Regarding, "...am leaning more toward the -F because of the IPS display being (much?) more visible outdoors (in bright light)."
Although it is cloudy so I cannot do the experiment in sunlight just now and I appear to have the model with better contrast anyway, but when I use polarized sun glasses I can turn the nanoVNA 90 degrees from normal and get improved contrast.
Try it when you get the chance.
Hope this helps,

Doug,
The display of the NanoVNA-H4 is better than the early model NanoVNA-H. It is slightly smaller than the NanoVNA-F (4" vs 4.3") and also has less screen resolution. The actual character size of the value readouts is about the same, because the NanoVNA-F uses up some of the screen with additional vertical scaling.
More to your point, the NanoVNA-F has no brightness control and cannot be adjusted for different viewing conditions. The brightness of the NanoVNA-H4 is adjustable and at its maximum level is brighter than the NanoVNA-F and more visible in sunlight. The attached photo shows both units under the same strong sunlight condition. The graticule lines of the NanoVNA-H4 display are not as washed out.
So yes, the NanoVNA-F's display has higher resolution, but it is only brighter if the NanoVNA-H4's brightness is not set to maximum. On a really sunny day either unit will probably have you squinting at the screen.
