Highlighted rows differ. Figures come from each product's sources; room depth, distances and brightness are FOREference calculations using the same method for both.
Which should you choose?
BenQ AH30ST
Choose the BenQ AH30ST if you prefer its maker, seller or ecosystem — the published figures do not favour it.
Optoma ZH350ST
Choose the Optoma ZH350ST if your room has ambient light or a large screen or you need to mount it close to the screen.
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.
