Conclusion​

Product	PROS AND CONS​
Optoma HD39HDR​	Pros: • Mostly quiet operation • Good picture quality, especially for gaming (compatible with PS5) • Simple setup and control Cons: • Inaccurate lamp life claim (lamp failed after about 9,000 hours) • Limited warranty on the lamp (only 90 days) • Basic screen adjustment features • Occasional input connectivity issues Overall Impression: While this projector delivers impressive picture quality and ease of use, it falls short in terms of lamp longevity and warranty support. Consumers should be cautious of the lamp life claims and consider the basic features when making a decision. Despite some connectivity issues, it remains a recommendable option for those looking for performance at a reasonable price point.
Optoma HD28HDR​	Pros • Bright picture even in well-lit environments • Clear sound quality, especially when positioned nearby • Lightweight and easy to handle • Impressive HDR support, providing near 4K quality • User-friendly menus with adjustable settings Cons • Limited ceiling mount options requiring adjustments • Restricted keyhole adjustment capabilities • Noticeable fan noise when no sound is playing • Potential color wheel artifacts during quick eye movement Overall Impression This projector offers an excellent balance of brightness and picture quality, making it ideal for both bright and dark environments. While it has some limitations in terms of mounting options and slight visual artifacts, its impressive HDR capabilities and user-friendly features make it a strong choice for anyone seeking a budget-friendly alternative to true 4K projectors.
