Public bug reported:
Hi,
I have HP15 Gaming Pavilion bought 2-3 years ago.
I had Windows 10 before (not it is the second OS due to this bug [I can't use
Ubuntu with this bug]), and Win 10 has no problems.
No solution [that I found over the internet] worked.
I have to have at least two displays.
My connection technology:
PC HDMI output -> HDMI-VGA(+audio) transmitter -> LED 20' Display (external
monitor)
Win 10 have never had any problems with it (it has good drivers).
When I add any input to the second screen - it blinks and flickers so terrible
that I can see nothing - a white screen problem. If I do nothing - it will turn
to some picture in some time, but if I make any action at the second monitor -
flickering and the white screen problem appears again.
I think these are drivers. I tested the equipment in Win 10 after I found this
bug - and it works perfectly (so, the hardware is good).
It is a typical notebook and this bug is crucial. I use two monitors to type
codes and work on PC. I can't survive with just one monitor.
Right now when I am typing you this message the second monitor became white
again for quite a long time (I did nothing there).
I hope you will be able to fix this bug :)
Best wishes,

PS: When typing this message I found another bug compared to MS Windows.
When making screenshots (Alt/Shift + Print Screen) - it makes perfect picture
even when you actually have the second monitor white all the time (so the
screenshot is not how it is).
I made an actual photo (and deleted some parts of the background not related to
the monitors/computer). You can see a white screen, but the screenshot shows a
"perfect world" with a perfect picture which is not how it is on the screen.
Windows, on the contrary, makes actual screenshots. And Win 10 test of this
monitor never have this white screen or any other monitor problems.
Moreover, when the monitors stops to be white for a second it depicts different
picture (more terrible image; it is disproportional, with font heavily
readable, but the screenshot functions shows an "ideal world" a user can never
see :)
I made this detailed description to help Ubuntu. I think the project is
great in concept, but poor in realization. Such bugs make it impossible
for users to use Ubuntu (who can work on just one monitor? Who do not
wish to make screenshots with what he/she actually sees on the monitor
[rather than modified images with the pictures users do not actually
see]?).
