    Hi Everyone,

    So I am in the process of putting together a parts list for a new HTPC. The goal is to make a future proof HTPC which can do the following:

    • 4k @ 60Hz (HDMI 2.0 needed)
    • HDCP 2.2 compatible (netflix 4k streaming)
    • HDR
    • Onboard graphics
    • Quiet
    • mITX form factor (small)
    • Budget $500-600
    • Ideally play UHD Blu-rays from an optical drive

    None of the current intel CPUs (except Gemini Lake) handle HDMI 2.0 from the onboard graphics so I decided to return to my old roots and build and AMD system. Most of the Intel boards convert the DP to HDMI 2.0 via an LSPCON chip which has given many people headaches. The Ryzen 2400G seems to be the ideal candidate for an HTPC with the built in Vega 11 GPU. The Ryzen 2400G supports HDMI 2.0 on most of the current motherboards so that is a huge plus. The one major drawback from the AMD cpu is that it seems the DRM for UHD Blu-ray playback only works with the Kaby Lake Intel CPUs, I will probably pass on this requirement.

    Here is what I have come up with:

    CPU: AMD - Ryzen 5 2400G 3.6GHz Quad-Core Processor ($159.99 @ Newegg)
    Motherboard: ASRock - B450 GAMING-ITX/AC Mini ITX AM4 Motherboard ($123.98 @ Newegg)
    Memory: G.Skill - Ripjaws V Series 8GB (2 x 4GB) DDR4-3200 Memory ($100.98 @ Newegg)
    Storage: Samsung - 970 Evo 250GB M.2-2280 Solid State Drive ($99.88 @ Newegg)
    Case: Fractal Design - Core 500 Mini ITX Desktop Case ($60.84 @ Newegg)
    Power Supply: SeaSonic - FOCUS Plus Gold 650W 80+ Gold Certified Fully-Modular ATX Power Supply ($69.99 @ Newegg)
    Optical Drive: LG - WH14NS40 Blu-Ray/DVD/CD Writer ($60.98 @ Newegg)
    Total: $676.64

    In this build I have dropped UHD blu-ray and just put a regular Blu-ray drive. The PSU may be overkill but I am a big Seasonic fan, I may drop it down to a 550W.

    My questions:

    1. Will this build support HDCP 2.2? Does Ryzen 2400G support it now?
    2. Is it true that you need Kaby Lake for UHD?
    3. Do you have any other suggestions?

    Thanks for any feedback!

    So, I'm not going to answer most of this, I'm just gonna speak to one particular topic: HDR support

    HDR support on PC is balls. For PC use, you probably want 4K@60Hz@4:4:4 chroma subsampling. In order to get the HDR though, you have to drop to 4:2:2 or lower chroma, and toggle the switch in Windows for HDR mode on Win10. Unfortunately, this is a manual button-press and not something your media playback software can press for you on an as-needed basis, and playing back SDR content when in HDR mode is less ideal thanks to the chroma subsampling and shitty weird behaviors by Windows in general.

    If you just want to play back media, seriously, just buy a Shield. I say this as someone who owns a HTPC. If you aren't going to couch surf the internet a lot, or play games a lot, then a standard thick HTPC isn't really needed anymore and a Shield will handle all the media playback you like. For optical playback, well, you're on your own for that, but it's likely a small percentage of your use so maybe just buy a standalone BD player the day that problem comes.

    Yup. Because this is true:

    I don't know why it's true, but I can confirm it. This is why I haven't been very excited about HDR on the desktop and an HTPC is unfortunately no different. I really don't know why it's still a bit of a mess but it is.

    All while my Shield works great.
