Unfortunately the Pi4 changed to USB-C power chord, but as you know, I must put the power chord first into the touchscreen display which than outputs the power via GPIO outputs to the Raspberry.
If I still use the old micro usb power adapter, the Pi4 does not get enough power. It boots and runs so far, but shows the little lightning symbol on the screen. Then I bought the new 3A USB C official power adapter and tried to connect it to the screen with a micro usb to usb c adapter. Unfortunately the Pi does not get any power at all with the usb c power supply and the micro usb adapter.
Is there any (official) 3A power adapter available with micro usb instead of usb c for this setup: pi4 and touchscreen? If not, is there any appropiate solution for my problem?
I am currently using the Raspberry pi 4 with the official touchscreen. I can confirm that the official USB C charger is more than enough to power the Pi and the touchscreen. I"ve had LOTS of problems getting the lightning bolt (under-voltage warning) with the touchscreen on a 3b+ but have not yet seen it on my Pi 4. I did have the thermometer (cpu temp warning) come up on the pi 4 but have since modified my touchscreen case to include a small fan and added heatsinks to the pi. Hope this helps
I"m planning to upgrade to a pi4 and will be using a hat that means I don"t have access to the gpio. Can you confirm that it is possible to power the touchscreen by using a USB cable from the pi"s usb-a port to the touchscreen"s micro-usb power port?
See image below for what jumper configuration looks like. Only Red and Black jumpers are being used. Using only the USB-C power connection on the Rasbperry Pi 4 to run both screen and pi.

I"m powering my Pi 4 Model B through the X400 sound card HAT which unfortunately doesn"t have the GPIO pins, I"ve tried powering the official touchscreen from the pi"s USB ports but that doesn"t seem to work (works fine with a separate power adapter though). Is it just not possible to power the touchscreen from one of the pi"s usb ports? I would prefer not have to solder cables onto the HAT"s GPIO.
My SmartiPi V2 case came with that cable and a Pi 4 version that is USC C in to USB C (Pi 4B) and Micro USB (touch screen). I haven"t seen that cable for sale separately. So you"d have to make one with the old cable and an adapter for the Pi 4B. Assuming the 2.5A Micro USB supply is enough to drive both.
So it looks like this configuration is powering the Pi4 from the USB-C connection (which is good), and the screen off of the jumper pins. I read somewhere that the 5v GPIO connection is very low current isn"t the screen drawing too much power to be run of the GPIO pins? Or does the Pi4 supply a lot more current than previous models?

A computer monitor is an output device that displays information in pictorial or text form. A monitor usually comprises a visual display, some circuitry, a casing, and a power supply. The display device in modern monitors is typically a thin-film-transistor liquid-crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Previous monitors used a cathode-ray tube (CRT) and some plasma (also called gas-plasma) displays. Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, USB-C, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.
Originally, computer monitors were used for data processing while television sets were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4:3 to 16:10, to 16:9.
Modern computer monitors are easily interchangeable with conventional television sets and vice versa. However, as many computer monitors do not include integrated speakers nor TV Tuners (such as digital television adapters), it may not be possible to use a computer monitor as a TV set without external components.
Early electronic computers were fitted with a panel of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.
Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.
The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the system in a single large chassis. The display was monochromatic and far less sharp and detailed than on a modern flat-panel monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for the specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.
By the end of the 1980s color CRT monitors that could clearly display 1024 × 768 pixels were widely available and increasingly affordable. During the following decade, maximum display resolutions gradually increased and prices continued to fall. CRT technology remained dominant in the Personal computer(PC) monitor market into the new millennium partly because it was cheaper to produce and offered to view angles close to 180°.
There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.
The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined over a period of years they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140
High dynamic range (HDR)television series, motion pictures and video games transitioning to high-definition (HD), which makes standard-width monitors unable to display them correctly as they either stretch or crop HD content. These types of monitors may also display it in the proper width, by filling the extra space at the top and bottom of the image with a solid color ("letterboxing"). Other advantages of widescreen monitors over standard-width monitors is that they make work more productive by displaying more of a user"s documents and images, and allow displaying toolbars with documents. They also have a larger viewing area, with a typical widescreen monitor having a 16:9 aspect ratio, compared to the 4:3 aspect ratio of a typical standard-width monitor.
Organic light-emitting diode (OLED) monitors provide higher contrast, better color reproduction and viewing angles than LCDs but they require more power when displaying documents with white or bright backgrounds and have a severe problem known as burn-in, just like CRTs. They are less common than LCD monitors and are often more expensive.
Radius of curvature (for curved monitors) - is the radius that a circle would have if it had the same curvature as the display. This value is typically given in millimeters, but expressed with the letter "R" instead of a unit (for example, a display with "3800R curvature" has a 3800mm radius of curvature.
Color depth - measured in bits per primary color or bits for all colors. Those with 10bpc (bits per channel) or more can display more shades of color (approximately 1 billion shades) than traditional 8bpc monitors (approximately 16.8 million shades or colors), and can do so more precisely without having to resort to dithering.
On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the case or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.
The size of a display is usually by monitor manufacturers given by the diagonal, i.e. the distance between two opposite screen corners. This method of measurement is inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, it was the external diameter of the glass envelope that described their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangular image was smaller than the diameter of the tube"s face (due to the thickness of the glass). This method continued even when cathode-ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3.
The estimation of the monitor size by the distance between opposite corners does not take into account the display aspect ratio, so that for example a 16:9 21-inch (53 cm) widescreen display has less area, than a 21-inch (53 cm) 4:3 screen. The 4:3 screen has dimensions of 16.8 in × 12.6 in (43 cm × 32 cm) and area 211 sq in (1,360 cm2), while the widescreen is 18.3 in × 10.3 in (46 cm × 26 cm), 188 sq in (1,210 cm2).
Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition was productive uses for such monitors, i.e. besides widescreen computer game play and movie viewing, are the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and CAD application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.
In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."
The resolution for computer monitors has increased over time. From 320 × 200 during the early 1980s, to 1024 × 768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920 × 1080.2560 × 1600 at 30 in (76 cm), excluding Apple products and CRT monitors. Apple introduced 2880 × 1800 with Retina MacBook Pro at 15.4 in (39 cm) on June 12, 2012, and introduced a 5120 × 2880 Retina iMac at 27 in (69 cm) on October 16, 2014. By 2015 most major display manufacturers had released 3840 × 2160 resolution displays.
Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor"s service life. Some monitors will also switch themselves off after a time period on standby.
Most modern laptops provide a method of screen dimming after periods of inactivity or when the battery is in use. This extends battery life and reduces wear.
Most modern monitors have two different indicator light colors wherein if video-input signal was detected, the indicator light is green and when the monitor is in power-saving mode, the screen is black and the indicator light is orange. Some monitors have different indicator light colors and some monitors have blinking indicator light when in power-saving mode.
Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows Interface drivers and other small software which help in proper functioning of these functions.
These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.
Some displays, especially newer LCD monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are very visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only mitigates the effect.
Newer monitors are able to display a different image for each eye, often with the help of special glasses, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.
A combination of a monitor with a graphics tablet. Such devices are typically unresponsive to touch without the use of one or more special tools" pressure. Newer models however are now able to detect touch from any pressure and often have the ability to detect tilt and rotation as well.
A desktop monitor is typically provided with a stand from the manufacturer which lifts the monitor up to a more ergonomic viewing height. The stand may be attached to the monitor using a proprietary method or may use, or be adaptable to, a Video Electronics Standards Association, VESA, standard mount. Using a VESA standard mount allows the monitor to be used with an after-market stand once the original stand is removed. Stands may be fixed or offer a variety of features such as height adjustment, horizontal swivel, and landscape or portrait screen orientation.
The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as a VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel monitors, TVs, and other displays to stands or wall mounts.
