  • QuestionI purchased this monitor 12/23/25, didn’t start using it until 1/4/26 and today 1/25/26 the monitor will not turn on. Tried new outlet, performed hard reset with no luck. Need help!

    Asked by Dherr.

    • Answer If the LG - 27" IPS UHD 60Hz 5ms Smart Monitor with HDR10 (HDMI, USB-C) - White Model # 27U731SA-W, is not turning on; you may have a faulty AC/DC Adapter. When you say you "performed a hard reset with no luck", that indicates that the power light turned on, but you are not getting a picture. If that is the case, check your video cables to ensure they are connected securely. If not, you can try unplugging the monitor power cable and waiting about 30 seconds, reconnecting the cable, and then turning on the monitor. If that does not resolve the issue, the monitor will require a service repair...^Ivan.

  • QuestionIs there a lag when connected to Playstation 5?

    Asked by Jean.

    • Answer Hi, Jean. Thanks for reaching out with your question about the LG Monitor (27U731SA-W) model. It's great that you're looking into its compatibility with your PlayStation 5. This 27-inch 4K UHD IPS Smart Monitor is designed for both productivity and entertainment. You can connect it via HDMI, but note it has HDMI 2.0 ports, supporting up to 4K at 60Hz. This allows for smooth visuals at 60 frames per second, but it won't support 120Hz gaming available in some PS5 titles. To optimize performance, remember to: - Set your PS5 to output at 4K resolution with a 60Hz refresh rate. - Use a high-speed HDMI cable rated for 4K. - Disable unnecessary video processing features in the monitor's settings, like “Super Resolution” or “Noise Reduction,” to reduce input lag.
