@tvshacker this monitor has a g-sync module and as such does not support freesync at all - I only used it with nvidia GPUs
this is what official manual has to say:
G-SYNC Monitor
• The monitor is purposely supporting the NVIDIA G-SYNC technology and targeting NVIDIA GPU.
• Requirement for using G-SYNC
- Supported Interface: DisplayPort (System must support DisplayPort 1.2 directly from the GPU.)
- Supported Graphic Card: A graphic card that supports NVIDIA’s G-SYNC is necessary.
and in order for this monitor to be updated, you need to use the (USB) service port on the back - as far as I am aware, LG did not push out any updates for this monitor (at least not to consumers directly so we could update it ourselves)
so in order to update this monitor you need to send it to LG - but I am not aware of any updates ever being released for this monitor
I still use it as my daily monitor (for gaming and office work) since I bought it (4 years ago?) and its still going strong
if you want freesync, there is a freesync variant of this monitor:
