On my screen, I like Brilliant/On and Full (as opposed to Eco on whatever that setting is). "Torch" mode??? Hardly....

I'm a crappy critic I suppose. It all looks good, but on a 120" screen in 3D mode, the brightness adds a little bit. Maybe I didn't notice the "better blacks" because I was watching "Underworld Awakening" and thought the costumes to be just fine.

Yeah maybe I shouldn't have called it torch mode, but is what I see wrote a lot on projector being in full bright mode vs eco mode and is what came out while typing. Maybe should have been more clear on noticeable difference too. It isn't a huge difference but can be seen when switching back and forth. My 100" screen to my eye looks better in eco mode for 3D then full mode or torch as I called it earlier, only two choices.

They have infinite resistance when tested with an ohm meter due to the fact there is no physical connection between the electrodes. Once the ballast charges up the "primary" electrode it arcs through the compressed gas in the bulb to the second electrode. That glowing arc is what's making the light.

Their susceptibility to failure is more due to the high voltages needed to create the arc in the first place. That's why leaving a lamp on is better for it than power cycling it if it is going to be used with only a small break in between viewings.

Your correct with this and the projector asked about. But not all projectors use a UHP lamp so some can be checked with a typical ohm meter. I was wrong though so thanks for correcting me on that. Should have researched more before replying so quickly. I was unable to find a easy method to inspect a UHP lamp without having to purchase one and try it out, do you know of one?

Non easy method is set up a ballast and see if it works.

Yes will show open loop with a typical low voltage ohm meter and doubt most have a megger ( high voltage ohm meter) but I am thinking it would show the resistance. Since if it was truly infinite resistance it wouldn't pass from one electrode to the other.
Most typical ohm meters are 9 volts give or take. Fluke, Megger and other's make high voltage ohm meters for testing insulation usualy. Thinking a 1kv ohm meter would be able to test these lamps but I am not sure, do you know Walternate?
Oh and high voltage ohm meters are not cheap, just thinking possible methods to test these lamps.

Right. I (basically) get how they work and probably wasn't that clear. When I said "high resistance connections", I meant that if a connection to the bulb (or perhaps somewhere else in the support circuitry) itself had higher than normal resistance, the resulting voltage drop across that junction could cause failure. You clearly know more details than I do....hence the question from me. Clearly that's just one way to lower a voltage, but I don't know how they generate the high voltages in the support circuitry.

InCali when are you expecting your meter? I really wanted to test the 3D output today while watching the golf tournament on NBC, they have a great signal and I wanted to try 2D to 3D but alas my yard work went way too long. After Nascar I may play with this but I doubt racing is good 3D conversion stuff. I may just try something else and go service menu to check this out. BTW, I have heard nothing back from Acer regarding my last support request on the blur issue. I may go chat support here soon as I suspect Ryan can no longer respond to my questions since I elevated my request for support beyond his level.

i use the color corrector on and off. some movies really help to have THX certified color, makes the picture look great, some movies its not necessary. t he video above explains the effect perfectly.

OK. I bought the color corrector (the one you got and not the one on youtube ) and a little shorty HDMI cable. I figure for less than $100, it was worth checking out. It also means I can just use one of the longer 40' cables (I'll have a backup HDMI cable or have one for a different use).

Do you have to select a HDMI input using the remote or will it auto-select if it senses a single active input? It would be nice if I could forgo having to go into a menu to select my input.

I assume the six (6) user-controlled color settings are separate settings and not 6 adjustments of a single setting?? If so, that addresses what I see as a major weakness of the Acer.

I have no frelling clue what 10 bit color means unless it means you get 10 bits of each color per pixel. I have no idea whether this is better or worse than what I'm seeing now (if my assumption is even right) or whether this is just some manufacturer load of BS that's thrown out there.

Anyway, I'm looking forward to seeing how this thing works. It appears that, at the very least, it will give me some added functionality.

what i like about the box is that it remembers the color settings, i have the color set as default on the projector and use either OFF, 2 or 5 button setting.

i believe 2 is for cinema color and 5 is for brighter room. i toggle based on the movie. if you have an harmony you can setup an custom IR to the CC box. if you see my pics from earlier in the thread it does create the wow effect for animated movies (like the pixar Brave trailer)

I see....so the 6 settings are presets and can not be customized. That's okay. What about the inputs? Will it auto select if there is only one live device? I have a universal remote (URC W7 or something like that) which has a learning function that appears to work pretty well. In fact, I use it for my logitech surround system, Acer PJ, cable box, and Sony 3D blu ray player and have never had it refuse a command. It doesn't have some of the advanced functions (that I never use) but it only costs 20 some bucks. It also has a back light function which I find helpful.

If you don't have a U remote, this one gives you good bang for your buck.

yup, no customization you will either like the presets or not. the great thing is it remember its regardless of the input or mode, so i don't have to touch the acer menu or settings even in 3D mode. i know the acer had a hard time remembering color presets.

yes, it auto selects the live hdmi input.

Are those the green frog pictures from March? I'm assuming the greener one is using the processor and the more washed out one isn't?? If this isn't it and there are others, let me know.

Thanks for the help. Much appreciated.

those picture didn't quite do justice. maybe a comparison shot with SLR on tripod would have been better. you'll be able to try it out soon and give us your impressions. any news on the firmware? i researched acer projector firmwares and found some stuff on older projector firmwares but nowhere did i find a way for users to flash the firmware...

I've heard the firmware update will be available late this month to the middle of next month. We should probably wait until then before asking. It'll help in the future if I'm not writing everyday. I'm trying to find out exactly what the firmware addresses and will get back to everyone if I can find out.

Everything I've heard says that the PJ "HAS" to be sent in for the firmware update.

The light meter just shipped:
Your estimated delivery date is:
Tuesday, May 22, 2012

I'll check out the color processor and let people know. I'm thinking I might get some calibration equipment and try my hand at that. Any suggestions out there? I don't use HTPC.

Maybe get a smaller screen???

Since the processor ships from SoCal, it's already out for delivery. I'll probably be hooking it up later tonight and will give people my impression of how things go. Once I figure out the whole calibration process and get whatever equipment I need, maybe I can be more precise.

Ha! Been trying. We sit 9' away and the 92" screen is just a bit overwhelming. For some reason it wasn't with the panny ae3000u LCD PJ. Maybe it's the DLP? I am rainbow sensitive. And it seems to wire me up more as going to sleep after watching it takes much longer.

Anyways, I dezoomed it to about 55" last night and it was much more tolerable.

from Art's review

Color accuracy could be better. "Out of the box" is very watchable, but you have limited ability to improve it further with a calibration due to the lack of othe color controls used for grayscale balancing. Realizing that most people buying a sub-$2000 projector are not going to calibrate, that probably doesn't concern them, as color is already pretty good, just a bit thin on red.


i think the CC box address this weakness in the acer.

I got my son an 80" Elite 1.1 gain screen for his bedroom and gave him my old Sanyo which he plays WoW on and watches TV. He's pretty stoked. In case it helps, the screen cost less than $100 delivered. I think that's about the smallest 16:9 screen I could find. I saw some smaller ones, but they were either 4:3 or square.

From an Audioholics review; which I found pretty funny.

For pro installers, the H9500BD can also be controlled via RS232 and there is a USB connection for theoretical firmware upgrades.

I am sure Acer will be using the USB port to upgrade the firmware. For whatever the reason they aren't allowing projector firmware out in the wild. I can only guess that the designs are similar enough that you could hack it to ru on another projector. Or maybe it is error prone and better left to the technician.
