Razer released BIOS 2.02 and GeForce 531.18 updates for the Blade 18 gaming laptop today, which fixes the problem that G-Sync and MUX are not supported when an external monitor is connected.
It was reported in February this year that after installing the NVIDIA 528.49 driver update, the Razer Blade 18 RTX 4070 no longer supports G-Sync with an external display, and the performance output of DLSS 3 is greatly reduced.
Razer also rolled out the GeForce 531.18 panel update today, which fixes the screen flickering issue. However, Razer has not yet fixed the problem that the performance of DLSS 3 is greatly reduced when the external display of the Blade 18 gaming laptop is connected.
Razer said it is still investigating the issue and will provide an update as soon as possible. Blade 18 users who don’t run games that support DLSS 3 on an external monitor need not worry.
