Hi Maria

Adding an SSD will help speed things up, but I looked up the specs for your PC and it looks like it is getting a little old (AMD dual-core 1.4 GHz processor?).
I would recommend purchasing a new PC with an SSD drive, 8 GB of RAM and a decent processor (ideally an i7-8550U or i5-7200U)
For notebooks, personally I like the Dell XPS series, although the camera placement is bad if you care about that...

Hi Maria

>and that maybe the ethernet port would increase the speed of my internet connection?

Yes, that is correct. However, if you always use wireless, then you can ignore this issue.

>Point n.2: what do you mean by "does not fully support high-resolution screens". Do you refer to the quality/speed/or what?

A picture is worth a thousand words. Notice in the below screenshot how the buttons and table are cut off.
"does not fully support high-resolution" means that you will see these UI issues.
However, it is still usable and does not affect speed. 

Hi Maria

The solution would be to buy a notebook with 1920x1080 HD resolution.
However, I know SDL has working on solving this problem, so it could be fixed in another update.

Hi Maria Rosaria Venosa, Hi Jesse Good,

I have a very useful little Win10 notebook with 1920x1080 resolution screen, which I use for working on the move. I also have a very large 1920x1080 resolution screen for my Win10 desktop PC. They both display Studio beautifully.

All the best,

Alison

>Yes, Evzen, you're right - with 100% scaling no problems at all.
Unfortunately Alison, 100% has problems on 13 inch notebooks. The icons just become too small to work with.

Also, as Evzen points out this is very common on small notebooks these days. (Personally I find the screen image to be sharper, but the software has to support it...)
