Ovako, imam na grafickoj karti 2xDVI izlaz i jedan HDMI izlaz, e sad htedoh da povezem sa LCD TV-om, jedini problem je sto su poprilicno udaljeni, oko 17m. Sad pitanje je, da li ce doci do gubitka u kvalitetu pri toj razdaljini (ako gledam HD filmove) i ako hoce da li onda postoji neko resenje povezivanja (najbolje putem LAN konekcije)?
Ja bih, na tvome mestu da sam, rizikovao. Tako su i meni tvrdili...

neki iskusni rtv majstori kada sam, davno, davno, povezivao stand alone DVD player sa tv-om (S-video, chinch). I sta je bilo? Povezao sam ih AUDIO (interconnect) kablom dugackim desetak metara. Kvalitet? Odokativno ocenjeno - no change u odnosu na ono sto dobijam kada iste uredjaje povezem putem antenskog (75 Ohm, koaksijalni) kabla dugackog 2m... I sta kaze majstor kada ovo cuje? DA LI SI NORMALAN - to je nemoguce, tu slike ne moze da bude! A onda dodje, uveri se da MOZE i u neverici vrti glavom...
Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable`s construction quality and conducting materials) limits usable lengths in practice.[65] HDMI 1.3 defines two cable categories: Category 1-certified cables, which have been tested at 74.5 MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340 MHz (which would include resolutions such as 1080p60 and 2160p30).[62][66][67] Category 1 HDMI cables are marketed as `Standard` and Category 2 HDMI cables as `High Speed`.[1] This labeling guideline for HDMI cables went into effect on October 17, 2008.[68][69] Category 1 and 2 cables can either meet the required parameter specifications for interpair skew, far-end crosstalk, attenuation and differential impedance, or they can meet the required nonequalized/equalized eye diagram requirements.[66] A cable of about 5 meters (16 ft) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081 mm²) conductors.[65] With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, an HDMI cable can reach lengths of up to 15 meters (49 ft).[65] Many HDMI cables under 5 meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work.[70]
As of the HDMI 1.4 specification, these are the following cable types defined for HDMI in general:[71][72]
The maximum length of DVI cables is not included in the specification since it is dependent on the pixel clock frequency, and hence the video mode`s bandwidth requirements (which is a function of resolution and refresh rate). In general, cable lengths up to 4.5 m (15 ft) will work for displays at resolutions of 1,920 × 1,200. This resolution will work even up to 10 m (33 ft) if appropriate cable is used. Cable lengths up to 15 m (50 ft) can be used with displays at resolutions up to 1,280 × 1,024. For longer distances, the use of a DVI booster is recommended to mitigate signal degradation. DVI boosters may use an external power supply.
