I dont understand my problem with the green ref. tube. I have a NEC XG135proj. feeded with 1920x1080p through Moome HDMI inut board. I centered the image on the raster but the top of the test image is still curved?? The buttom line is straigt?? All lines are straight exept the top lines? I dont want to use point convergense because i dont think this is the way to go here. Anybody have an idea of want could be wrong? The NEC setup does not allow top and buttom ajustments seperate on the green, only on the red and blue tube. I had to mount the projector a bit out of level "the wrong way" because of the ceiling hight and screen location in the cinema( i had a barco before, the Nec need to hang 5-10 cm higher) Could this be a problem? I use 16:9 screen so I could level the projector and move the image on the raster?? Would this be better???
