Question: Does the keystone function works using a device connected via HDMI? Can I move the screen up and down?
Document: Set up was fairly easy. Just beware that in HDMI, Component, and Composite Video mode you will not have vertical position adjustments. I understand in Computer Monitor VGA mode you do, but I'm not using that input. This means you need to take some extra care when installing your projector mount and screen so that the lens is perfectly centered. I have it connected to an OTA set top box, a Dishnetwork DVR, a DVD/VHS player and a Blu-ray player.
Recently bought this projector as my first foray into the world of home cinema. I love it and get a great picture, screen size is huge, although currently running a 90 inch screen. This projector gets fantastic reviews on various sites on the net.I currently have my iPad, laptop and phone all connected to the projector. I also use my ps3 to play blu rays, connected via a 1.4 hdmi cable. However, I am unable to view any 3d movies, using dlp glasses.
I was able to setup a side by side comparison with my 50 inch Panasonic Viera plasma 3D TV.I connected ( Via HDMI ) my HP Pavilion 17-e049wm laptop PC and projected to a 60 by 60 inch screen.I opened a web page that had black text on a bright white back ground the window covered about70% of the screen. The TV displayed the bright white screen surrounded by the dark image ofmy desk top. My projector displayed the bright white web page however the dark desk top was washedout.
I can use it in my lounge upstairs in daylight without having to shut all blinds, of course controlled lighting makes the image better.Decently short throw (i.e. big screen size from a short distance, about 140-144" from 12 feet away)Horizontal Keystone is available (vertical keystone is not).3D works well (I have SainSonic 3D glasses) - BUT I seem to get a headache with 3D.
Maybe there is one and I don't know where it is?It doesn't have lens shift (which is available in much more expensive projectors) which is used to shift the image without using digital keystone, i.e. if you want to put the projector closer to one corner and throw the image on the center of the wall you would use that adjustment.
works flawlessly over HDMI and the compatibility with Xbox, laptops, and the desktops I've tried have had no issues.
Maybe I am not one of the people who can see that. People have mentioned that the slower color wheel on this projector can cause rainbow effect for those who are sensitive to it.MOUNT SETUP:I am currently using a shelf and have put the projector upside down on it (difficult to adjust :)) because I did not want to rush and get the wrong product, I just wanted to get the right mount that is easy to setup and works well for adjustments.
So, sometimes switching activities inadvertently switches the projector to the wrong HDMI input. But that's a Harmony Remote issue not the Acer Projector's problem. As for the quality of the picture, of course, with the lights on you'll get some washout but when the room is reasonably darkened like most home theater rooms are, the 1080P Blu-rays are unbelievable. I do see some flicker in bright 3D scenes using 144hz SainSonic DLP-Link glasses and very rarely I get a glimpse of rainbow effect.
Now I get a 120" full HD screen for less than $800! And I can move it anywhere I want!Although some reviews warn about the rainbow effect, I haven't seen any yet.
This projector does have horizontal keystone settings but for people who do not have flexibility in placement: There is no vertical keystone adjustment i.e. the projector bulb has to be aligned with the center of the projected screen otherwise you will get a distorted shaped image, not a rectangle.Apart from these minor annoyances I love the projector. I call them minor because the image quality is still great, it would have been nice to not jump through hoops to set it up.
Answer: Keystone works over hdmi
