the best monitor on paper, but there is a problem


Samsung is finally releasing its brand new Odyssey Neo G8. Its data sheet is crazy, it shows 4K at 240 Hz. But there is a problem, we explain why.

Samsung has formalized the arrival of three new PC screens: the Samsung Odyssey Neo G8, Neo G7 and Neo G4. As the name of the range suggests, Odyssey, these are game oriented monitors. We already knew them, they were unveiled at CES 2022. If we talk about them now, it is because they are now being marketed.

The Neo G8 spec sheet is monstrous

The new 32-inch Odyssey Neo G8 is the first and fastest monitor in the world to combine a 4K resolution (3840 x 2160 pixel) 1000R curved VA panel with Quantum Matrix technology, an ultra-fast 240Hz refresh rate, and an ultra-fast 240Hz refresh rate. 1 ms response (GtG). 4K definition is also supported by a color gamut up to 95% of the DCI-P3 gamut. As you can see in the photos, its design is inspired by the huge Odyssey Neo G9.

The Neo G8 also uses Quantum Mini LED technology, which allows for detailed and precise control of the LEDs, and therefore better contrast (less outstanding than the OLED of course). Also, with Quantum HDR 2000 support, the maximum brightness is 2,000 nits. For once, that’s much more than what OLED technology allows.

4: 2: 0 downsampling is mandatory under these conditions

However, note a problem in this datasheet that seems very solid: to take advantage of 4K at 240Hz, you have to go through HDMI 2.1. In this specific case, the flow must be reduced to pass through the tube. To get there, the Neo G8 must follow a digital diet. In other words, Samsung applied a binary “weight loss” strategy with 4: 2: 0 sampling.

The basis of this technique is childish: our eye is less sensitive to spatial variations in color than to spatial variations in luminance (brightness). To take advantage of this, the images are not recorded in RGB encoding (where each pixel is assigned a value for red, green and blue), but in YCbCr. Therefore, each pixel always has three values. The method used here is subsampling, i.e. taking fewer samples than actually needed. The 4: 2: 0 model halves the horizontal and vertical definition.

Impossible to say if the result will be imperceptible to the naked eye, however it will undeniably complicate post-production. Chroma downsampling has an effect on image quality. Especially in very fine and very pronounced color models, some colors can fade. For everyday use, no problem exists. Almost all of the content we watch every day uses 4: 2: 0 chroma subsampling: DVD, Blu-ray, and even Ultra HD Blu-ray, plus TV, YouTube, Netflix, and more.

To take full advantage of 4K at 240Hz, you’d need a connection Display Port 2.0. As for HDMI, you will need to look at the side of the DSC (Display Stream Compression) which offers lossless compression of the video signal, but it is not known whether Samsung uses this technology.

Neo G7 and G4, more classic

Samsung is also expanding its gaming monitor lineup with the new Odyssey Neo G7, a 32-inch 4K (3840 x 2160 pixels) display with 1000R curved VA panel, 165Hz refresh rate and 1ms response time ( GtG). This performance is ensured by many of the same features as the Odyssey Neo G8 model, including AMD FreeSync Premium Pro, Quantum Mini LED technology and Quantum HDR 2000 with a peak brightness of 2,000 nits.

The G4 could prove to be a great option for gamers looking for a monitor with all essential gaming features. It is available in the 25-inch format, the G4 monitor with Full HD definition (1,920 x 1,080 pixels) and a refresh rate of 240 Hz, a response time of 1 ms (GtG). Here we have a more classic IPS panel with HDR10 support. All this with AMD FreeSync Premium and Nvidia G-Sync compatibility.
