I've had an HP Spectre x360 Convertable-15 df1xxx (core i7 10th gen, nvidia, 4k screen) for over a year now. I really like it. Running Linux Mint MATE currently on 19.3 MATE 1.22.2. I was able to adjust the display for Hi DPI -- can't remember what I did exactly but I have Appearance > Fonts > Details > Resolution DPI (dots per inch) set to 192.

Great keyboard (with full numeric keypad). I went into the keyboard settings and adjust some compatibility options so I could shift-arrow using the num pad to select text.

Wifi just worked. I bought a USB ethernet dongle that works fine also.

Mouse USB plug causes hang on hard boot -- just unplug it when booting. I mostly use sleep which works fine. Mouse movement wakes from sleep - but I was able to disable this:

  mxv@mvhp:~/bin$ cat disable_mouse_wakeup.sh 
  sudo cp /home/mxvanzant/.wakeup/wakeup /sys/bus/usb/devices/1-1/power/wakeup
  mxv@mvhp:~/bin$ cat /home/mxvanzant/.wakeup/wakeup 
  disabled

I don't use an external monitor, but this has HDMI which I've used on occasion.

Weight and size are not bad (for me), but you might prefer lighter laptops..
