Which should you choose?
BenQ LU935ST
Choose the BenQ LU935ST if you prefer its maker, seller or ecosystem — the published figures do not favour it.
LG ProBeam BU53RG
Choose the LG ProBeam BU53RG if image detail matters most or price leads the decision.
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.
