For those of you who were eager to see if the LG 34GK950F-B works with GSync, then good news folks! We can confirm that the LG 34GK950F-B does indeed work with GSync when enabled from the NVidia control panel.
No flickering or artifacts were noticed when running Pendulum Test, Doom 3, Fortnite, PUBG and CS:GO using a GTX2080Ti and an Intel Core i7 9900-K.
This might not be surprising since the LG 34GK950F-B uses the same panel as its sibling the LG 34GK950G. More specifically, the Freesync version also boasts better specs than its the Gsync counterpart. However, by choosing the LG 34GK950F-B you will be missing out on the RGB lighting which the LG 34GK950G has. Nonetheless, you will be able to get 144Hz, better colour depth, HDR400 and MBR mode with the Freesync 34GK950F-B monitor, which the 34GK950G doesn’t have.
