I am using Barco ELM R18s. I have a fairly constant flicker on a few lines at 1280x1024 75Hz. However, while it is noticable on the line-up grid, it is not noticable on the content I have at the momemnt. The content may change to be more graphic with more fine lines and that may show the flicker.
I do not have a lot of head room on the processing side, since I have to run sxga using photo jpeg at 60 sq. Thus I want to avoid running at 60Hz.
I have re-configured the grapics card to overide os settings, but seen no noticable change to the 60hz output.
