A useful color gamut claim names the reference colour space and whether the figure is coverage of that space or gamut area on a stated diagram. A percentage alone is incomplete. sRGB, NTSC and P3 percentages are not interchangeable conversions — rank them in one column and you compare unlike methods.
Four confirmations before you compare quotes
- Compare the same reference space. Require the full name (sRGB, NTSC, DCI-P3, Display P3, Adobe RGB, etc.). Unlike percentages do not belong in one ranking column.
- Distinguish coverage from gamut area. Coverage answers how much of the named reference the panel can reproduce. Area compares relative sizes on a chromaticity diagram. Record which measure the quote uses.
- Test brand colours, neutrals and photographs through the intended player at the planned operating brightness — not only in design-software preview.
- Record model, picture mode, brightness and source-file settings used for approval, and whether the figure is typical or guaranteed for every size on the quote.
This guide shows how to read commercial display gamut claims, what to lock in an RFQ, and how to approve a screen with representative files. After you select the hardware line, match neighbouring panels with a measured process — see Display Color Calibration for Commercial LCD Video Walls. Bit depth is a separate topic: 8-Bit vs 10-Bit Color: What Commercial Signage Buyers Should Check. Near-view readability is not a gamut claim — use Pixel Density for Digital Signage: PPI, Resolution and Viewing Distance when viewing distance drives the brief.
Range vs accuracy vs consistency
| Requirement | What it answers | Evidence you need |
|---|---|---|
| Gamut (range) | Which colours the panel can reproduce, under a named reference and coverage/area method | Reference space name; coverage or area; chart or lab method; picture mode + brightness |
| Accuracy | How close a displayed colour matches its target under stated conditions | Targets, instruments and tolerances agreed before order when contractual |
| Consistency | Match across the screen, between units, or over time | Multi-unit side-by-side with the same files; measured neighbour match after install |
One brochure percentage cannot answer all three. In a retail project, write them as separate lines: the creative team cares about a logo red; the installer needs several screens to look alike; purchasing needs a repeatable record for a replacement unit.
For the basic definition of gamut and reference spaces, see EIZO’s colour gamut explanation (principle reference only). Commercial decisions on this page bind to YJCEN product lines, RFQ fields and acceptance notes — not to an external brochure figure.
Decision table A: when each reference space matters
| Reference space | Typical content source | Must ask when comparing quotes | How to write it in the RFQ | Hardware path after the figure is agreed |
|---|---|---|---|---|
| sRGB | Most web / office / retail campaign files exported for general digital signage; brand packs already tagged sRGB | Full name “sRGB”; coverage or area; chart/method; picture mode + brightness; typical vs guaranteed; same figure for every size in the quote | “Quote sRGB coverage (not area alone) for model X at picture mode Y and N nits; attach CIE chart or lab method; state typical/guaranteed; confirm all sizes in this RFQ.” | Multi-panel walls → LCD Video Wall, then neighbour match via display colour calibration. |
| NTSC | Legacy datasheets and some Asian supplier quotes still list “xx% NTSC”; rare as a modern design export target | Whether the figure is NTSC coverage or area; which NTSC region definition; treat NTSC% as its own labelled line, not as sRGB% or P3% | “Re-quote in the project reference space (usually sRGB or Display P3) with method + picture mode. Keep the original NTSC line only as supplier-supplied, labelled NTSC.” | Same product-line path: LCD Video Wall. Bit depth on the quote is separate — see 8-bit vs 10-bit; never swap bit-depth language for a gamut %. |
| DCI-P3 / Display P3 | Cinema-adjacent or HDR-ish campaign masters; Apple/web Display P3 assets; brand reds/oranges outside sRGB | Exact name (DCI-P3 vs Display P3 — not interchangeable on one quote line); coverage vs area; whether playback mode is a limited P3/HDR mode or a restricted signage mode | “Name DCI-P3 or Display P3 explicitly. Require coverage of that space at the playback picture mode and target brightness. List export colour space of masters and the intended player.” | Window / high-ambient jobs: assess colour with brightness under day and night — Digital Window Displays. |
| Adobe RGB | Print / photography workflows occasionally reused on lobby screens; uncommon as primary digital-signage master | Why Adobe RGB is required (usually it is not); whether content was actually exported Adobe RGB; coverage vs area | “Only if creative sign-off demands Adobe RGB masters. Otherwise specify sRGB or Display P3. If required: Adobe RGB coverage + mode + brightness + method; do not rank against NTSC% in one column.” | Near-view readability is not a gamut claim — link pixel density / readability when viewing distance drives the brief. |
Decision rule: NTSC% is not a direct substitute for sRGB% or P3%. Require the supplier to re-quote in the project’s reference space and method.
Decision table B: coverage vs area
| Topic | Fillable rule | What to do next on a YJCEN project |
|---|---|---|
| When you need coverage | Require coverage of the named reference when brand colours must fall inside that space (logo reds, packaging hues). Coverage answers: “How much of reference X can this panel reproduce?” | After the figure is agreed, multi-unit walls still need measured neighbour match — display colour calibration. A coverage % on a brochure does not replace calibration. |
| When area is only what the supplier gave | Area compares relative sizes on a stated chromaticity diagram. It can look “large” while missing part of the reference. RFQ action: keep the area line labelled “area only”, and require a coverage figure (or CIE diagram showing overlap) for the same reference + picture mode before sign-off. | Route the buyer to the correct hardware line first (LCD Video Wall or Digital Window Displays), then insist on method notes for the same reference + picture mode. |
| Unlike percentages stay labelled | Do not convert NTSC↔sRGB↔P3 percentages, and do not rewrite area as coverage with a home-made factor. Unlike regions and methods are not interchangeable. Ask the supplier to re-measure or re-state under the project’s reference and method. | Compare gamut percentages only when the reference colour space, measurement method and picture mode match. |
Picture mode must bind to the quoted figure
Ask which picture mode, brightness, and panel configuration produced the result. The maximum native range on a lab sheet often differs from the restricted mode used for playback on site. Record whether the number is typical or guaranteed, and whether it applies to every size and configuration in the quotation. Use the same mode for sample approval and for replacement units.
Select hardware from the LCD Video Wall range or the Digital Window Displays line as the project requires. Carry the quoted picture mode into sample approval and into the replacement-unit retest template.
Match content to the playback path
- Masters: Ask the designer which colour space was used and how images or videos were exported. Keep approved originals alongside delivery files.
- Player / app: Play the final files through the actual production system. A correct-looking preview in design software does not verify the installed path. Do not assume every signage player handles embedded image profiles the same way as a workstation.
- Display: Use the picture mode and brightness recorded for the quote. For a mixed playlist, include photographs, flat brand colours, gradients and video. If only one asset differs, compare its export settings before changing the entire display setup. If every asset differs, investigate common settings and the signal path first.

Sample evaluation and acceptance
Use the proposed commercial screen and player in an environment close to the installation. Keep room lighting stable during comparisons. Document reflections and viewing position rather than moving between conditions without notes.
- Select a small set of approved assets with important brand colours, neutral areas and natural photographs.
- Record file versions, export settings, player configuration and display picture mode.
- Play those files through the intended input at the planned operating brightness.
- Review from normal customer viewing positions, including any important side approach.
- For a multi-screen installation, compare units together using the same files and settings.
- If colour matching is a contractual requirement, agree on targets, instruments and acceptance tolerances before ordering.
Printed swatches can support a discussion with the creative team, but paper and illuminated screens are different media. A casual side-by-side is not a measured pass. Define the intended reference and viewing conditions when an exact colour decision matters.
Window / high-ambient jobs: assess colour with brightness under day and night conditions on the Digital Window Displays path. Do not sign off solely from a dark-room demonstration when the installed screen faces a bright shopfront.
YJCEN’s 3×3 55-Inch Video Wall for Furniture Store uses nine 55-inch panels. In a multi-panel layout, neighbouring screens should be compared for colour and brightness consistency. For the adjustment process, see display colour calibration.
Common mistakes
Choosing the largest number regardless of the application
A wider quoted range does not solve every signage problem. Confirm that the required colours and workflow are supported, then separate readability, installation conditions and operating requirements. An indoor menu board and a window-facing advertising screen have different priorities even when they share the same artwork. Near-view readability belongs under pixel density, not under a gamut ranking column.
Using a photograph as a gamut measurement
A photo of two screens includes camera exposure, processing and the device used to view that photo. It can document an observed mismatch. It does not establish measured gamut. Keep photos with settings and measurements; treat an attractive image as a note, not as a pass result.
Confusing colour count / bit depth with gamut
The number of available tone levels and the range those levels cover are separate properties. Bit depth or a quoted colour count is not a replacement for a gamut specification. See 8-bit vs 10-bit.

Does every signage project need wide gamut?
No. Start from the colours and files that must be reproduced through the real player. If the current workflow already meets agreed brand targets, a larger brochure number alone does not prove a useful on-site improvement. Separate near-view readability (pixel density) from gamut claims. Hardware choice still goes through the relevant YJCEN product line — LCD Video Wall or Digital Window Displays — with the RFQ fields above locked before order.
FAQ
What does a color gamut percentage mean on a commercial display datasheet?
It needs a named reference space plus coverage-or-area. Without those labels, do not rank unlike supplier claims in one column. Use the LCD Video Wall line and measured colour calibration for multi-unit match once method and picture mode are on the quote.
Can I convert NTSC % to sRGB % (or to P3) for a like-for-like quote?
No. Area and coverage describe different measurements. Ask for the percentage in the required reference colour space, with the measurement method, picture mode and brightness stated. Keep a legacy NTSC value labelled NTSC rather than converting it to sRGB or P3.
What is the difference between gamut, colour accuracy, and consistency?
Gamut is range under a named reference plus coverage or area. Accuracy is match to a target under stated conditions. Consistency is match across the screen, between units, or over time. One percentage cannot answer all three — multi-panel walls still need measured neighbour match via commercial LCD video wall colour calibration.
Which picture mode should match the quoted gamut figure?
The same named picture mode used for the quote. Bind operating brightness, panel configuration, and typical-vs-guaranteed to that mode. Site playback often differs from the lab “maximum native range” sheet — record the mode for sample approval and replacement retest on LCD Video Wall or Digital Window Displays.
What should go in the RFQ / acceptance pack for brand colours?
Lock models, sizes, reference space, and coverage or area. Add method, picture mode plus brightness, and typical vs guaranteed. Include master export space, player/app, asset list, viewing positions, multi-unit side-by-side if a wall, sign-off owner, and replacement retest template. Window jobs: day and night checks on Digital Window Displays; submit via Contact.
Does every digital signage project need a wide-gamut panel?
No. Start from the colours and files that must play through the real player. If the current workflow already meets brand targets, a larger brochure number alone is not an on-site improvement. Separate pixel density from gamut, then lock the RFQ fields above on the chosen YJCEN line.
