Conclusion​

Product	PROS AND CONS​
Optoma UHD38x​	Pros: • Excellent initial image quality • Good performance for movie watching • Solid brand reputation with previous model (S316) • Potential for high resolution gaming Cons: • Occasional color distortion and block lines • Dead pixels after a short period of use • HDMI connectivity issues, especially with gaming consoles • Bulb failure within 7 months • Lengthy and unresponsive customer service experience • Overall reliability concerns for the price point Overall Impression: While the Optoma UHD38 initially meets expectations with impressive image quality, significant reliability issues and connectivity problems have emerged relatively quickly. Coupled with disappointing customer service experiences, the projector may not justify its high price tag for potential buyers. Consider exploring alternative options before purchasing.
ViewSonic LX700-4K​	Pros: • Excellent picture quality, comparable to OLED in bright environments • Brightness makes it suitable for gaming and ambient light settings • Great value for the price, especially during sales • Laser light source longevity (4x longer than traditional bulbs) • Convenient features like trigger input and backlit remote • Compact design, not as deep as some competitors Cons: • Onboard speaker quality is subpar; external speaker recommended • Color accuracy not as good as some previous models (e.g., Epson 2250) • Limited zoom capability compared to other projectors (1.36x vs. 1.6x) • Annoying resolution detection dialog box that interrupts use • No noticeable sharpness improvement over lower resolution models at a distance Overall Impression: The projector delivers impressive performance for its price, especially in well-lit environments. While it excels in brightness and value, users may need to invest in an external sound system and consider the limitations in color accuracy and zoom capabilities. Overall, it is a strong choice for those transitioning from traditional TVs to a projector setup.
