Five sizes, five resolutions
Touch screen monitors on this site come in five sizes — 12.1, 15, 17, 19 and 21.5 inches — each with its own resolution: 12.1 inches at 1280×800, 15 inches at 1024×768, 17 and 19 inches at 1280×1024, and 21.5 inches at 1920×1080. Size and resolution together describe a monitor: size describes its physical dimensions, resolution describes how many pixels it shows, and a monitor's usefulness depends on both, because a large monitor with a low resolution shows coarse text, while a small monitor with a high resolution shows text too small to read.
A buyer should choose by size first, then by resolution, because the size determines whether the monitor fits its mounting and its counter, while the resolution determines whether its content is readable at that size. The model pages give the per-size specifications, and the inquiry should name the size, because a size that is not named cannot be confirmed.
12.1 inches: compact and embedded
A 12.1-inch monitor suits a tight space or an embedded housing: a narrow counter, a small kiosk, or an equipment panel, where a larger monitor would not fit, and where the content is simple enough for a compact display. Its 1280×800 resolution suits its size, giving a readable display without crowding, and its compact footprint leaves room on the counter for a scanner, a printer, or a drawer, which a larger monitor would displace.
A 12.1-inch monitor also suits an embedded installation, where it becomes part of a machine or a cabinet, because its size fits a housing that a larger monitor cannot, and its weight is easier to support in a housing than a heavier unit. A buyer who needs an embedded monitor should name the housing and its dimensions in the inquiry, because an embedded unit must fit its housing exactly.
15 inches: the standard counter monitor
A 15-inch monitor suits a standard counter: a checkout, an industrial panel, or a kiosk, where a mid-size display is needed and space is not severely constrained. Its 1024×768 resolution suits checkout and industrial displays, where clarity matters more than high resolution, and its size leaves room on the counter for the other checkout pieces, without dominating the counter or leaving the operator to squint.
A 15-inch monitor is the most versatile size on this site, because it fits most counters and most uses, and a buyer who is unsure which size to choose should start from 15 inches and adjust only if the counter or the content demands it: a tighter counter points to 12.1 inches, while a need for more information on screen points to 17 inches or larger.
17 and 19 inches: larger displays for more content
A 17-inch or 19-inch monitor suits a counter or panel where more content must be shown: a table, a form, a control panel, or a menu with many items, where a smaller screen would force scrolling or squinting. Both sizes use 1280×1024 resolution, a squarer display that fits tables and forms better than a widescreen display, because a squarer screen shows more rows without scrolling, while a widescreen screen shows more columns that a table may not need.
The choice between 17 and 19 inches is about space and readability: a 19-inch monitor shows the same content larger, which suits a counter where the operator stands back, or a panel where the display must be read at a distance, while a 17-inch monitor shows the same content in less space, which suits a tighter counter. Both need a mount that holds them securely, because a larger monitor is heavier and needs a stronger mount.
21.5 inches: the largest, sharpest display
A 21.5-inch monitor suits a fixed counter or information point where a large, sharp display matters: a full high-definition 1920×1080 screen for detailed content, where the display is the centre of the installation and must be read clearly, even at a distance. Its size suits a fixed installation, not a tight counter, and a buyer who needs a 21.5-inch monitor should check the mounting method as well as the size, because a unit of this size needs a mount rated for its weight.
A 21.5-inch monitor also suits a display that must impress: an information point, a reception, or a premium checkout, where the display's size and sharpness contribute to the impression, as well as to its readability. A buyer who chooses 21.5 inches for impression alone, without considering its mounting and its content, may find it dominates a counter that needed a smaller unit, so the size should be chosen for its use, not for its impression.
Touch type and interfaces, by size
Touch type differs by model across the sizes: true-flat capacitive and resistive both appear, and each model page states its own touch type, rather than generalising one type to a size or to the family. A buyer who needs gloved operation should choose a resistive model explicitly, while a buyer who needs a bare-finger response should choose a capacitive model, and the inquiry should name the touch type, because a touch type that is not named cannot be confirmed.
Interfaces are VGA plus USB on all sizes, with HDMI as an OEM option, and the interface set should be confirmed for the exact model, because a monitor with the wrong interface cannot be connected without an adapter. A buyer who needs HDMI should name it explicitly in the inquiry, because the standard interface is VGA plus USB, and an HDMI model is a different configuration.
Mounting and space planning
Mounting should be planned with size: a panel mount needs a cutout of the right size for the exact model, while a VESA mount needs a bracket rated for the model's weight and size, and a monitor ordered without a mounting plan may arrive to find no suitable mount waiting. A buyer who plans mounting should name the mounting method and the space in the inquiry, so the supplier can confirm the method for the exact model, rather than the buyer guessing and discovering the mismatch on delivery.
Space planning should include the other checkout pieces as well: a monitor that fits its counter alone may not fit alongside a printer, a drawer, and a scanner, and a counter that is planned for the monitor alone will be crowded when the other pieces arrive. Plan the whole checkout, not just the monitor, so the counter works as a system, not as a collection of pieces that happen to share a counter.
Before you order a monitor
Name the model, the size, the quantity you have in mind, and the market you sell into, in the inquiry. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, the payment and shipping terms, and the certificates that apply to your market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order.
A monitor is only as good as its fit to its counter and its content, and the fit is only as good as the confirmation. The mounting guide explains the two core mounting methods, and the model pages give the per-size specifications, so a buyer who follows both will rarely be surprised.
A note on sources and confirmation
The model specifications and trade terms referred to in this article come from the company profile's official product pages, as presented on this site's model and category pages. Trade terms are stated per model only: minimum order, supply ability and stock time differ by model across the official detail pages, and delivery EXW, though stated on all 101 pages, is still written per model rather than as a blanket promise, and stock time is not delivery time.
Figures that are not stated on a model page — a price, a payment, shipping or warranty term, or a certificate for a specific model and market — are confirmed per order in the inquiry, and this article does not invent them. Official list prices that appear on the official detail pages are transcription only and are never a quotation, and no certificate name, number, or issuer is stated anywhere on this site, because none are evidenced; certificates are available upon request.
Before ordering, name the model, the variants, the quantities, and the market you sell into, in the inquiry. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the payment and shipping terms, the warranty terms, and the certificates that apply to your market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order, because payment removes the leverage to resolve an unconfirmed item, and a confirmed order is the only basis for a safe purchase.
