Dual Monitor Setup But Only 1 Adjuster

[kutaycinar]

Switched to using dual GM27-FQ ARGB monitors but only one is detected and the adjuster works.

They are both connected via DisplayPort directly to an RTX 2080.

Restarting the app seems to sometimes switch which monitor's brightness is affected where the slider starts to control the other monitor's brightness.

Other times the app fails to detect both monitors as controllable.

This error persists even though both monitors have DDC/CI are enabled.

However, resetting the NVDIA graphics driver with CTRL+WIN+SHIFT+B seems to resolve this error message but then still only one monitor is controllable at a time and the original bug persists.

Power cycling the monitors seem to have fixed my issue.

Thanks for reporting.
According to the log, these monitors fail to report their capabilities via DDC/CI.
In such case, you can use /preclear option. See #270 (comment)
