Gaming Response And Room Fit
Controller response, room lighting, and projector placement can shape your gaming setup as much as resolution. A low-latency gaming projector may suit fast console play, but the listed input-lag figure and picture mode still matter. The supplied products include several 1080p models, yet refresh-rate details are incomplete, so you should verify the supported resolution and refresh-rate combination for your console or PC. This review of the benq th671st 1080p short throw gaming projector category keeps those limits visible instead of treating broad gaming labels as proof of every feature.
BenQ TH575i lists 16.7ms input lag, a Game mode, 3,800lm brightness, 1.1x optical zoom, and Auto Vertical Keystone. The renewed BenQ TH671ST lists 16.67ms input lag, native 1080p, 3,000 ANSI lumens, a 100-inch image from 1.5 meters, and an ambient-light sensor. The other TH671ST listing specifies native 1080p, 3,000 lumens, a 100-inch image from 5 feet, projection up to 300 inches, and dual HDMI, while Optoma adds ultra-short-throw placement, HDR10, Google TV, and a built-in battery. For connection basics, see this guide on connecting a computer to a projector, and check your source device before buying.

FAQs
Which projector lists a specific input-lag figure?
BenQ TH575i lists 16.7ms, while the renewed BenQ TH671ST lists 16.67ms. The supplied information does not provide a measured lag result for the other TH671ST listing or the Optoma model.
Do these projectors support 1080p gaming?
Several listings specify native or Full HD 1080p, including both TH671ST models and Optoma ML1080UST. The available data does not establish every supported input mode, so verify the console or PC output settings before purchase.
Is a refresh rate provided for console gaming?
A refresh-rate detail is not fully stated for most products. The second TH671ST listing says its refresh rate matches the maximum output of Xbox One X and PS4 Pro, but it does not provide a numeric refresh rate in the supplied information.
Which model has a dedicated gaming picture mode?
BenQ TH575i explicitly lists Cinema, Sports, Game, and 3D modes. The supplied details do not identify a dedicated gaming mode for the other three projectors.
Which projector suits a small room or tight setup?
Optoma ML1080UST is specified to create a 100-inch image from less than one foot away. The TH671ST listings also provide short-throw distances, while TH575i adds 1.1x optical zoom and Auto Vertical Keystone for placement flexibility.
Do the listings confirm HDMI features or HDR?
The second BenQ TH671ST listing explicitly includes dual HDMI, and Optoma lists HDR10 support. HDMI versions, bandwidth, VRR, ALLM, and eARC are not provided, so verify those details for your console or PC. For more connection guidance, see how to connect a MacBook to an HDMI projector.
About the author
For me a gaming projector lives or dies on lag and refresh rate, not on a big brightness claim. I write about consoles and PC on a big screen: what the input lag figures really mean, which resolution and refresh combinations are worth chasing, and which modes quietly add delay. I read spec sheets and owner feedback with a skeptical eye and I try to explain the catch behind every headline feature. My notes follow the site's review methods: research-based comparison, not lab testing.
