A:AnswerHi there. Thank you for reaching out to us. We understand your inquiry regarding the screensaver settings on your OLED77C4PUA.
On webOS 24, the traditional screensaver has been largely integrated into the Always Ready feature, or is managed under System settings. Here is how you can adjust these options:
To set a custom Screensaver (Wallpaper/Art/Clock):
- Go to Settings (Gear icon) > General > Always Ready.
- Toggle Enable the Function to ON.
- Here you can select your preferred mode: Art Piece (for paintings), Movements (videos), Moments (your photos), or Clock.
- This feature will display your chosen content when you press the power button (entering standby) or after a period of inactivity if configured.
To adjust Screensaver Timer or Promotions:
- Go to Settings > General > System.
- Select Additional Settings > Screen Saver Settings.[4]
- Here you may adjust the Screen Saver Standby Time or toggle Screen Saver Promotion (ads) On/Off.
Note: The automatic "Fireworks" screensaver is a built-in protection feature for OLED displays to prevent image retention and may automatically activate if "Always Ready" is not used.

Model # OLED77C4PUA, is a 2024 model so some Best Buy locations may still have it in stock while other locations may not.

A:AnswerWe regret to read about the issues you are experiencing with the 77" Class C4 Series OLED evo 4K UHD Smart webOS TV (2024), Model # OLED77C4PUA, and sincerely apologize for any inconveniences.
You can try deleting then reinstalling the YouTube or Peacock apps to see if that resolves the the hanging up issues.
The TV can be reset without having to unplug it by pressing and holding the power button on the TV's control panel for 5 to 10 seconds. This method is a quick fix and does not require any additional steps or tools.
Another method is to press the power button and the volume button on the remote control simultaneously for 10 to 15 seconds. Try both the volume up or the volume down buttons.
Pressing and holding the physical power button on the TV then unplugging the TV while doing so, and continuing to hold the power button and plugging the TV back in and hold the power button from at least 10 more seconds is similar to doing a factory reset but without deleting your apps or personal settings...^Ivan.

A:AnswerHi there, Rick! Thank you for your question about the LG OLED77C4PUA TV!
This model is designed and supported for horizontal (landscape) orientation only. Using it in portrait mode is not recommended, as it could affect internal ventilation, image quality, and may void the warranty.
If you’re looking for a display that can be mounted in portrait orientation, we recommend checking out LG’s commercial signage displays, which are built specifically for that use.

A:AnswerHello there! We understand your situation wanting to know how the LG OLED C4 (2024) differs from the LG OLED C1 (2021), and we’re here to break down the key upgrades:
Picture Processor & Upscaling
C1: α9 Gen 4 AI Processor 4K
C4: α9 AI Processor 4K Gen 7, with enhanced AI Super Upscaling and Dynamic Tone Mapping Pro for more accurate color, contrast, and detail.
Brightness & Color Volume
C1: Standard OLED peak brightness (~750 nits).
C4: Brightness Booster with over 1000 nits peak in HDR and 100% color volume, delivering punchier highlights and deeper color accuracy straight out of the box.
Refresh Rate & Gaming Features
C1: 120 Hz native refresh rate, VRR, ALLM, G‑Sync
C4: 120 Hz native + support up to 144 Hz, improved Game Optimizer, FreeSync™, and Auto Low Latency Mode for a smoother gaming experience.
Smart Platform & Connectivity
C1: webOS 6.0, basic AI Sound Pro
C4: webOS 24 with built‑in Matter, AI Concierge, Always Ready mode, Room‑to‑Room Share, and enhanced voice control via Magic Remote – plus USB Camera compatibility.
Design & Mounting
C1: VESA 400 × 200 mm
C4: VESA 300 × 200 mm
Both maintain the near‑bezel‑less OLED look, but the C4’s slimmer panel tech and updated stand design offer a slightly sleeker profile.
Troubleshooting step:
To ensure you’re experiencing all these improvements, make sure your C4’s firmware is up to date—go to Settings > All Settings > General > About This TV > Check for Updates before you dive into those new features.

A:AnswerHi there. We appreciate your interest in the LG OLED77C4PUA 77” OLED evo C4 Series TV and understand your need to find a suitable stand for it.
For this specific model, we recommend using a TV stand that is at least as wide as the TV’s stand width of 20.5 inches to ensure proper support and stability. However, for aesthetic balance and added safety—especially if there are kids or pets around—a stand with a width closer to or greater than the full TV width of 67.4 inches is highly suggested. This provides extra space and helps avoid tipping hazards.
The TV dimensions with the stand are 67.4" (W) x 40.7" (H) x 10.5" (D), so you’ll want to make sure your furniture can accommodate this footprint as well.
If you plan to use a soundbar or other AV components, consider choosing a wider media console to fit everything comfortably without crowding the base of the TV.

A:AnswerHi there, Dudley. We understand how important it is to have consistent access to your favorite content on Paramount Plus with your LG OLED77C4PUA. Since the Taylor Sheridan Collection is sometimes available but not always, we recommend the following steps:
Check for App Updates – Ensure that Paramount Plus is running the latest version. You can update it via the LG Content Store.
Restart the TV – Power cycle your TV by unplugging it for about 60 seconds, then plug it back in and turn it on.
Clear Cache – Go to Settings > General > System > Application Manager, select Paramount Plus, and clear the cache.
Check Your Internet Connection – A stable internet speed of at least 25 Mbps is recommended for smooth streaming in 4K HDR.
Reinstall the App – If the issue persists, uninstall and reinstall Paramount Plus to refresh the app.
https://www.lg.com/us/tvs/lg-oled77c4pua-oled-4k-tv#pdp_specs
If the issue continues, it may be related to regional content availability or Paramount Plus servers. Feel free to send us a private message on @LGUSSupport, and we’d be happy to assist further! —Renzo
