Skanderingshastighed

Appendiks

Skanderingshastighed, eller opdateringshastighed, angiver den frekvens, hvormed skærmen opdateres. Skærmdata transmitteres, når skærmen opdateres for at vise et billede, men opdateringen kan ikke ses med det blotte øje. Antallet af skærmopdateringer kaldes skanderingshastigheden og måles i Hz. En skanderingshastighed på 60 Hz betyder, at skærmen opdateres 60 gange i sekundet. Skærmens skanderingshastighed afhænger af ydeevnen af grafikkortene i computeren og skærmen.

Horisontal frekvens

Tegn eller billeder, der vises på skærmen består af en masse prikker (pixels). Pixels transmitteres i vandrette linjer, som derefter arrangeres lodret for at skabe et billede. Den vandrette frekvens måles i kHz og angiver, hvor mange gange de vandrette linjer transmitteres i sekundet og vises på skærmen. En vandret frekvens på 85 betyder, at de vandrette linjer, som udgør et billede, transmitteres 85.000 gange i sekundet, og den vandrette frekvens angives som 85 kHz.

Vertikal frekvens

Et enkelt billede består af mange vandrette linjer. Den lodrette frekvens måles i Hz og angiver, hvordan mange billeder der kan vises i sekundet af disse vandrette linjer. En lodret frekvens på 60 betyder, at et billede transmitteres 60 gange i sekundet. Den lodrette frekvens kaldes også "opdateringshastigheden", og den påvirker, om skærmen flimrer.

Opløsning

Opløsningen er antallet af vandrette pixels og lodrette pixels, som udgør en skærm. Den repræsenterer visningens detaljeringsgrad.

Med en højere opløsning vises en større mængde oplysninger på skærmen, og den er velegnet til at udføre flere opgaver ad gangen.

En opløsning på 1920x1080 består f.eks. af 1.920 vandrette pixels (vandret opløsning) og 1.080 lodrette linjer (lodret opløsning).

Plug & Play

Med Plug & Play-funktionen kan der udveksles oplysninger automatisk mellem en skærm og en computer for at opnå et optimalt visningsmiljø.

Skærmen anvender VESA DDC (international standard) til udførelse af Plug & Play.

This allows for vibrant colors and incredible contrast ratios, which enhance the viewing experience whether you're working on graphics, watching movies, or playing video games. The QLED panels deliver up to 1 billion colors, ensuring that the images produced are lifelike and vivid.

The LC27A750XS/EN features a larger 27-inch display, while the LC23A750XS/EN offers a compact 23-inch screen, making both models versatile for various workspaces. Both monitors boast a resolution of 2560 x 1440 (QHD), providing detailed visuals that are ideal for multitasking and productivity. The high pixel density means text is sharp, and images are clear, making them suitable for tasks that require precision.

Another standout aspect of these models is their image performance, which is enhanced by a fast refresh rate and low response time. The 144Hz refresh rate ensures smoother motion, which is particularly beneficial for gamers who rely on quick reaction times during gameplay. Coupled with a 1ms response time, these monitors help reduce motion blur, delivering a seamless experience.

Additionally, both monitors come with HDR10 support, which allows for a wider spectrum of brightness and color contrasts. This feature significantly improves the overall viewing experience, especially in HDR-enabled content, making blacks deeper and whites brighter.

The ergonomic design of the LC27A750XS/EN and LC23A750XS/EN also deserves attention. They offer a range of adjustments, including height, tilt, and pivot, enabling users to customize their setup for maximum comfort. This is an essential factor for those who spend extended hours in front of their screens.

Connectivity options are plentiful, with both monitors featuring USB-C, DisplayPort, and HDMI inputs. The USB-C port allows for easy connectivity with laptops and mobile devices while delivering power, data, and video through a single cable.

In summary, the Samsung LC27A750XS/EN and LC23A750XS/EN are sophisticated monitors that combine advanced display technologies, a sleek design, and ergonomic functionality. Whether for gaming, professional design work, or daily use, these monitors deliver an exceptional visual experience that caters to a variety of viewing needs.
