I just got my Lenovo Thinkpad 120E with AMD HD Radeon 6310 card. I am able to play youtube videos of 1080p resolution and video files of full HD / Bluray resolutions if I play through VLC or one of those std video players.
But playing 1080p contents in browser (other than youtube) is flickering. Even netflix HD contents are flickering and A/V sync goes off.
Network Bandwidth seems to be fine since I am able to play those contents in same browser (Chrome) in my HP elite (NVIDIA)
Since downloaded videos files are playing fine, I think my device is capable for handling HD videos. Then why browser play is not working.
Please help me to identify the issue. I dont want to return the laptop just for this problem.
Let me know if you need more info on the card to give suggestions.
Thanks in Advance,

Hey there jeykumar83,
To clarify what your dealing with so that the community can better assist, what operating system are you currently running? Do you experience this in other browsers as well, Internet Explorer or Firefox? Currently, what is the AMD Catalyst™ Software version and driver version for your video card? And to confirm, you are using the x120e?
EDIT: If you will see if when playing netflix in 720p, do you experience the screen flicker as well?

If you will verify if you have Microsoft's Silverlight installed. Thanks jeykuma83.

Thanks for the response. Here are the details you requested.
OS: Windows 7 64 bit
AMD Catalyst Version using: 13.1
Yes. I having the same experience with IE and Firefox as well.
Of course i have microsoft silverlight working and I am using lenovo thinkpad x120e.
Not sure whether netflix is streaming @ 720p when the issue is seen. But it always happens when "HD" icon in the netflix webplayer turns on. Other than netflix I also see the problem while playing you tube videos of bluray quality. But as I said in my previous post. If I download those videos locally to my machine and play using VLC or WMP classic, it plays fine.

Hey there jeykumar83,
I'm seeing that Netflix HD streams at 720p and youtube HD seems to display 720p/1080p. Does the flicker occur in a standard viewing setting or fullscreen?
Additionally, has this been going on for awhile, or is a recent problem, perhaps starting around a driver update? I found on a previous forum from quite a while back the following:
The performance for streaming Netflix HD is rather lacking. However there are some measures you can take to improve the performance while the compatibility issues involving Silverlight are worked out. The below was copied/pasted from the Lenovo Support forum regarding this exact issue:
1) Download Silverlight 5 (beta)
2) Download 11.8 AMD driver (or whichever is latest at the moment)
3) Verify Silverlight playback here: http://www.iis.net/media/experien...aming1080p
if streaming Netflix in HD is not a priority for you, there is a setting in your Netflix Account to lower the streaming quality. Choose the middle or lower option and you will not get choppy streaming performance
Now I was unable to find the Lenovo Forums thread that this person had mentioned, but it does give mention to a compatibility issue affecting Netflix HD. Considering I found this from a post from over a year ago, I am uncertain on if it is relevant to your situation and how it would be relevant to the youtube side of this issue.
I will continue researching in the meantime to see what I can dig up. Thanks jeykumar83.

I checked with the silverlight demo app link. It plays fine. But it starts with 2050kbps and goes back to 350kbps in few mins. But my HP elite stays at more than 3000kbps all the time in the same network. What I am suppose to conclude from this experiment? My silverlight is already of version 5.
One more thing which you might want to know is that when this problem happens, Norton pops up saying that my browser is using too much of CPU and my task manager shows my chrome is contributing about 80% of total CPU load.
My processor is AMD E-350 1.60 Ghz.

Seems its the CPU. My HP Elite (i7) shows only 22% CPU is in use. With AMD its 100%
Is AMD E 350 1.60 GHz such a low end processor? Any possiblity for tuning / optimizing? Help please.

Slightly newer ATI Mobility Catalyst drivers (v12.10) can be found at:
Perhaps installing these will make a difference, but to answer your question, yes, the AMD E-350 CPU is for netbooks and other small-form-factor, low-power devices. Performance-wise, it competes with Intel's Atom and i3 processors.
