SN75DP130: Best solution for TMDS replicating (1:2), DP130 or TMDS442?

Hi,

We need a solution for HDMI (replicating) -- one source video displayed on two monitors SIMULTANEOUSLY. We have the option of going *DP to HDMI* or *DVI to HDMI*.

After browsing through the e2e forums, the best options at this time seem to be using one of the three ICs below. Any guidance or direction regarding these options is appreciated. Also, if any other options exist please suggest.

1) SN75DP130 (1:1 redriver) -- two chips used in parallel, set to TMDS mode. Paralleling degrades the source signal but the redrivers then correct this?
2) TMDS442 (4:2 switch) -- single chip used, but source signal is paralleled to two separate inputs. Source signal is degraded with no correction?
3) TMDS181 (HDMI retimer) -- two chips used in parallel. Video source and clock are corrected. Are there any special considerations regarding this option?

At this point option #1 is preferred as it seems to be the most straightforward and least expensive. For all three options the plan is to have only one EEPROM for EDID..

Thanks in advance,
TD
