Why do certain programs on my AOC LE22A1321 LED TV display a loss of detail?
- P
  pleachSep 23, 2025
  Certain programs on DVD or other digital sources may display a loss of detail, especially during fast-motion or dark scenes, due to the digital compression of the source content. This compression can cause your TV screen to display less detail than usual, or cause artifacts (small blocks or dots, pixilation) to appear. These effects are more visible depending on the clarity and resolution of the television.

  Keith ShahAug 23, 2025
  If your AOC LED TV's remote control isn't working, try these steps: First, check the polarity of the batteries and replace them with fresh ones if needed. Make sure you are pointing the remote control directly at the remote control sensor located on the front of the TV. Fluorescent lamps can sometimes interfere with remote control operation, so try turning them off. Also, ensure that there are no obstacles blocking the remote control sensor area.

  If your AOC LED TV displays a good picture but you're not hearing any sound, try these steps: First, check the volume control and make sure it's not muted by pressing the MUTE button or VOL +. Ensure that the mute icon disappears from the screen. If you have headphones connected, disconnect them. For devices connected via HDMI, verify that the audio output setting of the connected equipment is set to PCM. Note that this TV's HDMI inputs support PCM 32, 44.1, and 48 kHz.

  To address a noisy picture on your AOC LED TV, ensure that the antenna is connected using a 75-ohm coaxial cable. Keep the antenna cable separated from other connecting cords to minimize interference. For best results, use an undamaged antenna cable to avoid TV interference.

  If your AOC LED TV displays no picture or no signal when connected to a PC, check the following: Confirm that the PC is correctly connected to the TV using either the PC IN (with an HD15 cable) or an HDMI IN connection. Ensure that the output signal from the PC is one of the supported formats. Turn the PC off, verify the connection, and then restart the PC to allow plug and play to auto-detect the TV and correctly set up PC timing. Also, verify that PC Power Management is activated.
