Righe rosse su 868

Non è assolutamente vero: io ho il tuo stesso lettore (Pio 868) e lo uso con un cavo DVI di 15 metri autocostruito, collegato a uno switch DVI a sua volta collegato al lettore con un cavo DVI/HDMI di 3 metri e mezzo (fai un po te il calcolo).
Non gli credere: o il cavo o il lettore sono difettosi.
Ciao,

Concordo in toto.. Anche io ho il Pio 868 è solo in 720p noto un lieve sfarfallio rosso a 1080i assolutamente nulla e dil cavo e di 10 metri più adattatore... E penso che il mio problema stia sopratutto nell'adattatore.....

Quella che il Pioneer ha un chip del "cavolo" è un emerita caxxata....

Vi posto la mail del tecnico del costruttore del cavo!!!

Dear Mr. xxxxxx,

first of all, we are very sorry to hear about your problems in the past
concerning your hardware-connection with OEHLBACH - HDMI / DVI cables.

As we heard your DVD-player is a Pioneer DV 668/868, please let us give you
some background information in this matter:

As we found out, there is a problem with the first generation of HDMI-ICs
which are used by the hardware-industry especially within the Pioneer-DVD
players 668 / 868. This problem was already discussed on the internet in
several foren and that's why there are companies in Germany which do
optimize the HDMI-output of Pioneer-DVD players to stabilize the HDMI
output. For example, company Benedictus www.benedictus.de does
customizations like that. Next generation of HDMI-IC's will be improved as
we were told from Benedictus.

Problems like the ones you have occur when using a Pioneer DV 668 / 868 in
combination with some sort of projectors that seem to be more "sensitive" in
this matter like for example plasma or TFT-screens are. This, in fact, is
not a problem of the cable. For example, we did also receive emails from
customers that own DENON's new DVD-3910 DVD player that work perfectly in
combination with our 20,0 m (!) cables; even though we are aware that this
does not help you out with your problem.

We checked all cables in the past and they worked in combination with our
Pioneer TFT panels without any problems; even with the highest resolution
setup.

Some more informations about HDMI / DVI cables:

The HDMI- and DVI-Standard uses an operating voltage of 3,3 Volt and there
is only a tolerance of +/- 5% accepted. In other words: even if the signal
drops down about a voltage of only 0,165 V, this might already cause a
failure of image formation. Especially when longer cables are used, due to
physical reasons, there is always a small amout of signal-loss caused by
resistance; even though OEHLBACH can keep those losses extremely low by
using only high - quality materials in OEHLBACH cables. A few hardware
components are quite sensitive to this - most of them are not.

Single-link cables like the HDMI/HDMI or HDMI/DVI cables support resolutions
up to max. 1400 x 1050. If you scale the resolution on the DVD-player-side
higher than 1400 x 1050, problems will occur.

Although the HDMI / DVI - standard supports digital signals only, every
single loss of any digital information - no matter what this loss is caused
by (either longer cable distances, transision-resistances or pretty close
tolerances of this standard), will end up visible. What I am trying to say
is, that scaling higher than the standard resolution from what the DVD
supports, means a lot more additional digital information which has to be
transported (2,2 times more information at 1280 x 720). Therefor it is
always better to scale higher resolution on the receiving unit (projector)
if possible than on the player side.

HDMI cables contain many inner conductors which are located by construction
very close together. This results in a relatively high capacity of the cable
itself. A few DVD-players do have problems with high-capacity cables; we
figuered out that TFT or plasma screens are obviously not sensitive in this
matter at all.

Well, after all this information, you probably ask yourself what can we do
to help you out in your special case!

Here are a couple of things for you to check that might get us closer to a
reasonable solution:

- Try to scale higher resolution only on the projector's side.

- When using a Pioneer DV 668 / 868 please try the 7,50 m version of the
cable, if your invironment allowes that.

- Think of getting the DV 668 / 868 player stabilized by one of the
companies that offer service like that (like for example www.benedictus.de
does).


Please give us your feedback so we can help you to find a satisfying
solution.

Dopo tante prove sono arrivato a una soluzione!!!
Il cavo che ho preso in precedenza purtroppo non e compatibile con il mio Pioneer, ho avuto modo di provarlo con un denon 3910, e non presenta il problema che ho io.
Comunque ho dovuto purtroppo mettere mano al portafoglio e ho preso un cavo G&BL hdmi-dvi da 10m (che funziona con il mio hardaware) La causa molto provabile e' che il pio ha una uscita non molto robusta che accopiato con il cavo in oggetto della discussione creava i problemi esposti nel tread.
Ringrazzio tutti quelli che sono intervenuti e che in qualche modo mi hanno aiutato.
Ora non mi resta che mettere in vendita il cavo a chi ha un Denon

Come è strana la vita è proprio il cavo con il quale a noi ha nn ha funzionato per nulla!....a questo sarà davvero stato ls110 l'anello debole del collegamento che nn digerisce segnali HDMI...eppure l'assistenza il sito Infocus...tutti certificavano la compatibilità...boo ki ci capisce pè bravo!
Salutoni.
