Software, shader-based BFI+VRR should be essentially automatic, since the shaders are naturally tied to the content refresh rate in VRR. Driver-based BFI (that is, the options in the menu), I’m not sure about. EDIT: just asked around and it does not work with VRR

Which offers more reliable/smooth bfi? Driver or shader? Rolling scan simulation sounds amazing, but i doubt my 120hz tv will do it justice.

It must be that burn in isnt down to heat as such just how intense the light gets or theres some exponential in there somewhere between power input and light emitted that I dont understand.

It could be part heat, part voltage, maybe even some sort of capacitance taking place. So that’s why heatsink help but don’t eliminate the issue completely.

I suppose it would be more accurate to say that LG’s hardware BFI is fundamentally incompatible with their HDR tonemapping in a way that results in radically reduced brightness.

Is it that the only reason why LG and other manufacturers turn off HDR with BFI purely because BFI lowers the peak brightness too much and manufacturers dont want to confuse consumers? I dont think technically there is anything stopping them from having BFI and HDR turned on at the same time? Possibly some ‘mechanical’ property of the display stops them?

[Wilch]

You can use HDR with BFI, at least on my C2. I’d say HDR is essential with BFI to make up for the brightness loss. LG don’t allow BFI and VRR together.

I tested software bfi and it’s still pretty ropey compared to hardware. It does work with g-sync, but not smoothly. I’ll stick to hardware bfi without vrr. One thing both hardware and software bfi seem to hate is non-50/60 hz games such as 54hz arcade games

CyberLab Death To Pixels Shader Preset Packs

CyberLab Megatron NX Death To Pixels 4K HDR Shader Preset Pack!

[Nesguy]

What’s the best way to play 480i stuff with Megatron?

I’ve been removing the scanlines from Megatron by setting the scanline min/max to 2.00. However, this makes the image way too bright. What’s the best way to deal with that?

Has anyone had any luck decoupling the interlacing stuff from guest’s shader?

Funnily enough, just about an hour ago, I was contemplating this exact scenario.

@Nesguy

Maybe you can try 1.60 instead of 2.00?

@Nesguy

Has anyone had any luck decoupling the interlacing stuff from guest’s shader?

You know you can use RetroArch’s built-in HDR implementation with any shader? You can start with whatever Peak and Paper White Luminance values you already use in your Sony Megatron presets for your display then just hack away at recalibrating Saturation, BrighBoost, Post Brightness and Gamma_C using your shader of choice.

I’ve gotten some pretty decent preliminary results out of a couple of my Mega Bezel presets but what you’ve asked about should probably be the next logical step.

Maybe the better approach might be to decouple the SDR to Tonemapping implementation of Sony Megatron Color Video Monitor (which might probably be redundant given that it’s already built into RetroArch)?

[Nesguy]

I think there may be an issue with the tonemapping in general. I’m playing around with it sans shaders and I cannot get it to not clip the highs. I’m using the SH2 map screen to test.

raw PCSX2

In RA, all the whites/greys get clipped and it’s just the same eye-searing white across the entire image. I haven’t been able to fix it via any combination of settings in the HDR menu but maybe I’ve missed something.

edit: probably worth mentioning that I’m running PCSX2 standalone and using the WindowCast core

2nd edit: disabling HDR via the RA menu doesn’t even fix the clipping, so now I’m leaning toward this being a WindowCast issue

[Cyber]

@Nesguy

PCSX2 standalone

If you’re running PCSX2 Standalone then you could probably try the ReShade port of Sony Megatron Color Video Monitor or Windows’ AutoHDR.

[Nesguy]

I’m having a lot of problems with HDR in general, not specific to Megatron but each implementation seems to have it’s own issues.

Without shaders, the default HDR settings cause clipping and black crush. If I make the following adjustments, it solves it:

Peak Luminance 1000 Paper White 350 Contrast 5.6x

However, with Megatron loaded no amount of adjusting these settings in either the HDR settings menu or the shader settings solves the black crush or clipping.

And WindowCast seems to have it’s own issues, too. There’s a ton of clipping with all shaders disabled and no adjustments in the HDR menu solves it.

With guest, the default settings in RA are pretty good but I have to raise contrast to 5.8x to pass the PLUGE. So it’s kinda just all over the place and I’ve resorted to creating multiple config files for now

[Nesguy]

Just wanted to report that the scanline moire problem with the low TVL slot mask isn’t present (or not visible to the human eye) in guest-advanced when using the default scanline settings, types 0-2.

Some additional scanline options might be useful in Megatron (or maybe it’s possible to achieve the same results using the existing settings and I haven’t tried hard enough)

[Cyber]

@Nesguy

Interesting observation.

Is this with Azurfel’s build or the current official Sony Megatron Color Video Monitor build?

I’ve noticed white clipping once Paperwhite Luminance is set too high relative to my display’s actual capabilities. I never tried it without any shaders loaded though.

@Nesguy

Some additional scanline options might be useful in Megatron (or maybe it’s possible to achieve the same results using the existing settings and I haven’t tried hard enough)

Not opposing you in the least but after quite a lot of tinkering and time, I’ve began to realize how powerful and flexible Sony Megatron’s scanline shaping controls are. You can probably get almost any look or shape you like but the controls are more analogous to analog knobs vs the button presets that CRT-Guest-Advanced uses in addition to its own analog style scanline shaping controls.

@Nesguy

(or maybe it’s possible to achieve the same results using the existing settings and I haven’t tried hard enough)

I vote for the latter. You may not achieve verbatim 1:1 results but you should be able to get something that’s at least comparable.

With my new Megatron NX preset pack I’m amazed at some of the details and beauty in rendering I’m seeing in the same games I’ve been playing so I think it’s just a matter of commitment and learning curve. You also have to try letting go of some of the entrenched ways and approach to doing things and you’ll only enjoy and appreciate the shader even more.

With regards to your calibration issues, if you hold on a bit, I can put together and share a preset that includes the latest decoupled CRT-Guest-Advanced-NTSC NTSC Section + Horizontal Filtering Section with the latest Grade + Sony Megatron Color Video Monitor.

Also, @HunterK recently posted some modifications of the Megatron Shader which includes some modulation noise, which can help immensely with moire issues.

I haven’t tried that nor Azurfel’s build yet as I’m really happy with what I’m seeing with the original build so far.

Here’s Hunterk’s modification:

Sony Megatron Colour Video Monitor

I tried adding in some really slight tex_coord noise and I like the result. On all of my CRTs, if I get super-close to them, there’s some subtle movement in the scanlines and it looks pretty much like this (just a couple of lines added to the base megatron shader file): https://pastebin.com/Xvd3CL7r I’m not going to bother with a screenshot because it wouldn’t really show anything.

[Nesguy]

@Cyber

This is with the latest official, just updated assets to make sure.

Yep I probably just need to work at it some more.

[Nesguy]

Is there any way to automate the updating/installing of these preset packs? Can they be added to the repo and updated via the online updater?

[Cyber]

I guess that might partly depend on if there’s enough demand for stuff like that. Then there’s the whole issue of maintenance.

It is something to think about though.

[Nesguy]

Can you add your presets to the “presets” shader directory in RA? You’d have to update and submit a pull request every time guest updated, and… yeah. I don’t know if that’s actually easier for anyone
