Optoma H31 review & screenshots
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.

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.
R-contrast -2
G-contrast +2
B-contrast +2

If you see green in the dark grays/black
R-brightness +2
G-brightness -2
B-brightness +2

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
Picture -
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.

Cinema
Contrast minus 17
Brightness zero
"

"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
Service menu

First ADC
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.

Bravo D2/H31 optoma DVI, I got a read back of 854X480 - 60hz - Mode84 with these settings. Pixel crop zero, Overscan zero.

Hor Freq 47900, Vertical Freq 5994
Vid width 0854, Video height 0480
Hsync 1312 PreHsync 0016
Hsactive 0096 PostHsync 0176
Vstotal 0800 Prevsyn 0001
Vs active 0003 Postvsync 0028
Hspolarity0001 Vsynpolarity 0001
