When you use the P3 LUT, can you tell what colorspace the projector is in? It should be in SDR BT2020. For my LG projector, the info button tells me the projector’s current colorspace ie BT2020. I would know it is SDR, otherwise the HDR logo would come up.
I use the HDFury Vertex2 for LLDV. It is much more expensive but has multiple inputs and two
HDMI outputs. I use one to MadVR and the other straight through to projector. Best of all, I can control it with Alexa through the Harmony Hub
I didn’t take a look at projector info, will try this weekend when I have time. Not sure Epson got the info page like LG or not.
Initially I’d like to go for HDFury too, but then I watch the above YouTube video on building madVR PC, the YouTuber is using this small box, thus I gave it a try.
This splitter has a lot of discussion on AVSForum too, I remember multiple input version also available, but for me this one fits the best, as I only use sole source of Oppo 203.

You are most welcome bro!
For MadVR, the splitter is perfect because we drive the HTPC with HDR and MadVR tone maps to SDR for the projector.
However, in @Cash case, if you are using it to get LLDV to an OLED directly, some of these splitters are unable to trigger HDR mode on the OLED, requiring some fiddling with the LG OLED service remote. JVC projector owners are able to force HDR using the regular remote.
Putting the display into HDR is something the HDFury devices do in addition to presenting the LLDV EDID, which is what the splitter does. Also, HDFury devices can alter LLDV parameters such as target nits. The splitters usually fix these LLDV parameters although you can sometimes reflash the firmware to different target nits.
Changing the target LLDV nits is useful to match the display to the tone mapping in the LLDV algorithm. I have HD Fury on an OLED where target nits are 800, whereas on projectors, I use 100. With MadVR, it seems to work well set to 1,000.
What is your connection path? Mine is
Player->Vertex2-Out1>MadVR->projector HDMI1
The Vertex2 splits audio and sends it to AVR via an audio HDMI output. I put a 220ms delay on the AVR
To bypass MadVR
Player->Vertex2-Out2->AVR->projector HDMI2
This allows me to toggle between HDMI1 and HDMI2 to compare MadVR with straight through, wile maintaining correct audio sync
mine is really simple:
For video: 203 HDMI 1 —> splitter —> black magic mini 4K recorder —> madVR —> projector
For audio: 203 HDMI 2 —> anthem AVR
I didn’t set delay for audio as I didn’t see a sync issue
Hi guys
Just built my new rig
Have followed the steps for installing Madvr and video Processor.
The issue i have is the audio sync is out and the frame rate is not that smooth
I’ve Even delayed my AVR sync to 240ms
It gets close but still off?
Any suggestions?
Thanks in advanced.
Gear im running:
Cpu: i5 13600k
Gpu: 4080
MB: Gigabyte z690
Ram: 32gb
Case:Fractal North
Os: windows 11
Blackmagic 4k mini Recorder
MadVr: latest version with 116 added files
Video processor: latest version
Vertex2.
Set up is From.
Shield, Vertex2, MadVr, Projector.

What is your source? Some sources like Firestick, you can add additional delay
When you hit CTRL-J, are you getting any frame drops? Do you see stuttering
What is your route from source to MadVR PC? Is it source->avr->MadVR->display?
Are you using the default options of have you turned on the advanced options?
Did you enable Vertical Sync in the Nvidia control panel?
Hi sammy
The source is shield >Vertex2>split audio to AVR picture>Madvr>projector
I have followed the steps that “the casual cinephile” on youtube did in his build.
I have V sync turned on in the Nvidia settings
Nvidia shield set to 24hz
I’ve delayed the audio sync on the AVR to 180ms max i can go is (250ms) on my AVR
I will get some screen shots when i get home later today with all the settings i have .
Thanks sammy.
I have this.
Firestick->Vertex2
Vertex2 Out1->MadVR->HDMI1 on Projector
Vertex2 HDMI audio out->Denon X3800H
I set 220ms audio delay on Denon. Most people are around 220-230ms from what I have read.
I also connect
Vertex2 Out2->Denon X3800H->HDMI2 on Projector. It helps me A/B with MadVR or without.
Your Nvidia card is much faster than mine.
Hardware wise is OK, but the key question is whether or not there is a free 4x PCI slot to install the Decklink Mini. For the Invader PC cheap builds, the RYZEN ones didn’t have a free PCI slot or it was only 1x. However the Intel builds had one.

Has anyone compared the difference between MadVR vs straight out from the blu-ray player?
Depends on the display device. For a bright 1,000 nit OLED or Quantum dot LED, there isn’t much difference. But for a 100 nit projector, it’s huge.
my >5 years old Epson TW8300 can’t watch HDR/DV movies at all, with madVR, I’m now able to enjoy them completely, without investing on a new projector.
I believe you can tell which are with and without madVR below:
Bro must try and play a SDR source video file to compare. Don’t play a hdr file being stripped of its metadata and compare, it will naturally look like that because of the incorrect colour space.
So if u have a SDR video of oblivion, and a hdr video of oblivion movie, play the SDR movie and take a pic, then play the UHD video and take a pic… that should show how much madvr is doing …
U must compare the SDR version vs UHD version with madvr…
