M9702 Media Player

anfieldude — Tue, 27 Aug 2019 13:43:42 +0800

Not sure if there has been any info before, but I hv been testing this media player - M9702 player. Its an interesting player to say the least.. There are 2 HDMI outputs (1 X 2.0, 1X1.4 audio only), gigabit LAN port, and 1 usb to TTL port for future upgrades and 1 optical out. The player runs off Oppo jalbreak firmware (latest version), supports HDR10, HDR10+ and Dolby Vision. It seems to play everything that the JB Oppo plays (ie, UHD iso, BD iso, BD folders, mkv etc) and supports Dolby Atmos & DTS X bitstreamed. I will add pictures later if possible but its the only Dolby Vision playback device (for iso and folder structure) that I see in the market now. I'm not sure how long it will last as it uses the same Mediatek 8581 chip that the Oppo and Pioneer UHD players use. It also plays SACD iso.

Added info: Does not come with a BD-ROM so only plays iso, files etc. Comes with a backlit remote. Oppo remote works as well if u have one lying around.

There are 3 parts, u can check them all out.

The latest units do not have the coaxial out.

Projector Setup in a Living Room - Thought Process

anfieldude — Thu, 14 Nov 2013 13:18:43 +0800

Projector Setup in a Living Room Condition - Discussion/Approach/Setup/Results/Conclusion

Background:

As some will know I am a certified calibrator (ISF & THX) and have calibrated all kinds of displays in all kinds of environment in Malaysia and Singapore. From dedicated home theater rooms to humble computer display setup I hv come across various setups all round.

This thread is not about debate between LCD/Plasma/Projection as each has their purpose and place but more of a journal/collection of thoughts/ideas if setting up a projector in a living room environment can be done, and if yes, can it be done successfully.

I currently own a Kuro 60in in the main living area as a frame of reference. I hope to document how I am/will go about the setup considerations, screen selection (size and type) and projector selection.

I will try my best to add images on how I achieved this (images of the home might be less as I am not a fan of having images of my home floating about in the internet) with reservations.

I will also post my impressions on the final results (if possible with some other screen comparisons).

Once a baseline is achieved, I was also planning on "trying" some DIY paint based solutions that are available in the AVS forums/HomeTheaterShack forums with my take.

This whole exercise will take time and as life goes on regardless of the home theater scene, updates might be slow at times.

I hope to add some more info on this during the coming days.

Black Level Measurements of Asian Displays

anfieldude — Sun, 27 Mar 2011 19:14:55 +0800

This thread is to document the black level measurements of the various displays that I have measured black levels in Malaysia/Singapore or anywhere in Asia

My equipment:

For the purposes of black level measurements I will use the following

1. X-Rite Chroma 5E
Specs : 0.02cd/m2 - 1000cd/m2
(0.006ft/L - 291ft/L)

2. Klein K-10
Measurement Range:
0.00006-2919 fL; 0.0002-10,000 cd/m2

cd/m2 - Candela/meter2
ft/L - foot Lamberts

I also own a EyeOne Pro Spectrophotometer that is used for calibration but not suitable for black level measurements.

The lower the number indicates lower black levels (better). These measurements are for a full/window black 0% IRE signal. As I get ANSI contrast measurements, I will add to this thread.

Plasma

Pioneer 428XG (2000hrs) - 0.009ft/L
Pioneer 428XG (2200hrs) - 0.011ft/L (ANSI Method)
Pioneer 508XG (~3000hrs) - 0.008ft/L
KRP600M (1200hrs) - 0.0013ft/L
KRP600M (1500hrs) - 0.0025ft/L (ANSI Method)

Panasonic 50VT20 (200+hrs) - 0.005ft/L
Panasonic 50V20 (1500hrs) - 0.009ft/L
Panasonic 50U20 (1200hrs) - 0.024ft/L
Panasonic 42X10 (2000hrs) - 0.08ft/L
Panasonic 42U30 (500hrs) - 0.032ft/L

Panasonic 65VT50 - 0.0025ft/L (THX Modes)
- 0.0033ft/L (ANSI - THX Mode)
- 0.006ft/L (Pro Modes)
- 0.006ft/L (ANSI - ProMode)
Panasonic 65ST50 - 0.0028ft/L (TrueCinema Mode)
- 0.0033ft/L (ANSI)

Samsung 50C650 ~500hrs - 0.06ft/L (0.12ft/L with Cinema Smooth on)

Edit: Added xx50 measurements

Display Calibration Fundamentals : My Take

anfieldude — Tue, 23 Mar 2010 08:12:44 +0800

A Beginner’s Guide to Display Calibration

This guide is work in progress. I will update with pictures as time goes by, please be patient.

What is Calibration?

Calibrate - To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument)

Calibration - The act or process of calibrating or the state of being calibrated.

Display calibration is centred on calibration of your display to standards.

Movie studios/directors adhere to standards when mastering movies/films.

One key feature of the standards for movies (colour) is the white point. The reference white point is defined as D65 for both North American and European standards. The white point refers to an x,y coordinate of 0.3127, 0.329 in the CIE Chromacity chart. CIE(Commission Internationale de l’Eclairage) is the international body responsible for the measurement of color.

6500K however, is a measure of the correlated colour temperature (CCT) of the white. Where D65 specifically targets a white point, the colour temperature is slightly misleading. It is possible to have a white that is 6500K in colour temperature (as it depends on whether the red and the blue channels primarily) but not hitting D65 white. For all practical purposes, D65 is a better representation of calibrating to a standard as if you do hit the 0.3127, 0.329, you automatically hit 6500K CCT.

The different standards that are available out there are:
· ITU-R Recommendation BT.709 (“Rec. 709”) – the standard for both North American and European high definition television - HD
· ITU-R Recommendation BT.601 (“Rec. 601”) and SMPTE-C – the standard for NTSC 480i/60Hz standard definition television (SMPTE-C has supplanted Rec. 601), and
· PAL/SECAM – the standard defined by the European Broadcasting Union (EBU) for 576i/50Hz standard definition television.

Once a display is calibrated to these standards (or as close to these standards as your display will allow) you do not need to wonder if the picture is accurate and tweak your settings for every movie. If your post calibration results are good, the pictures that you are viewing are as close to what the director intended for you to see.

2009/2010 Projector Discussion/Reviews

anfieldude — Fri, 23 Oct 2009 19:02:37 +0800

2009/2010 sees many new projectors being released.

In the coming months, I believe JVC, Sharp, Panasonic, Optoma, Vivetek etc will be releasing or have released their new models.

Initial reviews are starting to trickle in.

Thought I would start a thread for the projector kakis to discuss on the new releases.

I will try to update the reviews with links in the 1st 2 posts. Then you guys can discuss away.

To kick it off:

Panasonic PT-AE4000 LCD Projector Review AV Forums

Excerpt from Review:

Conclusion

With its exclusive lens functions for cinemascope fans, along with an excellent calibrated performance combined with very decent black levels and image contrast, the PT-AE4000 offers exceptionally good images at its price point.

Vivitek-H9080FD-LED-DLP-Projector-Review AV Forum Review

Excerpt from Review:

Conclusion

One big plus point of the projector is that for a single chip DLP model the lack of any rainbow effect is great and not replacing the light source for 20k plus hours must also enter the overall equation. Calibrated performance for colour and greyscale are reference level with just a lack in absolute dynamic range and black levels slightly denting an otherwise excellent performance.
