The hardware properties of the PH730 manufactured by Acer include 1200 ANSI lumens, a WXGA 1280 x 768 resolution and a contrast value of 2500:1. According to Acer, the included lamp lasts up to 2000 hours. Regarding projection size, the value of 1200 ANSI lumens allows for an image width of up to 352 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 235 cm. A look at the data sheet confirms a very subtle fan noise for the projector at just 28 decibels. Since entering the market in 2006, production has been discontinued; the manufacturer no longer actively offers the model.

Quiet, inexpensive and good projector for home cinema
Because of the extremely unfavorable offset, which has already been criticized, it can‘t satisfy all round. Its yellow display is also not entirely convincing due to a slightly greenish nuance (don‘t get me wrong, almost all projectors have their problems here). The color interpretation in desktop mode is also not the best (blue appears greenish). But if you want to use it primarily for photos and films, this won‘t bother you. Because in pure image reproduction mode, it impresses with brilliant images. Photos appear vivid and color-balanced in a way that a slide projector could not do better (I tested this with a test CD from Heimkino). If it is (and remains) positioned in such a way that the projection is at right angles and in the optimum aspect ratio on the (screen) wall without keystone correction, you have an exceptionally good projector for the money. In DVI mode, the image is so sharp that you can even distinguish the individual pixels of the image at close range. It doesn‘t tolerate residual light very well, but in a dark projection room it definitely gives you that cinema feeling. You can only get more black and grayscale resolution for twice or three times as much money.

v-sync.?
how can the projector display 50Hz if it only starts at 56? error in the data sheet?

how can the projector be identical to the optoma HD72i, when (according to the photo) it has completely different optics and the lens on the other side...?! i think the PH730 is very good (price-performance ratio is great), only the adjustment due to missing lens-shift is very cumbersome for mobile use (unfortunately the upward pointing optics does the rest).

Same as Optoma HD72i
According to forum information, same as Optoma HD72i (please ignore rating, why can‘t you leave a comment without choosing a rating?)
