Q: QuestionIs this monitor true 2.1 Display Port? Im hearing it cant do 80Gbps

Asked 6 months ago by Sadbuttrue.

• A:Answer The DisplayPort 2.1 ports on the LG 27-inch UltraGear OLED QHD 1440P 480Hz 0.03ms G-Sync® Compatible DisplayPort 2.1 Gaming Monitor, Model # 27GX790A-B are "true" DisplayPort 2.1 ports. DisplayPort 2.1 supports three UHBR rates: UHBR10 (40Gbps): Suitable for mainstream 4K/120Hz gaming and general multitasking. UHBR13.5 (54Gbps): Supports 8K/60Hz with Display Stream Compression (DSC), ideal for premium home theaters or productivity. UHBR20 (80Gbps): Enables uncompressed 8K/120Hz or dual 4K/144Hz setups, suitable for high-end gaming and professional workflows. The LG 27GX790A-B monitor features a DisplayPort 2.1 bandwidth of UHBR13.5, which is limited to 54 Gbps. This bandwidth allows for high-resolution and high-refresh-rate gaming without the need for Display Stream Compression (DSC), but does not mean it's not a "true" DisplayPort 2.1 port. It just supports a different UHBR rate...^Ivan.

Q: QuestionDP2.1 standard on UHBR13.5 or UHBR20? also, does monitor feature BFI? so far way too many conflicting information provided from various LG sources making me question whether preordering was the right choice

Asked 1 year ago by vogam.

• A:Answer Hello there, Vogam. Thank you for reaching out with your detailed question about the LG 27GX790A-B Gaming Monitor. We understand the importance of accurate specifications when considering a purchase. Regarding your question on DisplayPort 2.1: Based on the available information, the DisplayPort 2.1 on this monitor is operating at UHBR13.5 (54Gbps), not UHBR20. The product page had initially indicated a higher bandwidth, but recent details suggest that UHBR13.5 is the correct configuration. As for BFI (Black Frame Insertion), unfortunately, this model does not feature BFI technology. https://www.lg.com/us/monitors/lg-27gx790a-b-gaming-monitor#pdp_specs We understand how conflicting information can be frustrating, and we appreciate your patience as we provide clarification. If you have any other questions or would like further assistance, please feel free to send us a private message on Social Media @LGUSSupport. We’re here to help you make an informed decision!

Q: QuestionI’m noticing vertical banding on this monitor. How do I fix it? I’ve tried a pixel refresh and no luck

Asked 2 months ago by Anonymous.

• A:Answer We regret to read that you are experiencing vertical banding on your LG 27-inch UltraGear™ OLED QHD 1440P 480Hz 0.03ms G-Sync® Compatible DisplayPort 2.1 Gaming Monitor, Model # 27GX790A-B, and sincerely apologize for any inconvenience.

While slight banding is considered normal for OLED technology, severe, persistent lines after using these methods may require an exchange or panel replacement...^Ivan.

Q: QuestionWhich is faster, the DisplayPort or the HDMI port

Asked 9 months ago by joe.

• A:Answer Hi there, Joe. We understand your inquiry about the LG 27GX790A-B monitor's ports. For the best performance, including the maximum refresh rate of 480Hz at QHD resolution (2560 x 1440), you should use the DisplayPort. The HDMI 2.1 ports on this monitor also support high refresh rates, but the DisplayPort connection is typically recommended for achieving the highest performance specifications for gaming.

Q: QuestionDoes this have a KVM switch or feature? If not, does LG offer any 480hz monitors that come with such a feature?

Asked 1 year ago by Guy.

• A:Answer Hi there, thank you for reaching out to us! We understand you're inquiring about the KVM switch feature for the LG 27GX790A-B gaming monitor. This model does not come with a built-in KVM switch.

Q: QuestionHow do I clean it

Asked 4 days ago by Tommy.

• A:Answer You can clean the LG UltraGear™ 27" OLED QHD 480Hz 0.03ms NVIDIA G-SYNC, AMD Freesync™ Premium Pro Gaming Monitor (HDMI x2, DisplayPort, USB) - Black, Model # 27GX790A-B, using the same basic tools you would use for any high-quality LED monitor, but you must exercise extra caution. Because OLED panels feature extremely delicate anti-glare coatings, they are much more sensitive to scratches and harsh chemicals than standard LED/LCD screens. As with any other monitor, regardless of the type, 1. When cleaning the screen, unplug the power cord and gently wipe with a soft cloth (microfiber cloth) in a consistent direction. 2. Be careful not to apply excessive force, as it may cause scratches or discoloration. 3. If there are a lot of fingerprints, blow a breath of steam onto them and wipe them off. (Do not spray water on the screen or wipe it with a wet cloth (it may cause stains on the screen). Use a soft cloth and a spray bottle to spray water 2-4 times on the cloth. Follow the cleaning instructions listed in the user manual when cleaning the product...^Ivan.
