Did you switch off surroundling lights?

What color is your wall?

How far is your projector from wall?

Best is to calibrate projector with one of those demo test pattern discs, to ensure the best white level or blacks.

If not helping, looks like a screen is required.

Looking good.

That line in the middle will be a bother, for me.

A question for DLP viewers.

How many actually notice the rainbow effects and get headaches? Is there a % probability?

Was thinking of getting one, but worried, if I'm not affected, but later found out family members affected, then jialat.

So aside from you and gf, no problem with friends and family? They sat down thru a whole 2 hours movie?

Don't ask them about rainbows. Ask them if eye strain or headaches, ,better.

Was wondering where I can see a HD65 demo of a long movie, check if my eyes are ok

It's the headaches and eye strain, that I'm worried about

From wikipedia (http://en.wikipedia.org/wiki/DLP#The_DLP_.22rainbow_effect.22_in_single-chip_systems)

PJ, boss.

Tell me how the audition is done, will see can make it.

Thanks, htkaki.

Been very busy during weekend. It's great to upgrade to 720p projector after using my panasonice ae300 (540p) for so many years.

First difference I see in HD65 :-
1) Contrast ratio increased
2) Details pop out more
3) Image size smaller at same throw distance - no choice 'cos ceiling mount is not moveable
4) Quieter fan noise
5) Faster startup/shutdown time


My only wish was for no.3 to be fixed, but too bad mounting is not flexible enough.

Also too bad HDMI cable has limitations in length. Got the 10m from htkaki but not enough to comfortably go around the room. Right now, it's running hidden under sofa etc... .not neat enough. 15 meter will be just right .... 20 meter will be excellent.

But heard long hdmi cables require adaptor/booster and cost more.

Will try to take pics if got time.

That sounds scary.

Anyone knows the cause of all these random problems?

Anyone knows how to calibrate the picture?

I used my old AVIA dvd, but for the color calibration, it's not suitable. HD65 doesn't have 'COLOR' setting, it has 3 gains and 3 bias settings instead ?! Tried moving them around, but doesn't affect the color patterns.

I calibrated the contrast and brightness but turned out too dark when watching movie.

I hope below are myths especially no.2 - 4.

Cos it's common to turn on projector multiple times in a day. And also during installation, it's common to move projector while switched on.

Color filters are included with my AVIA and I've used them in the past, works fine.


Anyone read about good settings to follow from other forums?

Just bought a voltage regulator for the projector, after reading all those scary news. Cheap RM70 KOSS brand.

Wah. Tv series also watch on big screen.

Nice attempt.

Yep 1000VA, not sure what the voltage means, but I thought bigger is better.

Hahaha. Watts or voltage or amp or ohms, etc., I also don't know what it means.

Hopefully it can tahan few electrical items connected to it.

But got 4 ports. Not supposed to use? How to check?
