I started DisplayMath after visiting BFI IMAX in London. I wanted to compare the cinema screen from my seat with my 77 inch TV from the sofa at home Diagonal inches were not enough. The screen shape and how far away I sat changed the answer This is the comparison that got me started. The cinema seating geometry is an estimate https://displaymath.com/?d=bfi-imax-row-f,samsung-s95d-77_300cm#canvas The app now draws TVs and monitors to scale and compares their dimensions, pixel density and field of view. The screen comparisons are free and need no account On a supported iPhone you can preview a specific TV at real size in your room using AR. There are also tools to measure distances and heights with your phone I used AI coding assistance while building it I would like feedback on the first visit. Does the comparison make sense straight away, or do you have to experiment before you understand it?   submitted by   /u/xcafebabe [link]   [comments]
