Conclusion​

Product	PROS AND CONS​
Optoma HD30LV​	Pros • Bright picture quality, suitable for daytime use • Good performance typical of Optoma projectors • Nice picture clarity for meetings in large spaces • Factory reconditioned unit appears to be in good condition Cons • Misleading marketing with images suggesting it's a laser projector • Limited resolution of 1080p • Non-adjustable rear feet can be a drawback • Keystone correction feature is ineffective • Weak built-in speaker, requiring an additional purchase for better audio • Noticeable fan noise during daytime use • Missing lens cap upon delivery • Poor quality remote control Overall Impression The projector delivers bright and quality visuals, making it a solid choice for daytime presentations in large spaces. However, limitations such as the lack of adjustable feet, weak sound output, and ineffective keystone correction detract from the overall experience. The misleading marketing regarding laser technology may also leave some customers feeling disappointed. While it performs well for its intended use, potential buyers should weigh these factors against their specific needs.
ViewSonic PX701-4K​	Pros: • Super bright picture that is viewable in daylight or soft dim light • High quality picture with beautiful colors • Smooth gradients and grayscales • Good on-screen menu for easy navigation • Responsive remote (backlit version available with PX 748 model) • Smooth zoom and focus ring for easy adjustment • Very sharp picture from corner to corner • Auto Keystone feature saves time and effort • 3 years warranty Cons: • Defective unit raises concerns about quality control Overall Impression: Despite the initial issue with a defective unit, the second projector proved to be stunningly bright and high-quality, making it a strong contender in the 4K projector market under $1000. Its impressive features and performance earn it a solid recommendation.
