If Windows Update says your device is up to date, you have all the updates that are currently available. Select the Start button, and then go to Settings > Update & security > Windows Update, and select Check for updates. On the main menu, click Component Tests and System board / USB When the menu appears, press the F2 key. Turn on the computer and immediately press Esc repeatedly, about once every second. Hold the power button for at least five seconds to turn off the computer. Please run a Hardware Diagnostic on the USB ports I have gone through your Post and I appreciate all your efforts This is a great place to get support, find answers and tips.

HP tech support thought it might be a VGA to USB compatiblity issue and that I should download an additional driver - but they didn't know where to find it. Eventually, I'm hoping to have both external displays work - but for now, I'm just trying to get get the display to be recognized through the USB 3c port. For testing purposes, it's the same VGA cord as the one that connectes to the HDMI and works just fine. Nothing was detected and the monitor stayed dark. I purchased a USB 3.1c to VGA adapter and tried to use it with the same VGA cord and same monitors - plugged the VGA cable into the adapter and then in to the 3.1c port, but nothing happened. The laptop has two standard USB ports, an HDMI port and a USB 3.1c port.

Those wanting to learn more can do so via this patch series.I have two external dell monitors and my end goal is to use them as extended displays with my HP laptop.īoth/either monitors work fine with the VGA cord plugged into an HDMI adapter and then plugged into the HDMI port of my HP Pavillion 1KT93UA#ABA laptop. The DRM part of the gadget is placed in the DRM subsystem since it reaches into the DRM internals. lz4 compressed framebuffer data/pixels are sent over the bulk endpoint. The protocol is implemented using control requests. The display is implemented as a vendor type USB interface with one bulk out endpoint. It presents a DRM display device as a USB Display configured through configfs. This adds the gadget side support for the Generic USB Display. The driver is MIT licensed to smooth the path for any BSD port of the driver. It is added in preparation for future monochrome e-ink displays. This is not implemented in the gadget driver. The driver supports a one bit monochrome transfer format: R1. LZ4 compression is used if the device supports it. Optimal user experience is achieved by providing damage reports either by setting FB_DAMAGE_CLIPS on pageflips or calling DRM_IOCTL_MODE_DIRTYFB. If the device transfer buffer can't fit an uncompressed framebuffer update, the update is split up into parts that do fit. Performance is preferred over color depth, so if the device supports RGB565, DRM_CAP_DUMB_PREFERRED_DEPTH will return 16. If both are present, EDID is just passed on to userspace.

There is also support for backlight brightness exposed as a backlight device.ĭisplay modes can be made available to the host driver either as DRM display modes or through EDID. The following DRM properties are supported: The Linux gadget device driver will serve as the canonical device implementation.

This adds a generic USB display driver with the intention that it can be used with future USB interfaced low end displays/adapters. The generic USB display driver patch explains all the interesting technical details: A video embedded below shows the Generic USB display driver in action with different hosts/devices. Performance is obviously a big concern for USB-based displays but even for low-end Raspberry Pi hardware he's been getting some promising results. It would have been nice to have a microcontroller implementation to ensure that I haven't made things unnecessary difficult to implement." I was hoping to have someone working on a microcontroller based USB display by now, but unfortunately that has been delayed. Noralf noted, " The reason for calling it 'Generic' is so anyone can make a USB display/adapter against this driver, all that's needed is to add a USB vid:pid. The Generic USB Display Driver is a generic solution for using the likes of the Raspberry Pi SBCs into converting them into makeshift USB display adapters via a new USB host driver and a device/gadget driver. This driver was written following his idea of turning a Raspberry Pi Zero into a USB to HDMI display adapter. Longtime Linux DRM developer Noralf Trønnes has written a new driver for Linux to serve generic USB display purposes.
