Is Samsung CF791 useful for home

Monitors

The Good The Samsung CF791’s 34-inch curved display is great for gaming, and the combination of 100GHz and FreeSync refresh rates goes well with the mid-range Radeon cards. Plus its color pleases.

The Bad It has only two USB ports, and its built-in stand makes life difficult for VESA members.

The Bottom Line The large, bright and accurate enough, the 34-inch curved Samsung CF791 is a bit expensive for the FreeSync monitor, but offers a great range of features and reliable performance if you’re a Radeon gamer.

I have enough ambiguity about curved monitors to fill a 34-inch screen. For games? Undoubtedly, this is good. He pauses for movies and work. Most movies use a 16: 9 or 16:10 aspect ratio, so at best they float in the middle of a 21: 9 screen. For example, you can conveniently place three windows side by side, but if you only need two, none are right in front of you look at the space between them.

With these caveats in mind, the 34-inch Samsung CF791 (to be exact C34F791WQN) is a great option in this class.

This is great for gaming, with fast enough response times, reliable AMD FreeSync implementation (with a maximum refresh rate of 100 Hz, you also get some freedom to work with lower Nvidia processors), bright colors and a reasonable amount of configuration flexibility. Field of view, people.

It’s not cheap, but I don’t think its $ 950 is unreasonably high for what it offers. In the UK, it costs £ 800. I don’t see it being offered in Australia, at least so far (for example, the price in the US is directly converted to $ 1,050). Samsung also offers a less expensive display – the Samsung price is higher but it has a lower street price – the SE790 (technically the LS34E790CNS). However, it does not support FreeSync and does not use the firm’s Quantum Dot technology, and is less curved.

Installing it dead is easy, mainly because the stand is built-in. It rises or falls as it slides along a track that simultaneously tilts it. In other words, at the highest level you are watching it straight ahead. At the lowest level, she leans back, so you look at her. You can adjust the amount of tilt by giving the cabin feel that it is a convenient way to change your neck and upper back. This is probably a good fit for standing tables.

Use the Samsung CF791 monitor for some work but mostly play

You can configure the inputs of HDMI and the full-size DisplayPort for simultaneous display in Picture-in-Picture or Picture-in-Picture modes, as well as HDMI output for signaling to another monitor or TV.

Because they are located on the left side and are not locked by hand, the connectors are really easy to reach. And although I’m not crazy about white and silver, it’s much easier to read the labels on the connections than with many dark cabinets.

I also like the one-touch joystick design of Samsung to navigate the screen and settings. But that means there is no way to match special presets or FreeSync modes for direct access. Samsung Magic Bright ($ 30 at Walmart) In fact, it concerns its pre-set modes, not the brightness, but its “Basic” mode – sRGB. In fact, there are many ambiguities in OSD: for example, there are Mode1, Mode2, and Mode3 in gamma mode. But there is a decent set of options, including dynamic contrast, a black HDMI level (which, in my opinion, is needed to compensate for the Quantum Dot panels). Magic Upscale basically overlaps everything.

No surprises

Like most consumer displays, the CF791 comes out of the box, ready to show all the colors it can to make the scenes pop, precision cursed. If you are color-sensitive, you can choose sRGB Basic settings because its gamut exceeds sRGB. It tests at about 125 percent for the index, pushing significantly into the less saturated greens and slightly the other way.

Quantum Dot backlighting is usually cooler than standard white LEDs. High brightness controls this. Usually blue is pulled back a little, allowing the CF791 to provide a color temperature of approximately 6300 K and a maximum contrast ratio of 1704: 1. In High Bright mode, the color temperature is checked to 6600K and the contrast ratio is increased to 2600: 1.

I find High Bright inconvenient to use and it is less accurate than in standard modes. In general, the monitor is accurate enough to randomly edit photos and videos in sRGB. The maximum brightness of the display reaches 290 bolts, which does not win any awards, but I have reduced that brightness to 17 percent as I write this, and the gamut matters more for most current games and streaming video in HD.

However, the display is really sensitive to the viewing angle. Brightness drops sharply, making it look low contrast in off-axis areas, so you either have to ignore it or place it carefully. The theory is that when the display is bent, you’re always sitting in a sweet spot, so off-axis artifacts don’t matter, but that’s not always the case. I have seen complaints of vignetting (dark corners) and bleeding highlights, but my assessment unit has also not suffered.

There were no surprises in terms of FreeSync performance. Using a standard RX 570 engine and forcing Doom (Vulkan) to a frame rate below 60 frames per second did it well. It looked better in Ultimate, but when the frame rate dropped to the 48-53 fps range and low frame rate compensation began, there was a slight flicker. Bioshock Infinite had a lot of tears in the initial scenes that went away with Ultimate, but it was probably Bioshock’s fault.

Built-in 7 Watt Stereo Speaker … OK. They are good enough to indicate that something has exploded, but not best for music or the environment.

Buy or no buy

Samsung’s 34-inch curvilinear Quantum Dot display is one of the best I’ve seen so far thanks to its wide color gamut and relatively accurate color. When you rush into its robust FreeSync implementation and pressed 100GHz refresh rate, it will also win the day for Radeon fans.
