Got a vantage pro, display isnt bright enough

I bought a nice used unit, well taken care of, and updated to 16.4. The display is best under low light conditions. I did some searching of pics, and found the same thing, just not a very brite screen. Even the person I bought it from said "yep, they are all like that" . Adjusted the brightness and contrast, and it looks like all the other images out there.. on the dim side. Such a shame too because Im mobile, and not in shop lit enviroment. Guess I need to find a shaded tree?! My solus ultra is prefect though. Not sure why SO couldnt do better on the VP. I swapped the coloring to a black back round which seems to help a bit. But even still............

I find the same outside, the verus also gets alot of glare in the sunshine, the few times we get it he in the UK.

I've had a Modis, Solus Pro and Verus and they all suck in the sun...
The Verus is better than the other two, but only just so.

My Owon Labscope is the same even on just bright day.
