Match the full model number
Check every letter and suffix, including the regional code. Similar names can refer to different panels, refresh rates or connection options.
Check the manufacturer's documentation
Look for a specification sheet or manual for the exact model and region. Check the resolution and refresh rate as a pair, then confirm which input supports that mode.
Confirm the offer before ordering
Ask the seller to confirm any feature that matters to your setup, along with the condition, delivery date and return policy. Keep a copy of the offer and your receipt.
