*Official* Optoma HD20 Thread - Page 52

Thanks for the tips - I will give those settings a try tonight.

Lapino:

Are you key-stoning at all? I get those lines at the top exactly like you [in your second picture of the PS3] from my PS3 when I keystone. Moving the keystone up or down a notch solves the problem, but every time the PS3 switches from XMB to another source such as a movie or a game, the problem presents itself yet again. When I have keystone set to zero the problem disappears completely. As for the colors, I have no idea. I am still new to this projector business. Its my first one.

I also have this "line" problem, but it was only if my keystone is set to -3. But after adjusting the height of my HD20 and changed my keystone to -2, I didn't get that "line" anymore even after switching between the XMB to another source like blu-ray movies or a PS3 game.

This to me was somewhat strange since its been discussed here many times that the "line" problem would dissappear only if the keystone is set to 0. Either way, I'm just glad I don't have that "line" problem anymore.

My setup:

PS3 ----[6ft HDMI cable]----> Denon Receiver ----[25FT HDMI cable]---->HD20

My HD20 is shipping today. Shweeet!

Of course I had major frustration when my credit card didn't clear and neither the company I ordered from nor my (soul sucking, what is customer service?) credit card company called to clear the purchase since the purchase was larger than normal for my cc (no joke, I try to avoid using them, too many times to no avail).

I am replacing a Yamaha LPX-500 with a new lamp that developed an overheating fault. I was quoted $1,050 to repair it so I had them send it back. I just unwrapped the 30' of bubble wrap and it arrived safe and sound, but do I throw it in the trash now?

Other than offering the lamp for sale, is there any chance of getting something for the projector instead of writing it off?

Thanks,
Bill

First of all, great thread. Been reading from the get go. Guitarman, you seem to have the innards of this unit down pretty good so perhaps you can offer some setup advice for me.

The unit is on it's way so I don't have it yet but I've been doing some pre-arrival setup with regard to ceiling mount, where the top of my screen falls, etc. and I am beginning to get a little concerned about the ability to work with my current arrangement.

I have a 106" screen and the front of the projector will fall at approximately 12' 6" from the front of the screen. It is in my new basement theater and the ceilings are 7' 6". However, there is a soffit above the screen and in the middle of the room in front of the projector placement (see photos).



Therefore, the projector mount will bring the unit to a hanging point just under the soffit. According to Optoma, the vertical shift is 8.31 inches which means the top of my screen will be higher than the center of the lens. Is this going to be a problem? I can drop my screen about 3", that's it! My center channel sits below my screen, low to the floor. I don't understand much about keystone an what effect this will have on my setup.

Also, and this may be a dumb question but I'll lay claim to being a newbie when it comes to projectors (this is my first), but does the lens have to be positioned so that it falls on the center line of the screen or do you center the centerline of the unit on the centerline of the screen? Again, perhaps this is a dumb question but want to make sure before I mount the ceiling bracket.

Last, if the ceiling mount has 15 degrees of tilt, will that help with the screen height and the vertical shift?

Thanks. Any input would be greatly appreciated.

You mean lower, not higher, correct? From the picture it looks like the HD20 will be above the top of the screen (which is what you want) unless you are using an extended mount.


Centerline of the lens. The manual has a diagram with dimensions from the lens centerline to the mounting holes. Use that and you should be ok. I did the same thing as you and prepared the mount beforehand, and it came out close enough. I pointed the PJ slightly downward and used a little v. keystone because I wanted more head clearance

Mechbeav, thanks for the note. Actually, I don't think I described the situation all too well. Essentially what I have is a soffit that runs through the center of my room parallel to the screen wall (you can see it in the photo where the cords are hanging down). The location for the projector mount is initially going to be behind that soffit or at a minimum of 12'6" from the screen. I guess I can move it in front of the soffit but I don't think that throw distance will allow me to fill the 106" but I could be wrong as I don't really understand all this tech stuff...yet! Anyway, if anything the top of the screen, not the frame, at the very best may be at the same level or slightly lower than the center of the lens, maybe 2.5", not 8.31". Is the keystone setting something that will allow me to make the adjustment? see scanned drawing for side view reference of room)

how did you make your reply where it included my original text? can't figure that out. thanks.

Mechbeav, perhaps check out my build thread and see the soffits i'm talking about. Thanks. http://www.avsforum.com/avs-vb/showt...1091009&page=2

I am about to purchase the HD20. I have about 130 - 150 inches of hanging room for a screen. What would be a good size for this projector and how far away should the projector be for a ceiling mount.?

Depends on how high you want the bottom of the screen and also the depth of the room.

This should help you:

If you get a mount that allows the pj to hug the ceiling fairly tight, it looks like you can put the lens just below the soffit, to maximize the distance between the lens and top of the screen. I used the chief RPAUW mount and the lens ceterline is only 5" below the ceiling.

I think the keystone setting will allow you enough room for adjustment, as long as you don't mind or notice the image distortion. I don't know how much offset the keystone can accommodate. Try to avoid using it, because it will also stretch the image a little bit vertically and will no longer be 16:9. Very nice HT BTW, great job!

Thanks for the praise and input. I just ordered the mount from monoprice that was shown/mentioned on page 2 or 3 of this thread. It has an 80mm mount or 3" which will put the lens just under the soffit. Once set up I'll post some photos. Happy New Year and thanks again. I may need more advice on keystone setting though!

Now that I have an Optoma HD20 coming, I want to sell my Optoma HD32 (HD70 clone) and Draper M2500 Cineperm 126" 16x9 screen (has some tire track issues). Do you think I would do better selling individually or together? I've seen the projectors go on ebay for $400+ with close to max hours--mine is around 1200+. but not sure what to do with the screen--originally cost me around $600. Anyone on this board have a similar changeout? I'm going with a big homemade screen for now until I can afford a 159" HP.

I was talking to Star Power today about this projector and the guy said the HD20 was an old projector. Are there comparable or better projectors out for $1000 that are better?

I am looking for mounts for this projector. I need it to hand down about a foot from the ceiling. Are there any at BB or do you have to order a good priced one? How do I know if it fits the HD20?

I am looking for a 120 inch screen for this projector. Anyone know where to get a good deal on a screen for my wall that will work well with the HD20?

JK23--The HD20 is one of the first $1000 1080p projectors out this summer. It's relatively new, and several more are also coming. For the price it's decent rated and I just bought one--after a lot of reading and having a limited budget--that's what really makes the difference for me. There will always be something better and possibly cheaper if you wait until next summer and on and on.

New Optoma HD20 owner here!

Optoma HD20 + Dooable screen on top of the 3 Infinity Primus 362 towers and leaned against the window for now..

Lights on!



Lights off!



With the projector hooked up to my GTX 260 I get
1080p 23hz / 23.976 , 24hz, 50hz, 60hz
1080i 25hz 30hz

with no issues!

The only problem I have is in 1080p 60, the last few lines on the bottom of the screen seem to "lag" and run half as fast as the rest of the screen until I use edge mask...

Is this the best low budget 1080p projector to get for now?

It is rank quite highly at amazon and newegg.

hey I have a similar set up the Bulk head is 9 inches from the ceiling, I just bought the hd 20 and 106 screen Tab tension elunevision from east porters, i need to find a mount that will give me aprox 9-10 inches drop to the lens of the projector, Please help I live in CAnada

If my ceiling mount has a 15 degree tilt option and I don't have the required vertical shift my projector calls for (see above posts), meaning my projector and screen are essentially at the same height, can I tilt the projector up and not have to change keystone settings? Or is this a pipe dream? Thanks.

Mac

It's a pipe dream, unless you want a trapezoidal (non-square) image. The top of the image will be wider than the bottom, so you'll need to use keystone to correct it.

Hello all I am very close to getting the hd-20 some some last questions. My room can be completly dark for movies is the light bleed really as bad as i have read some places? Also I will be sitting 10ft away from 100" screen, projector will be mounted at 12' I have a very loud surround sound set up but during quiet scenes will fan noise be a worry? If anyone has any other suggestions please let me know

I just purchased my HD20. I built my screen (it will be 110'' after border), cables and accessories; just waiting on the projector.





I'll post more pictures when its hung and the projector is installed (hopefully around the 16th). I will do an in-depth analysis on it.

What did you use to build that custom screen?

1x3 poplar... its probably around the 35lb mark total. It has some heavy duty bracing because I plan on swinging it up to the ceiling when i'm not using it. I live in a 15x15 dorm... lots of creativity with my build so far.
