Direct LED: Čo to je a ako funguje?

Direct LED je jednou z technológií podsvietenia obrazu, ktorú využívajú LED televízory. V čom spočíva, aké má výhody a nevýhody a ako sa odlišuje od RGB LED alebo Edge LED?

Dual-link DVI vs. Single-link DVI

In addition to the fact that DVI can be adapted to transmit a purely digital DVI-D signal or a combination of analog and digital DVI-I, there are two different versions that differ in data throughput. The original version is called single-link, and you can get by with it on all Full HD monitors at the standard 60Hz refresh rate. The dual-link version doubles the bandwidth and can be used for resolutions such as 2,560 × 1,440 at 60 Hz.

American Wire Gauge (AWG)

Jednotka American Wire Gauge (AWG) vznikla už v devätnástom storočí a je istou obdobou palcových mier. V Európe ju nepoznáme, ale za oceánom sa stále hojne používa.

Tienenie kábla

Tienenie kábla slúži ako „filter“ nežiaduceho šumu. Šum sa môže prejavovať zhoršenou kvalitou obrazového, zvukového alebo dátového výstupu. Proti rušeniu je vybavený aj celý rad napájacích káblov (spravidla ferritový valček pri konektory), pri ktorých ide však skôr o určitú poistku. Väčšina koncových zariadení, napríklad notebookov, obsahuje ešte priamo vo svojom tele kondenzátory, ktoré majú na starosť práve filtráciu napätia.

Čo je analógový výstup?

Viete, čo je analógový výstup, na čo slúži a aké sú hlavné rozdiely medzi analógovým a digitálnym výstupom? Máme pre vás článok, ktorý aj úplnému počítačovému laikovi prehľadne vysvetlí, ako analógový výstup funguje. Začnime jednoduchou skúšobnou otázkou. Čo znamená skratka VGA? VGA je štandard pre zobrazovanie grafiky na počítačovom monitore. Prvýkrát ho použila spoločnosť IBM už v roku 1987.

Čo je HDMI?

HDMI (High Definition Multimedia Interface) je dnes najpoužívanejší digitálny štandard na prenos videa, audia i internetu. Veľmi často sa využíva na pripojenie televízorov, monitorov alebo projektorov k multimediálnemu zariadeniu. Vďaka jeho rozšírenosti a všestrannosti existujú rôzne verzie a tvary konektora.

Čo je DVI?

Rozhranie DVI (Digital Visual Interface) slúži na prepojenie monitora s počítačom a zvládne prenášať analógový aj digitálny signál. Konektor, vrátane redukcií na spätnú kompatibilitu, existuje v rôznych variantoch. Rozhranie DVI je stále rozšírené, hoci ide o staršiu technológiu, ktorá už pomaly ustupuje. Čo je DVI? Aká je budúcnosť DVI? A aký je rozdiel medzi DVI-A, DVI-D a DVI-I? Odpovede nájdete v dnešnom článku.

Anti-reflective Display

Antireflexní displej je displej s povrchovou úpravou, která má zabránit odrazům okolního světla. Jak se ale liší od matného displeje, už nemusí být tak zřejmé. V tomto článku vám to vysvětlíme.

Colour model

A colour model is a colour space that uses the basic colours and blends them into the resulting colour.

TV tuner

A TV tuner (or television tuner) is a component that receives and decodes television broadcasts. With the tuner, you can display individual TV programs on a TV, monitor, or other devices. TV tuners are divided by the type of TV reception they can receive:1) DVB-T / T2 - tuner for receiving digital terrestrial (aerial) television broadcasts2) DVB-S / S2 - tuner for receiving satellite TV3) DVB-C - tuner for receiving cable TV broadcasting

G-Sync a FreeSync

Some game monitors feature G-Sync or FreeSync. Both are used to sync the monitor's refresh rate with the graphics card, thus enhancing image smoothness while playing games. While G-Sync is compatible with selected NVIDIA, FreeSync is compatible with selected AMD graphics cards.

Viewing angle

The viewing angle is the maximum angle from which you can still see the image on the monitor without changing the colour or contrast. Larger the viewing angles are better. The size of the viewing angle is directly related to the monitor panel type. While IPS and S-IPS monitors have the largest viewing angles (up to 178 degrees), PVA and MVA screens are a bit worse. TN monitors have the lowest viewing angles out of all of the monitor types.

Screen Size

The screen size is determined by the distance between the bottom left corner of the monitor and the top right. It is given in inches: one inch is 2.54cm.

Monitor Resolution

This specifies the number of pixels that a monitor can draw, horizontally and vertically. In general, the higher the maximum resolution a monitor has, the more detailed the image will be and the larger the work or game area can be. The standard of today's monitors is to have Full HD resolution (1920×1080 pixels).

Refresh Rate

The refresh rate is how many images a monitor can diplay in one second. It is given in Hz, and generally, the higher the refresh rate, the smoother the picture. A higher refresh rate puts less strain on the eye. You will most likely encounter a 60-75Hz refresh rate, with gaming monitors reaching up to 200Hz.

Colour Depth

Colour depth indicates the number of bits used for each colour component of a single pixel. It reflects the number of colours the monitor can handle; more bits means more colours, but it also means a larger the data size. Colour depth is especially important when working with graphics, photos, and videos.

Gamut

Colour gamut indicates the range of colours a monitor can display. New monitors cover the entire Adobe RGB colour range, providing more realistic colours than cheaper monitors with sRGB.

Flicker Free

Flicker-free (also known as Flicker Less) is a technology that aims to eliminate unwanted and annoying screen flicker. Although this flashing may not be apparent at first glance, it can cause eye strain and, in extreme cases, may also lead to damage.

Pivot

Pivot is a feature that allows you to rotate the screen 90 degrees vertically. This solution is suitable for reading long texts or websites, allowing for less scrolling and faster reading. However, this feature cannot be used for watching movies and playing games. Not all monitors support Pivot.

Low Blue Light

Low Blue Light technology (also known as BlueLightFilter) reduces the harmful blue light spectrum, eye strain and fatigue.
