I have a iPad 7th generation and this week I decided to connect it to a keyboard, mouse and monitor. I used Apple's Lightning Digital AV Adapter to connect it to a Lenovo ThinkVision P24h, which is a QHD (2560x1440) display with full USB-C/DisplayPort support. I can connect my Lenovo laptop to this with a single USB-C cable and it powers the laptop, runs the video out, etc.

My experience with the keyboard and mouse on the 7th gen. iPad has been pretty good. But the display is quite lacking. I get that the iPad only mirrors and scales to the external display but the image quality is quite fuzzy and the mouse cursor movement is very laggy (the mouse feels more like the display is running at 30 Hz versus 60 Hz, but the monitor reports it is running at 60 Hz). I did a bit of research and it looks like this is because the Lightning port doesn't have the bandwidth for a full HDMI signal so the iPad hardware encodes the video and the AV adapter decodes and sends the video over the connected HDMI cable.

So my question, for those who may have tried this or something similar, is connecting via USB-C using an iPad Pro better?

1. Does the mouse cursor lag?
2. The video will scale, obviously, but is it fuzzy/blurry like the AV adapter's output?
