 ## Required hardware
 Pi-KVM supports several different hardware configurations, referred to as **platforms**. Now available: **v2** and **v0**.
-* **v2** is the recommended and most modern implementation for **Raspberry Pi 4** and **ZeroW** supporting all of the features of Pi-KVM including the **Mass Storage Drive**. **It's also the easiest to make**
+* **Recommended**: **v2** is the most modern implementation for **Raspberry Pi 4** and **ZeroW** supporting all of the features of Pi-KVM including the **Mass Storage Drive**. **It's also the easiest to make**
 * v0 was designed to work with Raspberry Pi 2 and 3 that do not have OTG and requires a few more components for a basic implementation. It also does not support the Mass Storage Drive feature.

+  #### A few words about HDMI-USB dongle
+  It's completely supported and Pi-KVM works great with it. But it has some disadvantages compared with recommended [HDMI-CSI bridge](https://aliexpress.ru/item/4000102166176.html): USB gives a lot of latency (200ms vs 100ms) and it doesn't support stream compression control (you won't be able to use Pi-KVM in a place with a poor internet connection). It also cannot automatically detect screen resolution. All this is caused by the hardware limitations of the dongle itself. In addition, some users report hardware problems: the dongle may not work in the BIOS or simply stop working after a while. It's a black box, and no one knows what's inside it. If you have problems with it, it will not be possible to fix them.

-It's completely supported and Pi-KVM works great with it. However, we recommend to use [HDMI-CSI bridge](https://aliexpress.ru/item/4000102166176.html) because the USB dongle has several major disadvantages compared to it: USB gives a lot of latency (200ms vs 100ms) and it doesn't support stream compression control (you won't be able to use Pi-KVM in a place with a poor internet connection).

 #### Addition
 * If you want to capture VGA from your server instead of HDMI, buy the [VGA-to-HDMI converter](https://aliexpress.ru/item/4000553298530.html).
 * Pi-KVM can be powered using PoE, but it is not recommend to use the official PoE HAT: it is unreliable and [not compatible with the HDMI bridge](https://github.com/pikvm/pikvm/issues/6). Use any other PoE hat without an I2C fan controller.
