A 32-inch monitor may look perfectly suitable on an endoscopy cart, but that doesn’t necessarily mean it is compatible with the monitor arm. Checking a few details before placing an order can help avoid installation problems after delivery.

When selecting a monitor arm for an endoscopy cart, you need to check the monitor’s actual mounting weight, mounting hole pattern, required reach, and intended position on the cart. Screen size alone isn’t enough.

If you plan to install two monitors, you also need to assess whether the cart’s supporting structure can accommodate both monitor arms.

PKN MFG currently offers monitor arm configurations that can support compatible 27–32 inch 4K displays, with a maximum monitor load capacity of 15 kg, depending on the selected configuration and installation requirements.

We have supplied thousands of monitor arm sets together with our endoscopy carts.

These specifications are useful, but they are only a starting point.

Before confirming a monitor arm, we still need to know which monitor the customer plans to use and where they want the screen positioned. Mounting the same monitor close to the cart’s vertical column is different from extending it to the side of the cart. Each arrangement places different demands on the supporting structure.

These differences are not always obvious from a product photograph.

Is Knowing the Monitor Size Enough to Choose an Arm?

Screen size gives us a general idea of how much space a monitor occupies. However, it doesn’t tell us how heavy the monitor is, how it attaches at the back, or how far it needs to move.

When choosing a monitor arm, the term “4K” can also be distracting. It describes the image resolution, not how the monitor connects to the cart.

The most practical starting point is the exact monitor model.

If the model hasn’t been decided yet, customers can send us the specifications of the monitors they are considering. We can then review the mounting requirements before they make a purchase.

Check the Actual Mounting Weight

When checking a monitor’s specifications, pay attention to whether the stated weight includes its desktop stand.

If the stand will be removed before attaching the monitor to an arm, the weight supported by the arm may differ from the monitor’s listed total weight.

On the other hand, if an adapter plate or other accessories are required, their additional weight must also be considered.

For a monitor arm configuration rated for a maximum monitor load of 15 kg, the actual installation still needs to be reviewed.

A monitor weighing less than 15 kg is not automatically suitable. Its mounting pattern and intended operating position must also be confirmed.

Customers don’t need to prepare complicated technical documents. The following information is usually enough for us to begin reviewing the installation.

Information Required	What to Check
Monitor brand and model	Provide the exact model, rather than simply stating “32-inch medical monitor.”
Monitor weight	Confirm the weight based on the actual mounting arrangement.
Rear mounting details	Include the mounting hole spacing, mounting area, and whether an adapter plate is needed.
Intended monitor position	Will the screen be positioned in front of the column, to the side of the cart, or elsewhere?
Number of monitors	Will the cart carry one monitor or two?

Will the Mounting Plate Fit the Back of the Monitor?

The mounting plate is a relatively small component of an endoscopy cart, but if it doesn’t fit, the monitor may not be installed properly.

Our mounting plates can accommodate different monitor mounting hole patterns. However, the appropriate plate still needs to be selected according to the actual monitor.

Supporting different monitors doesn’t mean every model can be installed without checking its specifications.

A photograph of the back of the monitor can be very helpful.

It shows more than just the distance between the mounting holes. It can also reveal whether the mounting area is recessed and how the monitor’s connection ports are positioned relative to the mounting plate.

The mounting screws must also be selected according to the monitor manufacturer’s installation instructions.

Even if the mounting holes align correctly, it doesn’t mean that screws of any length can be used.

Leave Enough Space for Connectors and Cables

Sometimes a mounting plate fits the monitor’s mounting holes perfectly, but the nearby cable connectors are difficult to access.

If the monitor’s rear ports are close to the mounting area, this should be checked before installation.

It’s also important to consider what happens after the cables are connected.

When the monitor arm is folded back, the cables may appear neatly arranged. But when the monitor is extended outward, those same cables may become stretched or pulled tight.

During installation, the required movement range should be checked with the cables connected, leaving enough slack for normal adjustment.

The cables should not become the limiting factor in how far the monitor arm can move.

How to Choose Between Two Monitor Arm Designs

We currently offer two existing monitor arm designs.

When comparing them, the main consideration is whether each arm can position the monitor where it needs to be on the endoscopy cart.

First, decide where the screen needs to be positioned. Then consider how the monitor arm should be installed.

Will the monitor mainly remain in the center of the cart, or does it need to extend to one side?

Will the operator frequently adjust the screen position, or will it stay in roughly the same position most of the time?

Once these questions are answered, choosing the appropriate arm becomes much easier.

An arm with more visible joints is not necessarily the better choice for every application.

Consider the Equipment Around the Monitor

As monitor size increases, the amount of space occupied above the cart also increases.

Even if a larger monitor can be mounted successfully, its edges may come close to endoscope holders, a second monitor, or other equipment installed nearby.

For this reason, the overall layout should be evaluated together with the accessories.

A photograph of an empty cart may not show how these components will interact once everything is installed.

The monitor’s position while the cart is being moved is another important consideration.

A screen extended to the side of the cart occupies a different amount of space compared with one folded back toward the vertical column.

Before confirming the layout, both the working position and the transport or storage position should be considered.

During initial discussions, a marked-up photograph can often explain the customer’s requirements more clearly than a lengthy description.

For example, drawing an arrow on a photograph to indicate “the screen needs to reach this position” is usually more useful than simply asking for a more flexible monitor arm.

Can an Endoscopy Cart Support Two Monitor Arms?

All our endoscopy cart models can be configured with dual monitor arms according to customer requirements.

Ideally, this should be confirmed before production so that the mounting arrangement and overall cart layout can be evaluated together.

Adding a second monitor arm isn’t simply a matter of finding another place to attach it.

Two monitors may need to move within the same area, or they may need to face different directions.

Their cables must also move with the screens without becoming tangled around the other monitor arm.

Even Identical Screen Sizes Need Separate Checks

Two 32-inch monitors don’t necessarily have the same weight or use the same mounting arrangement.

The specifications of each monitor should be checked individually.

A maximum monitor load capacity of 15 kg also cannot simply be multiplied by two to assume that the entire cart can safely support a dual-monitor configuration.

The monitor arms, mounting connections, vertical columns, and overall equipment layout must all be evaluated together.

If customers plan to add a second monitor in the future, it’s best to mention this when ordering the cart for the first time.

This allows us to assess what needs to be prepared in advance and which additional components may be required later.

Having the original cart configuration available makes it easier to review a future upgrade than trying to select a separate monitor arm after the cart has already been delivered.

What Should You Check Before Confirming the Configuration?

For overseas buyers, photographs and videos can help clarify details that may not be fully explained in a specification sheet.

An overall photograph should show the position of the monitor arm relative to the vertical column, shelves, and accessories.

Close-up photographs should show the mounting plate and its connection points.

If the agreed monitor or suitable testing conditions are available, video demonstrations can also be used to show positioning adjustments and support checks.

We support live video inspections and can also record inspection videos for customers.

If customers tell us in advance which positions or details they want to see, the inspection can be more focused.

It’s also important to distinguish between load testing and compatibility with a specific monitor.

Our monitor arm load tests are carried out using test weights.

However, a load test alone cannot confirm whether the rear connection ports of a particular monitor will interfere with the mounting plate.

That still needs to be checked against the monitor’s dimensions, mounting structure, and installation documentation.

If you would like to discuss a suitable configuration, you can send us the monitor model, a photograph of its rear mounting area, your preferred screen position, and whether you need a single- or dual-monitor setup.

Conclusion

Choosing a monitor arm should start with the actual monitor and how it will be used.

Confirming the mounting weight, connection details, adjustment range, and overall cart layout before production can help reduce installation problems and unnecessary adjustments after delivery.
