I suppose I should at least do a preliminary power on test before ceiling mounting it. Seems like the built in test pattern is the best way to do this? It looks like people have been observing color gradient issues in the test pattern ( see posts above ). That will probably be my first test.
I have my refurb 5040UB all set up now. It did have a slight LCD alignment issue. When using the PC, I could see a green horizontal line on the bottom of an all white window in WIN10. I did the 'panel alignment' process via the projector settings and after messing with it a couple hours, the green line no longer appears and I am now happy with it.
I tried a few of the calibration setting posted on the main 5040UB thread and then tried out a few 4K NON-HDR videos on YouTube. The picture is absolutely amazing!
Coming from a midrange 1080p DLP projector, I now understand what I was missing out on till now.
I then tried switching HDR on in the WIN10 settings...and started having problems. The same 4K videos that worked fine in non-HDR mode now stutter when viewed in HDR mode. It looks to me like this is a common problem. Frankly, HDR in general seems like a mess on the PC side. I did find the following discussion on HDR, etc...that was quite educational for me :
There are lots of options as far as HDR is concerned...I would encourage other newbies like me to go to the discussion above and read up.
I may try to set things up in the discussion above to see if I can solve my 4K HDR stutter on PC issue. If anyone has any other ideas, please let me know!
Well crud...I figured it out. According to the chart below, my Nvidia GTX 1070 won't handle 10bit VP9...which YouTube apparently uses for HDR content. Interestingly enough, the Nvidia GTX 1050 *does* support it...probably because the 1050 was released after the 1070 and has an improved decode chipset (?) Gee, confusing enough?
I guess a new graphics card is in my future at some point....
