LCD compatibility and content management
Confirm the LCD’s HDMI input, required resolution, rotation and audio connection before installation. This page does not promise HDMI capture or a 4K output mode for the supplied box. The previous RK3399 description was inconsistent with the model-specific manufacturer document.
Choose Wi-Fi, USB or TF-card updates for local content delivery, or LAN/Internet access for managing connected screens. Record the installed Android and firmware versions before software changes, and confirm any optional hardware with the order.
Retained product images
Original images are retained. Use the confirmed model label and interface specification to identify the supplied configuration.


Frequently asked questions
Is the HD-40S-BOX an RK3399 player?
No. The manufacturer’s HD-40S-BOX V1.3 document specifies Allwinner A40i. The previous RK3399 and 4K/HDMI-input description did not match this model and should not be used to select it.
What does the 1+32 configuration mean?
V1.3 specifies 1 GB RAM and 32 GB storage as the standard configuration. Confirm this configuration on the supplied unit, especially when replacing an older player.
Can I update content without a wired PC connection?
Yes. The manual documents Wi-Fi, USB-drive and TF-card updates, as well as LAN and Internet management. Confirm the compatible software and content workflow for the installed firmware.
Does the original PDF describe the same model?
The retained download is labeled HD-40B internally, despite the old link text referring to 40S-BOX. It is identified below as a legacy reference; do not use its processor, storage or display claims as proof of this product’s configuration.
How can I request the current price?
Send EagerLED the HD-40S-BOX model, required 1 GB + 32 GB configuration, quantity, LCD input/timing and delivery destination. Ask for confirmation of the supplied hardware and accessories with the quotation.
