Check if the model on the unit is V4K50C-0809 or something very close (e.g., V4K50C-8090 could be a mis-typing or regional variant).
Verify that all the features you need (inputs/external ports, smart platform, game mode) match your requirement.
If you are replacing, mounting, or using it in a specific room: check the dimensions, mounting hole VESA pattern, wall clearances.
Consider warranty, return policy, and condition (new/open-box/used) especially if the model is slightly older or a variant.
