[REVIEW] Ustym 4K OTT X
The uClan Ustym 4K OTT X (and its satellite variant, the S2 OTT X) is a streamlined, high-performance streaming box that packs the power of the Ustym 4K PRO into a more compact, IPTV-optimized form factor. For enigma2.net, it’s a brilliant “bridge” device for users who prioritize streaming and OTT services but still want the flexibility of a Linux Enigma2 core.
## Full Review: uClan Ustym 4K OTT X
The OTT X is essentially a specialized version of the Ustym series designed for the “Over-The-Top” (OTT) market. It features a slightly updated processor and a heavy focus on the Denys_OS experience, while maintaining the Multiboot capability that Enigma2 fans love.
## 1. Updated Hardware Architecture
The OTT X moves away from the MV200 chip used in the PRO and utilizes the Hisilicon Hi3798MV300H quad-core processor.
-
Processing Power: Delivers a solid 15,000 DMIPS, ensuring that 4K menus and complex IPTV portals load with near-zero latency.
-
Memory & Storage: Equipped with 1GB DDR3 RAM and 4GB eMMC Flash. While the flash is smaller than the 8GB found in the PRO, it is still sufficient for a Dual-Boot setup between Denys_OS and a clean Enigma2 image like OpenATV.
-
4K UHD: Full support for 4K @ 60fps, HDR10, and HLG. The decoding efficiency for H.265 (HEVC) is top-tier, making it ideal for high-bitrate 4K IPTV streams.
## 2. Software: The Best of Both Worlds
The “X” series shines in its software versatility. It is designed to be user-friendly out of the box but “hackable” for the enthusiast.
-
Denys_OS (Factory Default): This is the star of the show. It’s a dedicated Linux OS with a multi-page launcher, customizable app icons, and deep integration for Stalker, Xtream, and M3U playlists.
-
Enigma2 Support: Despite being marketed as an OTT box, it fully supports Enigma2 Multiboot. You can import your E2 channel settings directly into Denys_OS or boot into a full Enigma2 environment.
-
Chromium Browser: Includes a stable Chromium-based web browser with mouse and keyboard support, making it one of the few Linux boxes that can handle modern web-based media portals effectively.
## 3. Connectivity & Remote Control
The OTT X is a smaller unit, but it retains the essential “pro” connections:
-
Networking: 10/100 Mbps Ethernet. While not Gigabit like the PRO, it is more than enough for 4K streaming (which typically tops out at 25-50 Mbps). It supports external USB WiFi and 3G modems.
-
Remote Control: Ships with the uClan Premium RCU v2.3, a learning remote that allows you to control your TV’s basic functions (volume/input) and includes 4 programmable “hotkeys” for launching your favorite apps instantly.
-
Ports: 2x USB 2.0 ports, HDMI 2.0a, SPDIF digital audio, and a composite AV jack.
-
Stealth Install: Includes an external IR receiver in the box, allowing you to hide the box behind a TV or inside a cabinet while maintaining remote control functionality.
## Pros and Cons
| Pros | Cons |
| IPTV Excellence: Denys_OS is arguably the best non-Android IPTV interface. | No Gigabit LAN: 10/100 Ethernet only (though sufficient for streaming). |
| Dual-Boot: Flexible choice between Denys_OS simplicity and Enigma2 power. | 4GB Flash: Tighter space for picons/plugins compared to the 4K PRO. |
| Web Browser: Chromium support is a major plus for web-based content. | No USB 3.0: File transfers from external drives will be slower. |
| Learning Remote: High-quality remote that can control your TV. | No Internal Tuner (OTT model): The base OTT X is for streaming only. |
## Final Verdict
The uClan Ustym 4K OTT X is the perfect “Smart TV” replacement for the Enigma2 enthusiast. It’s faster and more reliable than most Android sticks, and it offers a much more professional IPTV experience through Denys_OS.
Best For: Users on enigma2.net who want a compact 4K streaming box that can still run their favorite Enigma2 images, or for those who need a high-quality “Stalker” portal client.
