Seatronx released the P4K Marine Display Series in September 2026: four 4K UHD touch screen models in 24, 27, 32 and 43 inch sizes. If you’re shortlisting a marine touch screen monitor for a bridge, navigation or control console, size is the easy choice. The harder part is the set of specs that differ by model: brightness, contrast, typical power, inputs, mounting and weight. Those, plus the papers for the exact model, are what to confirm with Seatronx before you order.
A display ordered by screen size alone can arrive and not fit the console cut-out, the vessel’s DC supply, the source’s video outputs or the approval the vessel needs. That gets found at fitting or survey instead of before the order. Each of those items can be checked on paper first.
What the P4K Series Is
The P4K Series sits in Seatronx’s Marine Displays range alongside other display families, and you’ll find it on Seatronx’s marine displays page.
Seatronx’s P4K Series comes in 24, 27, 32 and 43 inch sizes, each with 4K UHD resolution (3840 x 2160), a projected capacitive multi-touch screen, fanless cooling and an IP66 front panel. Seatronx’s P4K Marine Display Series page lists a datasheet for each of the four models, so every size has its own set of numbers.
Across the series, Seatronx lists a wide 9 to 36 VDC power input and VGA, DVI-D, HDMI and DisplayPort video inputs. The control ports are USB and RS232 remote control. The series is built for bridge, navigation and control applications.
As a general rule, a series page gives a range across the models. The datasheet row for your model is the number to order against.
How the Four P4K Models Compare
Here are the four models side by side, using each datasheet’s own numbers.
| Model | Screen size | Brightness | Contrast | Typical power | Weight | Mounting |
|---|---|---|---|---|---|---|
| P4K-24. | 23.8 inches. | 540 nits. | 1200:1. | 70 W. | 10.5 kg. | VESA mount or panel mount. |
| P4K-27. | 27.0 inches. | 400 nits. | 1000:1. | 55 W. | 16.7 kg. | VESA mount or panel mount. |
| P4K-32. | 32.0 inches. | 350 nits. | 1000:1. | 65 W. | 18.5 kg. | VESA mount or panel mount. |
| P4K-43. | 42.5 inches. | 500 nits. | 4000:1. | 100 W. | 29.5 kg. | VESA mount. |
Seatronx notes on each datasheet that specifications are subject to change without prior notice, so confirm against the datasheet current when you order.
Brightness and Contrast Differ by Model
Read the row for your model, not the series range. Seatronx gives the series ranges of “350 to 540 nits” and “1000:1 to 4000:1,” and marks both as model dependent.
The smallest model lists the highest brightness: 540 nits on the P4K-24. The 32 inch lists the lowest, 350 nits on the P4K-32. The P4K-27 lists 400 nits. The P4K-43 lists 500 nits and the highest contrast of the four, 4000:1. The other three list contrast of 1000:1 to 1200:1.
So brightness doesn’t follow size in this series. If brightness matters for your console, check the number for the exact model you plan to order. For brightness and readability on a marine monitor in general, see Seatronx’s guide to what to look for in a marine monitor.
Power and Inputs: Match the Supply and the Source
All four models list a 9 to 36 V DC input. That’s your first check against the vessel’s supply.
The P4K-27, P4K-32 and P4K-43 datasheets also list “24V DC-in with Isolation (Approval by Certificate).” The P4K-24 datasheet lists a 24V DC power input and a 9~36V DC input range. If your installation needs an isolated input, ask Seatronx which model and configuration carries it, and which certificate goes with it.
Typical power differs too. It’s 70 W for the P4K-24, 55 W for the P4K-27, 65 W for the P4K-32 and 100 W for the P4K-43. In general, a console’s supply and power budget are fixed by the vessel. That means you can check them against the datasheet before the order.
On the video side, Seatronx lists VGA, DVI-D, HDMI and DisplayPort inputs for the series. The datasheets add detail by model:
- P4K-24: one VGA, one DVI-D, one HDMI 1.4 and one HDMI 2.0 input, plus DisplayPort.
- P4K-32 and P4K-43: one VGA, one DVI-D and two HDMI 2.0 inputs, plus DisplayPort.
- P4K-27: one VGA and one DVI-D input are listed. Ask Seatronx to confirm its HDMI and DisplayPort inputs.
The P4K-27, P4K-32 and P4K-43 datasheets list a USB port for the touch screen, and the P4K-24 datasheet lists one USB Type A port. All four list an RS232 port for remote control.
Before you order, confirm that your source drives 3840 x 2160 over the input you plan to use. As a general rule, the source’s video output is fixed by the console. So it can be checked against the model’s input list ahead of time. Whether your bridge needs 4K at all is a separate decision, and Seatronx’s guide to marine display resolution covers it.
Mounting, Cut-Out and Weight
Seatronx lists VESA mount or panel mount for the series, model dependent. Here’s how that splits:
- P4K-24: VESA mount or panel mount. Confirm its panel cut-out with Seatronx.
- P4K-27: VESA mount or panel mount, with a panel cut-out of 655 x 430 mm.
- P4K-32: VESA mount or panel mount, with a panel cut-out of 770 x 500 mm.
- P4K-43: VESA mount.
Outline size and depth decide whether the unit fits the space in and behind the console. In mm, the P4K-27 measures 679.2 x 450 x 69, the P4K-32 795 x 524 x 75.5 and the P4K-43 1028.8 x 617 x 48. The P4K-24 lists a height of 415 mm and a depth of 73.8 mm; confirm its width with Seatronx along with the cut-out. Weights are 10.5 kg for the P4K-24, 16.7 kg for the P4K-27, 18.5 kg for the P4K-32 and 29.5 kg for the P4K-43.
A cut-out is fixed by the console. As a general rule, measure it and compare it with the datasheet before you order, not at fitting. For a VESA mount, confirm the VESA pattern with Seatronx and check your arm or bracket against the model’s weight.
Every model lists an IP66 front panel. The P4K-24 datasheet also gives a rear rating, IP54 rear. If the rear of the unit will be exposed, ask Seatronx for the rear rating of the model you choose.
Approvals and Papers to Request
Seatronx lists IEC 60945 4th Edition, DNV-CG-0339 and IACS E10 for the series. The datasheets also list CE and FCC.
IEC 60945 is the International Electrotechnical Commission’s standard for maritime navigation and radiocommunication equipment. It sets minimum performance requirements, test methods and required test results for shipborne radio and navigational equipment and, for EMC only, other bridge-mounted equipment.
A certificate or test report belongs to a model and a configuration. Options can change what it covers. So ask Seatronx for the test report or certificate for the exact model and configuration you’re ordering. Ask too whether it covers the options you plan to add, such as AR glass, AG film or ECDIS color calibration.
ECDIS gets its own check. The P4K-27, P4K-32 and P4K-43 datasheets list OSD keys for quick changes between ECDIS day, dusk and night modes. They also list an optional color calibration for ECDIS compliance. The P4K-24 datasheet lists a dimming knob and front-panel OSD controls. If the screen will show ECDIS, ask whether the unit you’re ordering has the calibration, and check what the vessel requires.
The environment numbers match on every model: operating temperature of -15 to 55 degrees C, shock of 15G for 11 ms and vibration of 0.7g to DNV-CG-0339 Class A.
Which P4K Size to Shortlist
Size is where you start. The datasheet numbers narrow it down:
- Choose the P4K-24 if console space or weight is the limit. It’s the smallest and lightest of the four, at 23.8 inches and 10.5 kg, and lists the highest brightness, 540 nits.
- Choose the P4K-27 or P4K-32 for a panel-mounted mid-size screen. Their cut-outs are 655 x 430 mm and 770 x 500 mm, with 400 and 350 nits. Both list the ECDIS day, dusk and night mode keys.
- Choose the P4K-43 if the console takes the largest screen on a VESA mount. It lists 29.5 kg, a 48 mm depth, 500 nits, 4000:1 contrast and 100 W typical power.
Whichever marine touch screen monitor you shortlist, order against its own row in the table.
Where the P4K Series Asks More of You
A 4K marine touch screen monitor asks more of the system around it. The source and the cable have to match the input you’ll use. The larger models weigh more. The P4K-43 lists VESA mounting only, so a console built around a flush panel cut-out is a question for Seatronx on that model. The P4K-32 lists the lowest brightness of the four. And some items appear on one datasheet but not another, such as the rear IP rating and the P4K-27’s HDMI count. Each of those gaps is a question to put to Seatronx before the purchase order goes out.
Frequently Asked Questions
What sizes does the P4K Series come in?
The P4K Series comes in four sizes: 24, 27, 32 and 43 inch, named P4K-24, P4K-27, P4K-32 and P4K-43. The datasheets list the panels as 23.8, 27.0, 32.0 and 42.5 inches. Every model has 4K UHD resolution of 3840 x 2160. Brightness, contrast, power, weight and mounting differ by model.
What power input does the P4K Series accept?
All four models list a 9 to 36 V DC input. The P4K-27, P4K-32 and P4K-43 datasheets also list a 24V DC input with isolation, approval by certificate. Typical power runs from 55 W on the P4K-27 to 100 W on the P4K-43. Check the row for your model against the vessel’s supply.
Does the P4K Series have a touch screen?
Yes. Every P4K model has a projected capacitive multi-touch screen. The P4K-27, P4K-32 and P4K-43 datasheets list a USB port for it, and the P4K-24 datasheet lists one USB Type A port. AR glass is listed as an option on the P4K-24, P4K-27 and P4K-32, and AG film on the P4K-27 and P4K-32. If you plan to order a glass option, ask Seatronx whether the certificate you need covers it.
Where can I find the datasheet for each P4K model?
The P4K Series page lists a datasheet for each of the four models: P4K-24, P4K-27, P4K-32 and P4K-43. Each datasheet notes that specifications are subject to change without prior notice, so check the one current when you order. For customized or optional I/O, the datasheets say to contact the Seatronx sales team.
Before You Order a Marine Touch Screen Monitor From Seatronx
Put these on one sheet before the purchase order goes out:
- The model and size, read from that model’s datasheet row.
- The console cut-out, or the VESA pattern if the unit goes on an arm or bracket.
- The supply voltage, and whether an isolated input matters.
- The source and the input it will use at 3840 x 2160.
- The approvals and certificates the vessel needs, for the exact model and options.
- The options, such as AR glass or ECDIS color calibration, plus the ECDIS day, dusk and night keys if the screen will show ECDIS.
With that sheet filled in, tell Seatronx which console, supply voltage and approvals you need.
