Choosing between projectors & screens means deciding whether the priority is a self-contained screen setup or a more specialized home-theater arrangement. Alvar RV400A and Hisense PX3-PRO serve different briefs, so the fastest route to a smart choice is to match the intended viewing style before comparing technical labels.
Quick verdict
Alvar RV400A is the straightforward route for a screen-included movie setup, while Hisense PX3-PRO is aimed at a 4K UHD home-theater brief. Pick Alvar when the package format and portability are central; pick Hisense when the 4K UHD specification is the reason you are shopping. The two projectors also share Bluetooth, HDMI Standard, and USB connectivity, so the broader decision is about the viewing setup rather than those ports.

Where each product wins
Alvar RV400A
Alvar wins when portability and onboard audio matter. Its feature set includes built-in speakers and a universal remote, while backyard parties and travel are named as intended uses. Those details make the RV400A a natural match for movie nights that move between spaces, without asking the shopper to prioritize the specialized format represented by the Hisense.
Hisense PX3-PRO
Hisense wins when the use case calls for an ultra-short-throw arrangement with a large stated screen range. The description identifies TriChroma triple-laser projection, viewing from just inches away, and an 80-150-inch range. Its title also names Xbox design, giving console-focused shoppers a concrete reason to favor the PX3-PRO. These details make the Hisense the more targeted match for a large-format home-theater plan.
Product notes
Alvar RV400A 1080P Bluetooth Projector
Alvar RV400A makes sense for shoppers who want Bluetooth 5.1 and a New condition. The projector is identified as 1080P HD and includes a built-in screen and speakers. Its concrete limitation is the resolution detail: maximum resolution is listed as 1080p (FHD), but native resolution is 1280 x 720. That distinction matters if native pixel count is central to the purchase. It is also marked portable, with backyard and travel use called out. Bluetooth 5.1 and the screen-and-speaker combination give it a clear role, but the native figure remains the key point to weigh.
Hisense PX3-PRO 4K UHD Triple Laser UST Projector
Hisense PX3-PRO is the fit for shoppers who want DLP display technology and a 16:9 aspect ratio alongside the product's 4K UHD positioning. Native resolution is 3840 x 2160, a concrete specification for comparing display formats without guessing how the number should perform. The main limitation is condition: it is Certified - Refurbished. The title also references Xbox design, which gives console-focused shoppers a clear reason to choose it. The Hisense purchase answers a specialized home-theater brief rather than the Alvar's portable format.
Final choice by use case
For flexible movie nights, choose Alvar RV400A if its New condition and 1080P HD title fit your expectations. For a defined home-theater brief, choose Hisense PX3-PRO if DLP display technology and a 16:9 aspect ratio are the deciding specifications. The listed prices are $21.89 and $2,400.00, a $2,378.11 difference. That gap makes the use case decisive: Alvar RV400A is the portable choice, while Hisense PX3-PRO is the ultra-short-throw choice.
