HD70 Tweakers Thread. - Page 3

I'm not sure I'm the only one having problems. The problems I have are from a calibration point of view. guitarman you've talked about all the different modes being great for this or that. Thats fine if your willing to sacrifice color accuracy for a bright plasma like image for hdtv sports. I might even use one of those mode for animation or somthing like that. For me though I watch only movies in my theater and for that its gotta be d65 or I notice strange things going on with the colors. I dont know how many other people who have the hd70 have even seen a properly calibrated set. They may not know the difference. Even if they did they may not care. I do care and for me this thing has serious problems that I have been unable to fix. I'm sure eveyone else has the same problems. Its just that they dont know or dont care about them. If your unit works so well post some gamma charts and rgb tracking charts. Maybe it is just my unit. In that case I'll send it back to optoma and get a new one.

I have a hard time making the projector look bad. Could be you have an off one. Most of what I've read is people are happy with it and they're not new to projectors. So you're dumping your HD70?

"I dont know how many other people who have the hd70 have even seen a properly calibrated set. "

I've tuned 300 projectors for people in the last year or so. My HD70 looks great with just a brightness and contrast adjustment. We're watching Seinfeld right now, it's TV and colors look normal and natural. Bones just came on same thing, looking gooood!
I think you need another machine.

Its possible I do have a bad one. I'd still like to see what your gamma and color tracking results are. I dont want to have to judge your hd70 off your screen shots. Just by your screen shots though I can tell yours looks like garbage too. Your greyscale is way off, suffers from blown out whites and lack of detail on the darker end. Some of that is subjective. Actual measurements are not. I just want to know what your getting from your 70. YOu did a great job when you reviewed the h31. I bought one because of what you said about it. I then bought the hd70 because of what you said about it. I consider you an asset to us at AVS. However your motives for praising the hd70 have already been called into question by others here. Alot of what your saying here IS starting to sound like a sales pitch. You have the equipment and the know how to show us what this thing is actualy doing. Not just hey guys this thing looks soooooo good!. Any idiot can say that. Show us what the 70 realy does because mine does not do what you say yours does out of the box at all. Mine after over 10 hours calibrating do not do what you say yours does out of the box.

"I ran a graysale check with Cinema/Film and it cam in flat bouncing around 65/66k. As far as screenshots it's better live but maybe you're not use to what D65k looks like exactly. D65k adds warmish look to images."

"Contrast measured 2700.1"



"Brightness 20.50ftc, that's 818lumens on a 106"diag 1.0 gain screen."

I could not make all of those statments true of my hd70 all at the same time if I had a magic elf living in my audio cabinet. And I used to. But he moved out because my denon gave off too much heat.

From reading I don't think you'll ever like the projector, better let go. I hope it's early enough to get your money back from the dealer?

If anybody trys these first jot down all your original numbers especially the RGB numbers.

Can any of the current owners let me know how big an image can hd70 throw without losing much pq and sharpness. I have a room that is 18' x 22' with 11' ceiling and I wanted to see how big of an image I can get from HD70.

Thanks!

Couple of observations here. I really want to use brilliant color because of the added punch, but find that it does add some noise in certain scenes - not all, but it's definitely there, I'm surprised that no one has made reference to this yet. Also I can crank sharpness all the way up and don't really see any problems, which is kind of strange.

As far as I can tell, the SHARPNESS slider is like the extra dials you had on old TV's and Radios from the 50's. You could turn them forever, they didn't actually do anything

Brilliant Color REALLY looks amazing with the xbox 360 via component. I cant tell you how stunning the picture looks. Its insane. I'll post up the settings i used for the 360 tonight.

What happening with your projector?

My PJ? Haven't had a chance to touch it since Monday. ND filter should be here tomorrow but haven't had a chance to try tweaking it out again, bring down that black level a bit.

The SHARPNESS slider on my rig wont do much for me, because the only source I have connected to the PJ right now is the Tosh HD player, so everything is upped to 1080i before being dropped to 720p at the PJ.

But the Sharpness slider really doesnt' appear to change anything in Avias Resolution test.


I'm hoping to have more time to mess with the PJ tomorrow, but if not it'll have to wait until Sunday.

Looks INSANE.

Hey guys...been tinkering with my new HD70 for the past few days. Last night was the first night of extensive testing and capturing shots with my Nikon D50 to compare to my 4805. Tonight I decided to take my 4805 down from the ceiling mount and put the HD70 up for replacement.

I'll spare the review for the moment as I am building my opinions through early use. The HD70 looks great except for one thing that I am unsure about. Using the DVE disc, I was checking the first sharpness calibration pattern, and noticed that the HD70 appeared to have ghosting lines.

It's hard to describe, but it's different than a "hard edge" as sharpness should adjust. I am just seeing that a short distance off lines on both sides there appears to be a ghost line or some sort of odd pixelation going on...well, that's still a poor explanation. I wish I could take a good screenshot of the effect, but it really affects straight lines and things like text with the issue seemingly a distortion in the sharpness of the edge of text or straight lines when you view from a normal distance. This is over both HDMI AND Component with my Oppo DVD player. I was also noticing this weird effect on text watching Dish Network HDTV (a football game).

This may be a signal degradation issue, but I don't understand why this would occur over HDMI?

I will continue to tinker to see if something is the root of this issue, I don't remember seeing it last night when I had the PJ sitting on a table. I need to fire the 4805 back up to make sure I am not seeing things that aren't there. Any thoughts?

Oh yeah, color calibration seems to be kind of difficult as I couldn't cause much of any effect on the color squares calibration provided on the DVE DVD. The Blue test seems to be pretty spot on by default, and red is pretty close, but green is way off, and no matter what I changed in the RGB advanced settings, I couldn't cause much in the way of any effect on the colors.

I'm wondering if some quality control issues exist in this first round of HD70s out of the gate. Last night things were looking great, especially in hooking up to my 360, but tonight the ghosting lines (almost like double vision) and the lack of color tuning ability has got me scratching my head a little.

I also agree with HeadRusch on the sharpness slider...it seems to cause very little change on either extreme. It is noticeable, but very slight.

Hmm, i just tried going from one end to the other with sharpness, and the difference is very apparent for me. Tried with the 360 and the PC, same thing, huge difference from one end to the other.

I'd like the answer to this too. Anyone?

These settings were a big improvement for me, thanks. I think though I still have an issue with yellow though, there is some green creeping in here. Anybody else seeing mustardy yellows?

After some more use tonight, I think I may have just had a weird issue with the signal last night, as I have not noticed that "ghosting line" or "white line shadow" that I saw last night, or at least it wasn't as pronounced. The thing is pretty close to calibrated out of the box, but I did decide to bump the blue bias back a little, and bumped the red up a notch to give the picture a bit more color vibrancy. Sure, this may not be accurate, but I'm kind of stuck on the apparent better vibrancy of my 4805's colors.

After several hours of watching stuff on the unit, I no longer cared, the HD70 is impressive. Different than the 4805, no doubt, but it has enough big time benefits to warrant its trumping of my venerable Infocus! I have lots of screencap comparison shots, and will post them as soon as the AVSForum rules allow me to shed complete newb status.

DO I need 5 posts before I can post a URL?

This is filler!

Mmmmm, filler...

Double OOPS...I posted a bunch of links here, but they don't really pertain to the "tweakers thread". I meant to post them all in the "The new budget king" thread. SO I am going to delete my original post here and re-post the comparison shots in that thread.

blitz or Guitarman... would one of u be so kind to run a calibration via VGA input?

I would run it myself but I am unable to get access to the Color & Tint functions through VGA and all I would be able to tune is Contrast & Brightness with AVIA or GETGRAY.

For anyone feeding their 360 to the HD70 via VGA and who may be considering the purchase of one of those Microsoft HD-DVD add-on drives, the calibration of the VGA output is a big money ticket.

Ummm, websnappy wants a username and password... ERROR 401: UNAUTHORIZED.

I have 0 intrest in HD-DVD (i dont think its going to be the winning format, lets stay out of that in this forum however) and since i have a HTPC hooked up via HDMI, i dont really need the VGA for the 360 to upconvert DVDs. I do have the cord but just no intrest to hook it up and get it calibrated.

I'll take a look at vga for you. The fact that it doesnt have color or tint makes me wonder if maybe something in its color processing isnt bypassed. I may actualy be able to get a decent greyscale out of that port.

Ooops...sorry folks. I just removed the folder restriction on my website. I tried to set it up originally so that I could just give people root access FTP style. Give the change 30 minutes and it should permeate through my site. If not, you can use usernameublic and passjcompare to see the images.

Have you calibrated your HD70?

Just from looking at the pics, you can tell the 4805 is oversaturated by a huge margin. But your HD70 shots show a green push, albiet much more lifelike colors.

Red, thanks alot... I will look forward to that.

WyattERP, I think there may be a Lepricahn living in your PJ. Wayyy tooo much green. Thanks for the screenies though.
