Mouse cursor from microscopic view

[timecard]

I've been messing around a bit trying to measure pixel transition times of the windows mouse cursor at a microscopic view and of course this is already limited to DWM/triple buffer and low fps camera, but it's more specifically related to near field signal generation (RFI/EMI), suppression methods (ferrites, toroid, fiilters) and the impacts. Probably won't have too much info right away but others asked that I post it here to see if it would spark ideas and if anyone else wanted to go down this alley with better observational, capture tools and methodology.

Brief detail:
benq 2411z, AMA Off, Blur reduction off, dwm 144fps, 144hz monitor, 1000hz mouse, win10 2009, bottom right corner of screen, cstates disabled, high perf power plan, default nvidia global profile, camera: iphone 6s 240fps (not sure of margin of error), monitor was on for a couple hours so warmed to operating temps and likely above room 21-22C.

During my "ideal" low perceived input delays (low interference)it was about 3-4 frame transitions from pixel to pixel during fluid pixel movement. My definition of pixel to pixel transition: cursor has not yet caused gray to gray*? transition to the nearest pixel to the right and then to the point where the next pixel has rendered it's ideal color (dark/black)

On a similar note I've been analyzing some near field activity related to monitors (still work in progress and will probably be very limited)

It is interesting. Are you experiencing an input lag problem that changes over time (better at night)?
What does it look like when you feel input lag, something changes in dimensions?
Have you tested this in games? (colored pixels in the background of the scope would be more interesting)

I have a big post on overclock.net on the topic in the mice section and have found ways to reduce the impacts on my system although the true cause still remains.. external and inductive coupling interference (RFI/EMI)into signal, shielding and power lines.

Common User Reported Symptoms:
- Mouse and keyboard are both not reporting properly (user perceived inconsistency) making most aspects of gaming requiring significant focus in attempt to compensate/cope to complete basic tasks e.g. mouse micro adjustments (loss of fine movement/granularity)
- Mouse may be fast but keyboard feels delayed/slow (user perceived inconsistency) making it difficult to synchronize kb/mouse actions together.
- Likely some video response time aspect to this since it is the basis for user perceived experience but I don't have high fps camera

Notables
Some mice/keyboard, devices and their cables/shields have higher tolerance to inductive coupling, however when symptoms are reduced/eliminated there is minimal difference in perceived accuracy/performance between each outside of known sensor/firmware implementation flaws, if any.

As for the better day/night, I've done some other basic research in this area it essentially indicates what you may already know, higher in the day and less into the wee hours for different types of fields/activity, each persons environment being different . I live very close by to high powered transmission lines which have notable EMF/EF which cover the entire home although reduce slightly the further I get. I know people that aren't in the same situation as me and have very similar symptoms.
