Hello,
Today I wrote a simple Microsoft Windows opengl 3.0 application for inspect ing frame numbers, frames per second.
I was wondering if maybe monitors drop frames like internet packets, maybe as a way to cheat. So far I also recorded some high speed camera footage wi th powershot hs sx50 or whatever, which can shoot 250 fps per second.
The application is here, which displays a white increasing number, one incr ement per frame, it's v-synched and all, so it should be able to adept to w hatever the frame rate is set of the monitor/video card refresh rate and su ch:
Multiple download options:

I recommend installing a graphics card driver before attemping to run it. A lso it is not multi-threaded and it simply uses the main thread of Delphi's VCL, sometimes this might lockup or something on my laptop, not sure why, this app might require administrator level access to be able to run, not su re, just try a couple of times if you have any troubles starting it, make s ure to terminate it later if it doesn't run properly. I haven't isolated th e source of this problem yet if it occurs, usually after bootup of laptop.
Anyway here is also some camera footage of toshiba laptop and also a fujit su-siemens monitor:
I hope to be buying a new PC soon which will ofcourse require a new monitor as well. The last PC I bought was 14 years ago ! Holyfuck !
I am very much interested in monitor quality !
So if you happen to have a high speed video camera like mine and you believ e you have a top monitor then do a little test, run this frame counter appl ication and then record it, put the video somewhere on the internet and sen d me a reply in this forum or via e-mail: skybuck2000 at hotmail dot com.
And I will look at your video ! Hopefully it's not infected with a video vi rus ! ;) =D
I am curious to the gray to gray times. I have also noticed red to green to blue times and a struggle for this particular cheap monitor which was boug ht by a priest and given to my MOTHER ! =D
Anyway, maybe I will make another application for that, I kinda already hav e one it's simply displaying random reds and greens and blue pixels at thei r maximum intensity and then simply scroll it, which ofcourse does require opengl for fast rendering, and this will show the reds greens and blue goin g dark as the screen scrolls ! Which kinda sucks about this futjisue monito r.
So I definetly want something better than that for my next PC ! ;)
Meanwhile I will continue using my mother's laptop, a toshiba from 2012.
It's also in one of the videos and it's quite bright and does manage to ren der the numbers quite well... I do notice some rasterization as the screen scrolls in another app I wrote... that's kinda strange. It's like the color s have grids inside of them... like square boxes of all kinds of colors.
Perhaps more on that later.
Perhaps I will write a more thorough monitor testing tools.
Because there are so many weaknesses in all kinds of monitor display techno logy, most of which only become apperent when viewing at a certain angle, o r when actually scrolling 2D graphics or when certain patterns are displaye d even stationary, yes there is a lot of weaknesses in all kinds of monitor s and special test sites on the internet.
Not yet sure if I will be able to develop all tests maybe, maybe not.
But for now I am kinda interested in the things I noticed myself in day 2 d ay practice/operation ! ;)
Bye for now, Skybuck:
P.S.1: Enjoy another great release from Skybuck Flying ! LOL.
P.S.2: I made that font myself ! ;) =D
P.S.3: O, In case you were wondering both monitors did NOT drop any frame s :) (Except when I move the application around, that frame is caused becaus e the application freezes when moving it around the screen ! ;)) Though the fujitsue monitor does seem to struggle to catch up with the fram es, and barely makes it, I kinda noticed this in another app, where scrolli ng seems very shaky !
P.S.4: The laptop does seem to blur the screen when it scrolls, another app will have to be used for that ! ;) (It does look nicer/more smooth then th e other monitor)
