LG 38UC99-W vs Asus ROG Swift PG348Q

Impressive amount of on-screen real estate, excellent picture quality, exceptional connectivity, and great color accuracy puts the LG 38UC99-W above nearly all competitors in the market.

You can charge your laptop and have display output through a single cable thanks to the monitor's USB-C port.

You can access all the general features of this monitor using your mouse and a keyboard thanks to the LG’s On-Screen Control software.

Additionally, the On-Screen Control offers many screen split presets.

Having enough display real-estate to fit three vertically aligned Google Docs windows comfortably, the LG 38UC99-W is an excellent tool to boost up the productivity in everyday office duties, CAD/CAM applications, and many other fields.

Acing the near-cinematic aspect ratio of 21:9, the LG 38UC99-W is an excellent companion to watch movies because you won't see the black bars at the top and bottom of the screen when watching most movies.

The LG 38UC99-W features a built-in 20 Watt stereo speaker system which sounds fairly well compared to the 4-10 W speakers the competitors at this price point offer.

This monitor beats most of its premium competitors in terms of connectivity because it features a USB-C downstream port which has multiple parallel functions. First, you can use it to access the monitor's onboard USB hub. Second, it can be used for charging a USB type C compliant laptop. Finally, you can use it to receive video and audio signal from a computer.

Additionally, the LG 38UC99-W has two HDMI ports, a DisplayPort, and an inbuilt Bluetooth module.

You can connect this monitor to two computers so that each machine use half of the on-screen area. This might come in handy for those who frequently use a stationary desktop computer and a laptop.

Only the best monitors can match the LG 38UC99-W's contrast ratio, peak brightness, gamma, and color accuracy, as the monitor features one of the finest IPS panels in the industry.

The LG 38UC99-W displays beautiful pictures, with deep and rich blacks, vibrant and accurate colors, and good-looking intermediate tones. Despite the fact that the monitor's native contrast ratio is only 1000:1, the dark scenes look deep and intense as the backlight of the 38UC99-W can drop below the brightness level of 0.15 nits, which only the best monitors can do. Colors pop and look vivid, as the 38UC99-W can sustain its brightness above the 300 nits mark. The mid-tones look lifelike thanks to the monitor's near perfect gamma value, which is only 1.3% off from the ideal value.

Moreover, the monitor's color inaccuracies can't be seen by the human eye because it only has an average color error dE of 2.12.

Getting the perfect viewing angles isn’t that complicated with the Asus PG348Q as it supports all the necessary ergonomic adjustments.

Ergonomics: It can be lifted up and down, turned right and left, and tilted up and down. So basically the screen can be adjusted to any dimension to suit your view angle.
Size: It has an optimum size (34") that looks great in games, movies and provides a lot of space to use your Windows applications side by side without ALT-tabbing between them. Any size smaller than this is a small screen (such as PG279Q) and any screen larger than this is too large for your eyes at a desktop PC-user distance.
Quality: Asus quality is behind this monitor. So no bug, no technical problems.

The monitor’s 3800R curve offers you an extra level of immersion as you can feel the panel surrounding you.

This Asus PG348Q is an excellent tool for content creators who like to capture, edit, and upload their gaming footage to YouTube or some other popular media services as the monitor offers a great amount of on-screen real estate, combined with the full sRGB coverage.

The monitor’s pair of 6 W integrated speakers sound surprisingly good and will come in handy outside of gaming.

You can use the monitor’s integrated USB 3.0 hub for charging and interconnecting peripheral USB devices. The hub consists of a single upstream and four downstream USB 3.0 ports.

The PG348Q looks good even from sides as the monitor offers some of the best viewing angles on the market. You’ll notice some color and shadow shifting only when the viewing angle exceeds 50 degrees, which is an outstanding result, as even the best IPS panels usually start to degrade at the 40 degrees angles.

The Asus PG348Q recreates relatively good-looking motion, with only some minor trails of motion blur following fast-moving objects on the screen. While fighting motion blur, the panel’s main weapon is the overdrive feature which allows each pixel of the Asus PG348Q to change its color within only five milliseconds. Unfortunately, some tiny trails of motion blur manage to get through.

Alternatively, you can use Asus’s ultra-low-motion-blur feature to eliminate the unwanted effect of motion blur, but that would cost you G-Sync, which can’t be used together with the ULMB.

Even while playing fast-paced FPS games, the Asus PG348Q feels highly responsive because of its low input lag of only 5,3 ms. Even though there are some faster panels available on the market, it is highly unlikely that you will be able to feel the 5,3 ms delay.

Monitor’s input lag is a time delay needed to process a frame generated by a computer.

G-Sync reduces stutter and eliminates screen-tearing as it allows the Asus PG348Q to synchronize its refresh rate to the framerate of a Nvidia GPU.

The monitor supports G-Sync in the 30-100 Hz range.

The Asus PG348Q comes with a rich selection of gamer-specific features, which include an FPS counter, timer, and multiple crosshair options. You can find those in the monitor’s GamePlus menu. All the elements are customizable.

The monitor’s native contrast ratio, peak brightness, gamma, and color uniformity are on par with what the best gaming monitors on the market offer.

The Asus PG348Q displays fascinating images, with crisp and vivid colors, accurate intermediate tones, and deep blacks. Colors pop and look vibrant thanks to the monitor’s peak brightness of 309 nits. Mid-tones look life-like since the monitor’s average gamma deviation is only 1.3% off from the perfect value. Blacks look rich and consistent because, while the panel’s native contrast ratio of 1081:1 manages to push blacks to relatively intense levels, the monitor’s overall uniformity dE of 0.78 ensures that the dark tones don’t blend with bright spots nearby. Such high color uniformity is a rare feature even for high-end monitors.

Moreover, the PG348Q’s color inaccuracies are virtually invisible to the human eye, because of it’s small color gamut error dE of 1.71.

The Asus ROG Swift PG348Q offers a combination of picture quality, responsiveness, and motion handling capabilities only the best gaming monitors can match. It is also equipped with a bunch of top-notch gaming features, like G-Sync, crosshair, and FPS counter.
