To change HDMI on LG TV in hotel, press the Input or Source button on the remote, then select the HDMI port you need. If that button is missing or disabled, press the Home button and choose the Source tile from the on-screen dashboard.
How to change HDMI on LG TV in hotel: the fast way
The quickest method is using the remote that came with the TV. Look for a button labeled Input or Source; it may also show a small TV icon. Press it once, and a menu appears listing every available input, HDMI 1, HDMI 2, and so on. Use the arrow keys to highlight the port your device is connected to, then press OK or Enter. The TV switches immediately.
If the remote has a Home button, press it instead. On the Home screen, find the tile called Source or Input. Select it, then pick the HDMI port you want. This works on most LG TVs that have not been locked down by the hotel. The goal is to reach the list of HDMI ports on a TV and pick the right one without digging through deep menus.
Change HDMI without the hotel remote
If the remote is missing, dead, or disabled, use the physical buttons on the TV itself. On most LG hotel TVs, the buttons are on the bottom edge under the LG logo or on the bottom-right rear side. Older models often have a dedicated Input button. Press it to cycle through sources until you reach the correct HDMI port.
Newer models may not have a labeled Input button. Instead, a quick-press of the Power button opens an on-screen menu. Use the volume or channel buttons to navigate that menu, find the Input or Source option, and select it. A joystick-style button, one that you push up, down, left, or right, can also control the menu. Press the center to confirm your choice.
Bypass Hotel Mode to unlock HDMI inputs
Hotel TVs often run in a special mode called Hotel Mode, Commercial Mode, or Hospitality Mode. This mode restricts access to settings and can lock every HDMI port. To bypass it, try holding down the Settings button (the cog icon) on the remote until the on-screen menu disappears, then enter a service-menu code if you have one, and press OK.
You are now in the service menu. Navigate to the Hotel Mode settings and look for an option to disable Hotel Mode Operation. If that option is not visible, look in the settings menu for a Safety section and check for Input Locks. Toggle the locks off for the HDMI port you want to use. The TV will now accept that input without reverting to the hotel channel.
Use default PINs and alternative codes for input locks
Some TVs ask for a PIN before they let you change inputs or enter the service menu. The most common default PIN is 0000. If that does not work, other codes are sometimes reported online, but they vary by model and may not work. These codes vary by model, so test them one at a time. Once you enter the correct PIN, you can unlock the HDMI port and switch to your device.
Unplug the data cable to regain control
Many hotel TVs connect to a central system through a data cable, either Ethernet or coaxial. This cable carries the hotel channel guide and remote commands. Unplugging it can break the hotel control link and restore normal TV functions. Gently disconnect the cable from the TV or from the breakout box (the small box the cables plug into). Then power cycle the TV: turn it off, unplug it from the wall, wait a few seconds, and plug it back in.
Warning: Unplugging cables in a hotel room may trigger an alarm or result in fines, depending on hotel policy. Only do this if you are certain the hotel allows it, and be ready to reconnect everything before checkout.
Troubleshooting: no signal and device recognition
If you select the correct HDMI input but see a No Signal message, first check that the HDMI cable is fully inserted into both the TV and your device. Make sure your laptop, streaming stick, or game console is powered on. A common mistake is pressing the Picture Mode button instead of the Input button, those buttons look similar on some remotes.
Do not assume the TV will auto-switch when you turn on a device. That feature is unreliable, especially on hotel TVs. If you have tried every method and the LG TV keeps switching from HDMI back to TV, the hotel may have a persistent lock that you cannot override. In that case, contact the front desk and ask if they can unlock the HDMI port or provide a different remote.
