Conclusion​

Product	PROS AND CONS​
Optoma GT2100HDR​	Pros: • Aesthetically appealing design • Clear and colorful picture quality when properly calibrated • Amazing response time for gaming • Resync feature helps with minor gameplay issues Cons: • Requires extensive calibration compared to competitors • Initial hot plastic smell during first usage • Resync feature may feel unnecessary • Occasional freezing issues, particularly with HDMI1 port • Limited HDMI 1.4 capabilities affect 4K/HDR performance • Did not come with a carrying case as advertised Overall Impression: The GT1080HDR projector offers impressive quality and gaming performance, but it demands significant calibration effort and may have reliability concerns, particularly with HDMI functionality. While it surpasses the HT2150ST in potential, the initial setup challenges and occasional technical issues may deter those seeking a straightforward experience.
ViewSonic LS711HD​	Pros • Great price for the quality • Good build quality • Heavy, suggesting durability Cons • Luminance significantly lower than advertised (60% of competitor) • Performance not matching expectations compared to similar models • Multiple units showed the same issue Overall Impression The product offers a competitive price and solid build quality, but fails to deliver on brightness performance compared to other projectors in its class. This discrepancy in luminance may lead to disappointment for users expecting high brightness levels.
