Epson Tw700 - Pana S97 - 10m Ugly Hdmi Cable No Workey

[funkybits]

Howdy,

I have an Epson TW700 Projector fed via a Panasonic S97 DVD Player.

I used to have the PJ sitting on a coffee table using a 7m Selby HDMI cable which worked 100% AOK.

I have just mounted the PJ at the back of the room on a wall shelf and bought an Ugly Brand 10m HDMI to HDMI Cable from ebay and I can't get a picture when I use it. I have tried all HDMi settings on the Panasonic & PJ ( Extended colour space, RGB, YPR 4:4:4 , YPR 4:4:2 and always receive the message "Not Supported" when I select HDMI on the Projector.

Has anyone else had any problems with Ugly cables as the Selby one worked aok ?

Cheers in hope

Johnno

Not surprising to be honest - HDMI is rapidly becoming 'Hate DMI' in installer circles... Could be either of the following:

1. Faulty Cable

2. Handshake HDCP issue or 'snyc' issue. This happens a lot - especially over longer runs - meaning anything over about 9 metres. I have seen a 50K Runco refuse to handshake with a 5k DVD player over a 10metre run of HDMI. Nothing could make it work - except changing the cable *shrug -*

Try a different HDMI cable is your best option.

Forgot to add - I have quite a lot of sucess with AudioQuest HDMI cables for HD 1080p up to 10 metres and Kordze HDMI for lower rez up to about 20 metres. The Kordz are also relativley inexpensive - compared to the AudioQuest anyway.

[Hydrology]

The Kordz would be my choice, and will work up to 40 meters (1080P). Bit more than your Selby, but not as expensive as AudioQuest.

[JoshH]

The Kordz would be my choice, and will work up to 40 meters (1080P).

NO WAY.

It will work up to 40 metres carrying 720p [maybee] - but no way will it carry 1080p more than about 10metres. Even the very best HDMI cables only carry 1080p up to about 10 metres under 1.2 spec.

you can use an active booster from audioquest or similar to extend 1080p travel to about 20 metres under 1.2 spec - MAX.

Spec. 1.3 allows for longer distance but I am not aware of HDMI cables on the market that actually meet this spec as yet. If there are please show me as I would really like to know.

The Kordz are really good value for money - but they definately dont carry 1080p 40 metres.

I have a really really good article on HDMI by audioquest that talks about the significant difference between running 720p or less and 1080p in pdf format. If you want it pm me and I will forward it to you. It affirms my experience in the field running 1080p - but more importantly it describes the differences between the specs. I found it really informative.

HDMI 1.3 Demystified

Xiaozheng Lu, Senior Vice President, Product Development, AudioQuest

The release of the new HDMI 1.3 specification on 6/22/2006 created both

excitement and confusion in the consumer electronics industry. The discussion

below is provided to help clarify this new technology and provide you with a better

understanding of what you need to know when buying or selling HDMI products.

What is HDMI?

High-Definition Multimedia Interface, or HDMI, is a digital audio, video and control

signal format defined by 7 of the largest consumer electronics manufacturers.

Released on 12/9/2002, it is supported by more than 300 companies. The

advantages HDMI has over other signal formats are:

• Uncompressed digital signals for the highest picture and sound quality

• One cable for video, audio and control signals

• Two-way communication for easy system control

• Automatic display and source matching for resolution, format and aspect ratio

• PC compatibility

What’s new in HDMI 1.3?

• Higher speed: max data rate doubled from 5 to 10 Gbps

• Deeper color: color depth increased from 24 bit to 30, 36 or 48 bit, for smoother

pictures

• Wider color space: the range of colors widened to all colors human can see

• Supports lossless audio formats: Dolby TrueHD, DTS-HD Master and more

• Lip sync: sync audio and video, compensates for signal processing delays

• New mini plug: Type C for portable devices like camcorders, in addition to the

current Type A and B

Want to know more?

Read on. You don’t have to understand all the technical terms here in order to grasp

the overall concepts.

All the signals travel inside one HDMI cable:

• 4 TMDS (Transition Minimized Differential Signaling) signals over 4 twisted pair

wires, including 3 digital video signals (RGB or YCrCb) and 1 clock signal; the

digital audio signals are also multiplexed into the digital video signals. The Dual-

Link HDMI has 3 more twisted pair wires for digital video signals to achieve

higher data rate.

• DDC (Display Data Channel) data and clock lines carry the two-way

communication signals; the HDCP (High-bandwidth Digital Content Protection)

signal also floats here.

• CEC (Consumer Electronics Control) data line distributes remote control signals

for one touch system controls.

• HPD (Hot Plug Detection) allows the source to detect a display plugged in real

time.

• +5 V power line supports remote circuits for communication even when the

power is not turned on.

Video signal resolution and data rate

• Resolution: refers to how many pixels in horizontal and vertical direction per

frame. 720p has a resolution of 1280x720, while both the 1080i and 1080p are

1920x1080.

• Refresh rate: refers to how many frames or fields of pictures per second. The

common rates are 30 and 60 Hz in the US, or 25 and 50 Hz in Europe.

• Color depth: refers to how many bits of data needed to encode each pixel.

Common ones are 24, 30, 36 and 48 bits.

• Data rate: refers to total number of digital bits in a second for a given signal. It’s

roughly the multiplication of all the 3 numbers above together. So, the higher the

resolution, refresh rate, color depth, the higher the data rate. The max data rate

for HDMI 1.0 thru 1.2 is 5 Gbps, while the new HDMI 1.3 max is 10 Gbps.

Type of plugs and Single-Link / Dual-Link

• Type A plug: the most common HDMI plug, 13.9 mm wide, 19 pins, designed

with one set digital video TMDS lines (Single-Link)

• Type B plug: the seldom used HDMI plug, 21.2 mm wide, 29 pins, designed with

two sets of digital video TMDS lines (Dual-Link) for higher data rates

• Type C plug: the new mini HDMI plug, 10.4 mm wide, 19 pins, designed with one

set of digital video lines (Single-Link) for small portable devices

• Single-Link HDMI uses one set of digital video TMDS lines to carry lower data

rate signals using cable with at least 15 conductors

• Dual-Link HDMI uses two sets of digital video TMDS lines to carry higher data

rate signals using cable with at least 22 conductors

Before HDMI 1.3, the Single-Link was good for 5 Gbps; the Dual-Link could handle

10 Gbps. HDMI 1.3 changed that, now the Single can carry 10 Gbps, the Dual even

more. This change raised more questions and confusion than anything else.

Type of HDMI cables

For the first time, HDMI 1.3 specification divided the HDMI cables into two

categories:

• Category 1 or Cat 1 cable: can carry signal with max pixel clock of 74.25 MHz

(roughly equivalent to data rate of 2.2 Gbps)

• Category 2 or Cat 2 cable: can carry signal with pixel clock greater than 74.25

MHz (roughly equivalent to data rate of 2.2 Gbps)

All the HDMI cables made before HDMI 1.3 published are at least HDMI Cat 1

compliant.

How far can an HDMI signal be transmitted over a cable?

This is a complex question. The max length for an HDMI cable to transmit a usable

HDMI signal depends on the entire system: the source device performance, the

display performance, the signal data rate, and the cable performance and length.

The higher the signal data rate, the shorter the maximum usable cable length. If a 5

Gbps HDMI signal can go as far as 10 m (33ft) on a given cable, a 10 Gbps HDMI

signal can only travel for 5 m (16.5ft) on the same type of cable.

All HDMI cables made prior to enactment of HDMI 1.3 will pass HDMI 1.3

signals, but only half as far for data which is sent at the MAX rate. Keep in

mind that HDMI 1.3 only EXTENDS the max allowable signal data rate; it does

not INCREASE the data rate of a given signal. Your cable will still run the same

distance on the same 1080p signal regardless of whether the devices are HDMI

1.2 or 1.3. The maximum distance will be reduced when you run the higher data

rate signals now made possible by HDMI 1.3.HDMI extender (repeater, amplifier) compatibility with HDMI 1.3

Unlike cables, most of the IC chips used in electronic HDMI extenders have a hard

cut max data rate. So the extenders made before HDMI 1.3 published most likely

won’t work with the HDMI 1.3 signals with data rate higher than 5 Gbps.

Lip Sync

Modern AV devices have many signal processing features. Most processing causes

signal delays. Usually the video processing has a longer delay than the audio

processing, causing the picture and sound to be out of synch. HDMI 1.3 added

communications via the DDC line to allow the source to adjust the audio delay based

on the video-audio mismatches reported by the down stream devices. This solved

the lip sync problem. All HDMI cables made before HDMI 1.3 published can

support Lip Sync features because the inserted data is part of the DDC line.

Summary

In most cases, you don’t need to worry about the evolution from HDMI 1.2 to HDMI

1.3. Like most new technologies, HDMI 1.3 is backwards compatible. Also, most of

the HDMI devices have DDC communication capability. If any device is not HDMI

1.3 compliant, the whole system will fall back to HDMI 1.2 or lower to ensure

compatibility through the DDC communication. The only time you may have

compatibility issues with HDMI 1.3 is when one of the devices is not HDMI 1.3

compliant, and it does not “speak up” (no DDC communication capability, like many

extenders, distribution amplifiers), or if the cable length is too long, AND you are

running a signal higher than 1080p 30 Hz.

Hopefully, this has served to clarify your understanding of the many facts of HDMI.

Thanks for all the comments. Going to see if I can get a refund for the Cable and might see if I can get a Kordz.

Let me know how you go as I just bought the same cord as you and really am hoping that it works. If not I will be looking for a refund as well.

[Hydrology]

I can confirm that the Kordz Silver Diamond 35m and 40m WORK with 1080p. They have been certified by HDMI.org to work and have inbuilt active repeaters (two in the 40m). Of course YMMV. I always found AudioQuest to be a higher tiered Monster brand. I respect Monster and AudioQuest as brands but price v performance they do not represent value for money.

NO WAY.

It will work up to 40 metres carrying 720p [maybee] - but no way will it carry 1080p more than about 10metres. Even the very best HDMI cables only carry 1080p up to about 10 metres under 1.2 spec.

I really have found that the audioquest significantly outperform the Kordz - but regularly use Kordz as an excellent value for money cable.

But thats kewl - each to their own.

I have a 10m Ugly brand HDMI cable from Yamaha RX-V 2700 amp to sanyo Z4 projector working fine. The build quality of the cable looks good.

Cheers Bill

The Kordz would be my choice, and will work up to 40 meters (1080P). Bit more than your Selby, but not as expensive as AudioQuest.

I have bought 15 metre Advance-connect HDMI cable from Sterlingtek.com and it works fine for my set up of Sony VW50 and DVDO VP50.

They are about 40% the cost of Kordz cable.

I just got my Ugly cable last night and although I have only used it for 3 hours it looks fine. It's 10m in length going from my pioneer amp to my projector. Will let you know if any problems occur but overall I am very happy.
