- A: AnswerHello there. Congratulations on your new LG OLED77B4PUA TV, and thank you for reaching out with your question. We understand how important it is to ensure your TV will fit perfectly on your console. The OLED77B4PUA has a central stand design, meaning the legs are positioned more towards the middle rather than at the edges. The distance between the legs is approximately 47.2 inches. Since your TV console is 60 inches, the TV should fit comfortably with some space on either side. If you have any further questions or need additional assistance, please don’t hesitate to send us a private message on social media @LGUSSupport. We’re here to ensure your setup is just right. —Renzo

Q: QuestionHow long is the power cord for the LG OLED 77" UHD B4?(1 answer)
A: AnswerHi, Hondo. Thank you for reaching out with your question. The power cord for the LG TV (OLED77B4PUA) model, typically measures around 6 feet in length. This should provide a decent amount of flexibility for most installations, but if you need a longer reach, you can always use an appropriate extension cord as long as it's rated for the TV's power requirements. If you have any other questions or need further assistance, feel free to send us a private message on social media @LGUSSupport. Our team will be more than happy to assist you. ^JuvyAnswered by LG Digital Customer Care
- A: AnswerHi there, thank you for your inquiry about the OLED77B4PUA! The distance from the bottom VESA mounting holes to the bottom edge of the TV is approximately 9.8 inches. The IR sensor is located just below the center of the TV’s bottom edge, so the clearance for it would not significantly add to this measurement. If you’re mounting the TV above a console, this measurement should help you achieve a snug and aesthetic setup. For more detailed guidance or additional questions, feel free to send us a private message on Social Media @LGUSSupport. Our team is happy to assist further! —James

OLED77B4PUA
The initial picture quality was incredible! Setup was easy and taken step by step. All was good until in the third week, the screen developed a "ghost line" about 2" wide from top to bottom. You can see the picture through the line. And now, it has a green line in the middle of the ghost line. A few days ago, it developed a second line beside the first. Service is scheduled and I am hoping to get this resolved. Overall, really happy with the TV though!

LG OLED B4
The LG OLED B4 TV was a great purchase. It has super clear clarity and has a better response time than the previous TV I owned. This is a better option than the C4 series considering its $500 cheaper and gives almost the same picture quality.
