As someone who's tv was received in the same condition I will tell you that the screen just looks like a hot mess when turned off and if I have my makeshift curtains drawn. Of course I haven't wiped it down with the microfiber that was suggested to me yet. When mine is on I have none of the issues you described though. I will say, don't, I repeat...DON'T use alcohol in any form to clean the screen. Someone else posted a link to how to properly clean it a few pages back. I know that I didn't realize that when I had to clean off the glue residue from the yellow sticker when I got mine. Thankfully it was just a small spot though. Regardless, that will damage or remove your anti-glare film. Also make sure you clean unplugged and give it enough time to cool down. As far as how things look, we need a bit more information here.
Can you post a picture of your settings? Because without out some of that information I don't know how anyone can help. I can tell you that I have my eco none sense off and use the movie picture default settings on just about everything I do on mine, even gaming. I've only tweaked a few things based on what I've read in the thread and what looks good to me. The minimal light bleed seems to vary. I know that when I initially got mine I didn't notice it as much and sometimes feel like one of the firmware updates made it more pronounced on mine. I tend to play around with my tilt a bit, which helps. I'm afraid outside of that, I don't know what to tell you? Outside of mounting the tv I rely on the advice of the other owners or my eyes.
You know, I ran into the audio drop out on my receiver coincidentally after the 1154 update. I think my flag of help post was drowned out by the ad debacle and I had to work it out on my own. I have no idea what particular thing fixed the issue, but I did the usual suspects. Hold down the power button until the UHD logo pops up might fix the channel guides? I think the one that really fixed the audio drop out though was unplugging it with the power on and clicking on the power button 10-15 times on the remote. Then I let it sit for about 5-10 minutes?
This is actually a perfect example of what frustrates some of more seasoned owners and why we sometimes tend to ignore posts or get snippy. I mean, do you go to the doctor and say I've got a pain? No, you can't even get an appointment without being drilled by the receptionists or nurse on what is going on. So do us a favor and post your picture and other settings when you have a problem. Stop making generalized posts and expecting people to know how to fix your problem as if we can read your mind.
Again, we need more specifics. Is it the PS4 or PS4 Pro, what type of receiver do you have? Need all of the information before we diagnose what is going on or can point you in the right direction. For example, I have my Xbox One and 360 hooked up to my OCB HDMI4 Arc directly because they neither technical produce HD audio to my Onkyo HT-S5300 receiver. My KS8000 HDMI Audio Format is bitstream and Audio Format is Dolby Digital (as is my Xbox One).
