LED vs LCD Monitor Guide
Buyers meet the wordings LED and LCD together so often that they are easy to confuse. This guide explains what each wording describes, in qualitative terms, without publishing any specification figure. The LED wording on this site appears only in the second hand 19 inch LED desktop listing, taken from that listing itself.
What this page covers
The confusion comes from the fact that the two words describe different parts of a screen. LCD describes the panel that forms the picture, while LED describes the light source that lights that panel in many modern screens. A screen sold as an LED monitor is therefore usually an LCD panel with LED backlighting, not a screen that forms its picture from LEDs. For a buyer, that distinction matters less than the practical questions: the size, the readability in the room light, the viewing distance, the touch behaviour and the overall dimensions. A buyer who is offered an LED monitor should ask the same questions as for any screen, and should not pay a premium for the LED wording alone, because the wording by itself promises nothing about resolution, brightness or condition.
Key points for buyers
LED and LCD are two wordings that buyers often meet together, and they describe different parts of a screen. LCD describes the panel that forms the picture, while LED describes the light source behind that panel in many modern screens. A screen described as an LED monitor is therefore usually an LCD panel with LED backlighting, not a different kind of picture-forming technology. For a buyer, the practical questions are the same as for any screen: the size, the readability in the room light, the viewing distance, the touch behaviour and the overall dimensions. This site lists a second hand 19 inch LED desktop line, and the LED wording there is taken from the listing itself; no other category on this site carries a backlight statement, and none should be inferred.
A fair comparison starts from the buyer's own requirements, not from a feature list. The useful dimensions are usually the setting, the viewing distance, the users, the daily workload, the cleaning routine and the service access, and each candidate should be judged against those dimensions in turn. A comparison that ranks candidates by a single figure, or by a feature that the buyer does not need, will mislead. Where a value is not listed for a category, the comparison should say so and treat the value as a question for the enquiry, rather than filling the gap with a generic figure or borrowing a figure from another category. The enquiry is then the place to close the gaps that matter, one by one, before an order is placed.
Screen size is only the diagonal measurement of the display, and it does not by itself describe a monitor. Two monitors of the same size can differ in resolution, in aspect ratio, in brightness, in touch behaviour and in overall dimensions, because the housing and the mounting form add their own measurements. The only size with a listed value on this site is the 19 inch second hand desktop LED line, and that size should not be used to infer the sizes of other categories, because no other size is listed here. A buyer comparing sizes should therefore read the description of each category on its own page, check the overall dimensions against the available space, and state the wanted size in the enquiry rather than assuming that a category comes in a familiar range of sizes.

Frequently asked questions
How do I get a quotation?
Send an enquiry naming the monitor category, the quantity, the intended application and the way the screen will be used. Commercial terms are confirmed per order, and values that are not listed for a category are confirmed in the enquiry. This site does not list fixed selling figures.
What documents can you provide for a unit I am considering?
Certificates are available upon request. Name the category and the document needed in the enquiry, so the correct document can be checked. No certificate name, number or issuing body is stated on this site.
Is the second hand line sold as new?
No. The second hand 19 inch LED desktop line is a used line, and every page that describes it keeps the second hand wording. Condition and warranty for a second hand unit are confirmed per unit.
