Luma 500 playback image quality problem

[Yang]

I have a Luma 500 DVR inherited from previous owner. The issue I encountered seems to be extremely basic. Hope someone can give me some clue where to look at.

1. I can use the very old IE to log into the device and do everything I want. The problem is IE is so old and out of support from Microsoft. When I try some modern browsers, I got an error said failed to detect plug in. Besides IE, is there any browser supported using PC?

2. I prefer to use PC to operate Luma. So I downloaded Luma VMS software and in a hope that I can avoid using IE. Luma VMS seems to cover all the features browers provided but the problem I encountered is the playback image quality is bad. I attached two sample images that shows playback from IE and Luma VMS. Do I miss any settings that can improve Luma VMS playback? The weird thing is the live view on VMS software looks good and matches IE. Only Remote Playback is bad.

Some update on this troubleshooting. 

I noticed on Luma Phone app, when playing back videos, it has an option to toggle high resolution or medium resolution videos. If I set to high, the video looks beautiful.

Both Luma VMS PC software and Luma Phone app connect to port 8000. Since phone app works, I would assume the problem is on the PC software.

My understanding is Luma VMS somehow decided to use the low resolution stream to play back the video. Somehow I need a way to change it to use high resolution stream.

After carefully reading Luma VMS manual, I noticed the following description in the camera group setting under manage device tab: "Playback Stream Type: Select the stream for the playback of
the camera. This only displays if it supports dual-stream."

Looks like it does have a way to enable high resolution stream for playback.

Now, the problem is that selection of Playback Stream Type did not even show up!

I am not sure if this is a bug on VMS software.
