<br />
== Summary ==<br />
The 8DP-CAPLCD is an 8-inch IPS display with capacitive touch and HDMI input. It can be used as a PC monitor or a Raspberry Pi display, connected via USB for touch and HDMI for video, powered by 5V Type-C.<br />

<br />
== Technical overview ==<br />
* Resolution 1280×800 at 60 Hz; 8-inch diagonal; viewing angle 178°.<br />
* 10-point capacitive touch with toughened glass (up to 6H hardness) and optical bonding.<br />
* Ports: HDMI input, USB for touch, 5V Type-C power, 3.5mm headphone jack, and 4PIN speaker header.<br />
* Supported systems: Raspberry Pi OS, Ubuntu, Kali, Retropie, and Windows 11/10/8.1/8/7.<br />
* Input current must be at least 750 mA at 5 V; nominal 800 mA; operating temperature 0–60 °C, storage -10–70 °C.<br />
* Max brightness 400 cd/m², contrast 1200:1, color gamut 62% NTSC, power draw about 4 W, weight 406 g.<br />
* EDID values for manual setup: pixel clock 77 MHz, H/V addressable 1280/800, blanking 232/56, front porch 160/20, sync width 32/6.<br />
* For Raspberry Pi, the resolution must be set manually in config.txt; otherwise the display may show incorrectly.<br />

'''Commands and examples – verify before use:''' <br />

hdmi_group=2<br />
hdmi_mode=87<br />

<br />
== Notes and version constraints ==<br />
* The exact config.txt commands apply only when the system does not auto-detect EDID; board versions (V1/V2) differ in solder pads for PWM backlight control.<br />
* If USB power is insufficient, the display flickers; connect an external 5 V / 1 A adapter to the Power port.<br />
* Current below 750 mA can cause startup failures or permanent damage; voltage above 5.25 V can permanently damage the device.<br />
* Avoid long-term storage in high temperature/humidity; operating outside specified temperatures can damage the display.<br />
* Windows touch calibration requires tapping on screen; if the screen is blank, press Enter to switch the prompt to the touchscreen.<br />
* PWM backlight control requires soldering to specific pads that differ by board version – verify the correct version before soldering.<br />
