Will have to wait for lockdown to get one of those transcoders.
Until then I’ve switched from:

Thanks for writing up these instructions, I feel the Wii ones are particularly important given the system’s software’s inconsistent approach to rendering its image, I’ve been gobsmacked by some of the photos you’ve shared of the pixel perfect output! It’s an eye-opener after years of upscaled blurry 16:9 component cable output from my 768p Bravia, much of which isn’t even correctly scaled due to third parties doing weird things (No More Heroes returns a squished image in widescreen…)
I eventually ended up at the following Combo:
Why?
480p out of a DC is different spec than 480p out of a Wii, in terms of sync and position. So passing these through unmodified means that after every input select I would also need to go into my TV menu and do an “adjust” so that it displays the image correctly. This gets annoying very quickly.
So I use an Extron to take care of that automatically: the single output always has the same sync and position regardless of the properties of the input signals. I never have to touch my display menu!
Summary
I have PS2 on Component into the GBSC. Output from the GBSC into the KVM along with DC, PC and 360. That means a single switchable source into the Extron.
Wii and Xbox join at this point straight into the Extron component input, only because they don’t really require scaling or deinterlacing. And I often have the Wii and PS2 powered on the same time.
Resulting single output is unified 480p over DVI to my display.
Hey Matt have you tried PS2, Xbox and GameCube on that EDTV? I would love to see some shots of your results even if they aren’t that great 
There are photos on here from myself and @Gravitone (who has the same TV), I’ll try to take some more soon.
But they are all pixel perfect (image centred with black borders depending on the game active area).
Dreamcast is full screen. Even though Wii is 480p games don’t use the whole area.
You can check out some of the shots I made in this thread:
Scroll through my Instagram to see some videos and photos of games running on this display. I can share the original files if there’s anything of interest.
Which VGA to DVI adapter is recommended for use with the DVI port on the 20PF4121/01 when connecting to the Wii.
On my 20PFL4122/10, the following setup worked well:
Wii > Mayflash to HDMI adapter > HDMI cable > HD Fury 2 adapter to VGA > VGA port of the TV.
The picture quality was great, in my opinion.
For the 20PF4121/01, I will be targeting the DVI port. I see two possibilities:
Do you have any recommendations? Should I go with the first or the second setup? Is there a quality solution similar to the HD Fury for the VGA to DVI adapter in the second setup?
Option 1 will give you digital video and it will be processed, not what we want.
Not sure about option 2, but it’s closer to what you want.
My method is: Wii > Component cable > GBS-Control (Component input > VGA output) > VGA cable > cheap DVI-A simple pin adapter > TV
The port on the TV is DVI-I (integrated, so does both Digital and Analogue) but we need to use analogue to get pixel perfect with zero processing.
Do you have a reason to include a Wii HDMI adapter? It certainly complicates your approach.
Hey Matt, thanks for responding. When I used the Component Cable with the Component input on the 4122, I was not satisfied. I don’t have a GBS Control to convert component to VGA, and I needed to connect my Wii signal to the HDMI input port of my HD Fury 2. That seemed to be the best solution for me. However, I will definitely consider your suggestion. Which GBS Control do you recommend? The orange MC Bazel ODV-GBS-C seems to be a good option for €85 on Amazon.
If you don’t have a GBS-Control any version I think will do. Mine was a plain brand from AliExpress.
But there’s also another potentially neater solution. Component to VGA transcoder. It’s a neat little adapter box. Depends if you need the extra GBS-C things.
(Component connections on TV is a processed signal, so no surprise you were disappointed. Only Analogue VGA is unprocessed)
Whats about a direct link from the Component Cable of the Wii to this > DVI-I Male to HDTV [RGB] Component Adapter > to DVI-I Input of the 4121?
I find the additional GBS-C features interesting. I would also like to upscale some N64 content to 480p or 1080p. However, this inexpensive YUV to RGBS solution would also be suitable.
What do you think of this Converter? Component to RGB Converter from Converters TV
It’s a long time ago but I think I tried one of the adapters in your photo and whilst it got a picture either the colours or sync were wrong. So sadly a little more electronics is needed.
I’m not sure about the one you linked. Will look into it
The one from converters.tv has following options.
Output:
PC RGB HD progressive input, or 15K video RGB for SD interlaced input
Most PC monitors accept multi-sync input therefore can lock onto signal timing of the CP-265s RGB output. In the rare case, no picture shows, try a different resolution on your HDTV device or monitor.
I dont know if the 4121 can handle it.
I don’t think I’ve ever personally run anything that low KHz on mine. Maybe @Gravitone has or has some insight?
There will be no processing when you input 480p directly over dvi with a hdmi-dvi cable. Assuming its 640x480. wider resolutions will be scaled down to fit the panel. I have not tried a 15khz vga signal over the dvi-i analog pathway, but I can try that out sometime.
I used one of those adapters with my ps2 and it worked just fine. Both 480i and 480p modes work.
The Wii’s video output quality is notoriously poor anyways compared to other systems, for the cleanest output you’d have to install one of those internal mods based on the gcvideo design. It will give you direct digital 480p output over hdmi, removing any analog video stage from the chain, and then just hook it up with a hdmi to dvi cable. I want to try this with the hdmi mods for gc,wii,and original xbox thats avialble now, but have yet to buy, install, test any of them.
That means the first option would work just fine for a pixel-perfect picture with the Wii on the 4121?
Do you talk about the Component to RGB Converter from converters.tv?
This is interesting because this has not worked for me. Is it supported by what we know about the electronics of the TV from the service manual?
Can you give details of adapters and cables used and the mode the TV is in? Photos would also be cool. I’m travelling right now otherwise I’d try it myself.
