Hello,
i have a brandnew YOGA 910 with an Intel HD Graphics 620 and the following problem (tested with 5 Displays, 3 HDMI, 1 DP, 1 DVI Adapter).
On the external Monitor I have a very good picture as long as I use "Clone" for the Multi-Display-Mode.
If I switch to "Extend" as I want to use both monitors the picture becomes bad. Which means on Powerpoint and Word the picture is much worse than before, when using a tool like "Enterprise Architect" you cannot work anymore as you cannot see which icons you are using.
With my current MAC AIR everything works fine (even with no name adapters).
Has somebody an idea?
I have updated all drivers from the Levovo homepage to the latest version.
Best Regards and Thanks in Advance
Ritchie

Ritchie1962: Thank you very much for joining the Intel® Graphics communities. We are sorry to hear that the multiple display configuration is not working properly.
In order to try to fix this problem, please test the laptop with the "extended" mode feature using the same resolution that you used on "Clone" mode.
Which Windows version are you using?
Could you please provide a picture in order to see how the displays look like?
On the link below you will find the latest graphics drivers for the Intel® HD graphics 620 controller, it is version 4729 for Windows® 10:

Ritchie1962: Thank you very much for providing that information and those pictures.
In this case then we can try to install the drivers manually:

Hi Alberto,
i gave back the notebook and will buy a MAC, thats the easy solution, because:
- on a MAC with retina display it works perfectly also with an external monitor
- We have tested this on another Lenovo 910 and the same problem occured.
- It seems to be a design problem (my assumption is that when the HD620 needs to drive a 4k display it cannot drive also an external monitor with a useful resoluton)
( by the way, also using a lower resolution on the main display did not help).
- I do not have time to try to "repair" a problem that is created by Lenovo and Intel.
- I have already spent 20 hours on this problem and when I multiply this with my daily rate the cheapest solution at the beginning would be to throw the notebook into the thrashcan (because i wasted much more money with my search for a solution as I paid for the notebook).
Best Regards and Thanks for your support
