Conclusion​

Product	PROS AND CONS​
Optoma GT2100HDR​	Pros: • Aesthetically appealing design • Achieves clear and colorful picture quality similar to good 4K setups after calibration • Excellent response time for gaming • "Resync" feature helps with gameplay stability Cons: • Requires extensive calibration compared to other projectors • Initial hot plastic smell that dissipates after use • "Resync" feature may feel like a workaround rather than a solution • Occasional freezing and digital glitches upon initial use • HDMI1 port failures and limitations on 4K/HDR output • Did not include a carrying case as advertised Overall Impression: The GT1080HDR projector offers impressive image quality and gaming performance, but it demands significant effort to calibrate effectively. While it surpasses some competitors in potential quality, issues with HDMI connectivity and the initial setup experience can detract from its appeal. Users who prefer a plug-and-play experience may find better alternatives.

Its keystone correction feature adds versatility, while its solid performance in various lighting conditions further enhances its appeal. Overall, it represents excellent value for its price point.
