Which should you choose?
BenQ LU960ST2
Choose the BenQ LU960ST2 if you prefer its maker, seller or ecosystem — the published figures do not favour it.
Optoma ZK608TST
Choose the Optoma ZK608TST if your room has ambient light or a large screen or image detail matters most.
Before you buy either
- Check the room: room size calculator and ceiling height calculator.
- Confirm what each seller includes — accessories, software trials and bundles change often.
- Read the limitations on each full reference page.
