I've long wanted an Ultrawide monitor - for cinematic gaming and more specifically for getting the best movie watching experience. So what I am looking for is a circa 21:9 monitor that will display UltraHD Blurays at native pixel for pixel resolution. UltraHD Bluray is 3840 x 2160 though of course some of that will be black bars. Current monitors seem to be either 3840x1440p or 5120x2160 so which one of these would display a native image properly. I'm guessing it;s the width that is important i.e. 3840! For some reason I just cannot seem to get my head around this Another aspect is the fact that physical media seems to be on the decline so what is the typical resolution of UltraHD video from streaming services? I don't know because pretty much all my movies come down from PB. edit : made a mistake - seems the common resolutions are 3440 x 1440p and 5120 x 2160p. Which means neither will give you pixel for pixel results for UltraHD movies. Which seems daft, it's like having standard Full HD video of 1080p and then manufacturer's releasing 1800 x 1020 or 2120 x 1100 displays!
