Odyssey Ark and Nvidia Surround

Has anyone been able to use Nvidia surround with the Samsung Odyssey Ark? I have the Ark as my main screen, a Samsung Q80A on the left, and a Samsung q80 on the right. I also have an Aurus RTX3080Ti video card. I've tried multiple different configurations over several hours without success. The closest I can come to matching resolution on all three is 2560 x 1440 on the left and right and 2560 x 1600 on the Odyssey Ark. At this setting, the refresh rate of the Ark won't go below 100 Hz and I can't bump the other two over 30 Hz or they give me a black screen. I also don't have the option of creating a custom setting on the Ark in the Nvidia control panel, it's greyed out. Any help would be appreciated.
