Bug ID: 395759
Summary: Monitor Displays refresh rate changes when connecting
an HDMI cable.
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
The laptop is an HP envy x360. For this laptop if I set the refresh rate to be
59.93Hz I can't notice any flickering, but for 60.01Hz or 40.01Hz I can notice
flickering.
On startup the refresh rate is set to "auto", but I don't notice any
flickering. Then when I connect an HDMI cable to extend my display to a second
monitor I can notice flickering. When I look at the refresh rate, it's set to
Auto. So I set it to 59.93 and the flickering goes away. (This doesn't affect
the extended monitor in any way).
If I disconnect (or also reconnect) the HDMI cable, the refresh rate is changed
to auto and I can see flickering.
