Windows isn't displaying 1440p resolution.
Searching online recommends verifying whether "Ultra HD Deep Color" is activated on that HDMI port since it might be necessary for 1440p playback. Accepted, a 3070 would likely work with HDMI 2.1 through a direct connection to the dGPU, though not via an iGPU.
The issue likely stems from a mismatch in HDMI port specifications—your laptop might use 2.1 instead of 2.0, which is the minimum required for G-sync support. Because it lacks a MUX switch, you’ll need to update the drivers for your integrated graphics card.
I refreshed the drivers and the adrenalin software now shows just my laptop screen at 1080p240. My TV isn’t displaying anything. It works only in Windows and the Nvidia control panel, which confirms Gsync is enabled via HDMI.
Remove NVIDIA GeForce Experience and its graphics driver from your control panel. Clear all related files for complete elimination. Use the Display Driver Uninstaller to fully delete the Nvidia drivers. After confirming removal, restart your device. Reinstall GeForce Experience and update to the newest drivers. Then check the manufacturer’s website for the most recent BIOS or firmware updates—reinstalling Windows won’t alter your hardware’s firmware version.
