Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Is Linux version of NanoSaver better than Windows 10 for screen scaling?

Hi guys,
As I have previously told Sigi, I have an eye problem, and I will eventually need corneal tissue transplants. Using my 4" 2N without a PC is a challenge! Poor visual acuity means I need to scale the Win10 screen by 150% for best viewing on my LG 27" monitor (screen resolution is 1920x1080).

According to my ex-Uni colleagues, the way Win 10 is written causes programmers screen scaling problems. And what I find with NanoSaver - and many other programs - is that parts of the displayed charts are not easily viewable because they are constantly "off the screen". WinQT has no problems displaying on my system, but is less useful for my interests.

My question is: if I built up a Linux system, (I do have spare computers), would this solve my viewing problems? If so what might be the best Linux distribution to use? I have a little Unix experience from many years ago, but have never used Linux before. However, the possibility of a steep learning curve with Linux does not bother me unduly!

Linux should do you just fine. I use Linux Mint 20, and it has accessibility options. I have mine so I hold the Alt key down and use the scroll wheel to zoom in and out. I can move around the screen while it is zoomed out, and I can zoom out to where only one or two words fill the entire screen (or anywhere in between, of course). There really isn't much of a learning curve. Five years ago, after telling my family for years that they should switch to Linux, one of my brothers and one of my sisters finally asked me to install Linux on their computers. I left Windows on their computers so they could boot into either Windows or Linux. I got one support call from each of them, and I recently asked them how many times they had booted into Windows since I had installed Linux for them. Zero. Not even once. My brother recently asked me if I could take Windows off his computer to make more room for photos and such. Try Linux, you'll love it.

Thanks Jim,
It looks like LinuxMint 20 Cinnamon will work on an old student PC (64 bit, 2GB RAM) thrown out by the CompSci techs at the University I recently retired from. Many thanks for the information.
