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.
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.
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.

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.
The diagonal is the distance between two opposite corners of the screen, indicating the overall size of the display. It is usually written in inches (″) and does not include the variously wide screen bezels, so the final size of the device is usually slightly larger.
IPS, or In-Plane Switching, often also known as Super TFT, is a type of LCD display technology. It offers an excellent quality-price ratio, natural colours, low power consumption, and wide viewing angles up to almost 180 degrees.
Often dubbed the display of the future, OLED displays are usually found on premium products. They offer high quality, a broad range of colours, low power consumption, high brightness, and excellent black colour reproduction. As a result, OLED displays are easy to view even in bright sunlight. Another advantage is the wide viewing angle, which reaches nearly 180 degrees.
VESA uchycení je normou, která usnadňuje orientaci zákazníka při nákupu držáku k televizi nebo monitoru. Sjednocuje vzdálenost upevňovacích otvorů, tedy rozteč, na zadní straně televize a držáků. Jak to funguje a jak se v číslech orientovat, zjistíte v našem článku.
Expressed in hertz (Hz). Represents the number of frames per second that the screen can show. A larger value provides a smoother picture, which is especially important for sports, action movies and games. We recommend a refresh frequency of at least 100 Hz.
