The LG OLED evo C4 television is available in the following screen sizes: 83", 77", 65", 55", 48", and 42". This makes the C4 series one of the most versatile ranges among LG OLED TVs.
1) Product lineup and availability may vary by country or region. Please refer to your local LG website for the latest information.
How to install an LG OLED evo C4 TV on the wall?
For a secure and seamless wall installation of your LG OLED evo C4 TV, please follow these guidelines:
Compatible Wall Mount Brackets & VESA Sizes¹
∙ 83” model: WB21E or WB24GC (VESA 180×55 / 400×400)
∙ 77”, 65”, 55”, 48”, 42” models: OLW480 (VESA 300×200)
Installation Steps
1. Ensure the wall has sufficient strength and load-bearing capacity for your TV and bracket.²
2. Mark and drill holes according to the VESA pattern and the instructions provided in the Quick Setup Guide and Owner’s Manual.
3. Attach the bracket securely to the wall using appropriate anchors and screws.
4. Connect all required cables before mounting the TV for easier access.
5. Carefully mount the TV onto the bracket.
Professional installation is strongly recommended by LG to ensure safety, optimal alignment, and to protect your TV—especially for larger screen sizes.
Note:
LG provides clearly illustrated, multilingual installation guides with the product and online. Always refer to the correct guide for your TV model and screen size.³
1) *Please check the exact VESA pattern and compatible bracket for your specific model and screen size. The wall-mount bracket and included accessories may vary by model and region. Please check your product package and the local LG website for details. If the bracket is not included in your package, ensure that you use a compatible bracket with the exact VESA pattern for your specific model and screen size.
2) *The strength and suitability of the installation wall and anchors are the responsibility of the customer. LG is not liable for damage or injury caused by improper installation or insufficient wall strength.
3) *Installation procedures and supported accessories may differ depending on your country, TV size, and model year. Always follow the instructions in the official LG Owner’s Manual and Quick Setup Guide for your specific product.
What is the LG OLED evo TV screen protection, and how can it work?
LG OLED evo TVs are equipped with screen protection features to help prevent image retention and reduce the risk of burn-in. The key technology is Pixel Cleaning, which refreshes the OLED pixels to maintain optimal picture quality and panel longevity.
Automatic Operation: Pixel Cleaning runs automatically after a certain period of accumulated usage, usually when the TV is turned off but remains plugged in.¹
Manual Operation: You can also manually start Pixel Cleaning at any time by navigating to:
[Settings] → [General] → [OLED Care] → [OLED Panel Care] → [Pixel Cleaning] on your TV’s menu.
These features help keep your OLED panel in the best condition for long-term use.
1) Pixel Cleaning reduces, but does not eliminate, the risk of permanent image retention (“burn-in”). For best results, avoid displaying static images for extended periods. Always leave the TV plugged in after turning it off to allow the automatic Pixel Cleaning to complete.
How many HDMI ports does the LG OLED evo C4 TV have and what features do they support?
The LG OLED evo C4 TV is equipped with four HDMI 2.1 ports. These ports support a full range of advanced features for gaming and connectivity:
- Variable Refresh Rate (VRR) up to 144Hz for all sizes (83", 77", 65", 55", 48", 42").¹
- G-SYNC and AMD FreeSync Premium compatibility.
- Auto Low Latency Mode (ALLM) for optimized gaming responsiveness.
- Quick Media Switching (QMS).
- Enhanced Audio Return Channel (eARC) on HDMI 2 for high-quality audio transmission.
- HGiG for HDR gaming.
All four HDMI ports support HDMI 2.1 bandwidth (48Gbps), enabling the latest gaming consoles, PCs, and home theatre equipment to be connected simultaneously.
1) Maximum VRR is up to 144Hz for all C4 sizes (83", 77", 65", 55", 48", 42"). Please refer to your local LG website for full model specifications.
