You pick the software, set it up, and then wonder why orders aren’t showing up clearly, or at all. Nine times out of ten, it’s not the software. It’s the physical setup. Wrong display, and your cooks can’t read through the steam. No wired connection, and tickets vanish mid-rush. A cheap mount, and the whole thing is on the floor by Saturday night.
If you’re planning a restaurant tech upgrade, Savorq helps restaurants choose KDS hardware and POS setups that actually survive real kitchen conditions.
At Savorq, this is the part we see people get wrong most often. So here’s a straight breakdown of every KDS hardware requirement, what each spec means, what to look for, and what to avoid.
KDS hardware requirements depend on your chosen software, but most setups need a 10–27-inch display, 4GB+ RAM (8GB for busy kitchens), Android 7+ or Windows 10+, and a stable wired network. High-volume kitchens also need IP54+ rated, fanless units with proper commercial mounting.
What Actually Falls Under “KDS Hardware Requirements“?
Most people assume it’s just a display. It’s not. A full kitchen display system setup involves:
- The display/monitor: the screen on which your kitchen staff reads orders
- The controller: the computer or embedded unit running your KDS software
- Mounts and brackets: how and where the screen sits at each station
- Network equipment: cables, switches, router
- Bump bar: an optional physical controller for interacting without touching the screen
- Printer: optional backup for order tickets or labels
- Soundbar: optional audio alert for new incoming orders
All the pieces are linked to one another. A system is weak when one of its parts is weak.
Display Requirements: Size, Brightness, and Type
This is where most buying decisions happen and where most mistakes get made.
Screen Size
Size depends on who’s reading it and from how far away. A prep cook right next to the fryer doesn’t need a large display. An expeditor managing four stations at once does.
| Station | Screen Size | Reason |
| Prep stations (grill, fry, salad) | 10–15 inches | Close range, tight counter space |
| Expeditor/expo station | 22–24 inches | Reads multiple tickets at a glance |
| Ghost kitchen/cloud kitchen | 15–21 inches | Multiple order streams, compact layout |
| Manager overview screen | 24 inches+ | Full kitchen visibility |
If the size of the screen is too small for your expo person to read a modifier, it’s too small! Those additional steps are quick to accumulate at 200+ covers per night.
Brightness
A regular office monitor runs around 250–300 nits. That’s fine at a desk. Place it in a commercial kitchen under overhead lights, and there won’t be a lot of reading at dinnertime.
If you’re buying for kitchen display screens, these are the times to consider looking for:
- 500 nits: the absolute floor for any commercial kitchen
- 800–1000 nits: where you want to be if your kitchen has heavy overhead lighting or any natural light coming in
The best screens for KDS setups are purpose-built for this. There are no TV sets, and there are no office monitors. Do not replace – it will be replaced twice, and you will end up paying more for it.
Touchscreen or LCD with Bump Bar?
Touchscreen (PCAP): Staff taps directly to mark orders, bump tickets, or flag an item. Fast to learn, fast to use. Most commercial units handle 10 simultaneous touch points, and the good ones respond even with slightly wet fingers or gloves.
LCD with bump bar: The display shows orders only. A separate bump bar, a physical controller with buttons, handles all interaction. It’s more likely to occur at the dirtiest stations, like the frying or butchering station, because the screen can’t be easily accessed.
Both options are correct. Almost all kitchens have touch screens at all of their stations and bump bars at the greasiest ones.
Durability: What Durable Screens for Hot Kitchens Must Have
A commercial kitchen runs hot, greasy, and wet every shift. Any KDS unit in that environment needs specs that match it, not office-grade components dressed up in a box.
IP Rating
If you’re looking for a minimum, it should be IP54. The numbers are the result of the following:
- 5 = fully protected from dust and solid particles
- 4 = protected from water jets hitting from any direction
Some can reach IP65 or IP66, which is a better rating? If the IP rating is less than IP54 for a commercial kitchen, it is a risk to play, and kitchens play the game against you.
Operating Temperature
Standard electronics are rated to about 40°C. Near a commercial fryer or grill? You’re often looking at 55–60°C. Look for KDS units rated to at least 60°C; that number matters much more near cooking equipment than people expect.
Fanless Design
Fans keep electronics cool, but in a kitchen, they also pull grease, steam, and food particles into the unit over time. Fanless designs do not use fans to regulate heat; the casing does. They are quieter in use, keep the interior cleaner for a longer time, and last significantly longer in kitchen use.
Sealed Glass
Zero-bezel or flat-sealed glass means no gap around the screen edge where grease and food collect. Faster to clean, stays sanitary longer, and keeps the display working properly over time.
Controller: Processing Requirements for KDS
The controller is the computer running your KDS software. It may be built into an all-in-one unit or exist as a separate box connected to wall-mounted displays.
| Spec | Minimum | Better |
| Operating System | Android 9 / Windows 10 | Android 11+ / Windows 11 |
| RAM | 3 GB | 4–8 GB |
| Stroage | 32 GB | 64 GB SSD |
| Processor | Basic embedded | Intel IoT embedded (15-year lifecycle) |
Android vs. Windows: Android is cheaper, works with most modern KDS apps, and is straightforward to manage. For enterprise environments or if the point-of-sale system is a Windows-based solution and must offer more integration, Windows is a better choice. Other platforms, such as Fresh KDS, are compatible with just about any iPad and Android tablet that you have.
On RAM: A kitchen pulling orders from dine-in POS, a kiosk, online ordering, and a delivery app all at once needs a controller that keeps up. 4GB handles that load. 2GB starts to struggle at volume, and 8GB is the right call for high-traffic multi-station setups.
Mounts and Brackets for Kitchen Displays
A screen at the wrong height causes neck strain. A screen at the wrong angle causes misread orders. If the screen is not securely mounted, it’s sure to vibrate with each bump on the counter, which is a common gripe – and rightly so.
Mounts and brackets for kitchen displays come in a few configurations:
- Wall mount: fixed, stable, best for permanent stations with no layout changes planned
- Pole/stand mount: freestanding, easy to move if your layout shifts
- Under-shelf bracket: tucks the screen under an existing shelf to keep prep surface clear
- Adjustable arm mount: most flexible option, lets staff tilt and angle as needed per shift
- Ceiling mount: good for open kitchens where wall and counter space is already spoken for
Most commercial KDS screens follow a VESA 100×100mm mounting pattern, so you can pair them with third-party mounts for more flexibility. The point is that the mount itself is commercial, but not a consumer mount, as that would not be designed to withstand vibrations and heat in the kitchen.
Network Setup for KDS: More Important Than Most People Expect
You can spend serious money on the right screens and still end up with a broken KDS if the network isn’t right. The restaurant is a very challenging wireless environment: stainless steel abounds, there are microwaves, refrigeration units, and heavy appliances.
Wired Over Wi-Fi, Every Time
Ethernet is the right call. A KDS going offline for 45 seconds during a dinner rush isn’t a small problem. Orders back up, staff lose visibility, and the whole service flow breaks down. Wire it up, and the problem goes away.
That’s good, but Power over Ethernet (PoE) goes beyond that; one Ethernet cable provides power as well as data to the screen. That means:
- No need for a power outlet at every station
- Cleaner cable runs through the kitchen
- No power bricks cluttering prep areas
- Screens are much easier to reposition later if your layout changes
Network Setup Checklist for KDS
- 1G wired Ethernet to each screen
- Dedicated network switch if you have 4+ screens
- All KDS devices and the KDS server are on the same network (same domain or workgroup)
- Local network operation confirmed, which means that your system will continue to run even when the Internet connection is down. Check with your KDS software provider before going live.
Optional Hardware Worth Thinking About
Your core KDS hardware requirements are covered: screens, controller, mounts, and network. But a few extra pieces can make a real difference in how smoothly your kitchen actually runs day to day.
Bump Bars
Even with touchscreens at most stations, a bump bar makes sense at the greasiest or wettest stations, frying, butchering, and dishwashing-adjacent areas. USB-connected, physical buttons, works with gloves on. Some manufacturers, such as the ones named, produce bump bars that have been specifically designed for use in the kitchen.
Audio Alerts / Soundbar
A loud kitchen misses visual changes on screens constantly. Some commercial KDS units support an integrated soundbar with water-resistant speakers. A new order, as soon as it appears on the screen, is sounded. Staff are aware of this at once, without having to check the display every second. It is helpful to use it where slightly behind the cook.
Backup Printers
Some kitchens have a thermal printer as a backup; if the screen fails, orders will continue to print. Common options that fit in well: Zebra ZD410, Bixolon SRP-S300, Epson TM-M30ii.
KDS Hardware Requirements by Kitchen Type
Not every kitchen runs the same way, so your KDS hardware requirements won’t look the same either. A food truck and a ghost kitchen are two completely different setups, with different order volumes, different station counts, and different space constraints. Here’s a quick breakdown of what actually makes sense for each type:
| Kitchen Type | What You Need |
| Small café or food truck | 10–12″ tablet (iPad or Android), basic mount, Wi-Fi acceptable at low volume |
| Fast casual / QSR | 15–21″ commercial touchscreen, fanless, IP54+, wired Ethernet, bump bar |
| Full-service restaurant | 21–24″ display per station, PoE, separate expeditor screen |
| Ghost/cloud kitchen | Multiple screens, strong wired network, centralized expo view |
| Multi-brand kitchen | Per-brand KDS units plus shared expeditor screen for order completion |
Mistakes That Show Up Later If You Skip Them Now
Purchasing consumer tablets and relying upon them to last. They overheat. Brightness is not sufficiently bright. Their ratings are not for commercial use. You will have to replace them within a year and even end up spending more than what you saved initially.
Going with Wi-Fi because it’s easier to set up. Is comfortable when tested. Causes issues on Fridays and Saturdays.
Skipping POS compatibility checks. Your KDS hardware requirements are partly shaped by what your POS supports. Check compatibility before buying anything; this is the mistake that costs the most to fix after the fact.
Selection of screen size by cost and not by location. A small screen is only suitable for the viewing distance of that station if it is suitable. Don’t order until you walk your stations.
Key Takeaways
- The KDS equipment specifications include the following: Display, Controller, Mount, Network equipment, Bump Bar, and optional accessories.
- For kitchen display screens, target 500+ nits and IP54+ as your floor, don’t go below either
- Controller minimum: Android 9 or Windows 10, 4GB RAM, 64GB storage
- Mounts and brackets for kitchen displays should follow VESA 100×100mm, always go commercial-grade
- Network setup for KDS should be wired Ethernet, ideally PoE. Wi-Fi in a commercial kitchen is a liability
- For hot kitchens, you will require screens that can be cooled without the need for fans, are sealed, and can withstand temperatures of up to 60°C
- It is important to check the compatibility of the Point of Sale system before buying any equipment
Final Thoughts
Getting your KDS hardware requirements right doesn’t require a deep technical background; it needs a clear plan before anything gets ordered. At Savorq, the first thing we tell any restaurant owner is this: walk your kitchen, map your stations, and check your POS compatibility before you look at a single product page.
The physical setup is what your staff works with every single shift. When it’s right, nobody notices. When it’s wrong, everyone does.

FAQs
What are the basic KDS hardware requirements for a commercial kitchen?
The core KDS hardware requirements include a commercial-grade display (500+ nits, IP54+), a controller with at least 4GB RAM, a proper mount, and a wired Ethernet connection. Here’s what each of those means in practice.
Do KDS screens need to be touchscreen?
No. A standard LCD with a bump bar is good and is often the preferred option at stations where employees have gloves or have wet hands. Touchscreens are faster for most setups, but they’re not a hard requirement.
What IP rating should I look for in a kitchen display?
IP54 is the minimum. The “5” covers full dust protection; the “4” covers water jets from any direction. For stations close to fryers, sinks, or dishwashing areas, IP65 or IP66 gives better protection.
Can I use a regular TV or iPad as a KDS screen?
The iPad or Android tablet can do the trick, particularly for smaller kitchens or for a beginner. Most office or home monitors are not rated to withstand high temperatures, moisture, and grease in a commercial kitchen and will fail more quickly; they are not as bright as most kitchen lighting. For any permanent setup, budget for purpose-built equipment.
Does a KDS need internet to work?
It needs a local network connection between the KDS screens and the KDS server or POS. Most systems are designed to keep running even when the internet drops, but confirm this with your software provider before you go live. It’s a question worth asking.
What’s the difference between a prep KDS and an expo KDS?
A prep KDS shows only the items relevant to one station; the grill cook sees grill items, the fry cook sees fry items. An expo KDS provides complete visibility across all stations and all tickets, and is used by the expeditor coordinating the overall order flow, to ensure that complete orders are sent out together.
How many KDS screens does a restaurant need?
One screen per kitchen station is the baseline. A burger restaurant with four stations, grill, fry, assembly, and expo, needs four screens. If your kitchen manager requires complete visibility of your kitchen, add a manager/summary screen.
What happens if the KDS screen goes down mid-service?
If you have a backup printer connected, orders will continue printing on paper as a fallback. This is why some kitchens keep a thermal printer running alongside their KDS. It also minimizes the risk of this occurring in the first place if there is a local network (that is, not relying on the internet).
