I got a new laptop last August. Acer Nitro 5. I found if I want anything 
that is beyond the basic and is not a business machine, it has to be a 
gaming laptop.


I use it mainly for development.

I do not watch MythTV with it, preferring a TV with fire stick. It has 
NVidia graphics. It runs MythTV and supports VDPAU and NVDEC with 
MythTV. The built in screen is 1080 15.6 inch and the ubuntu display 
allows refresh rates of 60 and 120. I don't know if something can be 
done to support 50. Externally you can attach a 4K screen and I use that 
regularly for development.

There is one Linux glitch, and I have a workaround. When suspending 
several times a day, about once a week it locks up solid with a crash in 
the NVidia drivers. It is reported on Ubuntu, but my workaround has 
completely prevented it.
