![]() ![]() It should be noted that most of the support channels are only accessible during regular business hours. If you do run into issues, Acer has a great customer service system and can be contacted via email, phone and on their website. For one thing, all the buttons are on the side of the screen, rather than the top, which means that you won’t accidentally press them while using the touch screen. If comfort is your primary concern with a touch screen monitor, then the Acer T232HL is easily our top pick of the available options thanks to some intelligent design choices. ![]() The Acer T232HL can tip back 80 degrees, so it’s easy and comfortable to use. You can also mount the Acer T232HL on the wall with standard VESA mount. There are also in-built speakers and an audio jack to let you connect a headset to the monitor. It has two HDMI ports, a VGA port for those with older connections and several USB 3.0 ports. The ports and sockets were all easy to access. We found that the Acer T232HL was incredibly easy to set up and start using. ![]() Some users on Amazon have noted that the screen is quite reflective and can be difficult to use without a screen filter, but the Acer T232HL has received generally positive reviews on the site with an average star rating of 4 stars out of five. Ultimately, we didn’t feel it impacted our experience with the Acer T232HL much at all. If color accuracy is hugely important to you, we recommend checking out the Planar Helium PCT2235. ![]() This is disappointing, but we’re talking relatively minor deviations here - a picture of a rose will show up a slightly lighter shade of red, but it’s not suddenly going to turn yellow. What we mean by this is that images on screen don’t always look the color they should do. The only real issue we have with the Acer T232HL is the color accuracy, especially when the screen is viewed from an angle other than straight on. The on-screen keyboard takes up a lot of room on the Acer T232HL’s display. We were able to use all of the functions of the screen - like dragging, pinching, and rotating - without any problems. If you’re buying a touch screen monitor, the very least you’d expect is that the touch screen works as advertised and we’re happy to say it does. It has a 60 Hz refresh rate and a 5 milliseconds response time, so you won’t have any issues with the screen updates lagging behind your movements when you’re using it. It’s tough to find a dedicated touch screen monitor that goes above this resolution though, so users looking for 4K screens will likely have to give up on the touch screen dream (or buy a laptop with a 4K screen, at great expense). The Acer T232HL has a 1920 x 1080 pixel resolution, aka full HD, which is essentially the baseline standard for monitors these days. You can adjust the screen angle anywhere between 30 and 80 degrees, which means you can keep the screen upright like a standard monitor or lay it down almost flat in front of you - a feature that makes the Acer T232HL ideal for digital artists who want to draw directly onto the screen. That's a generous take on the design, however, but it is very practical. It can be a blessing in disguise though, as it gives you something to grab when you need to readjust the screen angle. There is a fairly chunky 1.25-inch bezel around the entire screen, which looks quite ugly now that we’re used to edgeless touch screens on many of the best smartphones. I don't know if the new Pi 3 B+ has a different USB behaviour.The Acer T232HL has a 10-point multi-touch screen. I have tested this with a Pi 2 and a Pi 3. But you have to connect it to the two "normal" USB ports, not the USB dedicated charging port (I know it sounds strange, but it seems that connecting the power to that port and the upstream USB port, the one used for USB data, causes some kind of power cycle on the charging port). If you enable USB charging while off on the screen, the Raspberry Pi can be powered by the screen. It is shown in dmesg as a device that fails to enumerate. If it is 2.0 (or 3.0 despite it will be recognized as 2.0), the screen USB hub (manufactured by Via) will be recognized, but no USB 1.1 devices connected to that hub will work (the internal touchscreen controller is 1.1). I know that this is a very old thread, but, since it's one of the first results if you look for this monitor and Raspberry Pi on Google, I'll post the solution I found.įor the touch to work, the USB hub between the monitor USB port and the Raspberry has to be USB 1.1. ![]()
