The Epson TW8300 ($2,699) and the Optoma UHD660 ($2,499) are two top-tier home theater projectors that deliver impressive 4K and HDR performance, with vibrant colors and excellent contrast. While both offer high-quality visuals, they differ significantly in features and design, making them suitable for different needs.
One key difference is 3D support: the TW8300 offers full 3D, while the UHD660 lacks this feature unless a firmware update is applied. Additionally, only the UHD660 allows frame interpolation at 4K or 1080p inputs, which can enhance motion clarity. The choice between these models ultimately depends on what features matter most to you.
When it comes to imaging technology, the UHD660 uses a true 4K DLP chip, delivering 3840x2160 pixels, while the TW8300 relies on a 1080p 3LCD chip with pixel-shifting 4K enhancement. Though the TW8300 doesn't have native 4K resolution, its enhanced image quality is visually comparable, especially for movies. However, the UHD660's higher pixel count gives it an edge in detail when viewing text or photos, though this isn’t typically a concern for most users.
In terms of lens quality, the TW8300 features a 2.1x zoom lens with all-glass optics, offering superior optical quality and precision. It also includes motorized focus, zoom, and lens shift, along with a lens memory function that stores up to 10 settings. This makes it more flexible for installation and ideal for those who want to switch aspect ratios easily without anamorphic lenses. In contrast, the UHD660 has a smaller vertical lens shift and no trapezoidal correction, making it less versatile for placement.
For 3D enthusiasts, the TW8300 supports full 1080p 3D via RF glasses, while the UHD660 currently lacks 3D support (though a future firmware update may add limited 3D capabilities). If 3D is important to you, the TW8300 is the better option.
Regarding upscaling, the UHD660 automatically converts all inputs to 2160p and applies image processing to every signal. The TW8300 enhances 4K content but disables frame interpolation when 4K enhancements are active, limiting some motion handling options.
Image quality varies depending on the input type. For 4K HDR, the UHD660 outperforms the TW8300 with brighter images, better shadow detail, and more accurate color reproduction. It also allows full use of frame interpolation and noise reduction on 4K signals. On the other hand, the TW8300 delivers slightly sharper images for 1080p SDR content and deeper blacks, making it a better choice for standard dynamic range videos.
Both projectors offer good factory settings, but the UHD660’s color menus are easier to navigate, while the TW8300 provides more neutral defaults. The UHD660’s brightness is slightly lower than the TW8300, but it still performs well for home theater use.
In terms of performance, the TW8300 measures over 3500 ANSI lumens in its brightest mode, far exceeding its nominal rating. The UHD660, on the other hand, peaks at around 1700 ANSI lumens, which is still sufficient for most environments. Both projectors experience brightness loss when using the telephoto end of their zoom lenses, so placing the projector closer to the screen is recommended for maximum brightness.
The TW8300 has a much better brightness uniformity (93%) compared to the UHD660 (59%), making the former more consistent across the screen. However, the UHD660’s image uniformity is less noticeable in most video content due to the complexity of the scenes.
Rainbow effects are a concern for single-chip projectors like the UHD660, but they are rare and not typically distracting. The TW8300, being a 3-chip model, avoids this issue entirely.
Audio-wise, the UHD660 includes built-in 4W speakers, making it more convenient for casual setups, while the TW8300 requires an external audio system.
Input delay is another factor. The TW8300 has a low latency of 28ms in 4K enhanced mode, while the UHD660 has a longer delay when frame interpolation is enabled.
Noise levels are relatively quiet for both, with the UHD660 being slightly quieter in Eco mode. However, the TW8300’s noise is still acceptable in most environments.
Ultimately, both projectors are excellent choices, but each excels in different areas. The TW8300 is more flexible in setup and offers better 3D and 1080p performance, while the UHD660 shines in 4K HDR and offers superior frame interpolation. Your decision should be based on your priorities—whether you value 3D, HDR, or installation flexibility.
