The laptop's screen permits alternative refresh rates exclusively when G-Sync is activated.
I own a ROG Zephyrus G16 (2023) laptop with a 165hz screen. In the NVIDIA control panel, I can only adjust to 165hz or 60hz. However, when I use DGA only in "manage display mode," I can access Windows settings and change the refresh rate to 60, 75, 100, 120, or 165hz. These options appear only in Windows settings and are available only when G-SYNC is enabled. This seems unusual—it doesn’t make much sense since it should work differently. Also, when I set it in Windows, there’s no confirmation message when I enable 75hz, 100hz, or 120hz. It’s confusing, and I haven’t tested a game to confirm the FPS. Is there anything I can do to make it recognize those rates in NVIDIA settings? The program that would normally handle this is likely the one managing GPU settings before basic Windows with IGUI.
Nvidia Advanced Optimus offers flexibility for you. You can choose between 60 or 240 options, and the settings are mostly self-adjusting during gameplay. A note on changing hertz shouldn't be a big issue since it will adapt automatically. G-Sync can be turned off without affecting performance, and I'm using a Predator PH315-55 Laptop.
I believe it's connected to Asus. There appears to be a code issue that blocks monitor access outside the 60hz/165hz range unless G-Sync is turned on. No other build I've tried forces this restriction to gain access to alternative settings. If you really wanted full control, you'd need to launch a game first before enabling G-Sync, then restart it without G-Sync active, and finally adjust the refresh rate manually in Windows Display settings to other values like 75hz/100hz/120hz while managing temperatures without using G-Sync. I had to enable G-Sync just to balance things out.
