Poor image quality?

I recently purchased a very expensive lenovo x220 and I noticed immediately when trying to play a hulu video that display quality is shit. I am very confused what could be the cause of this. It looks like there is some kind of low quality "noise reduction" filter being applied that's doing an utterly terrible job. I can watch the same hulu video on my 10 year old fujitsu notebook and it looks perfectly fine and normal. Please let me know if you have any idea what the culprit would be and if there is some way to disable it. I'm attach a screenshot

I like the fact that it says 360p right at the top of the pictures. Needs more 720p content.
 
Yes, the image has been upscaled, but look again...that is not the issue here. The larger image has been filtered with a discontinuity preserving smoothing algorithm that reduces high frequency content by flattening out regions of similar color and creates artificial edges where there should be gradients (similar to Photoshop's 'smart blur' that nobody uses for that reason). There are also artifacts created by some other means, most noticeable in the lower left white area of the wall, where you can see a jagged contour that is not present in the other version.

These differences are even more noticeable when watching the moving video. It's quite horrendous actually. I am wondering if the decoding is being done with some hardware acceleration that uses really crappy fast approximations. If so I am hoping somebody knows a way to disable it.
 
Maybe, do you have directx(9) installed? I had a problem before where I didn't install DirectX after reinstalling my laptop and all my video look like ass.
 
I don't use hulu so this might be off base, try right clicking on the video, if there's a flash menu or "settings" that leads to flash then there should be a hardware acceleration disable/enable checkbox, try changing that. If not, open up a youtube or other flash video and go to settings, and enable/disable hardware acceleration through that.
