A I own an Ultra HDTV but am still using a regular Blu-ray player. I have no interest in buying Ultra HD Blu-ray Discs but would like to get the benefits of the HDR 10 and Dolby Vision High Dynamic Range (HDR) formats on my TV. Would an Ultra HD Blu-ray player apply HDR 10 and Dolby Vision HDR effects when upscaling regular Blu-rays to 4K, or are those benefits only available with Ultra HD discs? —Jason BF / via e-mail

A I’ve seen references to MQA. What is it? —Phis Tomaskovic / via e-mail

THE VERDICT
Sony’s ultra-short-throw projector can dazzle for daytime viewing and fulfills its promise as a big-screen panel TV alternative, but dark-room home theater enthusiasts may be less impressed.

When it comes to setting up a home theater, the main goal should be to get the largest image that your space and budget will allow. In many cases, that’s going to mean hanging a projector from a ceiling mount at the back of the room and attaching a screen to the wall up front. Next come the light dimmers and blackout shades—both necessities if you want to get the best picture possible from your projection rig.
