I have a notebook asus S550CB with sk video 740m and a mediabox to watch TV on the LAN. I installed Ubuntu 16.04.1 mate and the video driver nvidia recommended.
Reflected a worse quality of the reproduced video with VLC than Win10 and Debian Mate, particularly HD quality. Do you have suggestions for solving the problem?
Thank you.
Hi Labbing, welcome to our forums 
How about posting you full system specs? Open a terminal and enter:
inxi -bThe bad performance may be do to compiling options . There is a tutorial in the forum to get vlc with full video accel . See this post [Tutorial] - Build (or download) VLC with hardware acceleration video decoding [OPENMAX-IL]

It all looks good. I would say you have selected the proper graphic driver. You card has been supported since version 340.
Has the VLC tutorial helped any?.
