Q: QuestionIs this monitor compatible with Dell Precision 3551 laptop? And if I buy two to connect to my laptop do I need a docking station ?
Asked by Denden.
- A:Answer What connectivity does your Dell Precision 3551 laptop have and what resolutions does the graphics card in it support? The 27" IPS 3-Side Borderless FHD 100Hz AMD 100Hz FreeSync™ Monitor (HDMI) - Black, Model # 27MR400-B has a native 1920 x 1080 resolution which your graphics card should support. Connectivity for the monitor includes an HDMI port and a 15-Pin D-Sub connector (i.e. VGA Connector). Connecting dual monitors to a laptop is pretty straightforward if you use a docking station. However, that doesn’t mean all docking stations are compatible with your laptop or the multiple screens you intend to use, so you have to first make sure that your laptop is compatible with the docking station. And, also ensure that your docking station can support the resolution and the refresh rate you plan you use on the monitors...^Ivan.

Q: QuestionCan I use this monitor with an Xbox S? I connected it and it’s telling me “HDMI out of range”
Asked by Marsh.
- A:Answer Hello there, Marsh. The LG 27MR400-B monitor should work with your Xbox Series S, but the "HDMI out of range" error usually means the monitor isn't set to the correct resolution or refresh rate for your Xbox. Here are a few steps you can try to fix the issue: Check Xbox Display Settings: Go to Settings on your Xbox, then General > TV & display options. Set the Resolution to 1080p and check if the monitor now displays correctly. The monitor supports 1080p, so this should align with the monitor’s specs. Also, try setting the Refresh Rate to 60Hz, as the monitor has a 100Hz refresh rate, but some devices might not be compatible with higher rates. Try a Different HDMI Port: Sometimes, an HDMI port might have a compatibility issue. If possible, try switching to another HDMI port on the monitor. Adjust the Monitor Settings: Check the monitor's OSD settings to ensure it's set to the correct input and resolution. https://www.lg.com/us/monitors/lg-27mr400-b#pdp_specs If you still encounter issues, feel free to reach out to @LGUSSupport on social media for additional assistance! —Renzo

Q: QuestionWould this monitor be a good choice for iRacing?
Asked by Anonymous.
- A:Answer Hi there, thank you for your question. We understand you're considering the LG 27MR400-B monitor for iRacing. This monitor has several features that could make it a good choice for sim racing, including: Refresh Rate of 100Hz: While this isn’t the highest available for gaming monitors, it’s still a solid refresh rate that should provide smooth motion for racing games like iRacing. IPS Display: Offers vibrant colors and good viewing angles, which can enhance your racing experience, especially when looking at various on-screen indicators and details. AMD FreeSync: Helps reduce screen tearing and stuttering, providing a smoother gaming experience, particularly in fast-paced environments like racing. 5ms Response Time: A fast response time that is beneficial for reducing motion blur in fast-moving scenes. However, it’s worth noting that iRacing can be demanding in terms of performance. A higher refresh rate (e.g., 144Hz or 240Hz) and a lower response time (e.g., 1ms) are generally preferred by competitive sim racers for the most fluid experience. While the LG 27MR400-B is a solid monitor for casual racing, you may want to consider a higher refresh rate monitor if you’re looking for the best competitive edge. https://www.lg.com/us/monitors/lg-27mr400-b#pdp_specs If you need any further guidance or have specific questions, feel free to send us a private message on Social Media @LGUSSupport, and our team will be happy to assist you. —Renzo

Q: QuestionI bought this monitor about a month ago and I was under the impression that it was not able to tilt. It has always felt super stiff. I am just finding out it does in fact tilt. I can't seem to understand how and my screen is facing down which I hate.
Asked by rickrubin.
- A:Answer We struggled with the tilt feature when we first got it. We downloaded the manual and found the instructions there, and watched a You Tube video on the proper way to tilt it! Before we started really thinking, we were trying to figure a way to put something sturdy under the base of the monitor as mine was also facing downward. Please download the manual or watch a YouTube video as to how to do this!
