I use my iPad for English lessons due to the poor quality of the camera on my PC.
こんにちは!
ご質問ありがとうございます。
ご質問について、いくつか言い方が考えられますが、例えば、
I use my iPad for English lessons due to the poor quality of the camera on my PC.
として、『私のPCのカメラのクオリティが悪いので英語のレッスンにはiPadを使います。』とするのはいかがでしょうか。
また、
The built-in camera on my computer makes me look older and produces poor image quality that I'm not satisfied with. So, I bought an external camera and attached it to my PC. However, even with the external camera, it captures me in a vertically stretched manner, which is quite frustrating. Despite the challenges with screen sharing and other activities, I still prefer using my iPad for English lessons because it captures me in a cute and presentable way.
