A guide to choosing a screen

How to choose a Smart TV for a currency rate board?

Start with where customers will read rates and how many currencies you need. Then choose the size, system and model. A good screen makes your offer easy to read.

Choose your screen step by step

Already have a TV? Try it with DCR first — you may not need a new one.

Step 1 · Location and distance

Measure the customer’s distance, not the sofa’s

Stand where customers make their decision: outside the entrance, at the counter or in the queue. The farther the board is, the larger its digits — and usually the screen — need to be.

  • Check the farthest point where the offer should be readable. Include customers viewing from the side.
  • With the same currency count, a larger screen allows larger digits. Higher resolution alone does not enlarge text.
  • Measure the available mounting width and height. A diagonal in inches does not tell you whether the device fits the window.

Film-viewing guides help with living-room TVs, but do not determine rate readability. Digit size, rows, contrast and customer distance matter here. Test your actual board at its intended location.

How much space does a 16:9 screen need?

DiagonalImage widthImage height
32″71 cm40 cm
40″89 cm50 cm
43″95 cm54 cm
50″111 cm62 cm

Approximate image dimensions for a 16:9 screen. The frame, stand and mount need extra space; check the specific model’s specifications.

Step 2 · Number of currencies

Count the rows before choosing the inches

Three currencies can fill a screen with large, clear rates. Dozens on the same area need smaller digits, a different layout or extra screens.

A few currencies: give them room

With 3–6 currencies, enlarge the key information. Remove unnecessary elements and check that customers can read the currency, buy rate and sell rate together.

A dozen or more: test the layout

Compare portrait and landscape, columns and the space used by logos and headings. A bigger diagonal does not replace a readable board design.

Dozens: consider several screens

Split the offer into groups, for example around 30 currencies each if still readable. One screen can show popular currencies and another the rest.

These are layout examples, not DCR limits or readability guarantees. Screen profiles divide currencies and layouts while keeping rate values centrally managed.

Step 3 · Tablet or television

A small board up close may not need a TV

Choose a device for how customers use your offer. No single size fits every exchange office.

A 10–12″ tablet at the counter or window

Start with 3–6 currencies read close up, roughly at arm’s length. For 7–9, test the actual layout and digits; if customers must lean in, enlarge the screen or shorten the list.

Close to the glass is not necessarily close to customers. A small tablet may be too small for people several metres away outside. Check reflections, heat and operation while plugged in.

A 40–43″ TV as a starting point

For a wall-mounted board read from several metres away, start comparing this size. With many currencies or greater distance, test a larger model or divide content across two screens.

A 24–32″ model may work in a small premises. These are sizes to test, not a table of compulsory viewing distances.

Step 4 · Appearance and mounting

Fit the screen to your premises without a distracting frame

A narrow black frame usually blends with a dark board. Look for a discreet logo; the device need not be completely unbranded.

  • Inspect the whole frame, including its bottom edge. Colourful promotional images may disguise the actual bezel width.
  • Plan hidden cables, power and network access. Check VESA compatibility, dimensions and permitted mounting orientation in the manufacturer’s manual.
  • Check reflections from lights and glass, and readability from the side. Brightness and glare handling may matter more at a window than decorative image features.
  • For long daily use, check the manufacturer’s operating-time and environment guidance. For demanding windows or 24-hour use, consider a commercial display.

Step 5 · Budget and specifications

Pay for readability and compatibility, not cinema features

In Poland, around PLN 700–1,000 can be a target when looking for a basic 40″ Smart TV or a promotion. Not every model fits this range; prices and promotions vary by market.

A standard LCD with LED backlighting often suffices

A rate board is mainly text and digits. In a typical interior, basic LED with enough brightness and contrast may work. Full HD is a reasonable starting point to test; readability matters more than a 4K label.

QLED, Mini LED, HDR and 144 Hz are not DCR requirements

QLED, Mini LED, Dolby Vision, HDR10+, 120/144 Hz, VRR and motion smoothing serve films and games. A static board does not need extra spending on them. At a similar price they are fine; higher brightness may help in bright locations.

Include the mount, cables and any external player in your budget. Compare energy use over your planned operating hours.

Step 6 · System and test before buying

Smart TV is a category, not an app compatibility guarantee

The system, model year and store region may affect app availability. The surest approach is to test the specific model with DCR before buying.

Android TV and Google TV

Check DCR installation on an Android TV platform, including Google TV interfaces. “Android” alone in a product description does not confirm a TV app store with the app you need.

Samsung Tizen

DCR has a Tizen client. Check availability in the specific TV’s store, install and test it. Samsung branding alone does not confirm every model or year is compatible.

LG webOS

Look for DCR in the store on the specific LG webOS model. Test installation, account pairing and daily startup rather than assuming every LG device is supported.

Older TVs or other systems: a browser

Open dcr-online.com/tv in the device’s browser. If it displays the board correctly, stays connected and hides browser controls in fullscreen, it can work too. Remote-control navigation and reopening may be less convenient than an app.

Open the browser rate board

Older browsers may not support modern pages or secure connections. Test this device. If it fails, consider a compatible HDMI player instead of replacing a working screen; test its system and app too.

Ask the shop to test the chosen model

If the seller allows an internet-connected test, follow these steps. Otherwise confirm app availability and purchase terms that let you test the device before mounting it.

  1. Find DCR in this device’s app store and check installation. For the browser option, open /tv.
  2. Pair the screen with a DCR test account and show your intended currencies, buy rates and sell rates.
  3. Check fullscreen without browser bars, readability from a distance and from the side, and correct orientation.
  4. Change a sample rate in the panel and confirm the screen updates.
  5. Leave the board on and check screensavers and auto power-off. This is a short test; also check behaviour after hours of use at your premises.
  6. Turn the TV off and on again. Check how many actions it takes to return to the board and whether settings persist. Do not assume every model starts the app automatically.
  7. After testing, unpair the device from your test account and remove data entered on the shop’s unit.

Frequently asked questions

It depends on distance, currency count and layout. Around 40–43″ can be a starting point for a wall board, but test the real offer from the customer’s position. For greater distance or many currencies, consider a larger screen or several devices.

Start with 3–6 currencies read close up. For 7–9, test the actual layout; this is not an app limit. Digit size, headings, orientation and distance matter. If text is too small, shorten the list or use a larger screen.

These are not DCR requirements. In a typical interior, a basic LCD with LED backlighting may suffice if digits are clear. Check brightness, contrast and resolution for your layout; bright windows may be more demanding.

No. There are also Samsung Tizen and LG webOS clients and the /tv browser mode. Check availability and operation on the specific model, accounting for its system, year and store region.

Yes, if its browser displays /tv correctly, stays connected and hides browser bars in fullscreen. Older browsers may have limitations, and remote-control startup can be awkward. Test rate updates and returning to the board after restarting.

No. DCR rate values are shared across the account, while profiles choose currencies and layout per screen. Duplicate the board or divide the offer between devices. The screen count depends on your plan.
