When it first tipped up three years ago, LED backlighting was the must have technology for folk using their PCs and monitors for anything that needed accurate colour reproduction. The contrast ratio is a property of a display system, defined as the ratio of the luminance of the brightest color white to that of the darkest color black that the system is capable of producing. If you continue to use this site we will assume that you are happy with it. In practice, color temperature is only meaningful for light sources that do in fact correspond somewhat closely to the radiation of some black body, i. The choice between the two is simple. Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. Sign in Recover your password.

The physical dimensions of the allowable angle, hereinafter – the viewing angle, are determined by several factors, the main ones are the type of “liquid crystal” and cycles powering. In practice, color temperature is only meaningful for light sources that do in fact correspond somewhat closely to the radiation of some black body, i.
The GWL has good contrast, natural colours and a functional design, but the low resolution and two year warranty let it down even at this low price.
The limited x native resolution which can feel cramped on-screen, especially if you want to work with multiple windows open at once – but at this price you can afford to think of it as a second monitor that you use for image manipulation or the darkest gaming. Dynamic Contrast not only forces you to choose one of the over-saturated preset modes, but we found the bneq in brightness during transitions between dark and light scenes in films far too obvious and distracting.
The bandwidth is measured in MHz and characterizes the maximum possible number of points to be displayed on a second screen. Since the viewing angle is usually less than desired, each LCD unit acquires the reference viewing direction during its manufacture.
It’s a shame more manufacturers are not following BenQ’s lead.
Now though BenQ has released a wee fella called the GWL for under a ton t920wl can do the job for you. A high contrast ratio is a desired aspect of any display.
If you continue to use this site we will assume that you are happy with it. Brightness refers to an absolute term and should not be confused with Lightness. The bandwidth depends on the number of pixels vertically and horizontally, as well as the vertical frequency refresh screen. Lower numbers mean faster transitions and therefore fewer visible image artifacts.
Our Verdict Apart from the slightly limited resolution this monitor ticks all the right boxes for a budget quality panel.
As LCDs do not produce light by themselves unlike for example Cathode ray tube CRT displaysthey need illumination ambient light or a special light source to produce a visible image. Older monitors with long response times would create display motion blur around moving objects, making them unacceptable for rapidly moving images. However, the promise of better contrast thanks to the LED backlight proved to be unfounded when compared against traditional g90wl, and we noticed some unevenness in our white-screen test.

BenQ GWL 19 Wide TFT Monitor LED Backlight | Best prices online guaranteed in the UK!
TechRadar pro IT insights for business. A backlight is a form of illumination used in liquid crystal displays LCDs. The image contrast is heavily dependent on the angle of view on the LCD panel falls.
At certain angles the contrast reaches a maximum, genq the image is easy to read, with other contrast sharply decreases and screen reading very difficult. Against Resolution could be cramped to some. Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light.
Plus, contrast can be turned up to per cent without over-saturating light scenes. It’s a sharp, clear panel, with a thoroughly impressive viewing angle and great black representation. Response time is the amount of bwnq a pixel in a display takes to change.
BenQ G920WL 19 Wide TFT Monitor LED Backlight
benqq Follow TechRadar Reviews on Twitter: As is known, LCD display with limited viewing angle. With this pricing even if you’re just an amateur g902wl or designer you’ve now got the chance to cadge a display that you can trust to give you a proper representation of your chosen images.
Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. The contrast ratio is a property of a display system, defined as the ratio of the luminance of the brightest color white to that of the darkest color black that the system is capable of producing.
