videos are zoomed way out when plugged in, but play fine when on battery power

Not sure if this is the right discussion forum for my problem. If not feel free to move it. I am fairly new to posting.


Just recently I have been having problems viewing YouTube, Hulu and videos on other websites with either Firefox or IE, videos all appear zoomed way in, but the videos play fine using Chrome.

Plus when trying to play wmv or avi through Windows Media Player the videos all appear to zoomed way in just like on-line videos where you can not view them too, but if I load the videos into another media player they work fine.

I have the latest version of flash installed on all browsers, have uninstalled them and reinstalled them thinking maybe this was the
problem, but still having problems.

Noticed sometimes the videos work fine and other times have problems with the videos being zoomed way out.

Here's a screenshot of how videos look when plugged into ac


Just found out why the problem is off & on. If I unplug the ac adapter and run battery power all videos play fine, but if watching a video and I plug ac in videos will zoom way out to where you can't make out what is on the screen
Why Google Chrome is not affected either way, who knows.

I have no idea how to correct this problem.
If any one has any suggestions I would really appreciate the help

Thank you in advance,

Maybe try go into Catalyst Control Center and reset all settings - assuming your graphics card is AMD/ATi.

 

Thank you for your suggestion. I do have a AMD/ATI card. Been working with HP on this to and so far they have had me update video drivers(mine were the same version) update the bios, reinstall HP Power Manager.
And I have no idea why, but they had me reset IE 9
They did inform me that my problem was 1 of 2 things:
1. A software problem
2. A hardware problem

Once again thank you for taking the time to reply.
Your help is very much appreciated

An update of something I discovered
An update. If I log on as a different user all videos play fine.
I really don't want to have to get everything else working under a new user if I don't have too. Unless there is an easy way to do it without to much hassle.

Seems to be just affecting Firefox IE9 and Windows Media Player.
Open for ideas on what to look for since under new user solves problem

Thank you

 

problem partially solved.
Decided to go ahead and create a new user Account which solved the problem with viewing videos in Firefox & IE 9, but still was having trouble with viewing videos in Windows Media Player 12. So decided to give Media Player Codec Pack 4.2.2.817 a try and now I can view all videos with no trouble other then wmv and mpg formats in WMP 12.

Since I do not use WMP that much if any and all videos play fine in UMplayer I am going to consider problem solved, but if anyone comes across this message and has ideas as to why the video problem only existed when plugged into ac adapter I am really curious.

This problem I think even stumped HP and at times I got the feeling that they did not believe I was having this problem.

To all who have replied and viewed my message I want to thank you though.

Later,
Mark
