The desire to reach new levels of productivity have led to the advent of a new class of monitor: ultrawide. These large, widescreen monitors offer the ultimate in office productivity, allowing you to place two or more full-screen windows side-by-side, without the need for a multi-monitor setup. These ultrawide monitors have become popular with gamers as well, as they deliver a more immersive gaming experience. Like anything else, ultrawide monitors are not all created equal.
The Dell U3818DW is the best ultrawide monitor that we've reviewed so far. It has a huge 38" screen and impressive 3840x1600 resolution that is outstanding for multitasking. The U3818DW also has a unique set of connections, that allows you to control and see two computers at once, with a single keyboard and mouse, great if you work remotely and want to connect your work laptop to your home desktop.
Like most Dell monitors, it has a clean, professional look that fits well with any decor. It has a great stand that doesn't take up much space, and it can be easily adjusted to the most ideal viewing position. The U3818DW is also a very good gaming monitor. The widescreen and impressive resolution provide for an extremely immersive gaming experience, although it doesn't support any VRR technologies like FreeSync, and the 60 Hz refresh rate may be limiting to some users.
Overall, the Dell U3818DW is a versatile 38" monitor that should please most people.
If you want something a bit better for gaming than the DellU3818DW, the Dell Alienware AW3418DW is the best ultrawide gaming monitor that we have reviewed so far. The large, 34", 3440x1440 screen delivers a more immersive gaming experience. It has a great design, with a decent stand that can be adjusted easily. It has good wide viewing angles, which combined with the gentle 3800R curved screen, means the edges of the screen remain accurate, even when sitting up close.
The AW3418DW is a great gaming monitor. It supports NVIDIA's G-SYNC technology, and although it defaults to a 100 Hz refresh rate, it can easily be overclocked to 120 Hz when connected via DisplayPort, but you'll need a recent graphics card to do so. It has excellent low input lag, and some nice additional gaming options, including a Frame Rate counter, timer, and AlienFX Lighting feature.
Like most IPS monitors, it doesn't perform as well in a dark room. It has bad black uniformity with very noticeable flashlighting around the corners. It has a flicker-free backlight, but surprisingly lacks NVIDIA's ULMB feature. The AW3418DW also has below-average accuracy out of the box, but even some minor settings changes can correct some of that. Overall, it is a good monitor for most uses and it should please most people.
If you like the Dell Alienware AW3418DW, but would prefer something a bit cheaper, check out the ASUS PG348Q. Both have 34", 3440x1440 screens, but the PG348Q defaults to a simple 60 Hz refresh rate compared to the AW3418DW's 100 Hz. Both support G-SYNC VRR, which is great, and both have a similar design. The PG348Q is slightly brighter, but the unit we tested had worse dark scene performance, as there was significant flashlighting in the corners. This can vary significantly between units though.
If the Dell Alienware AW3418DW is too expensive for you, the LG 34UC79G-B is the best budget ultrawide monitor that we have reviewed so far. Like the AW3418DW, the 34UC79G-B has a 34" panel, but it runs at a lower 2560x1080 resolution, which isn't quite as good for multitasking. The stand isn't as good, as it lacks a swivel feature, but the height and tilt adjustments are good.
It is also great for gaming, thanks to FreeSync support and a faster 144 Hz refresh rate. It has excellent low input lag, and a much wider VRR range, ensuring a tear-free gaming experience. It also has an optional black frame insertion feature that can further reduce motion blur.
The IPS panel in the 34UC79G isn't great for late night gaming in a dark room, as blacks tend to appear gray and there is noticeable flashlighting. This is typical of IPS monitors. Unfortunately, it isn't great in a very bright room, as it isn't very bright and has worse than average reflection handling. Overall though, it is a decent ultrawide monitor that should please most people.
If the LG 34UC79G-B is still too expensive for you, get the LG 29UM69G-B. Visually, the 29UM69G-B is very similar to the 34UC69G-B, but with a smaller, 29" screen. Under the hood, it is a little more limited, as it has a maximum 75 Hz refresh rate, and it isn't curved. The stand is worse, and the height can't be adjusted. Unfortunately, it has horrible black uniformity and isn't a good choice for dark room viewing.
Overall, while it isn't a great ultrawide monitor, it is very cheap. If you want a large screen for occasional office work in a decently lit room, the 29UM69G-B is an okay choice.
