    Hi all,

    I have just setup a new and working HTPC with MediaPortal to playback sat tv (DVBS2), MKVs and Blu Ray discs.
    I am going direct from my PC over HDMI to my TV.

    All is working fine - but the output quality I am getting on my TV is quite pixelated and grainy, and with some washed out colours.

    I have tried (and tried):

    tweaking the LAV codec settings - changing deinterlacing and hardware accelerator settings
    Purchasing the CoreAVC Pro codec (same thing)
    Purchasing a dedicated GPU (Radeon HD 7770) instead of my on board Intel 4600 Graphics (not much better)

    I am looking for an expert to help tweak my settings to get it as good as it can get - happy to pay someone for their time.

    Anyone?

    Just in case my specs aren't easily visible below:
    My System
    HARDWARE
    CASE: Lian Li V351 (Black) Case
    PSU: ATRIX Expert AX-550EXB ATX PSU - 550 W
    MOTHERBOARD: GIGABYTE GA-B85M-HD3
    CPU: 4th Generation Intel® Core™ i5 4570 3.20GHz Socket LGA1150
    RAM: 4GB (2x2GB) DDR3 PC3-10666C9 1333MHz
    GPU: MSI AMD Radeon HD 7770 1GB GDDR5
    TUNER: TBS6985 DVB-S2 Quad Tuner PCIe Card
    HDD1 (OS): OCZ 60GB Agility 3 SSD Solid State Drive
    HDD2 (DATA): Hitachi Deskstar 7K4000 4TB 64MB Cache Hard Drive
    BLU-RAY: LiteOn IHOS104
    TV: Samsung LE40D503 40" LCD TV

    Thanks!

    Please post some screenshots where we can see what kind of poor picture quality do you have.
    And please one more screenshot with activated video stats (Shift + 1)

    don't see poor picture quality there... especially on HD channels.
    Hat is wrong there? ok, picture on SD channels isn't so sharp as on HD channels, but i don't think you can get it much better scaled to your 40 inch LCD.
    maybe it looks worse on your TV and looks good on screenshots because of some weird settings on your TV?

    Hi,

    Maybe it doesnt come across well in the pictures.

    The video has a lot of "grain" and other artifacts.

    I think both my graphics card and TV settings need some tweaking.

    Found the solution on a forum.
    With Samsung LCDs you have to change the input (e.g. HDMI 1) type to "PC".

    It then handles the signal differently.

    Picture is crystal clear now.

    Stupid Samsung.

    Thanks for your help.

    I know the blu-ray is crisp because of the quality of the source. The problem is that I don't see any quality issue when listening TV on my laptop. The laptop is 1366x768 so I can't really compare with my 2048x1152, but I still feel there is something going on on my PC. I think the ATI video scaler filter does help. I will have...

    Im fairly sure all freeview HD channels broadcast HC-AAC, not MPEG 2 or Dolby Digital audio so you must be using something else unless ffmpeg supports HC-AAC now. ffdshow doesnt or at least I can't choose it in MediaPortal config if it does. Whats your LATM AAC audio decoder set to under TV Codecs?

    Shouldn't the list of rates include one with a frame rate of 30 and a refresh rate of 60? Is that not the basis for 1080i ATSC broadcasts?
