Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

WARNING: Windows Mixed Reality PC desktop Graphics card upgrade can overload the Power supply

This is not relevant to laptops. :D:D

When thinking about upgrading for example a two year old NVidia graphics card this probably generated about 60 watts and needs a 250 watt power supply just for itself.

Therefore the PC case manufactures put a 500 Watt power supply in the case. The extreme gaming PC cases, Microsoft calls Windows Mixed Reality Ultra PC, have 850 to 1000 watt power supply.

Now if my graphics card is from NVidia GT750TB which requires loading 118 Watt then a 250 watt power unit is ok for driving the current machine and the original case has a 500 watt power supply.

Now lets look at that shiny new ASUS NVidia 1060 and calculate the new value which is now loading value of 340 watts requiring a 526 watt power supply.

When you install the ASUS NVidia 1060 will still work because many budget PSU don't have overload protection!, damaging motherboard, CPU and memory.

This means that you are left needing at least a 850 watt power supply. if you have one with overload protection that's £179!, the same price as the graphics card.

All the upgrades need to be installed preferably by a custom PC builder as there is mains power 240/110 volts involved, so add £40 to fit this.

Many people forget that ASUS NVidia 1060 require two slots, the ASUS NVidia 1080 requires three slots!!

All these costs add up in some PC cases doubling the unexpected costs.
Summary
Asus NVidia 1060 is £251 + 850 watt power supply £120 + installation, two days unable to use, £60. Total at least £431
on top of the £890 of the original machine

Finally now you have a CPU bottleneck and need another 8GB memory for rendering.

My local custom PC builder can build a WMR/VR for £1241 and cheaper if parts are recycled from the original PC.

For business this is simply buy a new WMR Ultra PC. For the hobbyist these are unexpected costs, but for either group any damage is unacceptable

    Well... Thats why I bought the 1050 TI instead :#

    So did I! B)Asus Geforce GTX 1050 ROG STRIX Gaming 2GB GDDR5 Graphics Card

    This is driven directly by PSU so wont blow mother board only 75 watts!

    Just upgraded my PC to NVidia GT1050 graphics card.
    There were problems getting the screen working.
    1. On a new install/upgrade of NVidia GT1050 graphics card the HDMI display MUST be directly connected to HDMI 2.0 port initially.
    2. Connecting HDMI monitor to the Display Port via UHD 4K adapter results in a black screen!
    3. You must have Download and Run GeForce Experience before you start and the Internet network must be connected.
    4. When you install the new automatically downloaded drivers, you MUST use Custom Installation. In the Custom Installation tick the box in the bottom left "Perform clean install", if you don't some of the drivers don't get replaced from the old graphics card, or Windows Update.
    5. Once the drivers are loaded restart the PC.
    6. Now "hot swap" the HDMI monitor cable from the HDMI socket to the Display Port via UHD 4K adapter.
    7. Wait for about 17 seconds until the software is reconfigured then you should see the Desktop on the HDMI monitor
    8. Connect the HP WMR headset HDMI cable directly to the HDMI 2.0 port on the NVidia graphics card.
    9. Connect the USB 3.0 (blue Insert) cable to the USB 3.0 port
    10. If the is an error
    Whilst installing a new NVidia GT 1050 graphics card this error code 2181038087-5 showed up on the Mixed Reality (MR) Portal when connecting any WMR headset.

    WORKAROUND
    Pulled the USB 3.0 Headset cable from the Current socket and looked for USB 3.0 socket nearby with the blue insert.
    Pushed the USB 3.0 Headset plug in the socket, there was the new device detection bell/bong sound and the MR Portal immediately started to work.
    The really weird thing was found upgrading to NVidia GT 1050 graphics card after pulling the mains power cord from socket to put back on the right part of desk. Restart Windows 10 PC and MR Portal gives error code 2181038087-7
    Tried the same workaround as above and this worked again!.

  • Well I bought Asus Geforce GTX 1050 ROG STRIX Gaming 2GB GDDR5 Graphics Card
    When installed in the PC the BIOS startup test failed saying you must install the PCIe 3.0 x16 connection drawing power from a 6-pin external power connector
    and of course don't forget you have only 2 ports, one HDMI 2.0 and a single DisplayPort connection, which needs an adapter
