Poor video playback, display quality

Unluckily purchased Toshiba satellite S50T-A494, and returned due to dead pixel, got a 2nd piece which has some left mouse button problem as it touches with the boundary and give noise.

Apart from that the video quality is worse, overall picture is little snowy and contrast is low. I put side by side my 4 years dell and the dell has high contrast. Then I played an HD video and the video is not at all looking an HD, contrast is very less, this also i noticed pronouncly by playing same video on old dell laptop with same vlc media player.

Regret to buy it and it is I7 with 8 GB ram, Nvidia Geforce 2GB Vram GT-740M but Intel HD graphics as 2nd adopter? May be this intel is the culprit which I didnt know before purchase.

Is there a way to improve the video and display quality or at least use Nvidia for everything?

It comes with pre-installed Windows-8.1 and the display fonts in Internet explorer and the images are less sharp. Not sure why I wasted money on it.
This is what i am getting with a 1100 USD laptop, frustrating.

 

Hey Tractable, i'm sorry that you are going through this. I had a similar experience with video playback and quality.
I went to the Toshiba website and entered my model # then downloaded the latest video drivers. Afterwards, videos played flawlessly.
I think you should try that.

 

Thanks Mezzi,
I have returned it and got a new Dell with similar specs, no problem with the dell like i mentioned for toshiba.
