How Should LED Wall Brightness Be Accepted for the Intended Room?

Quick answer

Treat brightness as a specification to be agreed, not a headline number to be compared. Ask each bidder to state the exact model and the brightness figure with its measurement condition, then agree in writing where and how the delivered wall will be checked in the actual room. Planar Komodo Series, for instance, lists Brightness Max, Calibration On (cd/sq) at 1,000 nits, so that value is tied to that series and to the calibration-on condition. Your acceptance should reference the named model, the agreed preset, the agreed measurement points and the room lighting at the time of the check. (planar-komodo-series-brochure-3-2026)

Why a headline brightness number is not an acceptance criterion

A brightness figure quoted in a brochure or a chat reply usually describes one named product under one stated condition. Planar Komodo Series, for example, lists Brightness Max, Calibration On (cd/sq) at 1,000 nits, and the same specification table lists a contrast ratio of 12,000:1 for that series. Those values describe that series and that condition. They do not describe another pitch, another brand or another room. (planar-komodo-series-brochure-3-2026)

The room also changes what a brightness figure means. Planar describes the Komodo Series as intended for the most visually discerning indoor applications, and describes DirectLight Ultra Series as suited to mission-critical environments where displays need to withstand extended or continuous operation day and night. A wall that runs all day in a bright lobby and a wall that runs overnight in a dim control room are different acceptance problems even if the quoted brightness is identical. (planar-komodo-series-brochure-3-2026; planar-directlight-ultra-series_brochure-6-25)

That is why the practical move is to accept brightness against an agreed method rather than against a single number. The method should name the model, the preset, the room lighting and the measurement positions, and it should be written into the order before shipment. (planar-komodo-series-brochure-3-2026)

What to ask the supplier to put in writing

Ask for the exact model name and pitch, not a family description. Planar Komodo Series is offered as Komodo 0.7, Komodo 0.9 and Komodo 1.2, with the specification table listing pixel pitches of 0.75mm, 0.9375mm and 1.25mm respectively. A brightness commitment should identify which of those models is being supplied. (planar-komodo-series-brochure-3-2026)

Ask for the brightness figure together with its condition. The Komodo Series specification table states Brightness Max, Calibration On (cd/sq) at 1,000 nits, which tells you the value is a maximum with calibration on. Request the same style of statement for the offered model, and ask whether the figure changes at other presets or after calibration. (planar-komodo-series-brochure-3-2026)

Ask how the wall will be measured in your room. Agree the measurement instrument, the distance and angle from the wall, the number and location of measurement points, the content shown during the check, the room lighting at the time, and who performs the measurement. Then state the acceptable result in the order so that acceptance is a comparison against an agreed method, not a debate about a marketing figure. (planar-komodo-series-brochure-3-2026)

Brightness, contrast and viewing conditions belong together

Brightness alone does not describe how a wall will look. Planar Komodo Series lists a contrast ratio of 12,000:1 alongside its brightness figure, and Planar DirectLight Ultra Series is described as delivering better overall contrast and deeper blacks through its MicroLED design. When you accept brightness, ask for the contrast figure for the same named model so the two are judged together. (planar-komodo-series-brochure-3-2026; Planar DirectLight Ultra | Planar)

Viewing angle and uniformity also affect perceived brightness across a wall. Planar describes the Komodo Series advanced manufacturing process as unlocking richer color uniformity and broader viewing angles, and describes the DirectLight Ultra Series ActivAlign alignment technology as maintaining high visual performance over time by combating vibration and thermal expansion that can cause LED modules to shift. Ask the supplier to include uniformity and viewing-angle checks in the same acceptance session as the brightness check. (planar-komodo-series-brochure-3-2026; planar-directlight-ultra-series_brochure-6-25)

For rooms where cameras operate, brightness interacts with capture. Planar DirectLight Ultra Series is described as HDR ready, with displays ready for High Dynamic Range content. If your room includes camera work, ask the supplier to demonstrate the wall on camera at the planned settings as part of the same acceptance visit, and record the result alongside the brightness measurement. (Planar DirectLight Ultra | Planar)

Room conditions to record before you sign

Record the ambient light in the room at the times the wall will actually be used, including daylight, artificial lighting and any direct light falling on the screen. Planar DirectLight Ultra Series is described as designed for mission-critical environments where displays need to withstand extended or continuous operation day and night, so the acceptance should reflect the operating schedule you will really run. (planar-directlight-ultra-series_brochure-6-25)

Record the operating environment the supplier is committing to. The Planar Komodo Series specification table lists an operating temperature and humidity range of 0°C to 40°C, 32° to 104° F, up to maximum operating temperature, 10-80% relative humidity, non-condensing. If your room sits outside the range you are relying on, raise it with the supplier before ordering rather than after installation. (planar-komodo-series-brochure-3-2026)

Finally, record what the wall will show. A wall used for detailed dashboards, a wall used for video and a wall used for large text place different demands on the same brightness figure. Ask the supplier to run your actual content during the acceptance check so the result reflects the intended room rather than a test pattern. (planar-komodo-series-brochure-3-2026)

Brightness acceptance decisions and the evidence to request

Buyer checklist

• Ask each bidder to name the exact model and pitch being offered, rather than a product family, so the brightness commitment attaches to one product. (planar-komodo-series-brochure-3-2026)
• Request the brightness figure together with its stated condition, in the style of the Planar Komodo Series Brightness Max, Calibration On (cd/sq) at 1,000 nits entry. (planar-komodo-series-brochure-3-2026)
• Request the contrast ratio for the same named model so brightness and contrast are accepted together. (planar-komodo-series-brochure-3-2026)
• Agree a written measurement method covering instrument, distance, angle, measurement points, content shown, room lighting and who performs the check. (planar-komodo-series-brochure-3-2026)
• Record the room operating conditions and compare them with the operating temperature and humidity range stated for the offered model. (planar-komodo-series-brochure-3-2026)
• Run your own content during the acceptance visit so the brightness result reflects the intended room and use. (planar-komodo-series-brochure-3-2026)

Frequently asked questions

Can I accept a wall using only the quoted brightness figure?

No. A quoted figure describes a named product under a stated condition. The Planar Komodo Series specification table, for example, states Brightness Max, Calibration On (cd/sq) at 1,000 nits, which ties the value to that series and to calibration being on. Accept the delivered wall against an agreed method in your own room instead. (planar-komodo-series-brochure-3-2026)

Should brightness be checked at maximum or at the level we will actually use?

Check both. Ask the supplier to demonstrate the maximum and the preset you intend to run day to day, and record the room lighting at each. The Komodo Series figure is stated as a maximum with calibration on, so the day-to-day preset is a separate question you should settle in writing. (planar-komodo-series-brochure-3-2026)

Does brightness acceptance also cover how the wall looks over time?

It should be part of the same conversation. Planar describes DirectLight Ultra Series ActivAlign technology as maintaining high visual performance over time by combating vibration and thermal expansion that can cause LED modules to shift. Ask how uniformity and alignment will be checked after installation, not only at first power-on. (planar-directlight-ultra-series_brochure-6-25)
