Samsung says it uses an advanced “four-channel” impulsive scanning technology, which is more precise. It creates a cleaner visual experience by dividing the screen into four concurrent sections to remove motion blur more efficiently, and Samsung was the first to apply it to create a 1ms monitor.

Arena lighting and on-screen gaming performance panel

Rear lighting (from here you connect the strand) creates a subtle blue glow that looks quite nice. Alternatively, if you want even more light, you can remove the plastic surround that partially obscures it.

On-screen display

Like other Samsung gaming monitors, it has a joystick accessing a dashboard style performance bar and segments on Game, Picture, System etc. Samsung calibrates each monitor at the factory and its best to leave custom settings alone.

There are three buttons on the bottom bezel to change presets.

But how does a 3840 x 1080 resolution look?

Surprisingly good considering it is a 1080p vertical screen. We expected pixelation – there was none courtesy of the QLED panel. Visibility was good from all angles too.

Many games and movies now have HDR – but remember these are in 16:9 format, so you will have big back bars either side of the picture. There is an increasing number of 21:9 and 32:9 ratio games.

For business use too

Windows snap feature (right click on the taskbar time) allows easy manipulation of two or more screens.

There is also a Samsung app called Easy Setting Box to partition the screen into separate screens.

Perhaps the most interesting thing is to be able to use it with two separate computers each with 50% of the screen – cool.

My take is that business will prefer this monitor to two 27” screens – if you ignore price and have big desks.

GadgetGuy’s take

We wondered if Samsung was actually serious in making a 49” wide monitor or was it something dreamed up for a world gaming Congress to gain more attention like the show-stealing 146” The Wall TV shown at CES 2018?

While Samsung do have a sense of humour (you need to living below North Korea) we initially could not see the point in 15kg, 32:9, albeit a superb performing monitor.

Then we started to warm to it as the equivalent of two 24” (Samsung says it is equivalent to 2 x 27”) and what that may do to games and office productivity.

If you’re a gamer, the CHG90 offers sheer immersive gameplay.

If you a business user think of it as two 27” monitors with one PC connection.
