Causes the on-screen display control lock being accidentally enabled (a feature that disables the joystick to prevent accidental presses), the joystick stuck or unresponsive, a crashed OSD overlay that needs a power-cycle, a monitor firmware bug, and a conflict with AOC's G-Menu desktop software. Fixes in order: unlock the OSD by holding the joystick/Menu button, power-cycle to reset the overlay, clean the joystick switch, refresh the firmware, and close G-Menu.

Causes a loose or failed power cable / power supply, a dead or tripped power outlet or overloaded power strip, the monitor stuck in standby not receiving a video handshake, Eco Mode or a deep-sleep setting holding it off, and a firmware or internal board fault. Fixes in order: reseat the power and video cables, test another outlet directly, power-cycle by unplugging 30 seconds, wake it with the joystick / check the standby LED, disable Eco Mode, and test the panel on another device before returning it.

Causes Windows defaulting a new display to 60Hz, a cable whose bandwidth can't carry 2560x1440 at 144Hz (HDMI 1.4 is the usual bottleneck), plugging into the wrong monitor port, the 144Hz option hidden by the display driver at the OS level, and an in-game frame cap masking the change. Fixes in order: use a good DisplayPort or HDMI 2.0 cable on the right port, raise the refresh rate in Windows Advanced display settings, enable it in the GPU control panel, update drivers, and remove in-game frame caps.

Causes the display being driven below its native 144Hz refresh, a loose or damaged DisplayPort/HDMI cable, FreeSync (Adaptive-Sync) fluctuation flicker near the bottom of the variable range, the MBR (Motion Blur Reduction) strobe backlight, and incompatible GPU drivers or overlay apps. Fixes in order: set 144Hz, swap the cable, toggle FreeSync and MBR in the OSD, update the GPU driver, and power-cycle.

Causes the monitor's active input source not matching the cable in use, a loose or damaged DisplayPort/HDMI/VGA cable, connecting to the motherboard instead of the graphics card, a DP handshake failure on boot or wake-from-sleep, a resolution or refresh the link cannot carry, and PC-side boot problems. Fixes in order: power-cycle correctly, pick the right input, reseat the cable, use the GPU output, recover from sleep, and lower the resolution.

Causes the Q27G2's VA panel being intrinsically slow on dark-to-dark transitions, overdrive set too low, the monitor running below its native 144Hz (which magnifies motion blur), FreeSync/Adaptive-Sync off, and overdrive set so high it causes overshoot (inverse ghosting). Fixes in order: set Overdrive to Strong or Medium, run at 144Hz, enable FreeSync, cap fps, and test on the UFO ghosting test.
