I have started to notice faults with my W2700 now. I never used to get the split screen issue, but over the past 8 days or so I've started to get it. It would only happen for 2-3 seconds while the resolution changed and then it would be fine. I also started to get a longer black screen when shows were starting on NF and also Blu-rays on the Sony X700. Then a couple of days later, the black screen would then flicker with a green/blue colour cast. Is this what others have experienced? I've also noticed the screen going black a couple of times when about 2 minutes into a show on NF. This is random and doesn't happen all the time. When I stop the show and play it again, it doesn't happen, so I can't intentionally reproduce it. I have updated the firmware to 01-101 and so far the green/blue colour cast has stopped, but the black screen still remains. The only thing I have changed hardware wise was to swap over my HDMI cable from Out Sub to Out Main on my Onkyo TX-NR636, and to upgrade to a full 4K 60Hz HDMI cable to go from the X700 to the receiver. I wouldn't have thought that a better HDMI cable would make things worse.
Also, when I'm watching Sky, the edges of people and objects distort/pixelate with random black parts when there is motion above a certain speed. The firmware update didn't fix it. Again, this could be down to the HDMI cable or using the other HDMI port on the receiver. I'm going to try and use the old basic cheapo cable again to see if it's that or not. I'll put the cable back into Sub Out and see if that fixes it as well. I've got until the 24th of this month if I want to send it back for a replacement or a refund, but I'm wary that if I get a replacement it'll be worse. I'll decide over the next few days after some more testing.
