Hello everyone, I've only very recently discovered this project and I'm very excited; it looks like you have a great community here and I can't wait to get involved Now, I apologise in advance for what are probably _very_ stupid questions, I have searched around for the answers but I feel I must be missing something. Why do most people seem to go first with the hdmi splitter > converter > grabber input method? Given the issues with resolution matching I don't understand the advantage of choosing the HDMI as the grabber input. What is the max resolution Hyperion can actually handle? If a 4K @60Hz signal gets passed through a HDMI grabber that outputs PAL/NTSC format will it not be output at 720x576 @25Hz or 720x486 @30hz respectively? Unless you equip your TV with similar number of LED as pixels then what's the point? The limiting factor will always be the number of LED won't it? Honestly, I'm not trolling. Please forgive my ignorance, I'm very new to this sort of thing I'm trying to get together the parts I need to get this running with my setup (4K) but it seems to me that unless I was going to fit 3840x2180 LEDs on my TV (imagine the power consumption!) then I don't need anything even close to an HD signal to feed the image grabber. I have a Sony STR-DN1050 AVR, which can output at 4K, connecting my PS4 Pro and Xbox my 4K TV over a single HDMI (ARC). Obviously, I don't want to cripple the 4K signal by placing a lower resolution device in the HDMI chain. But, my amp also has a composite video out so I'm hoping I can just connect a grabber directly to that. Has anyone else done this?
