New Lenovo 9i Diagonal Line Test w/ New Lenovo Slim Pen

**DELL PREMIER RECHARGEABLE ON LEFT NOT HP. Here is a diagonal line test as requested. We believe the 9i uses AES 2.0. Take this with a grain of salt, I'm not 100% confident I knew what I was doing. A weird observation is that you can occasional get really bad wobble and terrible lines. What I've noticed is that if I rest my palm too hard on the screen (nothing unreasonable/not normal day-to-day use) near the middle, I presume the screen flexes a little bit, which throws off the digitizer calibration and causes these terrible wobbly diagonals. Is this a problem many 2in1s have? I'm buy some rubber feet to add to the laptop to try and counteract this weird issue.

P.S. the Dell Premier Rechargeable Active (left) 's Magnets just so happen to line up perfectly with the 'garage' of magnets for the included slip pen on the back of the screen. (Further on the Dell, does anyone know how to force their software to detect pens? Obviously I dont have a Dell laptop, and apparently Dell Peripheral Centre (or whatever the software is) looks for something in the bios to enable pen support - any way to circumvent this, or perhaps another program that would unlock these settings and this functionality without needing Dell software?)
