The Samsung Crystal UHD CU7100 is a mid-range TV targeting buyers seeking a balance between affordability and features. It boasts a 4K resolution display, smart TV functionalities, and a sleek design. This review will explore the CU7100’s strengths and weaknesses to help you determine if it aligns with your needs.


  • Good Picture Quality for the Price: The Crystal Processor delivers decent upscaling, enhancing the resolution of non-4K content. The VA panel offers good contrast, resulting in deeper blacks and richer colors compared to basic IPS panels.
  • Decent HDR Performance (for its class): While not top-tier, the CU7100 supports HDR10, HDR10+, and HLG formats. It can achieve peak brightness levels exceeding 300 nits, offering a noticeable improvement over SDR in terms of color vibrancy and contrast.
  • Low Input Lag for Gamers: The CU7100 boasts a low input lag, particularly in Game Mode, making it suitable for casual gamers who prioritize responsiveness over the fastest refresh rates found in high-end models.
  • Smart TV Features with Built-in Apps: The Tizen OS provides a user-friendly platform with access to popular streaming services like Netflix, Hulu, and YouTube.


  • Limited Viewing Angles: Similar to many VA panels, the CU7100 has limited viewing angles. The picture quality can suffer if you’re not seated directly in front of the TV.
  • Edge LED Backlight with No Local Dimming: The CU7100 utilizes an edge-lit LED backlight, which can lead to some blooming in dark scenes where bright objects appear to halo. The lack of local dimming further limits the TV’s ability to control backlight levels in different zones of the screen.
  • Average Sound Quality: The built-in speakers deliver a mediocre audio experience. For an immersive home theater setup, you’ll likely need a soundbar or separate sound system.


The Samsung Crystal UHD CU7100 offers a good balance between affordability and features for casual viewers who prioritize a 4K experience with decent HDR performance. It provides a user-friendly smart TV platform and caters to casual gamers with its low input lag. However, keep in mind the limitations in viewing angles, backlight uniformity due to the edge-lit design, and the average sound system.
