OnePlus 55 U1S — Complete Buyer & Seller Guide (2026)

Welcome to your ultimate guide for buying or selling a used OnePlus 55 U1S TV in India in 2026. This isn’t just a price list; it’s an actionable handbook designed to help you navigate the second-hand market with confidence, ensuring you get the best deal, whether you’re upgrading or making a smart purchase.

Section 1: Is the OnePlus 55 U1S Still Worth It in 2026?

Launched in mid-2021, the OnePlus 55 U1S was a flagship 4K LED TV for its time, featuring a 55-inch panel with HDR10+, HLG, and Dolby Vision support, powered by Android TV 10. In 2026, it stands at approximately five years old. While it still offers a solid 4K viewing experience with vibrant colours and decent contrast for its class, it’s important to manage expectations. The core technology, a 4K LED panel, remains relevant for most streaming and cable TV consumption. It boasts Chromecast built-in and access to a vast array of apps via the Google Play Store, making it a capable smart TV.

However, by 2026, the U1S will be showing its age in certain aspects. Software updates for Android TV may have officially ceased, meaning you might not receive the latest Android TV versions or security patches, potentially impacting app compatibility over time. Crucially, it lacks advanced HDMI 2.1 features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and 4K@110/120Hz support, which are standard on newer TVs and essential for next-generation console gaming. For casual viewers and streamers looking for a large 4K display on a budget, it’s still a smart buy. But if you’re a serious gamer or demand the absolute latest smart TV features and long-term software support, you might find it somewhat outdated.

Section 3: Seller’s Guide — How to Prepare Your OnePlus 55 U1S

To maximise your sale price and ensure a smooth transaction on platforms like Bids44, meticulous preparation is key.

1. Data/Privacy Wipe:

   • Sign out of all streaming accounts: Open apps like Netflix, Prime Video, YouTube, Disney+ Hotstar, and any other personal accounts, navigate to their respective settings, and sign out.
   • Factory Reset: This is crucial to remove all your personal data, accounts, Wi-Fi passwords, and installed apps.
     • Go to Settings (the gear icon on the home screen).
     • Scroll down and select Device Preferences.
     • Scroll to About.
     • Select Factory reset or Reset.
     • Confirm the reset. The TV will restart and go through the initial setup process as if it were new.

2. Physical Preparation:

   • Cleaning:
     • Screen: Use a soft, dry microfiber cloth to gently wipe the screen. NEVER use liquid cleaners directly on the screen, as they can damage the anti-glare coating or seep into the panel. For stubborn smudges, slightly dampen a corner of the microfiber cloth with distilled water (ensure it’s barely damp, not wet) and then immediately wipe dry with a separate dry section.
     • Body & Bezel: Use a slightly damp cloth (with mild soap solution if needed) to clean the bezels, stand, and back panel. Ensure no liquid enters any ports or vents.
     • Remote Control: Clean the remote thoroughly, especially in the crevices around buttons, using a cotton swab and a small amount of rubbing alcohol.
   • Minor Fixes: Ensure all cables are neatly tied. If the stand is wobbly, tighten its screws. Replace remote batteries if they are dead.
   • Remove External Devices: Disconnect any external devices like Fire Sticks, set-top boxes, soundbars, or USB drives from the HDMI or USB ports.

3. Documentation:

   • Gather any original purchase receipts, warranty cards (even if expired, they add credibility), and the user manual. Having the original invoice proves ownership and purchase date.

4. Photography Tips for Listing:

   • Good Lighting: Take photos in a well-lit room, preferably with natural light. Avoid direct harsh sunlight or dark, shadowy areas.
   • Screen ON: Take photos with the screen ON, displaying bright, colourful content (e.g., a vibrant nature documentary, a cartoon, or a test pattern). This proves the screen is functional and helps buyers identify any potential issues like dead pixels or backlight problems.
   • All Accessories: Include clear photos of the original remote control, power cable, TV stand, and if you have it, the wall mount bracket.
   • Angles: Capture the TV from various angles – front, side profiles, back (showing ports), and close-ups of the bezel and stand.
   • Model Number: Take a clear photo of the sticker on the back of the TV that shows the model number (OnePlus 55 U1S) and serial number.
   • Clarity: Ensure photos are sharp and in focus.

Section 4: Buyer’s Guide — What to Check Before Buying

A thorough inspection is crucial to avoid costly surprises. Bring a pen drive with test videos and a known-good HDMI cable.

1. Screen Integrity (Most Critical):

   • Dead Pixel Test: Play full-screen solid colour videos (red, green, blue, white, black) from your pen drive or YouTube (“dead pixel test 4K”). Look closely for tiny dots that are stuck on a specific colour, always off (dead), or always on (hot pixel). These are generally irreparable.
   • Backlight Uniformity/Bleeding: Display a pure black screen (YouTube “black screen test 4K”) in a dark room. Look for uneven light patches or excessive light leaking from the edges or corners. Some minor bleed is normal for LED panels, but severe bleeding indicates panel degradation.
   • Clouding/DSE (Dirty Screen Effect): Display a solid grey or white screen. Look for dark, cloudy patches or blotches, especially when panning the camera in a video. This indicates inconsistencies in the backlight or panel.
   • No Burn-in (for LED): The OnePlus 55 U1S uses an LED panel, so permanent burn-in (ghost images) is not a concern, unlike OLED TVs. Focus on the above screen uniformity checks instead.
   • Physical Cracks: Run your finger gently along the edges of the screen bezel. Hairline cracks in the panel might not be visible when the screen is lit, but can cause permanent damage.

2. Port Functionality:

   • HDMI Ports: Bring your own HDMI cable and a device (e.g., a laptop or Fire Stick). Test ALL HDMI ports by plugging in your device and verifying video and audio output. Some
