8.1 Alpha Win 10 Limits CPU Max Frequency
Installed 8.1 alpha on Monday. Significant improvement over 8.0 (which I had only installed Friday after W10 upgrade, to excellent timing, thanks ). Install went well, if a little slow. Overall seems to be ok, May have had the odd window pop up at the wrong resolution - dragging it to 2nd window a back again sorted that.
But..... My usual mode of working is to use 2 x displays over Display Link, and turn off internal display (ie 2nd screen only mode). I soon as I go to this mode, the cpu maximum frequency, as shown by resource manager, sticks at 31%. Turning off 2nd display (but still using displaylink for network, keyboard, mouse and audio) and the max frequency returns to normal behaviour. I have tried 2nd display when not using displaylink, and behaviour is normal. As you can imagine, at times this makes the system very sluggish. There are times when I have to resort to working on the internal display. System is Surface Pro 3 i5, W10 Enterprise version 1607. Toshiba Dynadock U3. 1 x HDMI monitor, 1 x DVI monitor. |

Hello Lloyd,
Thank you for trying and the feedback. To solve the issue of the computer crawling to a halt when the embedded display is off, please make sure you have installed the September cumulative patch from Microsoft. It is KB3194496. Kind regards, Alban

Thanks for the reply. I hadn't realised that my update process was broken - patches now installed and cpu limit has gone.
I have had a couple of instances where one of the two external displays has shown random noise making it unusable. Is this a problem you are aware of? |

Thanks for confirming.
I haven't heard about this noise yet. Would you please be able to capture it through the Print Screen snapshot and a photo of the monitors showing the defect? The way it looks can tell us where this can come from. Kind regards, Alban

Hi Alban
I haven't forgotten your request, but I've not had corruption since your post. Maybe the windows updates have solved it. If I do, I'll try and remember to grab a shot. Lloyd |

Not had one of these for a while. Here you go. (Now using the latest version of the driver - 8.1M0).
