These share Epson’s 3-chip 3LCD engine, so the core picture — bright, colorful 1080p that holds up in lit rooms — is essentially the same. The 1100 adds wireless streaming with Apple AirPlay and screen mirroring, so phones and laptops cast straight to the wall with no stick or cable. The 980 skips the wireless tricks and simply costs less for the same panel technology. Households that live on AirPlay: the 1100 earns its premium. Everyone with an HDMI streaming stick already: the 980 is the smarter spend.
