated to Windows 8.1 and started to migrate my files across, I purchased a thunderbolt connector and attempted to connect my screen.

 

Just using the thunderbolt connector and an HDMI lead into one of my monitors, I can set the resolution to 1920 x 1080 however the content on the monitor is "windowed" ie, it appears about 70% smaller than the screen itself.

 

The USB 3.0 HDMI cable, when plugged in appears in my device manager, the drivers are all running fine, however when I plug in the HDMI cable to connect to the other monitor, nothing happens.

 

The dongle is backwards compatible with USB 2.0, the same thing occurs, I can plug it in, the machine chirps and I can see it in my device manager.

 

All my drivers are up to date, in fact I have newer versions that what I was advised to get by the online chat earlier.

 

All my hardware is fine, I've been using and continue to use this setup on my Vaio.

 

Any suggestions would be gratefully received.

 

Thanks

 

Nick

    Try changing the screen resolution in the laptop (if the highest resolution is selected, decrease the resolution). Also check go the video controller settings (can be found in Control Panel) and change the Aspect Ratio.

    Hi,

     

    Thanks for the suggestion, regrettably, still no different.

     

    Cheers

    For anyone experiencing a similar problem, I have managed to get a full screen output now using the following thunderbolt adapter from Cable Matters - http://www.amazon.co.uk/gp/product/B00DRK2ZIK

     

    And I updated the Graphics Card Software to a beta release here:

     

    http://support.amd.com/en-us/kb-articles/Pages/latest-catalyst-windows-beta.aspx

     

    This gives you something called "AMD Catalyst Control Center" where you can adjust the Underscan / Overscan option, by default it was set to Underscan at 10% which is why the 2nd display was scaled down by 10%, I've no idea how I could have changed this setting using the standard Display Options. Setting this to 0% gave me a full screen on my second display and it's no longer blurry!

     

    Just got my other USB 3.0 HDMI dongle to sort and hopefully I'll be running dual external monitors.
