A POS screen is suitable for a bright service point only if staff can read the information they need and complete routine tasks under the light and viewing angles they will actually face. A strong brightness specification helps narrow the choices, but it cannot tell you how sunlight, reflections and the screen layout will combine at your counter.
Before buying, compare the same device at the indoor counter and at the brightest outdoor or window-facing position where it might be used. Ask staff to read and operate it in a simulation, then record what they saw, where errors occurred and whether a practical fix exists.
Set visibility requirements for each service point
Start with the places where the screen will be used, not just the device on the quote. A terminal beside a front window may be clear at breakfast and washed out in the afternoon. A handheld may move between a shaded dining room and a sunny patio. A kiosk may face a different direction from the counter and be read by guests of different heights.
List the task, location and person who needs to read the display. For a cashier, that might mean finding a modifier and checking the order total. For a patio server, it might mean reading item names and confirming a table assignment while standing. For a guest-facing display, it could mean reading the total without leaning across the counter.
Pick the conditions that matter most: direct sun, reflected light from windows or polished surfaces, and the brightest periods of service. Also note any lighting changes expected when doors or blinds are open. If the screen will be shared, include staff with different heights and normal working positions.
Set an acceptance standard before looking at results. For example, staff should be able to read item names, modifiers and totals from their usual position without shading the screen with a hand. They should be able to complete the selected practice tasks without a visibility-related mistake. Decide separately how much extra time, if any, is acceptable when moving from indoor light to outdoor glare.
The owner or operations lead should approve the final decision, with a shift lead responsible for arranging the checks and recording results. Involve the people who will use the screen during service. Make this decision before signing for hardware when possible; changing the screen position after installation may affect counter space, cables and staff movement.
Compare brightness, reflection and viewing angle
Ask each vendor for the exact screen model and configuration in the quote. Request its brightness information, available adjustment settings and any guidance for use in direct sunlight. A specification is useful for comparing candidates, but a higher number alone does not establish that a screen will be readable at your service point. Surface reflections, screen content and the angle of the sun also matter.
Check whether staff can adjust brightness quickly and whether the selected setting stays in place as the device moves between indoor and outdoor areas. Ask how automatic adjustment, if offered on the quoted device, behaves when the screen moves from shade into sun. Confirm whether the setting can be controlled by staff or must be changed by a manager.
Viewing angle matters because people rarely stand squarely in front of a restaurant screen all shift. Look from the normal working position, then from the side and from the height of a shorter or taller user. On a handheld, vary the angle at which a server would hold it while carrying other items. On a fixed terminal, check whether its stand can be positioned without blocking a work surface or exposing guest information.
Read the actual screens used in the workflow, not just a bright home screen. Small modifier labels, pale text, icons and totals can be harder to distinguish than large menu buttons. Ask to see the relevant order-entry and confirmation screens on the exact device. If a kiosk, handheld or guest display is also in scope, check it separately rather than assuming it will look the same.
Fleksa's restaurant hardware range includes counter terminals, handhelds, kitchen displays and kiosks. Ask which specific device is being offered and whether it works with your intended setup. Device, operating system, printer connection and processor compatibility can affect that answer; an existing tablet or terminal is not automatically reusable.
Run the same-screen visibility check
Use one screen and the same practice tasks at the indoor counter and at the outdoor or glare-prone location. If the restaurant does not yet have the device, ask the vendor to bring the quoted model and demonstrate the relevant screens at the intended positions. Try to schedule the outdoor check when the problem light is likely to occur. If that is not possible, mark that condition unknown and arrange a follow-up.
Use a simulation or training setup that cannot take a real payment, send a guest message or dispatch a courier. Confirm those safeguards before starting. A practice order is enough to observe the screen; it does not need to reach a kitchen or guest. A live service pilot, if you later choose one, is a separate step with real operational consequences and needs its own controls.
Give each participant the same short task list. Include reading an item and modifier, selecting them, reviewing the order and locating the total. Tell staff what outcome to expect, but do not point out the buttons during the check. Have the shift lead observe without correcting them immediately.
- Set the baseline. At the indoor counter, record the screen position, brightness setting, task and expected result. Note whether the participant can read each label from their normal position and complete the practice order correctly.
- Move to the glare position. Use the same device, screen layout and tasks outdoors or beside the bright window. Record the time, weather, direction of the light and whether the screen is in sun or shade.
- Observe and compare. Note misread labels, wrong selections, repeated attempts and pauses to change position. Ask the participant which information was difficult to read. Record whether the problem was visibility or a separate input issue, such as touching the wrong button despite reading it clearly.
- Try a practical adjustment. Change brightness or reposition the screen, then repeat the affected task. Record the adjustment and whether it would be workable during a busy shift. Do not count a fix that requires a staff member to hold a shade over the display throughout service as a normal operating position.
A timer can help identify a large slowdown, but it should not be the only measure. A fast entry with the wrong modifier is not a pass. Equally, a participant who takes longer because they are learning the layout may not have a visibility problem. Record the cause where you can and leave it open where you cannot.
For a restaurant POS, also check the moments when staff must verify an order with a guest. If the employee can read the screen but the guest cannot see the confirmation from their side, record that as a separate issue for the guest-facing position.
Document the decision and handle exceptions
Use a short decision record for each device and position. The following is a hypothetical example for one handheld, using a standard that requires readable labels and a correct practice order without hand-shading. The indoor and patio observations are separate checks on the same screen; they do not establish how any particular product will perform.
| Condition | Result | Observation | Follow-up and owner |
|---|---|---|---|
| Indoor counter | Pass | Labels and total readable; practice order correct. | Shift lead records setting and position. |
| Sunny patio | Fail | Modifier label hard to read; participant selected the wrong modifier. | Vendor demonstrates a workable screen position; shift lead repeats task. |
| Patio under shade | Unknown | Shade was unavailable during the check. | Operations lead schedules a check before rollout. |
The table keeps a pass from being applied to every location. In this example, the handheld should not be approved for the sunny patio on the strength of the indoor result. A retest after repositioning could support a different decision, but only if staff can use that position during normal service and meet the original standard.
Consider the trade-offs before accepting a workaround. Higher brightness may affect handheld battery life; ask the vendor how to assess it on the quoted device and check whether the device can last through the intended shift. Moving a terminal away from glare may reduce usable counter space or change how cables reach it. A shade or screen cover may help, but check whether it obstructs staff or guest viewing and whether it stays effective as the sun moves.
For an exception, write down who approves it, the affected location, the temporary procedure and when the team will retest. For example, an operations lead might restrict a handheld to shaded service until a suitable outdoor check is complete. If the restaurant needs it in direct sun immediately and no workable position has passed, choose another arrangement or postpone that use. Do not turn an unknown into a pass because the purchase date is close.
Keep the visibility record with the broader device and workflow decision. Your restaurant management software and hardware may be evaluated together, but the screen still needs to work at each physical service point. Ask for written confirmation of the exact configuration and any unresolved compatibility questions before committing.
Next step: Request a demo of the Fleksa restaurant POS with the quoted screen. Bring your sample practice order and ask the vendor to demonstrate it at both the counter and the glare-prone position, using a simulation that cannot trigger real transactions or messages.
Frequently asked questions
Is a brightness specification enough to choose a POS screen?
No. It can help compare candidates, but check the actual screen and order-entry layout under the light and angles staff will encounter. Reflections and small text can still make a display difficult to use.
Should we test every device separately?
Test each device type and important service position in scope. A counter terminal, handheld and kiosk can face different light and viewing angles, even within the same restaurant.
What if the screen fails only in direct sun?
Try a workable position or shade and repeat the affected tasks. If the restaurant needs the device in direct sun and it still fails, do not approve it for that use. Record who owns the follow-up and when the team will retest.
