I have a weird issue with a laptop. It has been this way since new (almost a year now).

HP Spectre 13” with all the bells and whistles.

I am using 4 USB -> DVI adapters to drive 4 monitors with the DisplayLink driver.

All 5 screens (4-27” monitors and the laptop screen) show what they are supposed to.

When I move the mouse over to the laptop screen the screen turns to black. I move mouse off screen and it returns to normal.

Here is the crazy part - if I restart windows it behaves normally! I can boot in the AM, login and do a quick reboot and everything is normal.

This has been consistent through Windows updates, DisplayLink updates, reinstalling drivers, etc.

Anyone encountered anything similar? It is more of an annoyance than anything else.

What graphics card?

Pretty sure USB interface can't handle 4x displays without goofy artifacts.

It doesn't surprise me.

Been using the same setup for many years. Several different laptops (Lenovo, dell, MacBook) for years. This is the only one to exhibit this behavior.

Laptop graphics card is intel iris. USB adapters are Diamond USB 3.

The thing that really stumps me is about how the blackout disappears after reboot - never to appear again until a long shutdown.

Graphics issues are hard to track down.

Have you updated all your driver's, etc?

Have you seen if changing refresh rates, screen scaling, or resolution change the behavior?

Maybe just reboot every day?

active display adapterz?

Done all the above - settled for the last option.  At least Win10 boots pretty quick!

Still wish I could figure out an alternate solution.

Yup
