The automatic startup of LG TVs on an HDMI source is not enabled by default, despite the widespread use of connected devices. Many users are unaware that internal settings and recent HDMI standards allow for this behavior to be automated, provided a few unintuitive steps are taken.
The compatibility between LG TVs, audio systems, and media boxes relies on technical protocols that are often poorly utilized. HDMI ARC, eARC, and CEC offer opportunities for simplification, but their configuration remains obscure for most. Mastering these standards transforms daily use and optimizes home comfort.

Why choosing a direct startup on HDMI transforms the use of your LG TV
Setting your LG TV to turn on directly to the HDMI port changes the game on a daily basis. From the first power-up, the device immediately displays your favorite console, box, or player, without going through a cascade of interfaces. No more blindly navigating the webOS menu: access to content becomes immediate, without detours.
The HDMI CEC technology, which LG calls SimpLink, makes all the difference. Once activated, it allows the external device to wake the TV and take control of the HDMI port as soon as it powers on. Gone are the days of juggling remote controls: everything is managed from a single point, smoothly. This option has been available for several generations of LG TVs but remains underutilized, often due to ignorance or fear of tampering with settings.

A lesser-known tool, hotel mode, can go even further. It allows you to select the default HDMI source at startup, without any additional manipulation. Turning on the LG TV directly to HDMI then ceases to be a tip reserved for insiders: the function becomes accessible, without tinkering or headaches. Just a few minutes are enough to transform the user experience, provided you dare to explore the advanced settings.
In households where multiple devices share the TV, the automatic selection of the priority HDMI streamlines the ecosystem. No more conflicts between consoles, boxes, or players: each device finds its place, and the user regains control over their own usage, without spending time juggling settings.
How to easily configure your LG TV to turn on directly to the HDMI source
The configuration can be done in a few steps, accessible on most LG TVs equipped with webOS. Start by going to the Settings using the remote control. Once in the menu, go to the General section, then look for the HDMI-CEC option (which LG calls SimpLink). Activate it: this allows any compatible device, box, console, or player to assert itself as the main source at startup.
Be sure to use a high-speed or ultra high-speed HDMI cable. This precaution, sometimes overlooked, affects the stability of the signal and the synchronization of commands between devices. An unsuitable cable can cause interruptions, slowdowns, or detection failures.
Activating hotel mode: an additional automation
For compatible LG TVs, hotel mode allows you to select a default HDMI source without daily manipulation. Here’s how to access this hidden function:
- Press the “Menu” button on the remote control.
- Enter a specific key combination (usually “1 1 0 5” followed by “OK”, but there may be variations depending on the version of the internal software).
- In the menu that appears, choose the HDMI port to use by default at startup.
Remember to regularly check for firmware updates in the TV settings. Software updates often bring new options or improve compatibility with recent devices.
A meticulous setting, a suitable cable, a well-thought-out activation: every detail counts to ensure that the LG TV starts up on the correct HDMI source every time, without unpleasant surprises.
HDMI ARC, eARC, and CEC: understanding the differences and leveraging each feature
The abbreviation HDMI now encompasses much more than just image transmission. LG TVs, generation after generation, have integrated technologies that profoundly change sound management and coordination between connected devices. Three terms frequently arise: ARC, eARC, CEC. Each has its specialty, but the subtleties of usage deserve clarification.
HDMI ARC (Audio Return Channel) simplifies audio transmission: the TV can send sound directly to a soundbar or home theater receiver using the same HDMI cable as for the image. No need for an additional optical cable. ARC supports most common audio formats, such as Dolby Digital and DTS, but shows its limits when the streams become more demanding.
HDMI eARC (enhanced Audio Return Channel), compatible with HDMI 2.1 ports, marks a qualitative leap. It accepts uncompressed audio streams: Dolby Atmos, DTS Master Audio. The result: sound that matches the quality of 4K or HDR images, without loss and without delay. The living room takes on the atmosphere of a cinema.
Finally, HDMI CEC (Consumer Electronics Control) allows for centralized management: a single remote controls both the TV, the soundbar, and the players. On LG TVs, simply activating SimpLink allows for the automatic powering on of the HDMI source of your choice while ensuring smooth communication between the various compatible devices.
Activating and understanding these options means exploiting all the capabilities of each HDMI port, improving sound reproduction, and simplifying the digital life of the household. A well-oiled mechanism, where each device finds its place and where the user remains in control.
