Here is the test of the Samsung Odyssey C49G95 monitor which adds up the superlatives: giant 49-inch VA panel, Dual Quad HD definition, 240 Hz frequency, G-Sync / FreeSync, HDR compatibility, high brightness peak, etc. A riot of technology!

The very large Samsung Odyssey 49G9 monitor.

The very large Samsung Odyssey 49G9 monitor.

Apart from its disproportionate size, the Samsung Odyssey 49G9 is ultimately quite classic from the front, if not its very curved panel. Its radius of only 1 meter which seems to “encircle” the user. From the front, this monitor is mostly made of matte black plastic, be it the edges of the screen or the imposing Y-shaped stand.

The screen edges.

The edges of the screen are not particularly thin. We can even say that they are rather large compared to what is usually done in the market for monitors for players.

The different settings: height, tilt and a little rotation.

The different settings: height, tilt and a little rotation.

The monitor offers many ergonomic settings. It is thus possible to slightly tilt the slab between -3 ° and + 13 °, to play on the rotation on ± 15 ° to the left and to the right thanks to a ball joint, and above all to adjust the height to 12 cm. It is obviously not possible to switch to portrait orientation, the panel being much too wide.

The rear is not sober since if the front is mainly black, the rear is in shiny white plastic. The connectors are oriented downwards and the foot support acts as a cable passage. The monitor is compatible with VESA 100 x 100 mounts thanks to an adapter supplied in the box which can also be used as a wall mount. An imposing cover hides all the connections; a very good point.

The rear gives pride of place to the Infinity Core Lightning system which illuminates the back of the monitor. Colors and switching on frequency can be set directly from the monitor menus. This system brings the famous touch gaming to the monitor.

At the back of the foot, there is also a support for headphones.

The connection.

The connection consists of two DisplayPort 1.4 inputs, an HDMI 2.0b input compatible with HDCP 2.2, a headphone output and two USB 3.0 ports. This monitor does not have built-in speakers.

One joystick to do it all.

One joystick to do it all.

The clickable joystick is the most pleasant way to navigate the settings. Pressing the button turns on the monitor. Then, you have to move the cursor to the right to validate the choices and to the left to go back. It is possible to change the source, mode (presets) and access the settings (brightness, contrast, sharpness, overdrive, etc.). The menus are readable and navigation is quick. The four directions also give access to quick settings (choice of source, headphone volume, etc.).

On our standard 140cm wide and 60cm deep desk, this Samsung Odyssey 49G9 takes up almost all the available space. It must be said that if the foot is limited to 32.4 cm deep (for all the same 80 cm wide), the screen protrudes on the front, which brings the total depth to 41.5 cm. There is therefore a little less than 20 cm for the keyboard and the mouse. Our advice would be to opt for a desk at least 70 cm deep in order to be comfortable and not to have the impression of having your nose in the screen. Finally, the 49-inch (124 cm) slab, although curved, also occupies almost the entire width of the desk. Here again, we recommend that you opt for a desk at least 160 cm wide. The Dual Quad HD definition is very pleasant to use on a daily basis. It offers a substantial workspace without having to cheat on the scaling, as is the case on a 32-inch Ultra HD monitor, for example. On the other hand, in games, you need a very high-end graphics card to be able to use this monitor properly.

By lowering the brightness to 13 to obtain white at 150 cd / m², the Samsung Odyssey C49G95 consumes 54 W, ie a relative consumption of only 41 W / m². Despite its size and high definition, this monitor is therefore particularly economical since it is to date the first monitor to drop below 50 W / m²; the average being rather around 100 W / m². It consumes a minimum of 44 W of the brightness (64 cd / m²) and a maximum of 136 W (700 cd / m² over the entire panel).

On the left, average gray temperature: 6310 K. In the center, gamma curve at 2.4. Right, average delta E at 3.6.

Out of the box, the Samsung monitor delivers a decent, but not perfect, picture. If the temperature curve is stable around an average measured at 6310 K – and therefore close to the 6500 K reference -, this is not the case for the gamma curve where the dark grays are blocked. The average measured at 2.4 – instead of the expected value of 2.2 – clearly reflects this difference. Finally, with a delta E of 3.6 – greater than the threshold of 3 below which the eye can no longer differentiate between ideal colors and the colors displayed – the colors cannot be considered as perfectly faithful.

On the left, average gray temperature: 6340 K. In the center, gamma curve at 2.3. Right, average delta E at 2.8 (sRGB mode - brightness 13).

By choosing sRGB mode and then lowering the brightness to 13 to obtain a white close to 150 cd / m², the results are noticeably better. The temperature is slightly closer to the 6500 K of the video standard, while the average gamma drops to 2.3. Finally, with an average Delta E of 2.8, the colors can be considered to be overall faithful to those sent by the source.

On the left, average gray temperature: 6520 K. In the center, gamma curve at 2.2. Right, mean delta E at 1.5.

Personalized calibration of the screen using a probe results in simply perfect image quality. The color temperature is based on the reference temperature, the gamma is perfect and the colors faithful. It’s a little frustrating to think that this panel does not arrive perfectly calibrated from the factory, as some manufacturers (Asus, Dell or ViewSonic) offer on high-end monitors.

Thanks to its VA panel, this monitor displays good native contrast, with black down to 0.07 cd / m², which tranhooly-news.coms into a contrast ratio greater than 2000: 1. This contrast remains quite far from that observed on the best VA monitors on the market, such as the Philips Momentum 436M6 where the MSI Optix MAG271CR (over 4000: 1), resulting in a rating of 4/5. However, this contrast is higher than that offered by IPS monitors which generally rotate around 1000: 1 and provide sufficiently deep blacks. Above all, this level of black associated with the very high brightness of the panel makes it possible to deliver a beautiful HDR image, especially as the colors are faithful, as we have seen in this article:

The average difference in white homogeneity is only 6% on this huge 49-inch slab. There is thus no variation in brightness perceptible to the eye. On the other hand, we were able to see light leaks on the sides, a recurring problem on large curved monitors where light leaks are difficult to control. However, we have not seen any clouding (cloud effect) on our test model. VA technology also offers fairly average viewing angles. The colors are homogeneous when looking at the screen from the front. On the other hand, one can observe a change of colors to more than 45 ° on the sides. The curved panel makes it possible to partially erase this problem as long as we stay in the right place, that is to say perfectly facing the center of the screen.

The Samsung Odyssey C49G95T does not use Pulse Width Modulation (PWM) to adjust brightness; it is therefore devoid of flickering and does not cause headaches to those who are sensitive to this phenomenon. Samsung offers only one preset to reduce blue light in a software way.

This monitor manages FreeSync Premium Pro and G-Sync between 48 and 240 Hz and therefore works best when the graphics card sends between 48 and 240 frames per second. It also supports LFC which quadruple, triple or double the number of images displayed in order to maintain a feeling of fluidity. At 20 frames per second, for example, the monitor operates at 80Hz and quadruples the number of frames. At 30 frames, it operates at 90 Hz. It does not use the CFL between 53 and 240 Hz. The supported range is therefore very wide and covers all uses. To take full advantage of this monitor, you need a very powerful graphics card. Indeed, the graphics card must be able to manage the 7.3 million pixels of the Dual Quad HD definition. This is a little less than the Ultra HD definition (8.2 million pixels), but this is to forget that this screen can go up to 240 images per second, or four times the normal rate (60 Hz). In practice, therefore, at least one GeForce RTX 3080 (or even a GeForce RTX 3090) or a high-end Radeon model (Radeon RX 6800 or higher). Obviously, performance depends on the games chosen, but to reach 240 Hz with native definition in recent games, you clearly should not skimp on power. In all cases, the fluidity is there and the image does not suffer from tearing problems (tearing) or jerks (micro-stuttering) using frequency synchronization technologies.

This Samsung monitor does not have a system for inserting black images via backlight scanning. As a reminder, when this system is present, it makes it possible to deceive retinal persistence and improve the sharpness of moving images. Fortunately, the screen is still very responsive and the sharpness is already very good without it. Too bad all the same not to have integrated it on this 240 Hz panel.

We measured the afterglow time at 4.5 ms with the overdrive (“Response time” in French in the OSD) set to “fast”. The different settings offered (standard, fast or accelerated) have very little impact on the screen. The Samsung 49G9 is one of the most responsive VA monitors on the market. It rivals the fastest models equipped with a TN panel, such as theAlienware AW2518HF 240 Hz flashed at 3 ms, but the VA panel offers better contrast. We measured the display delay (input lag) at 24 ms (at 60 Hz) via the HDMI input; quite a high value. So we had to bring out our Hyundai ImageQuest CRT monitor as we did it with the Panasonic GX800 TV. The display delay in DisplayPort is thus limited to 8 ms, a very small value which results in an almost zero lag between the action performed with the mouse or keyboard and its repercussion on the screen.

The Samsung Odyssey 49G9 monitor is a monster in every sense of the word. Imposing by size, it is also by its characteristics. Responsive, very bright and immersive, it does not disappoint … provided it is equipped with a very, very high-end graphics card, the price of which will be in line with that of the beast.
