Description
The LG 34WP65C-B is a 34 inch curved ultrawide monitor at 3440 by 1440 in a 21:9 aspect ratio, using a VA panel and running at 160 Hz. It is positioned for both productivity and gaming, and the specification list supports both claims: the resolution and width suit side by side work, while the refresh rate and FreeSync Premium support suit games.
Ultrawide is a format decision more than a specification decision. Buyers should be sure they want a 21:9 screen rather than two separate displays, since some applications and many games handle the aspect ratio better than others. Those wanting conventional 16:9 displays can compare the AOC Q27G3XMN for gaming or the Dell E2423H for office work, and a similar sized curved conferencing display is covered in the Dell C3422WE.
Panel, Resolution And Screen Space
LG confirms the panel type as VA and the shape as curved. VA panels typically deliver deeper native contrast than IPS, which suits dark scenes and film viewing, with viewing angles better than TN and slightly behind IPS. The curve helps on a screen this wide by keeping the edges closer to a consistent viewing distance.
The resolution of 3440 by 1440 gives what LG describes as 33 percent more screen space than a Full HD display. In practice that means two full width documents side by side, or a video timeline with panels either side, without the bezel gap that two separate monitors introduce. For online meetings with a shared screen alongside notes, or for working with multiple reports at once, that is the core value of the format.
Color coverage is quoted at 99 percent of the sRGB spectrum with HDR10 support and 400 nits of brightness. LG positions that combination for photographers and graphic designers. It is worth being precise here: 99 percent sRGB is good coverage of the standard web and office gamut, and it is not the wider DCI-P3 or Adobe RGB coverage a print or video professional would want. 400 nits with HDR10 means the monitor accepts and displays an HDR signal, but 400 nits is modest for genuine HDR impact compared with displays certified at higher brightness tiers.
Gaming Features
The refresh rate is 160 Hz, which is a strong figure for an ultrawide at this resolution. AMD FreeSync Premium synchronizes the monitor’s refresh rate to the graphics card’s output, reducing tearing and stuttering, and the Premium tier adds a low framerate compensation requirement. LG names AMD Radeon cards specifically, though FreeSync generally works with compatible NVIDIA cards as well.
Three additional gaming features are listed. Dynamic Action Sync reduces input lag by minimizing internal processing. Black Stabilizer brightens dark areas of the image so that shadowed detail is visible, which is a competitive advantage in games and a distortion of the intended image in films. Crosshair overlays an aim point on the screen, which some competitive players find useful and some games and tournaments prohibit.
The listing does not state a response time figure anywhere, which is a notable omission on a monitor marketed for gaming. VA panels historically lag IPS on dark transitions, producing smearing in fast dark scenes, so the absence of a grey to grey figure is worth noting rather than glossing over.
Stand, Audio And Connections
The stand adjusts for tilt and height, which is more than many gaming monitors offer and directly affects comfort on a screen this large. The design is described as three side virtually borderless with slim bezels. The panel is 16.9 pounds with listed dimensions of 10.2 by 31.9 by 18 inches including the stand.
Built in speakers are rated at 2 channels of 7 watts each with MAXXAUDIO processing. 7 watts per channel is more power than the token speakers found in most monitors, so this is a usable option for video calls and casual listening, though a dedicated desktop pair from the computer speakers category will still sound better.
Connections are given only as HDMI and DisplayPort in the product title, with no port counts. The specification block separately lists one USB 3.0 port, which the description and bullets never mention. Buyers who need a specific number of inputs, or who want to know whether that USB port is a host connection or part of a hub, should confirm with LG. There is no USB-C connection mentioned, so single cable laptop connection is not available.
Highlights
- 34 inch curved VA panel at 3440 by 1440 in 21:9.
- 160 Hz refresh rate with AMD FreeSync Premium.
- HDR10 support with 99 percent sRGB coverage and 400 nits.
- Dynamic Action Sync, Black Stabilizer and Crosshair gaming features.
- Built in 7 watt per channel MAXXAUDIO stereo speakers.
- Tilt and height adjustable stand.
- Three side virtually borderless design.
- HDMI and DisplayPort inputs.
Things To Consider
The missing response time figure is the most significant gap for a gaming purchase. So is the incomplete port list: a monitor listing that does not say how many HDMI and DisplayPort inputs exist leaves a buyer unable to plan a desk setup. The Voltage field reads 240 volts, which reflects a different regional listing and is almost certainly not a limitation given that monitor power supplies are typically universal input.
LG’s marketing includes a category leadership claim about ultrawide monitors in the United States, sourced to NPD retail tracking data covering February 2020 through January 2021 with comparison periods back to 2018. That is a specific citation with a named research firm and a defined window, which is better practice than an uncited claim, but it describes sales volume from several years ago rather than product quality.
The ultrawide format itself carries trade offs beyond the monitor. Not every game supports 21:9 properly, some render with black bars or a stretched image, and video content is almost never in this aspect ratio. Graphics cards also have to push 4.95 million pixels at 160 Hz to reach the panel’s full capability, which is a real demand.
Customer feedback is strong and well sampled at 4.6 stars across 1,192 ratings, on a monitor first available in March 2021. That is the most reliable data point on the listing. Readers can compare other displays in the monitors category.
Who It Suits
The 34WP65C-B suits someone who wants one wide screen instead of two monitors for productivity, spends time in spreadsheets, timelines or side by side documents, and also games at high refresh rates. The height adjustable stand, the usable built in speakers and the 160 Hz panel make it a credible single monitor for both work and play.
It is the wrong monitor for color critical print or video work given the sRGB focused gamut, for anyone expecting high impact HDR at 400 nits, for competitive players who need a documented response time, and for laptop users who want single cable USB-C connection. Anyone unsure about the 21:9 format should try it before committing, since the shape is the whole product.
