Hello there, Larz. Thank you for sharing your experience with us. We understand your inquiry regarding the OLED55B4PUA 55″ Class B4 Series OLED 4K UHD Smart webOS TV (2024) and the depth dimensions for a flush wall-mount installation. The TV’s “Product Depth Without Stand” is specified as 1.8″ (approximately 4.57 cm) from the rear panel to the front of the display betterhomebydesign.com Best Buy . In other words, the entire back surface of the panel is uniformly 1.8″ thick—there is no thinner bezel section that transitions into a thicker central bulge; the depth remains consistent across the width of the unit. Therefore, the distance from the very thin edge of the screen to the full 1.8″ depth is effectively zero, as the face of the panel itself sits within that 1.8″ thickness. Given that you have a 45″-wide opening, the 48.3″ width of the TV will overlap slightly on each side of your hole. To achieve a flush look, you can: Verify Wall Cutout & Clearance: Use a tape measure to double-check that your 45″ opening will accommodate the 48.3″ panel—this will require a slight extension of the opening or an overlay trim so that the TV’s thin profile (1.8″ depth) sits as close to flush as possible with your existing wall surface. betterhomebydesign.com Confirm VESA Mount & Stud Placement: The OLED55B4PUA supports a VESA 300 × 200 mm bracket. Before hanging, ensure your wall studs are aligned to support the weight (31.5 lb without stand) and that the mount bracket sits flush against your wall framing. Check Clearance for Cables & Ventilation: Even though the panel is 1.8″ deep, allow at least ½″–1″ more behind the TV to accommodate HDMI, power, or optical cables without adding bulk. This also ensures proper airflow so heat can dissipate, preventing any stress on the panel. As a first troubleshooting step, if you find that the TV does not sit flush because of cable connectors or wall-mount bracket depth, try using low-profile, right-angle HDMI and power cables. These slim cables will tuck neatly behind the panel, minimizing any gap between the TV and the wall. https://www.bestbuy.com/site/lg-55-class-b4-series-oled-4k-uhd-smart-webos-tv-2024/6578057.p?skuId=6578057 If you have further questions about installation, measurements, or need assistance with compatible wall-mount brackets, please send us a private message on Social Media @LGUSSupport.
