ViewSonic LS740HD Full HD 1080p Business Laser Projector (High Brightness 5,000 ANSI Lumens, 300-inch Large Screen, 1.3x Optical Zoom, Keystone Correction, 4 Corner Adjustment, 15 W Speaker, Equipped with 3D, Low Power Consumption, 360° Projection, HDMI, USB, Educational)

4000lmパナソニックとの比較では、明るさが格段に上がりました。ピント調整がレンズ外側カバーを手動で回すのがわかりにくいですが、慣れれば問題ありません。画像もパワポ中心なので問題なし。

とても良い

家庭用で使用してます今まで使ったプロジェクターで最も明るく静かです

Super,Vp silencieux et très performant et unr grande luminosité. L'image et top, je n'ai pas encore recentrer le pire de fixation qui et légèrement a décoller par rapport a mon ancien VP, grâce a la correction du trapèze pour réaligner l'image, c'est top.Je n'ai pas rallumé ma tv depuis, car aucun pb en journée (évidement pas de plein soleil sur l'ecran).

Se ve muy bien incluso con mucha luz natural. En dos semanas con el, va todo perfecto

I picked up the projector for an outdoor movie and boy it did not disappoint! The sheer brightness of it lit up our whole 25 foot screen! The image looks great for 1080P and I have no complaints about the color quality! No reliability issues and the laser is still going strong. The noise level is very low. The only thing that may be concerns is the speaker quality. They are very muffled and sound blown out. This isn't a problem for us as we use external speakers for our audio.

Purchased to replace an existing projector which had failed. Easy to swap over and set up, super bright and great picture quality.

I've had a few projectors over the years and the thing that always frustrated me was needing total darkness for a watchable picture. This one is different. At 5000 lumens I can leave a lamp on or have some daylight coming in and the image still holds. That changed how much we actually use it.The laser light source is the other big thing. No lamp to replace later, and it's at full brightness the second you turn it on instead of warming up. Shuts down fast too, no cooldown fan running forever.Picture is sharp corner to corner. Text is clean enough that I've used it for work presentations without anyone squinting. Colors look natural, not oversaturated like some projectors push them.Setup took some patience getting the placement right, but once it's positioned the keystone and zoom handle the rest. Mine sits on a shelf at the back of the room.Fan noise is there but it drops below the audio once something is playing. Not silent during a quiet scene, just not distracting.This is a serious piece of equipment rather than a casual portable one. If you want a projector you'll actually use regularly instead of only on movie nights, the brightness is worth it.
