En revanche, la qualité sonore des ho n’est pas au top mais, comme nous utilisons la sortie audio vers un ampli hi-fi : aucun problème.Le ventilateur est présent mais sans être gênant ni plus bruyant que notre ancien appareil. Je recommande. ### ⭐⭐⭐⭐⭐ Excellent *by on Reviewed in Canada 2 August 2024* Great picture and very bright for daytime viewing. Love it ### ⭐⭐⭐⭐⭐ Was will man mehr für wenig Geld *by on Reviewed in Germany 5 January 2022* Klein, leicht, intuitiv bedienbar. Günstig, gestochen scharfes Bild. Ton läuft über 7.1 Anlage. Optischer Anschluss fehlt, daher nur Analogkabel. Aber trotzdem klasse Sound. Bisher nichts Negatives zu berichten. Die Bildqualität ist brillant, selbst HD Filme sind scharf. Das Bild ist hell genug, wobei wir hauptsächlich bei abgedunkeltem Raum schauen. Fernbedienung ist auch okay.Leider seit kurzem auf HDMI 1 Eingang Probleme und Abbrüche. Nach Wechsel auf HDMI 2 Fehler nicht mehr aufgetaucht.Gerät wird reklamiert, bestelle das gleiche wieder. ## Frequently Bought Together - ViewSonic PX748-4K UHD 4K Projector with 4000 Lumens, 240 Hz, 4.2ms, HDR Support, Auto Keystone, Dual HDMI, and USB C for Home Theater, Stream Netflix with Dongle - VIVO Universal Adjustable Ceiling Projector Mount for Regular and Mini Projectors with Extending Arms, White, MOUNT-VP01W - VIVO Universal Extending Ceiling Projector Mount, Height Adjustable Projection, White, MOUNT-VP02W --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/339185114-px748-4k](https://www.desertcart.co/products/339185114-px748-4k) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-16*
