    Poor video quality; driver issue?

    I have been a Windows user all my life but got bored of it. Decided to give Ubuntu a go. Downloaded and installed Ubuntu 13.4 yesterday and so far am loving it. But one thing I've noticed is that graphics quality does not seem to be as good as it was for Windows 7 on the same laptop. (Lenovo Z580 with Intel HD 4000 integrated graphics card) The colors don't seem to "pop" and appear a bit washed out and text will give me a headache sometimes because it seems hard to read. But the main issue is video quality, I've downloaded VLC and have tried watching videos but the quality is very poor. The colors are all washed out and "bland" is the best way I can word it. Also if there's too much happening on screen the video becomes glitchy and choppy. It doesn't seem like the computer can handle it but before I could view HD movies in perfect quality. I was just wondering if this could be a graphics driver issue that could be fixed? I've tried searching the internet but the results seem confusing. Was hoping someone here could help me out.

    Do an update (use Update Manager) then have a look in Additional Drivers. Anything there for your graphics card?

    You could also open a terminal (Applications>Accessories>Terminal from memory) and paste this in:

    Code:
    lspci
    Hit return and post the output here. That will tell us what card you have in there and give a ton of info about your machine.

    It shouldn't really be a problem
    I can tell any difference on my Intel Lenovo or other machines. Though the drivers for Intel are not the same as in windows... don't ask, it a stupid and complicated story of licencing.
    I actually think the font rendering is better now in Linux than in Windows.

    You could post the result of this

    Code:
    lspci -nnk
    we will see most of your hardware and drivers from that. Please put it in code tags

    Re: Poor video quality; driver issue?

    Firstly, thank you both for replying.

    I did the update and went to Additional Drivers, it says that I have no proprietary in use and there's nothing there in the list. I've now tried various HD videos and youtube and I get the same issue, colors seem like they have low contrast and are not really vivid at all. If something fast happens the video gets choppy and a random thick black line will flash across the video.

    This looks normal

    Youtube
    I have read of some issues recently in youtube in other forums where there has been a need to disable HW acceleration in the flash settings

    Is the trouble only with HD
    And by HD what do you mean spec wise?

    No it's in VLC too not just youtube. By HD I mean 720p or 1080p MP4 files but it's not just those. Any video gets choppy and random lines and pixelation happens if something fast or sudden happens on screen.

    I don't really watch much video, but some from BBC is HD. It always seems OK though.

    So you installed the restricted extras? I guess.

    VLC should be fine, I don't use it myself as I prefer smplayer as it remembers where you left off.

    Not sure what else to suggest.

    This may be a stupid question, but are you running at native resolution?

    I am, yes. At least I'm using the one Ubuntu chose as default: 1366X768 (16:9). My only other options are 1360X768 or a 4:3 display.

    One thing does not mean the same as the other. Sounds like a realistic resolution, though. You might find that text becomes easier to read if you fiddle with the sub-pixel rendering settings.
