I currently have an 'old' Epson 5040UB, 1080p projector (no 4k enhanced) but want to project a bigger screen size (150"+). However, any bigger with this projector produces noticeable Screen Door Effect (SDE). So I'm considering upgrading. Which type of projector should I buy that will allow me to go bigger? Options are to upgrade to the newer pixel-shifting '4k' model, or similar, or wait 6-12 months for the genuine 4k to come down more in price. Note, I anticipate using 1080p source, and often DVD, for the next 1-3 years as HDR/4k content is hard/expensive to get here in Australia. So I expect to upgrade my PC and use MadVR for up-scaling the 1080p Blu-ray source. So obviously, HDR is not a major consideration in the upgrade. So opinions please, 4k enhanced or 4k genuine, or either - or should I forget the whole idea because 1080p and lower res. will just look very poor on a 4k projector? Cheers!
