Quality too low with Flash Player 32

Hello.

I have different pc in my home, and all those uses the leatest version of Flash Player. But on my notebook (wich was bought 2 years ago) the flash contents are showed with low quality than the other my Pc's. I tried to uninstall and re install the program, I try to use different browsers, I try to disable the hw acceleration, but the problem still here, and I don't know how to resolve it. How can I resolve this issue? Thanks a lot!
