What actually separates the P-series from the T-series. Lenovo's own marketing puts the P-series under "Best-in-Class Performance for Leading Professionals" and the T-series under "Enhanced Productivity for Modern Taskers", but it never states in prose that colour accuracy is the dividing line. The evidence is in the specification sheets instead: most P-series models publish a factory calibration figure of Delta E under 2 and ship a printed calibration report in the box, and T-series models do not. That is the difference we are willing to stand behind, and it is why this page cites the per-model figure rather than a slogan.

What 5K2K actually gives you. 5120 x 2160 is two 2560 x 2160 halves side by side. Two application windows sit at genuinely usable widths with no bezel between them, and a 4K video timeline fits with panels either side. Against a 3440 x 1440 ultrawide you get about 50% more horizontal pixels and 50% more vertical — and at 140 dpi it is sharp enough that you are not trading detail for width.

The HDMI caveat, stated up front. This model uses HDMI 2.1 FRL rather than TMDS. FRL is what carries 5120 x 2160 at 120 Hz; a source or cable that only does TMDS will not reach that mode. Over Thunderbolt 4 or DisplayPort 1.4 at HBR3 the question does not arise. If HDMI is how a particular source will connect, tell us what it is and we will check.

Thunderbolt 4 in and out, at 140 W. One cable to the laptop carries 5K2K video, 140 W of charging, 2.5-gigabit Ethernet and seven downstream ports. The Thunderbolt 4 output chains a further display or device, and Lenovo's datasheet states up to two displays in a chain. A Thunderbolt cable is supplied — keep it with the monitor, because nothing generic will substitute.

Power and desk planning. 41 W typical, 300 W maximum with 140 W leaving for the laptop, and a TEC of 127 kWh with an F-class EU energy label. At 947 mm wide and 13.5 kg this also wants a deep, solid desk. If a tender sets an energy-class floor, check it against the F class before specifying.

No pivot, and no 3.5 mm jack. Lenovo publishes tilt, swivel and 155 mm of lift; portrait would be meaningless on a 21:9 panel. There are 5 W x 2 speakers but no headphone socket — headsets connect to the laptop.

In the box, per Lenovo PSREF:

• Monitor with stand
• 1 x DisplayPort 1.4 cable (1.8 m)
• 1 x Thunderbolt cable (1.5 m, 40 Gbps)
• 1 x USB-A to USB-B Gen 1 cable (1.8 m)
• 1 x power cable (1.8 m)
• Factory calibration report
• Quick setup guide

Keep the Thunderbolt cable with the monitor. No HDMI cable is supplied — and if you intend to use HDMI at 5120 x 2160 at 120 Hz, you will need an HDMI 2.1 FRL-capable cable and source. Ask us and we will supply the right one.

ThinkVision P-Series Ordering Information

• Lenovo PSREF specification sheet — ThinkVision P40WD-40 (PDF)
• Lenovo ThinkVision P40WD-40 product datasheet (PDF)

PSREF is Lenovo's own Product Specifications Reference and is the source for every figure on this page unless the table says otherwise. PSREF publishes its spec sheets per model rather than per part number, so this SKU does not appear inside the PDF itself; a per-part-number detail page also exists at psref.lenovo.com and will render in a normal browser if you need this exact configuration confirmed before ordering. Ask us and we will pull it for you.

What can I actually fit on a 5K2K screen?

Two application windows side by side at genuinely usable widths, with no bezel between them — 5120 x 2160 is two 2560-wide halves. A video timeline with panels either side; a design canvas with tool palettes; four or six monitoring windows in a grid. Against a 3440 x 1440 ultrawide you gain about 50% more pixels in each direction, and at 140 dpi it stays sharp.

Do I need Thunderbolt to use it?

No — a USB-C laptop with DisplayPort Alt Mode will drive it and charge from it. A Thunderbolt 4 host gives you the guaranteed 40 Gbps and the chaining topology. At 5120 x 2160 the bandwidth headroom is worth having, so if you are buying laptops alongside the monitor, a Thunderbolt machine is the better pairing. Tell us the model and we will check.

Why does the HDMI port matter here?

Because this model uses HDMI 2.1 FRL, not the TMDS signalling used elsewhere in the range. FRL is what carries 5120 x 2160 at 120 Hz. A source or cable limited to TMDS will not reach that mode. Over Thunderbolt 4 or DisplayPort 1.4 HBR3 it is not an issue. Tell us what will connect over HDMI and we will confirm it works.

Will it charge a mobile workstation?

At 140 W over USB Power Delivery 3.1, very probably — that tier covers machines shipping with a 135 W adapter. If yours is rated 170 W or more, keep the adapter and use the Thunderbolt connection for video, network and data.

Does it rotate, and does it have a headphone socket?

Neither. Lenovo publishes no pivot for this model, which is correct for a 21:9 panel, and no 3.5 mm jack. It does have 5 W x 2 built-in speakers — the strongest in this range — and headsets connect to the laptop.

What does "factory calibrated" actually mean here?

It means Lenovo calibrated this panel on the production line, measured the result and put a printed report in the box — so the monitor is accurate out of the carton without you buying a colorimeter. What it does not mean is hardware calibration: Lenovo publishes no hardware-calibration support for any ThinkVision P-series model, so you cannot write a new calibration into the monitor's own lookup table later. For most design, marketing and video-review work the factory calibration is what matters; for a print house that recalibrates monthly, it is worth a conversation before you order.

What warranty applies in Singapore?

Lenovo PSREF states a 3-year limited warranty as the base warranty for this model, and every unit SourceIT sells comes with local Singapore warranty support and a GST invoice.
