“1. You mention HDR on the PF1500W. "would love another PF1500w for UHD and short throw". I could not find any mention of HDR on that projector. Can you explain? “
“3. Do any of LG's 1080P projectors support UHD input? I could not find any that do.”
, the PF1500w does not internally process UHD or HDR.
I bought three new PF1500w projectors for the cost of one Epson HC3800. If I could justify the purchase (LG’s one year warranty and price are the main deterrents) of a fourth PF1500w projector I would create a tile matrix (video wall) of two by two projectors using a MST (multi stream transport) or AMD Eyefinity video card.
To play UHD HDR on this theoretical system would require:
1. An UDH / HDR source
2. A device to process the signal from that source
3. A display device to see the UHD/HDR image.
It appears to me that HDR is the hook to get people to upgrade from FHD 1080. When I posted my 3000 hrs and 200 inch thread, I did so because I was pretty stunned to find I had a richly saturated picture and that I could not see the pixels until I was about a meter from the wall with reading glasses. Not only that but as I read reviews about HDR images it seemed that the lamp based projector’s high lumen measurements on were drastically lowered in order to meet the saturation that HDR demands. I concluded that I was not in a hurry to upgrade to UHD especially since 8K is knocking at the door.
So I focused on a simple two projector solution with the ability to play bright and highly saturated images.
1. I downloaded UHD/HDR demo images from a google search on the internet which I converted to 1080p HDR10 using Handbrake 1.22 (x64 bit).
2. I downloaded madVR (there’s an entire forum threat on this forum) and later I chose K-lite Mega codec package which includes madVR to simplify the playback process.
3. I set the player to render madVR images, sat back and was blown away as I watched those demo images.
4. The computer and demos provided the images necessary to enjoy HDR on all of my PF1500 projectors.
5. If you want to get a feel for what I see then you could follow the steps above but note that it may be difficult to download demos and the process to convert a couple minutes UHD /HDR took me all day (as in 24 hours using a faster re-encode option) to 1080 HDR10.
6. To get a rough sense of the brightness of my PF1500 and PF1500w layered output on 130 inches display you would have to shrink the original PF1500 to 60 inches in low power and play the 1080 HDR10 demo.
“2. You mention improved picture quality on the internal apps. I have forgotten how to get into the control system in that mode in order to make sure I have Esegan's latest settings. Do you remember how to get there?”
When you use the Picture Wizard III it stores its results in “Expert 1” picture mode. I keep Esegan's settings in “Expert 2”. Note that when you use “Picture Wizard III” it puts the projector in “Minimum” power savings mode. After I use it, I immediately switch to “Maximum” power savings mode.
The “internal apps” to which I was referring was the internal media player. If you have a video file you can play it through your computer but you can also use the internal video player. The internal player seems to work miracles on some difficult files. Some trailers that appear as a muddy mess have been transformed using the internal media player.
If you find the time to experiment with computer based HDR video playback on any your video projectors I think you will find the results well worth it. I speculate that the extra color saturation of the PF1500 playing HDR demos will pull details from the shadows that you did not expect.
