Optoma has a new 30 version the H31 w/480p Dark chip 2, native widescreen. Same case and remote as the H30 with added DVI, Component, in place of the VGA connection. First off Mike is right the Dark chip2 does produce a very dark black. Lucky for the H31 it does because this thing is a light cannon and in econo. So you get a large swing from blacks to whites. Contrast is high/brightness is high. Colors are intense with the classic Optoma citrus juicy look.
Optoma added some excellent aspect features to the H31. It has a 1080i 1 & 2, these come in handy because when viewing OTA 480p you can expand the image, making for thin bars on the sides and keeping the image natural. We all like a bigger picture.
Theres an feature called Edge Mask, this is good if a TV signal shows garbage around the rim. Hit the Edge Mask on and it disappears. Nice feature
There's several aspects for 4.3, Normal, 1.66, 1.85, 2.35. Normal is standard size, the other expand the image. These are also useful for non-anamorphic dvds although there's a discrete button on the remote for Letterbox which will handle NA-dvds also.
Then there's this great feature for electric screen users or maybe manual pull types. It's called image shift. Like last night I viewed Bourne Supremacy which is 2.35. You use the image shift to raise the image up to delete the top black bar and in turn raise up the electric screen to delete the bottom black bar. You end up with a panoramic 2.35 setup. Very nice
Also this procedure can go in reverse. A user with a Theater view Dalite type screen that pulls up from the floor can set the image shift down and in turn lower the top of his screen down. Deleting the 2.35 black bars. Each function has a memory setup to simplify with a hit of a button.
On to the screenshots.
I used a Phillips Q50 in progressive for these shots.
Also took a look at DVI with the Bravo and it's very clean. Seems 480p looked the sharpest. Avia showed Zero overscan.http://www.cigarbest.com/sales/h31fifth1.jpghttp://www.cigarbest.com/sales/h31fifth2.jpghttp://www.cigarbest.com/sales/h31lotr1.jpghttp://www.cigarbest.com/sales/h31lotr2.jpghttp://www.cigarbest.com/sales/h31lotr3.jpghttp://www.cigarbest.com/sales/h31glad1.jpghttp://www.cigarbest.com/sales/h31glad2.jpghttp://www.cigarbest.com/sales/h31glad3.jpghttp://www.cigarbest.com/sales/h31glad4.jpg
How to eyeball a better grayscale.
"Some tuning tips for all displays that have advance RGB-adjustments for grayscale.
After making initial Avia changes take a look at the Avia Needle Pulse pattern to see that there's no color tints in the Gray to White steps in the upper part of the pattern. The Pluge pattern also in Avia called Black Bars+ Log Steps. It's found under Video Test Patterns/Gray Scale & Levels/Black & White levels -
If it's not dead on grays to white make final changes with the user advanced adjustments.
Example - you see red/pink tint in the light gray/white.
If you see green in the dark grays/black
You see how it works, color in the light grays you use the RGB-contrasts
Color in the dark grays you use the RGB-brightness to fix.
enjoy and get good at it, can really make a huge difference "
Also I would start by first deleting the color you need until it's out of the grays. Lets say it took 8 clicks minus on the red to get there. Instead of leaving this make it just 4 clicks and inturn add four clicks more to the Blue & Green for better balance."
For you guys using DVI here's the numbers for D65k
First in the service area setting up Image/Film gamma 1
Gain Red 167
Gain Gr 158
Gain Bl 155
Bias Red 123
Bias Gr 125
Bias Bl 125
DLP's are all at 32
Next PC gamma 1
Service picture area remains the same, just use the User Advanced RGB
Red Contrast minus 2
Gr Contrast 0
Bl Contrast 0
Red Brightness 1
Gr Brightness 0
BL Brightness 1
Don't change any other things in the service menu, just Picture. Don't mess around in there. Oh plus write down your original service Picture RGB numbers.
After changing use avia for black and whites my user blacks&whites were the following, at least for PC gamma1 which I'll be using.
Contrast minus 17
"Here's some colorfacts numbers for analog 480i/480p
480i Film gamma 2, yes that's right Film needs to be used for analog, PC wouldn't work it would crush out the whites, PC works for DVI though.
Service Picture RGB's
Gain red 165
Gain Gr 159
Gain Bl 155
Bias Red 128
Bias Gr 125
Bias Bl 129
480p component/analog, Film, gamma 2
Red Gain 170
Gr Gain 167
Bl Gain 169
Red offset 72
Gr offset 59
Bl offset 62
Picture service area,
Gain Red 122
Gain Gr 124
Gain Bl 125
Bias Red 124
Bias Gr 126
Bias Bl 124
If you try any of these pls write down your original numbers.
480i/480p numbers done with Denon 1600/RP82/Xp50, same deal. Any decent analog player that has normal blacks may work for these numbers, and maybe not. So save your old numbers incase you want to go back.
