For example, 1800R means if you were to put the monitors side-by-side they could form a perfect circle 3.6 metres in diameter. It also refers to the typical eye-to-screen distance of 1800mm (1.8m) to see a 180° arc.

A 49”, 1,800R curve puts you in the driver’s seat and is the tightest curve you can see edge to edge sitting around 600mm (arm’s length) from the screen.

A 3,000R or 4,000R curve (slightest) is fine for a TV where you are sitting say 3-4 metres from it.

What is better for gaming – curved or flat?

This is entirely a personal choice. Many Pro gamers say that curved screens focus or centre them (but they are mainly referring to 27-32” single 16:9/21:9 monitors), and games are rendered to be in pseudo 3D anyway – not flat 2D.

In business there can be issues with curved monitors displaying skewed grid lines – a curved Excel spreadsheet grid spread over 49” could be a little too much.

As a business user I really appreciated having four full-sized A4 pages open at once, or a half screen browser and two A4 pages etc., – that is real productivity.

QLED is way better than ordinary LED

QLED – quantum dot – is the technology that Samsung use in its premium LED TVs and monitors. QLED has no relation to OLED (organic light-emitting diodes) that self-emit light.

QLED is still LED (light emitting diode), either edge-or-back-lit, but the different nano-sized Quantum Dots emit different colours (red and green) when hit by a blue LED backlight. The result over ordinary LED is better, more saturated colour, brightness, and faster response times.

Bottom line – Samsung has tuned the QLED to deliver game levels of better colour and deeper blacks as well as HDR (high dynamic range) to add definition to dark areas and cut down flare from light areas. HDR only works with HDR enabled games and movie content.

Samsung says the factory–calibrated game display modes optimise black gamma levels, contrast ratios, sharpness and colour value settings for any game genre.

To do that it has several pre-set modes – FPS, RTS, RPG, AOS (92% Adobe RGB), sRGB (125%), Cinema (DCI P3 90.5%), Hi-Brightness, and custom modes.

Brightness is good at up to 600 nits (typical 350), and contrast is up to 3000:1.

Freesync and refresh

The VA panel is capable of 144Hz refresh – you can also adjust it to 60/120Hz for older games. It supports AMD Radeon Freesync – we cannot verify if it supports Freesync 2 standard as stated on some websites.

1m/s MPRT (Moving Picture Response Time) is not the same as 1m/s GtG (grey-to-grey). Gamers say that MPRT is a more accurate representation of visible motion blur. In any case, human eyes cannot see below 25m/s.
