Customer Ratings & Reviews

Hi, Trrravis. Thank you for reaching out and sharing your experience with the LG Monitor (27MR400-B) model. We understand how important it is for your display to perform reliably, especially with limited use over a short period.

If your monitor powers on intermittently and displays erratic volume behavior, we recommend trying the following steps: Disconnect the monitor from power for at least 60 seconds, then reconnect to perform a soft reset.

Check the control buttons on the monitor to ensure none are stuck or being triggered unintentionally.

If possible, test the monitor with a different power cable and input source to rule out external issues. https://www.lg.com/us/support/help-library/lg-monitor-screen-power-is-on-and-off-intermittently--20154629827130.

Hi, Steven. Thanks for sharing your thoughts on the LG Monitor (27MR400-B) model. It’s great to hear you’re enjoying the size and clarity — that IPS panel really does deliver crisp visuals. But we totally get your concern about the lack of built-in speakers, especially when it’s not clearly highlighted in some listings.

Many slim-profile monitors prioritize display quality and design over integrated audio, which can be a surprise if you're expecting an all-in-one setup. If you’re still looking for a clean audio solution, you might consider compact soundbars or USB-powered speakers that sit neatly under the monitor without cluttering your desk. You can find more details about your monitor’s specs and compatible accessories here: https://www.lg.com/us/support/product/lg-27MR400-B.AUSQ. If you’d like help finding speaker options that pair well with your setup, feel free to email us at lgdigitalcare@lg.sprinklrsupport.com. We're here to help. ^Juvy

Hi, Natalie. Thank you for reaching out to us. We understand how important it is for your LG Monitor (27MR400-B) model to remain reliable beyond the warranty period, and we appreciate you sharing the details of your experience.

For a monitor that has become nonfunctional due to a capacitor issue, one helpful step is to check if the unit powers on with a different outlet or surge protector to rule out external electrical factors. Additionally, reviewing the warranty and service options for your model can provide clarity on available repair or replacement paths.
