I just hooked up my new Oppo 203 last night to the my G90. I made some blanking adjustment (overshooting the screen at the top) and when I finished I noticed a white line/band a few inches above the picture. It maybe a couple scanning lines. The screen is hanging a third of the way into the room (integrating HT into a formerly dedicated 2 channel set up) and has a black felt border a few inches wide. The lines just hits the top of the black so it's possible it's been like that since Kurt came down and set the thing up and it the line was shooting off into the room. Anyone have any ideas how to resolve this?

Edit: What should the resolution be set at? 1080p 24/50/60 or 1080p auto. Currently it is set at 60. Can somebody give me a quick primer on the advantages and disadvantages of each? Lastly, there is a "Target Luminance" setting the has the units "nits". Some help here would be much appreciated.

1080P 60 or 720P 60
See what you like best. The error might be gone in 720P

Turn OFF "HDR" from Auto. Must be turned to SDR.
That's what the nits slider is for, simulated HDR called tone mapping, then in the Oppo.

HDR is set to Auto on mine. Other settings gave a under saturrated picture.

You can also slide the nits control when HDR is set to Auto.

I personally use 250-300 nits and Mode 3 on HDR-SDR mapping.

Personal I will recommend that it will be better with HDR turned off.

On your G90 you don't have BT2020 or HDR I think it will be better to turn HDR off completely.
Then you get standard dynamic range with Rec709. Your G90 will never reach BT2020 anyway as you know.

The nits setting slider works like this, more punch in the picture lower nits less punch higher nits. "In highlights"

To low setting will burn out in white, and to high setting will make black crush.

I will say here try it out and pick the best setting that you feel is right for your display. Last time I checked on my display 150 was okay.

What is the best way to do is to look at the Blu-Ray version of the movie, and then compare to the UHD version of the movie to get it as close as possible, then what you see in white and black. To get it best way possible a calibration.

I actually have a similar white line at the top of the raster on my VPH-1272Q. For some reason it never ocurred to me that there might be a way to get rid of it. I'll be following this thread.
