Samsung NP-RF711-S07UK laptop DVD play back very poor.

Hi, I have the Samsung NP-RF711-S07UK laptop with the Nvidia GT 540M graphics card. My screen res is 1600x900.
The problem I have is playing a DVD bought from AMAZ......... the quality on full screen is so poor [grainy] but if I shrink the screen the quality is brilliant
Is this a fault?
I believe this laptop is still of a high spec to play the standard DVD.
Any help would be fantastic.

 

DVD is much lower resolution than your 1600x900 screen. Most US DVDs (NTFS) are 720x480, and depending on how well it was transferred by the studio, some look absolutely terribly on HD displays, while others look OK. Even DVDs of the most excellent transfer quality will not look as good as HD content. (LOTR Extended Edition DVDs were always my reference for excellent transfers back in the days of DVD -- and the LOTR heydays )

Any laptop from the last several years should have enough power to play DVDs.

Which player software do you use?

 

Windows media player. I have downloaded this concert and it played brilliant. But due to reinstalling windows I lost the download.

 

Sounds like it is just a poor quality DVD (not the physical disc, but how the movie was scanned, transferred and encoded). That concert video you downloaded was a higher quality encoding and looked great. Again, no DVD will look as good as HD material (BluRay, downloaded, Netflix etc).
