As professional video editors and colorists, we demand monitors that deliver accurate color, fine detail, and flawless performance. The TVLogic LUM-310X-CI is designed precisely for that — a high-end 31″ 4K HDR reference monitor built for critical post-production, live broadcast, and color grading workflows. In this blog post I’ll break down its key features, highlight how it fits into a color-grading pipeline (particularly relevant for DaVinci Resolve users), and look at pros & cons to help you decide if it’s right for your setup.
Key Features & Specs
4K / 31″ Size

True HDR with 1000 nit & 1,000,000:1 Contrast
The panel uses a dual-layer technology allowing a peak brightness of ~1000 nits and black level down to 0.001 nits, yielding an incredible contrast ratio of 1,000,000:1. tvlogic.tv
Wide color gamut: covers 100% of BT.709, 99% of DCI-P3, and 86% of BT.2020. tvlogic.tv
Meets the requirements of HDR Grade 1 monitors per EBU Tech.3320 (version 4.1) — making it appropriate for high-end HDR deliverables. tvlogic.tv+1
Advanced Color Engine: LogiColor
Uses an FPGA based ‘LogiColor’ engine which transforms 10-bit non-linear Y′C_C input into 24-bit linear RGB (72-bit per pixel) for superior mid-tone and highlight/shadow fidelity. tvlogic.tv
Enables preset modes for HD, UHD, DCI, PQ, PQ2, HLG, plus 6 user modes. Also supports gamut mapping (BT.709, DCI-P3, BT.2020, Native) and color temperature selection (D65, D93) etc. tvlogic.tv
Calibration & LUT Support
Comes with proprietary calibration software ‘LogiCAL’ for PC & Mac. Calibration produces 1D and 3D LUTs, and generates a PDF (or HTML) report including delta E data, gray level graphs, etc. tvlogic.tv+1
Uses high-accuracy probe method (Multi-Color Matching with 80 color samples) rather than traditional 4-color matrix. tvlogic.tv
Zero Video Latency for 4K Signals
Uses DRC (Dynamic RAM Control) technology to reduce internal processing latency. For 4K/60p and 4K/50p via single-link 12G-SDI, latency is ~0.2 frame (virtually zero) after firmware update. tvlogic.tv
Ideal for live broadcast, camera monitoring, and real-time workflows where latency matters.
Robust Input/Output Options
12G-SDI single-link (2-sample interleave division) for input and through-output. Also supports quad-link 3G-SDI and HDMI 2.0. tvlogic.tv
Supports 3G-SDI Level A/B. Embedded audio level meter, UMD display, waveform/vector scope monitoring, range error indication, markers, closed caption support. tvlogic.tv
Other Pro Features
Super-White support (‘Narrow 109’) lets you monitor up to ~120 nits white levels above 100%. tvlogic.tv
Gamut Warning and Native Mode (bypass processing to inspect raw signal). tvlogic.tv
Built-in key lock for OSD menu, H/V delay check, audio level display, etc. tvlogic.tv
Why this monitor matters for color-grading & broadcast workflows
Since you’re a seasoned post-production manager and trainer (especially with DaVinci Resolve), the LUM-310X-CI ticks a lot of boxes:
For HDR grading: With 1000 nits peak and BT.2020 gamut coverage (86%), it allows you to conform to HDR deliverables rather than just “HDR emulation”.
Calibration & LUT support means you can integrate it into a certified workflow where color accuracy is critical (e.g., client deliverables, broadcast).
Low latency is beneficial if you’re also doing live streaming or monitoring camera feeds for live broadcast.
Multiple inputs + scopes + professional features means it can carry double duty (monitoring + grading) in your digital-media/live-broadcast business.
As a trainer, being able to show students a “true HDR reference monitor” will strengthen your credibility and differentiate your setup.
Potential Drawbacks / Considerations
At 31″ and 4K resolution, you’ll want sufficient desk space and proper viewing distance (~1 m or more) to fully appreciate the resolution and calibration.
A peak of ~1000 nits is excellent, but if you were aiming for super-high HDR workflows (2000 nits+), there are other monitors that exceed that. The LUM-310X-CI covers “true HDR” but might not reach ultra-high brightness for extremely bright effect work.
As a professional reference monitor, cost will be high (though I don’t have the exact price here) — it may be overkill if you’re only doing simpler Rec.709 SDR work.
Calibration and firmware update are required steps to achieve optimal performance — requires some time and proper probes. The website indicates that if you upgrade firmware you should recalibrate. tvlogic.tv
Conclusion
If you’re looking for a serious professional-grade reference monitor for HDR and SDR work, especially in post-production and broadcast environments, the TVLogic LUM-310X-CI stands out as a strong choice. Its accurate color engine, full calibration support, very low latency and advanced features make it a highly credible tool for color grading and broadcast workflows. For your YouTube content, training on color grading in DaVinci Resolve, live streaming and high-end editing work, this monitor will serve as an excellent centerpiece of your setup.
