Installed LEDs on the cab today. I had all kinds of ideas in my head for holders, brackets, heat sinks etc. Due to time and space constraints I ended up using black duct tape. :o I wanted all of the LEDs at the edge of the screen to get the tightest grouping possible, allowing the guns to work at the shortest distance possible. So here is what I did this round.... > Placed top and bottom LEDs on the edge of the screen centered by measurement. This corresponded with the vertical line in "2. default LED calibration" > Placed left and right LEDs on the ege of the screen based "3. default gun calibration" making sure that they were both the same distance from the bottom of the screen and the line between them was straight. This resulted in them being a bit below the horizontal line in "2. default LED calibration". This is why the top LED ended up high on my previous try. It had to be raised to get the right ratio. This time the side LEDs were moved down to get the correct ratio. This way is more correct because it keeps all the LEDs on the edge of (or same distance from) the screen. Fusselkroete, For "3. default gun calibration", I need to hold the gun right of center or turn it to get the circles in the boxes and lines straight. Both guns are the same way. Is it better to keep the gun perpendicular to the screen and shift it to the right, or is it better to keep the gun centered with the screen and turn it? Either way the mouse pointer ends up shifted left of where the gun is pointing. I was able to get it close with the following offsets: Am I using the offsets correctly or is there something else incorrect before applying the offsets? I could shift the top and bottom LEDs, but that seems way incorrect because then they wouldn't be centered. EDIT: Typed this before/during Randy's post..... |

Test aiming left side with mouse plugin. Increase/Decrese offset by 1 and aim the screen and test if it becomes better. If you think you overshooted make smaller steps. Test till you satisfied. Than do the same with the right side. After your done try again on left and right. Use the same procedure for top/bottm. Your setup Looks like it has zero IR-Offset, from what i can see on the images. I dont see bottom IR. |

It might work, or I might have just wasted my time. :laugh2: BadMouth, if you feel like it, go ahead and check this little program out and see if the result points to where your LEDs are stationed. If not, then we'll know it's useless and I'll delete it. Otherwise, it may help a bit when it comes time to move your LEDs to your cabinet. It's resolution agnostic, but should at least be used at the native aspect ratio of the display. Also, at low resolution some of the screen elements might trample each other. Outside of that, it's been tested and based on the test measurements, it looks like it does what it should. If anyone else wants to run it, feel free. But it's not too exciting :) --- End quote --- Randy, Since the LEDs were already in place I used your program to see if the line would end up where my LEDs are. It ended up above my LEDs by the amount of the top offset. Top offset: 11mm, bottom offset: 11mm, distance between LED centers: 346mm Not sure if it's an error in the program, but I can't move my LEDs very easily at the moment. |

From cm to %. https://geekonarium.de/en/what-is-ir-offset-and-why-do-i-need-it/#example1 But i have better results with try and error procedure. |

LEDs are as close as I could get them to the screen without covering any of it. That's why I was questioning the fairly high offsets. I redid again and ended up with -7 & +9 for left and right and -4 & +5 for top and bottom. It is working good with those settings. I just wanted to make sure that the need for the larger offsets wasn't caused by mistakes in the previous steps. Either way, the gun tracks well after the offsets are applied. :cheers: |
