Projectors have come a long way and the ultra short throw ones are pretty intriguing, but they still can't compete with an OLED. You could probably get close if you're willing to go commercial grade (think $50K and up, plus screen). OLED is simply the best TV technology there is right now. Micro-LED will supposedly supplant it in the next couple of years. There are already some Mini-LED's that can come close to the OLED experience. I have both technologies in my home and while I adore the OLED, the Mini-LED often makes me do a double-take because the picture is so incredible.
