Buying Guide & Pre-Sales Questions
What do I need for setup and operation?
You only need a TV or monitor with a free HDMI port, an internet connection (via WiFi or the integrated LAN port), and a free Google account. An HDMI cable is already included.
Which apps can I use & are there additional costs?
The GX1 provides access to the official Google Play Store with thousands of apps optimized for TV. These include Netflix, Prime Video, Disney+, Apple TV+, YouTube, and many more.
There are no monthly costs for using the box itself. You only pay the subscriptions of the respective streaming providers (e.g., Netflix) if you want to use them.

What is the advantage over a cheap streaming stick?
The GX1 is designed for maximum performance and longevity. Unlike basic sticks, it offers:
- More storage: 32GB internal storage (instead of often just 8GB) and 4GB RAM for dozens of apps without constant warnings.
- Ports: An integrated 100 Mbps LAN port for stable 4K streaming, two USB ports for external hard drives, and an optical audio output.
- High-end chipset: A powerful Realtek processor that keeps the system running smoothly even years from now.
What are the benefits of the AI features (AIPQ & AISR)?
The Realtek chip analyzes the video image in real-time. AIPQ (Artificial Intelligence Picture Quality) dynamically optimizes contrasts and colors to make the picture more vivid. AISR (Super Resolution) intelligently upscales lower-resolution content (e.g., standard HD TV or older series) to 4K, smoothing edges and making the picture significantly sharper.
Does the GX1 support external hard drives?
Yes, you can connect external USB hard drives to play your own media. For very large hard drives (e.g., 4TB or more), however, we recommend using a model with its own power supply to ensure continuously stable operation. Important: If you use hard drives with large movie files formatted in NTFS or exFAT, please read the corresponding note in the "Troubleshooting & Knowledge Base" section below for smooth playback.
Troubleshooting & Knowledge Base
Help with settings and technical problems. Solutions directly from our technicians.
Prime Video shows an HDMI connection error
The device is not defective. This error occurs if the digital copy protection (HDCP) between the TV and the GX1 is not negotiated quickly enough. Prime Video is very strict about this.
- Original cable: You must use the included HDMI cable (HDCP 2.2 capable).
- Handshake reset: Disconnect the TV and GX1 completely from the power supply. Unplug the HDMI cable, plug it back in, and restart.
Tip for LG TVs: Go to the LG settings and temporarily disable HDMI Deep Color (or Ultra HD Deep Colour) for this HDMI input. This usually resolves the conflict.
Picture looks overexposed (bright faces) / pixelated background
This is an incompatibility with the HDR signal or color space. The TV interprets the picture data incorrectly for a moment.
Solution in the GX1 menu:
- Go to Settings → Display & Sound → Resolution
- Change HDR setting from "Always HDR" to "Adaptive" (or test "SDR").
- Change Color Space from "Auto" to "RGB" or "YCbCr 4:2:0".
- Restart the device.
Note for premium TVs (e.g., Metz, Sony, LG): Make sure the HDMI port in the TV menu is set to "Enhanced Format" or "UHD Color".
Picture freezes on Live TV apps, audio continues
This often occurs with European IPTV apps (Cosmote, Eon TV). They send a fixed 50Hz signal. If the GX1 is set to 60Hz, the decoder goes out of sync.
Force the system to 50Hz:
- Go to Settings → Display & Sound → Resolution
- Disable auto-switch.
- Manually select 4K 50Hz (or 1080p 50Hz) and restart.
Picture stutters during movies (Judder / double contours)
Movies usually run at 24p (frames per second). If the GX1 is set to 60Hz, the TV has to display frames twice, which leads to "skipping" during camera pans.
Enable automatic matching:
- Go to Settings → Display & Sound → Resolution
- Enable Match Content Frame Rate.
- Set the value to Always.
Kodi / Plex: Do I have to change the frame rate manually?
No. Modern media players have their own automatic matching integrated.
Setting in Kodi:
Go to Settings → Player → Videos and set "Adjust display refresh rate" to On start / stop. Kodi will then automatically force the TV into the judder-free 24p mode.
Go to Settings → Player → Videos and set "Adjust display refresh rate" to On start / stop. Kodi will then automatically force the TV into the judder-free 24p mode.
The GX1 turns on by itself
This is mostly caused by the "HDMI-CEC" control. Your TV or receiver accidentally sends a wake-up signal to the box.
How to disable this:
- Go to Settings → Display & Sound → HDMI-CEC
- Turn off the CEC Switch or Auto Wake options.
Remote constantly reports new updates on the TV
These are not real software updates. It is a typical sign of slight voltage fluctuations in the batteries (connection drop and re-pairing).
Solution: Replace the batteries with new, branded batteries. The message will then disappear immediately.
The front LED is too bright. Can it be turned off?
Yes, this is easily possible. Just use the pre-installed "LedControl" app, which you can find in the app menu. There you can completely disable the status LED of the box.
Why are apps like NordVPN pre-installed on my new device?
You don't need to worry: You are guaranteed to receive brand new and original sealed goods. The fact that certain apps like NordVPN, YouTube, or Netflix are already on the system is technically completely normal and not a sign of a returned item.
These are official partner apps that were permanently integrated into the firmware by the manufacturer of the operating system (Google TV) at the factory. The device is in its absolute original condition.
One of the USB ports does not recognize my flash drive, mouse, or hard drive. Is the port defective?
No, this is not a hardware defect. Under Google TV 14, the box features smart power management: if no device is plugged into a USB port when the box powers on, the system automatically puts that port into sleep mode. Because the remote control only places the box into light standby, the port often remains inactive when plugging in a device later.
1. Cold boot with the device plugged in: Unplug the power cable from the back of the box. Plug your USB device into the port first, and then reconnect the power cable. The system will now detect and permanently activate the port during startup.
2. Check plug insertion depth: Due to the housing design, one of the USB ports sits about one millimeter deeper inside the casing. If your flash drive has a wide plastic casing, make sure to push the plug firmly all the way in.
3. External hard drives (500 mA limit): Both USB 2.0 ports provide a standard maximum current of 500 mA (ideal for flash drives, mice, and keyboards). External 2.5-inch mechanical hard drives without their own power supply often require up to 1000 mA to spin up. Please use a powered USB hub when connecting external hard drives.
4. Accessing files on Google TV: Unlike a PC, Google TV does not display an automatic pop-up window when a storage drive is inserted. Simply download a free media player or file manager app from the Google Play Store (such as VLC, Nova Video Player, or X-plore) to view and play your files.
USB hard drive is not recognized or the system prompts for formatting
By default, the Google TV operating system only recognizes storage devices in the FAT32 format. If you have large movies on a hard drive formatted in NTFS or exFAT, the system will incorrectly prompt you to format it when plugged in. Please do not format the hard drive, otherwise your data will be lost!
Powerful media player apps like VLC for Android or Kodi come with their own drive drivers. If you download these apps for free from the Play Store and open them, they can directly read your NTFS or exFAT hard drive. You can easily play your videos without the main Google system needing to mount the stick or hard drive natively.

If the drive is also missing in VLC/Kodi:
If your hard drive does not even appear in the list within the specialized apps mentioned above, this is clear evidence of an insufficient power supply. Mechanical hard drives require a very high starting current to set the physical disks inside in motion. The compact design of the GX1 technically does not allow such high power peaks to be delivered via the USB port.
The simple solution: Use a powered USB hub (a USB splitter with its own power adapter for the wall outlet). Connect your hard drive to this hub. Its power supply now provides the required power for the drive, while the GX1 only processes the data. In this combination, even large NTFS hard drives are recognized immediately and run absolutely stably.
