at 4km (2.5 mi), you should be able to see your target. If you cannot the signal is low because you are shooting through an obstruction. Unless there is some other circumstance like the antenna you are adjusting is atop a 20ft pole to see over the neighbors roof.
Now that you have a signal, I would watch the screen you are on in the screenshot, it updates quick enough, then rotate the dishes as little as possible each way left and right, till you get about -56. You may need to do this at both ends at least 2 times to get a perfect alignment.
Normally I would use a 23dbi panel for this distance, cheaper and easier to aim in 5 minutes.
Also take the advice of getting r52 or cm9, or at least turn down your tx power by automatic and put in the 29dbi antenna in the wireless screen.
Your signal should be around -63 with only 17db of gain.
To getting a stronger signal will improve ccq.
Noise reduction: change channels or polarity, -103 is good but there may be bursts of noise that affect your signal reaching.
Diffraction. Raise your dishes up as much as possible. Sometimes even 1 ft can clean up your fresnel to acceptable levels.
