Review on 🖥️ Smraza 5 Inch Touch Screen: High-Definition 800x480 IPS-TFT Display, Compatible with Raspberry Pi 4B 3B+ 3B by Anthony Record

First, it's a DSI display. It is connected to the Raspberry Pi with a thin 15-wire cable (2 of which are included in the scope of delivery). It doesn't accept HDMI input and only works with Raspberry Pi. On the other hand, you only need one cable - no need to connect separate cables for HDMI, power and USB (for the touchscreen). Drivers are also not needed. There is also a small error in the description. The display is 800x480, not 800x400. It's also much smaller than the photo by hand. When you clench your fist, it covers more than half of the screen. It is 5 inches diagonal (display area only), 4 1/4 inches wide and 2 5/8 inches high. The resolution and connection method is exactly the same as the official Raspberry Pi 7" TFT display, which explains why no drivers are needed. . This display is smaller than the official one, but has an IPS panel that offers better color reproduction and offers better viewing angles. Okay, let's get to the installation. The hardest part is removing the plastic protective layer from the acrylic pieces. Don't cut your nails immediately beforehand, you'll regret it. The assembly instructions consist of 4 photos. They're pretty self-explanatory, except that they don't describe how to install a DSI cable nor describe how to turn on the fan.For every set of screws or rivets there is exactly 1 extra item which I think is very nice.They are tiny and can easily fall and get lost If you've never installed a CSI cable (for a Raspberry Pi camera) or a DSI cable, you might want to watch YouTube vid look up. But in short, you want to pull out the black part of the connector a little (it only comes out about 1/16 inch, so don't strain), insert the cable with the silver part toward the black side (without touching it). , press it until only a small part of the silver part is visible, then press the black clip to fix it. Do this on both the display and the Raspberry Pi. To power the fan, you can connect the fan wires to the two pins on the display labeled "ONLY FAN", if present. Black goes to GND and Red to 3.3V which is no surprise.Alternatively you can connect them to the GPIO pins and software control the fan speed depending on CPU temperature.Search google guides if this is the way to go, you want to hammer in. The fan is pretty weak, so don't rely on it for much cooling of the Raspberry Pi processor. Once connected, power on the Raspberry Pi and it should just work. If it doesn't If that's the case, make sure you have a newer version of the software. Download the official build of Raspbian if you're not sure. I don't have my Raspberry Pi 4 on an LCD mont ed because it's in a pretty nice case. I verified this by simply connecting DVI. A long DSI cable is sufficient for this. I'll get another Pi 4 later to install on the LCD. Because I'm booting into the console and not the GUI, the small display is hard to read. I changed the font size from 8x16 to 12x24 using raspi-config. The display is nice and sharp and there's a button on top to turn it on and off as well as adjust the brightness. Each press increases the brightness slightly until it reaches maximum brightness, and the next press returns to minimum brightness. Overall a good kit, more detailed instructions could be used but not difficult to understand. I think it's best not to use it as a monitor since it's quite small for that, but as a dedicated display. For example, you can set it up to show the weather and check the news. It could even be a smart photo frame - although the tiny size isn't great for that. What this isn't good for is a portable system, as there's no case to protect the electronics. Update: I bought another Raspberry Pi 4 and installed it on the back of the display. Some notes: 1. A short DSI cable can be used, but its installation is a bit complicated. Be patient and everything will be fine.2. If you are using a short DSI cable, insert the microSD card BEFORE plugging in the cable. Alternatively, use tweezers to position the microSD card in place and then push it in.3. Installing the stands that attach to the Raspberry Pi is difficult if you don't have the right tools. One trick I've found is to put the stand in the hole first, then use the included Phillips screwdriver to poke it into the screw hole at the top of the stand and quickly flip it over. Due to the friction, the post rotates a little and gradually settles almost completely. Tightening the screw when installing the fan will fully screw it in. You can try wrapping some tape around the tip of a screwdriver to increase friction.
