not necessarily true, fyi

pixel shift既4k都係display緊8mil pixels on screen, 但係1080p只有2mil pixels. 不過epson既4k enhancement只係出到4mil pixels
when it comes to projector, 除左resolution之外, brightness, contrast, lens quality都係影響image quality既factor
最直觀就係去showroom睇下, 都幾明顯睇得出1080同4k既分別, especially係香港普遍咁細既空間入面玩theater
1080hdr都係好機, 特別係用黎打機

不過始終都係budget projector, 如果佢出埋4k就唔係依個價, uhd35都做緊1299usd
