ViewSonic lists approximately 37 ms input lag, which may be acceptable for casual play but is not competitive with modern gaming projectors built around much lower-latency modes. The old page also treated high brightness as proof of strong performance in any well-lit environment. Brightness helps, but ambient light, screen material, room geometry and image size all affect usable contrast.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_the_PX747-4K_still_worth_using\"><\/span>Is the PX747-4K still worth using?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you already own one and the lamp, color wheel, fan and inputs are healthy, there is no reason to replace it simply because newer models exist. Its 3,500-ANSI-lumen rating and 4K UHD output can still make it useful for movies, sports and general viewing in a controlled room.<\/p>\n<p>For a second-hand purchase, check lamp hours, brightness uniformity, color-wheel noise, fan noise, HDMI reliability, dust or optical artifacts, remote availability and the cost of a genuine replacement lamp. Also confirm that its 1.47\u20131.76 throw ratio fits your room before buying.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Where_current_buyers_should_look_instead\"><\/span>Where current buyers should look instead<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>BrandLigo now separates projector recommendations by use case instead of treating one older model as suitable for everyone.<\/p>\n<ul>\n<li>For current cinema-focused choices, see <a href=\"https:\/\/www.brandligo.com\/blog\/best-4k-home-theater-projector-2026\/\">Best 4K Home Theater Projectors in 2026<\/a>.<\/li>\n<li>For newer low-latency choices, see <a href=\"https:\/\/www.brandligo.com\/blog\/best-projector-for-gaming\/\">Best Projectors for Gaming in 2026<\/a>.<\/li>\n<li>For lower-cost 4K options, see <a href=\"https:\/\/www.brandligo.com\/blog\/best-4k-projector-under-1000\/\">Best 4K Projectors Under $1,000 in 2026<\/a>.<\/li>\n<li>For resolution trade-offs, see <a href=\"https:\/\/www.brandligo.com\/blog\/4k-projector-vs-1080p\/\">4K Projector vs 1080p in 2026<\/a>.<\/li>\n<li>For workplace and procurement requirements, see <a href=\"https:\/\/www.brandligo.com\/blog\/best-projector-for-business-presentations\/\">Best Projectors for Business Presentations 2026<\/a>.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Bottom_line\"><\/span>Bottom line<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The PX747-4K remains a useful legacy reference, especially for owners or buyers evaluating a used unit.
