Buyer’s Guide
LED Wall Screen for Meeting Rooms: Everything You Need to Know Before You Buy
A plain-English guide to choosing the right LED wall screen for your meeting room or video conferencing space, including an honest comparison of SMD, GOB, and MIP technology.
Most meeting rooms were designed around projectors or large TV screens. Both options have served their purpose, but they have real limitations that become obvious the moment you walk into a modern, well-lit boardroom trying to show a presentation.
Projectors wash out in bright rooms. Large TVs have visible bezels and struggle to scale cleanly to the wall sizes a proper boardroom or training room demands. LED wall screens fix both problems, and they have become the standard in corporate environments that take their meetings seriously.
The challenge is that walking into a conversation about LED walls for the first time can feel like stepping into a foreign language. Pixel pitch. SMD. GOB. MIP. Nits. Fine pitch. The terminology multiplies fast, and suppliers do not always slow down to explain it.
This guide does the opposite. It starts from scratch, covers everything you need to make a confident decision, and gives you a clear comparison of the three LED technologies you will encounter most often when shopping for a meeting room display.
Why LED walls are replacing projectors and large TVs in meeting rooms
The practical case for LED wall screens in corporate spaces comes down to three things: brightness, scale, and reliability.
A projector works by throwing light at a surface and hoping the room is dark enough for the image to look good. The moment someone opens the blinds or turns on the overhead lights, the image fades. LED displays generate their own light directly from the screen surface, so they stay sharp and vivid regardless of how bright the room is. Brightness is measured in nits, and a quality LED wall typically delivers between 800 and 5,000 nits. That is bright enough to look excellent in any normal office environment.
Scale is the other major factor. LED wall screens are built from individual panels joined together, which means you can build a display to almost any size with no visible seams between panels. A 4-metre wide display with no border, no bezel, no frame. A TV cannot do that. A projector can approximate it, but not with the same sharpness or reliability.
Then there is lifespan. Most LED wall screens are rated for 50,000 to 100,000 hours of use. At 8 hours a day, that is well over 17 years before the display reaches half its original brightness. There are no bulbs to replace. No lamp hours counting down. And because the screen is modular, individual panels can be swapped out if needed without touching the rest of the wall.
For video conferencing in particular, image quality matters more than it used to. When your team is presenting to a client over Zoom or Microsoft Teams, the content on screen behind them reflects on your organisation. A crisp, professional meeting room display signals that you take communication seriously.
What an LED wall screen actually is
An LED wall screen is a large display surface made up of individual LED modules fitted together to form a seamless image. Each module contains thousands of tiny LED lights arranged in a grid. The LEDs switch on and off and change colour to create the picture, pixel by pixel.
Unlike a TV, there is no glass panel over the screen surface. Unlike a projector, there is no separate projection unit or screen material. The screen itself is the source of light. This is what makes LED displays so much brighter than projection and so much more scalable than any panel display.
The modules are mounted onto a frame structure, which can be wall-mounted, ceiling-hung, or built as a freestanding unit. A qualified AV integrator handles the structural side, the cabling, the control system, and the calibration. Once installed, the day-to-day experience for your team is simply: turn it on, connect your device, and the meeting starts.
Key term
An LED wall screen for a meeting room connects to your video conferencing system, laptop, or presentation device exactly like any other display. The only meaningful difference in day-to-day use is the size and image quality.
What to think about before you buy
Before you look at specific technologies or pixel specifications, get clear on the basics. These four factors shape everything else.
Room size and screen size
A common starting point is that the screen width should be roughly one third of the room length. For a 9-metre conference room, a 3-metre wide screen works well as a baseline. Your AV integrator should refine this based on your actual seating layout, content type, and how the room is used. A training room with 30 people seated theatre-style needs a different calculation to a boardroom with 12 people around a table.

Viewing distance
The distance between your screen and the nearest viewer determines how fine the pixel pitch needs to be. Closer viewers need a smaller pixel pitch to see a sharp image. Viewers further away can work with a larger pixel pitch without losing clarity. This matters for budget because finer pitch costs more.
Room lighting
Consider how bright your meeting room is during normal use. A standard indoor LED display needs a minimum brightness of around 600 cd/m² (candelas per square metre, also called nits) to look good under normal office lighting. If your meeting room has large windows or faces direct sunlight, you need a panel rated at 3,000 cd/m² or above — otherwise the image will look washed out in the middle of the day. Rooms with blackout blinds or controlled lighting can work well with lower-brightness panels, which tend to be easier on the eyes during long sessions.
Budget
LED wall screens represent a wider range of price points than most buyers expect. A standard SMD display for a mid-sized meeting room sits at a very different price to a premium MIP panel for an executive boardroom. Be honest about what you actually need before you look at specifications, because the technology tiers align reasonably well to use case and budget.
Pixel pitch and viewing distance explained
Pixel pitch is the most important technical number you will encounter when comparing LED wall screens. It refers to the distance, measured in millimetres, between the centre of one LED cluster and the centre of the next. It is written as a P-value. P1.5 means 1.5 mm between pixels. P4 means 4 mm between pixels.
The smaller the number, the more pixels packed into the same area, and the sharper the image at close range. The larger the number, the fewer pixels per square metre, and the lower the resolution. A large pixel pitch is not inherently bad. It just means the display needs more distance before the individual pixels blend into a smooth image.
Think of it like a printed poster. Stand close to a large billboard and you can see the individual ink dots. Step back far enough and the image looks sharp. LED displays work the same way, except the pixel pitch determines how far back you need to stand.
A practical shortcut used across the industry: the P-number roughly matches the minimum comfortable viewing distance in metres. P2 starts to look sharp from 2 metres. P3 from 3 metres. P4 from 4 metres. It is not a perfect formula, but it gives you an immediate sense of whether a quoted pitch suits your room before you look at anything else. Finer pitches also pack significantly more pixels into the same area — a P3 panel has 111,111 pixels per square metre, while a P5 has 40,000 and a P10 drops to 10,000. That difference is visible when viewers are close.
Zoomed-in view of the same physical area of LED panel. Fine pitch (P1.5) packs over 7× more pixels into that space — producing a sharp image when viewers are close. Coarse pitch (P4) suits larger rooms where viewers sit further back.
| Pixel Pitch | Minimum Viewing Distance | Typical Meeting Room Use |
|---|---|---|
| P0.9 to P1.2 | 1 to 2 metres | Small executive rooms, close-up presentation walls |
| P1.5 to P1.9 | 2 to 3 metres | Standard meeting rooms and boardrooms (most common choice) |
| P2.0 to P2.5 | 3 to 4 metres | Larger boardrooms, training rooms, seminar spaces |
| P2.5 to P4 | 4 to 6+ metres | Auditoriums, large training halls, town halls |
Practical tip
Measure the distance from the screen to the nearest seat in your room. That number, in metres, is your benchmark. A P1.5 display suits a viewer 2 to 3 metres away. If your nearest seat is 4 metres from the screen, a P2.0 or P2.5 will look just as sharp at a lower cost.
The three technologies: SMD, GOB, and MIP
Once you have a sense of room size, viewing distance, and budget, the next decision is which LED technology to use. Three options come up most often in corporate meeting room installations: SMD, GOB, and MIP. They differ in how the LED chips are packaged and protected, which affects image quality, durability, cost, and maintenance.
Here is each one explained in plain terms.
Standard
SMD
Surface-Mounted Device
SMD is the established standard for indoor LED displays. Red, green, and blue LED chips are mounted directly onto a circuit board, with three chips grouped together to form each pixel. It has been the dominant technology in corporate AV for well over a decade.
The LED chips sit exposed on the surface of the module. They are small, precise, and capable of excellent colour accuracy. Because SMD manufacturing is mature and widely understood, parts and repair expertise are readily available.
Cost-effectiveEasy to repairChips exposed
Best for standard meeting rooms
Protected
GOB
Glue on Board
GOB starts with the same SMD technology and adds a layer of clear, optically transparent resin poured over the entire module surface. The resin sets hard, sealing the LED chips inside a protective shell that is resistant to dust, moisture, and physical impact.
Think of it like applying a coat of varnish to timber. The underlying material is the same. The protective layer on top is what changes its durability. The resin is optically clear, so the image quality is not compromised. The surface is also smooth and easy to wipe clean.
Impact resistantDust and moisture proofRepairs more involved
Best for high-traffic and touch areas
Premium
MIP
Micro LED in Package
MIP is the newest of the three. The LED chips themselves are microscopic, each one under 100 microns in size, and they are individually encapsulated inside their own protective housing before being mounted onto the panel. This approach combines ultra-fine pixel density with built-in chip protection.
The result is exceptional image sharpness at very close viewing distances, strong resistance to physical damage, and a longer operational lifespan per chip. MIP panels can achieve pixel pitches below P1.0, which opens up 4K and near-4K resolution on displays that are still practical for a boardroom.

Side-by-side comparison: SMD vs GOB vs MIP
Here is how the three technologies compare across the factors that matter most for a corporate meeting room purchase.
| SMD | GOB | MIP | |
|---|---|---|---|
| What it is | LED chips mounted directly on circuit board | SMD chips sealed under clear protective resin | Microscopic LEDs individually packaged and mounted |
| Typical pixel pitch | P1.2 to P10 | P1.2 to P10 | P0.4 to P1.0 |
| Image quality | Good | Good | Excellent |
| Durability | Moderate | High | Very High |
| Impact resistance | Limited | Strong (resin absorbs impact) | Strong (chip-level encapsulation) |
| Dust and moisture | Moderate protection | Excellent (fully sealed surface) | Excellent (individually sealed chips) |
| Surface cleaning | Careful cleaning required | Smooth surface, easy to wipe | Easy |
| Cost | Most affordable | Mid-range | Premium |
| Repairability | Simple: replace individual modules | More involved: resin must be worked through | Specialist repair required |
| Technology maturity | Established, widely supported | Established, widely supported | Newer, growing rapidly |
| Best for | Standard boardrooms, meeting rooms | High-traffic areas, training rooms, touchable displays | Premium boardrooms, high-end AV installations |
Which technology is right for your meeting room?
The right choice depends on three things: how the room is used, how close viewers sit to the screen, and what budget you are working with. Here is a straightforward way to think about it.
Choose
SMD
Your meeting room is standard, wall-mounted, and not in a high-traffic area. Budget matters and you want a proven, easy-to-maintain display. This covers the majority of Malaysian corporate meeting rooms.
Choose
GOB
Your space is a busy training room, a lobby, a reception area, or any location where the screen might be touched, bumped, or exposed to dust. You want the same image quality as SMD but with a more resilient surface.
Choose
MIP
You want the best possible image quality for an executive boardroom or premium AV installation. Viewing distances are close, content is high-resolution, and budget reflects the importance of the space.
For most standard meeting rooms and boardrooms in Malaysia, SMD at P1.5 to P2.5 is the starting point. It delivers excellent image quality for video conferencing and presentations, is well-supported by local AV integrators, and represents good value for money. GOB is worth considering anywhere there is regular foot traffic past the screen or a risk of accidental contact. MIP is the right choice when image quality is non-negotiable and the room’s purpose justifies the investment.
Video conferencing note
For video conferencing rooms specifically, the LED wall is one part of the picture. The camera, microphone, speaker system, and room acoustics all affect the quality of your calls. A great LED wall screen paired with a poor camera will still produce a poor video conferencing experience. Specify the whole room, not just the display.
Questions to ask your supplier before you commit
A supplier who knows what they are doing should be able to answer these without hesitation. If they cannot, that tells you something useful.
What pixel pitch do you recommend for my room, and why? Ask them to walk you through the viewing distance calculation for your specific space. If they recommend a pitch without asking about your room dimensions, press them on it.
Can I see a demonstration unit running real content? Any reputable AV integrator will have demo units available. Seeing a display running presentation slides and video conferencing content in real light conditions is worth more than any specification sheet.
What does the warranty cover and for how long? LED walls from established suppliers typically carry a 3 to 5 year warranty. Ask specifically what the process is if a panel fails. Who comes, how quickly, and what is covered.
Who handles installation and what does it include? Installation should include the structural mounting, cabling, control system setup, and commissioning of the display. Ask whether training for your team is included.
Is the technology SMD, GOB, or MIP? If the supplier does not use these terms or cannot explain the difference, that is a red flag. These are the standard industry distinctions and any competent AV integrator should be fluent in them.
What is the typical installation timeline? A straightforward meeting room LED wall installation usually takes one to two days once all equipment is on-site. Larger or more complex builds take longer. Get a written timeline.
Fixed installation vs modular rental panels
There are two types of LED display: permanent fixed installations and modular rental-style panels. Fixed installations are built into your space, calibrated, and optimised for that room. Modular panels (common for hotel ballrooms and event stages) are designed to be assembled and disassembled repeatedly. They use different mounting systems, different pixel pitches, and different quality tiers. If you are fitting out a meeting room or boardroom, you want a fixed installation. Make sure your supplier is quoting you accordingly.
Frequently asked questions
What pixel pitch do I need for my meeting room?
For a standard meeting room where viewers sit 2 to 4 metres from the screen, a pixel pitch between P1.5 and P2.5 delivers sharp, clear images at a reasonable cost. Smaller rooms or closer viewing distances need a finer pitch. Larger rooms with viewers sitting further back can work with P2.5 to P4.0 without visible loss of quality.
What size LED wall do I need for a conference room?
A general starting point is that the screen width should be roughly one third of the room length. For a 9-metre room, a 3-metre wide screen works well as a baseline. Your AV integrator should calculate this based on your actual room layout, seating position, and content type. The height of the screen follows from the standard 16:9 aspect ratio used in most presentation and video conferencing content.
How long does an LED wall screen last?
Most LED wall screens are rated for 50,000 to 100,000 hours of use. At 8 hours of daily use, that is well over 17 years before the display reaches half its original brightness. In practice, the modular design means individual panels can be replaced without replacing the entire screen, so a well-maintained LED wall can last significantly longer than that benchmark suggests.
Can I use an LED wall screen for Zoom or Microsoft Teams video conferencing?
Yes. LED wall screens work with all major video conferencing platforms including Zoom, Microsoft Teams, and Google Meet. You connect your conferencing device or laptop to the LED wall just as you would any other display. For best results, pair the LED wall with a quality camera, microphone, and speaker system sized for your room. The display alone does not make a complete meeting room display system.
Is an LED wall screen better than a projector for a meeting room?
For most corporate meeting rooms, yes. LED wall screens produce their own light, so they stay bright and clear even in well-lit rooms. Projectors need a darkened or dimly lit room to look their best, which is rarely practical in a working boardroom. LED walls also require no bulb replacements, have no warm-up time, and last significantly longer. The main trade-off is upfront cost, which is higher for an LED wall, but the lower ongoing maintenance cost closes that gap over time.
What is the difference between SMD, GOB, and MIP LED technology?
SMD is the standard LED technology, widely available and cost-effective. GOB adds a clear protective resin layer over SMD chips, making the display more durable and easier to clean without changing the underlying image quality. MIP uses microscopic LED chips individually packaged before mounting, delivering superior image quality at very fine pixel pitches. SMD suits most standard meeting rooms, GOB suits high-traffic spaces or areas where the screen may be touched, and MIP suits premium boardrooms where image quality is the priority.
How much does an LED wall screen for a meeting room cost in Malaysia?
The cost varies significantly based on screen size, pixel pitch, and technology type. Entry-level SMD installations for a standard meeting room start from the low five-figure range in Ringgit. Premium MIP panels for an executive boardroom can cost considerably more. The best approach is to describe your room and requirements to a qualified AV integrator and request a scoped proposal. A reputable supplier will give you a clear breakdown with no surprises.
