I have never had this resolution available (I have an AMD Ryzen 7 5800h on Lenovo Ideapad 5 Pro 16") neither can I create a custom resolution on AMD Radeon / Adrenalin Edition settings like I have seen other solutions provide. A 'Display' tab also does not show up in NVIDIA Control Panel.
I can provide any information required, I have the latest drivers and everything, I've checked.
