Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

As I can guess or speculate what I want. I have done your ufo test whit four colors, and you can see that at the center of the 30 and 15 fps line, you can see colors of the right ufo. This is the video . What I thing is happenig is that you need two light emitters (horizintally) at the left and two ...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

Ok this can explain the frame mixing at LCDsm, that is a thing I am saing. But I can see the same frame mixing at the CRT and it don't have ghosting or blur. Please try not to confuse this kind of blur with other science. It's important not to guess/speculate, the rest of your post will lead to an ...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

I have done another video. This is the video . I have put one green ufo in one frame a red one at the next and then 4 black frames in cicles. Do you remember that with the LCD moving the head like saying no I didn't see the two colors. Now I see them, and blinking my eyes I also see them. Even with ...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

1. Possible Cause #1: Extremes of the stutter distance (amplitude) I will try to understand this and response you. 2. Possible Cause #2: PWM dimming. Yes it have PWM dimming, but I remember to read at a review that at 100 % brightness it don't have it. So with it at 100% I didn't see the multiple i...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

Thanks for all the info. Yes, I undrerstand that a black frame or a flicker is doing the double image effect and now that MPRT is no causing it. But at the compare frame rates: ufo test , I see a double ufo effect at the 30 fps line at my LCD, do the test have black frame insertion?. I also have a q...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

First of all, that is the wrong paper. That's the motion threshold paper, not the sample-and-hold paper Ok. Thanks thank for saing that it's wrong and the below explanation, I will try to undesrstand it. thanks for the info. I see now that at the Eye Tracking Motion Blur - Optical Ilusion test what...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

Thanks for the info. I see now that at the Eye Tracking Motion Blur - Optical Ilusion test what is conpleting the white line gaps is the motion blur from persistence, I understan right?, it's not explained at the web and the video. So at the CRT tracking the lower ufo the vertival lines are the MPR...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

Perfect then, thats a thing that I didn't know. Thanks for the explanation. Thanks, I will see all the tests and the info and I will try to undesrstand it. I will try to buy a 120Hz or more display, but is something I don't need and maybe is not worth it for only testing this things. I'm going to t...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

I don't know how I din't have seen this edited: (to ask you, I have seen it and explained it at a previous post) . At this test: eyetracking Why the vertival white lines are completated when you are seen the uper ufo with the same effect as what you say is motion if you see the lower ufo in motion b...

Re: Software BFI Double Image Effect! (Emulation of CRT 30fps @ 60Hz)

Thank you verry much for all the info again, I will read it when I could, but I think that I have read many of it or I know it. I say maybe because I don't have a lab to do all the test and also because one experiment an its conclusion have to be done more than one times by different people to be c...
