Understanding the TVs: Design and Mounting Considerations
The LG C3 and Samsung S90C are both marvels of display technology, boasting stunning OLED panels. While they share many similarities in picture quality and overall slimness, there are subtle differences in their design that can impact your mounting choices. Understanding these nuances will help you select the best wall mount and ensure a seamless installation. We’ll break down what makes them unique and how that affects mounting.
LG C3: Slim Bezel, Center Stand Design
The LG C3 is renowned for its incredibly thin bezels and a design that prioritizes a clean, minimalist look. When it comes to mounting, this often means the VESA mounting holes are strategically placed towards the bottom center of the TV’s rear panel. This placement is common for many LG OLEDs and is designed to keep the TV flush against the wall when using a compatible mount. The slim profile means minimal clearance is needed, which is great for aesthetics but also requires a mount that can accommodate this. Always double-check the VESA pattern specification for your exact C3 model size. For example, a typical 65-inch LG C3 uses a 300x200mm VESA pattern, but this can vary slightly by size and generation.
Samsung S90C: One Connect Box and Panel Design
The Samsung S90C, while also exceptionally thin, introduces the One Connect Box system. This means that all your cable connections are routed to a separate box, which can then connect to the TV with a single, slim cable. This is a huge win for cable management and aesthetics! However, it’s important to note that the mounting itself is still direct to the TV panel. The S90C also features VESA mounting holes, typically located towards the bottom of the TV. Similar to the C3, the exact VESA pattern will depend on the screen size. A 65-inch S90C might use a 400x300mm VESA pattern, so confirming this is crucial before purchasing a mount. The slim design still holds true, and a well-chosen mount will keep it close to the wall.
Key Differences in Mounting Hardware
While both TVs are designed for wall mounting, a few key differences might influence your choice:
- VESA Patterns: As mentioned, always verify the specific VESA pattern (e.g., 300x200mm, 400x300mm) for your exact TV model and size. This is the most critical piece of information.
- Cable Management: The S90C’s One Connect Box simplifies cable routing to the box, but you’ll still need to manage the single cable from the box to your devices and then potentially a power cable to the TV. The C3’s cables connect directly to the TV, requiring management behind the screen.
- Mount Types: Both can accommodate standard wall mounts (fixed, tilting, full-motion). However, the ultra-slim nature of these TVs means you might lean towards low-profile or slim mounts to take full advantage of their design.
Choosing the Right Wall Mount: A Detailed Look

Selecting the correct wall mount is the most crucial step for a secure and satisfying installation. It’s not just about holding the TV up; it’s about ensuring safety, optimal viewing angles, and a clean look. We’ll cover the different types of mounts and what to look for.
Types of Wall Mounts Explained
There are three primary types of wall mounts, each offering different functionalities:
- Fixed Mounts: These are the simplest and most basic mounts. They hold the TV flat against the wall, with very little space between the TV and the wall. They offer the slimmest profile but no adjustability. They are excellent for dedicated home theater rooms where the viewing position is fixed.
- Tilting Mounts: These mounts allow you to angle the TV up or down. This is useful if you need to mount the TV higher on the wall than ideal for direct viewing, such as above a fireplace. They offer a bit more flexibility than fixed mounts while still keeping the TV relatively close to the wall.
- Full-Motion (Articulating) Mounts: These are the most versatile. They allow you to tilt, swivel, and extend the TV away from the wall. This is perfect for rooms where you’ll be watching from various angles or seating positions. They offer the greatest flexibility but can leave a bit more space between the TV and the wall when fully extended.
Essential Features to Consider
When browsing for your mount, keep these features in mind:
- VESA Compatibility: This is non-negotiable. Ensure the mount explicitly states it supports the VESA pattern of your LG C3 or Samsung S90C. You can usually find this information in your TV’s manual or on the manufacturer’s website. For example, a common VESA pattern for larger OLEDs is 400×400 mm, but double-check.
- Weight Capacity: Your mount must be rated to safely support more than your TV’s weight. OLED TVs are surprisingly light for their size, but it’s always best to have a buffer. Consult your TV’s manual for its exact weight.
- Screen Size Compatibility: While VESA is key, mounts are also often rated for a range of screen sizes. Ensure your 55-inch, 65-inch, or 77-inch TV falls within the mount’s specified range.
- Low-Profile Design: For OLEDs, which are designed to look sleek and thin, a low-profile mount is often preferred. This minimizes the gap between the TV and the wall, enhancing the aesthetic.
- Cable Management Features: Look for mounts with built-in cable channels or ties to keep your wires neat and hidden. This is especially beneficial for the clutter that can arise from multiple HDMI and power cords.
- Ease of Installation: Some mounts are designed for simpler DIY installation than others. Read reviews to gauge the difficulty.
Recommended Mount Brands and Where to Buy
Reputable brands often provide a good balance of quality, safety, and features. Some popular and reliable options include:
- Sanus: Known for sturdy construction and innovative features, Sanus offers a wide range of mounts for various TV types.
- Kanto: Kanto mounts are often praised for their build quality and ease of installation, with options for fixed, tilting, and full-motion needs.
- Wali: Wali provides more budget-friendly options that still meet VESA and weight requirements, making them a good choice for those on a tighter budget.

Tools and Materials You’ll Need
Before you begin, gather all your tools and materials. Having everything ready will make the installation process smoother and safer.
Essential Tools
- Stud Finder: Crucial for locating wall studs, which provide the necessary support for the mount.
- Drill and Drill Bits: You’ll need these to pre-drill holes for the lag bolts and potentially for mounting the bracket to the TV.
- Level: Ensures your mount and TV are perfectly horizontal and plumb.
- Screwdriver Set (Phillips and Flathead): For attaching the TV bracket to the TV and for other minor adjustments.
- Socket Wrench or Ratchet Set: For tightening lag bolts securely into the wall studs.
- Measuring Tape: For precise placement of the mount.
- Pencil: For marking drill points.
- Safety Glasses: Protect your eyes from dust and debris.
- Optional: Painter’s Tape: Can be useful for marking and guiding your drill, and for masking surfaces.
Mounting Hardware (Typically Included with Mount)
Most wall mounts come with a kit of hardware. However, it’s good to be aware of what to expect:
- Lag Bolts: These are the heavy-duty screws that anchor the wall plate to the studs.
- Washers: Used with lag bolts to distribute pressure.
- Spacer Blocks/Standoffs: Sometimes included to create a small gap between the TV and the wall or mount, particularly useful for cable clearance.
- Various Screws (M4, M6, M8 sizes): These are used to attach the TV bracket arms to the back of your TV. Your TV’s manual will specify which size to use.
- Cable Ties or Clips: To help manage wires behind the TV.
Important Note on Wall Types
This guide primarily focuses on mounting into wall studs in drywall. Mounting into other wall types like concrete, brick, or plaster requires different hardware and techniques. For instance, mounting into concrete would require masonry drill bits and appropriate anchor bolts. If you are not mounting into studs, it is crucial to use anchors rated for the weight of your TV and the mount. For example, Toggle-Tite bolts or similar heavy-duty anchors can be used if stud mounting isn’t possible, but always ensure they meet the weight requirements. Always consult a professional if you are unsure about your wall structure. Resources like the U.S. Green Building Council offer insights into building materials that can help you understand your home’s structure.
Step-by-Step Mounting Guide for LG C3 / Samsung S90C

Let’s get your TV mounted! Follow these steps carefully for a secure and professional-looking installation.
Step 1: Plan Your TV Placement
Decide exactly where you want your TV to go. Consider:
- Viewing Height: The center of the screen should generally be at eye level when you’re seated.
- Glare: Position the TV to minimize glare from windows or lights.
- Outlet Access: Ensure you have access to power and cable/HDMI outlets.
- Stud Location: The mount needs to attach to at least two wall studs for maximum support. Studs are typically 16 or 24 inches apart.
Step 2: Locate Wall Studs
Use your stud finder to locate the center of at least two wall studs in your chosen mounting area. Mark the edges of the studs with a pencil, then find and mark the center line of each stud where you plan to install the mount. You can confirm stud location by gently tapping or by drilling a very small pilot hole.
Step 3: Mount the Wall Plate
Hold the wall plate of your mount against the wall, aligning it with your stud marks. Use your level to ensure it’s perfectly straight. Mark the lag bolt hole locations on the wall. Pre-drill pilot holes at these marks. The pilot hole should be slightly smaller than the lag bolt diameter. Then, attach the wall plate securely using the lag bolts and washers, tightening them firmly into the studs with your socket wrench. Do NOT overtighten, as this can strip the stud.
Step 4: Attach Brackets to the TV
Lay your LG C3 or Samsung S90C face down on a soft, protected surface (like a blanket or the original packaging foam). Locate the VESA mounting holes on the back of the TV. Attach the vertical brackets from your mount to the TV using the appropriate screws provided with the mount. Ensure you use the correct screw length and diameter as specified by your TV’s manual. If your TV came with standoffs or spacers, use them now if needed for cable clearance or to ensure a flush fit.
Step 5: Hang the TV on the Wall Plate
This step often requires two people, especially for larger TVs, to prevent dropping or damaging the TV. Carefully lift the TV and align the brackets on the back of the TV with the wall plate. Most mounts have a hook or rail system that allows the brackets to hang securely onto the wall plate. Once hung, engage any locking mechanisms (screws, clips) that secure the TV to the wall plate. This is critical for safety!
Step 6: Connect Cables and Manage Wires
Now, connect your HDMI cables, power cord, and any other necessary connections to your TV. For the Samsung S90C, connect your source devices to the One Connect Box. Use the cable management features of your mount (clips, ties, channels) to tidy up the wires. You can also use adhesive cable clips or a cable management sleeve for a cleaner look.
Step 7: Final Adjustments and Check
If you have a tilting or full-motion mount, make any necessary viewing angle adjustments. Gently test the mount’s articulation. Ensure the TV is stable and securely fastened. Double-check that all locking mechanisms are engaged. Step back and admire your work!
Troubleshooting Common Mounting Issues
Even with careful planning, you might encounter a few bumps along the way. Here’s how to handle them:
- Mount Isn’t Level: If the wall plate is slightly off, loosen the lag bolts slightly, adjust with your level, and re-tighten. If it’s significantly off, you may need to drill new holes. Ensure you fill old holes to maintain wall integrity.
- TV Feels Loose: This is a safety concern! Re-check that all screws are tight, especially the locking screws that secure the TV to the wall plate. Ensure you used the correct screws for the TV and that they are fully engaged. If still loose, you may have used the wrong mounting holes on the TV or the mount itself might be faulty.
- Lag Bolts Won’t Tighten or Spin: This often means you’ve stripped the stud or the hole is too large. You might need to use a slightly larger lag bolt or a wooden dowel and wood glue to fill the hole and re-drill. Consult resources like This Old House for detailed repair techniques.
- TV Doesn’t Sit Flush: Some TVs have slight curves or protruding components on the back. Use any included spacers or standoffs to create clearance. Ensure you haven’t overtightened TV bracket screws, which can stress the panel.
