for the A10, can we use Astro Go with this unit?

i just got the Egreat A5 and i am facing several issues

1. when i use 4K24, i could not select YCBCR 4:4:4 10 bit. i am only allow to use 10bit wheni view 1080P resolution. any way to select 10bit for 4K?

2. i encounter micro stuttering when i play certain files especially 10bit encoding files. all files and played using USB3.0 external hdd. Anyone facing similar issue?

3. The player would hang when i try the option (Force 3D)

Anyone is facing such problem?

i am using the beta firmware 1.2.3.9.

Bro...thanks for the reply.

i think i will go with the YCBCR420 10 Bit. i agree that we would not lose much by using 4:2:0 as all 4k Blu ray are coded in 4:2:0 sampling anyway.

i will try out the auto frame adaptation later tonight and see if it works.

another problem i face is the image is much darker when i play 4k HDR BDMV compares to 1080P BDMV.

my JVC supports HDR and i tried the projector using OPPO and it doesnt have this problem. is the Himedia image darker when you view HDR material?

understood....

then should be that issue because i dont find this issue watching Netflix HDR or original Bluray

HDR looks fine on Netflix and PS4 pro game but not with ripped files. I think this is due to the security issue.

When i watch 4K files, i need to switch it to SDR but it defeats the purpose of UHD iso/BDMV if we cant enjoy HDR.

this Egreat A5 is actually giving me quite a big headache.

When i want to use YCBCR420 10bit, it tells me that only 4k50 or 4k60 supports it but somehow when i switch to 4k50, it tells me that YCBCR420 10 bit is not supported.

i need the 10bit as the 8bit color banding is quite obvious. this is not very noticeable with my 50" LED but its very irritating when its on large screen projector.

i cant do both the setting.

so far no other forum has mentioned any of this regarding the Egreat A5. Probably have to wait for the new firmware. quite frustrating.

i have managed to solve the 4k HDR image quality. i bought the Spyder 5 to calibrate as the JVR comes with its own calibration software by laptop.

i downloaded the custom gamma curve for HDR and it improves the quality drastically.

once the custom gamma curve is in place and the color fully calibrated with the Sypder, the image looks stunning.

i have also managed to run 4:2:0 10bit quality. the problem was with the Yamaha A3060 4K mode. it was set to mode 2 therefore the 10bit was not supported but once i changed it to Mode 1, it solved the problem.

somehow this Mode 1, it does not work with my Ps4Pro. my headache now is that i need to manually switch to mode 2 whenever i use my PS4 pro.

as for the 4K HDR BDMV, the unit supports full BD Menu and the 3D works too. The menu support was the main reason i bought the EGreat A5.

4k HDR will definitely be slightly darker than 1080P movie in some way.

the article above will clear up some confusion regarding image being darker. in a way, the total dynamic range has been increase thus seeing more details.

this however can be reduced by having the TV calibrated. i calibrated my JVC projector with Sypder 5 with a custom Gamma curve. the gamma curve of REC709 and BT2020 is very different therefore using a custom gamma curve would helped improved the image drastically for HDR 4K. using the linear line gamma would produced a very dull image with overexposed image and the dark areas are very grey instead of black thus creating a very 2D image with less pop in the overall effect.

as for the issue of the PS4Pro not able to handle HDR with Yamaha, i realized the problem is due to the Wireworld HDMI cable. the 12m active cable is rated at hdmi 2.0 with 18gbps but it failed to deliver HDR at 4:4:4@60hz. the image just failed to be display on my projector. when i changed to the audioquest, it solved the problem but it will have intermittent signal issue. if you plan to use >12m cable, i would suggest going for HDMI Optical cable instead.
