TMDS181: Eye diagram problem

Part Number: TMDS181

One of our products uses TMDS181 as the output port for signal processing.
The eye pattern test of the current product failed.

1.PCB:

Our product actually uses DVI connector. The output of TMDS181 is connected to the DVI connector through a piece of PCB circuit.Below is the PCB layout for part of TMDS181.

The difference line TX2 has the worst eye (the yellow line in the figure above).
According to the test report provided by PCB manufacturer, differential characteristic impedance is 93.8 euros. Is the impedance deviation of -6 ohm the cause of this eye pattern?

2.The output eye of the product:

The eye after the DVI output socket is as follows (all components except the DVI socket on the difference line have been removed during the test) :

 

3.Output eye figure of TMDS181 chip:

In order to eliminate the influence of PCB impedance, I removed the PCB wire corresponding to TX2 pin and directly welded two 3mm long leads on the TX2 output pin of TMDS181 chip when testing the TMDS181 output eye diagram. 
Two 50 ohm resistors are then connected respectively to 3.3v (2 100 ohm parallel) to meet the requirements of DVI eye chart test (analog receiver 50 ohm pull-up resistor). Test PCB photos and eye pictures are as follows:

 

4.Eye of TMDS181 input:

TMDS181 input signal is from another chip on the same PCB. The clock is 162MHz and the data is 1.62GHz, so TMDS181 is in Retimer mode. The eye diagram of TMDS181 input terminal was taken out of the TMDS181 chip and then two 50 ohm pull-up resistors were welded on the PCB wiring of the input terminal. The graph is as follows:

 

6.Current Problem

Is the ringing in the eye diagram of the output of the chip caused by the fact that the 3mm lead I welded does not match the impedance?

 

The Layout of PCB may be the key problem for the abnormal output eye chart of the product.

In order to meet the difference line isometric, it is necessary to increase s-type wiring, but this may affect impedance matching.

Impedance matching and signal line equal-length, which is more important?

Can you help me with the impedance design of PCB? Thank you very much!
