Hello, I recently got a really good deal on a tv through craigslist and its a pretty good tv but I am having an issue. I have been hunting to see if anyone had a true step by step guide on creating a convergence overlay template for a tv. On my model ( hcm4215w Samsung) the picture just seems as if the top is stretched and the sides are compressed. I have measured but it seems like no matter what I do the grid I create is wrong. I think it is my math, which is not really my strongest point. Does anyone here have some good advice on how to create a grid? I have velum, rulers, strait edges and even a protractor at my disposal to create this thing. Any advice you give me would be so appreciated you have no idea.
ps. I dont need super specifics if you don't have them, just some way that I can hope to accomplish this.
