AutoActions VS Playnite

I've just discovered https://github.com/Codectory/AutoActions which detects when a user-defined process starts and can toggle HDR on, then back off again when it exits. I've gone through the list at https://www.pcgamingwiki.com/wiki/List_of_games_that_support_high_dynamic_range_display_(HDR)) to add entries for all the HDR-capable titles that I have installed.

For anyone with any of the myriad of HDR monitors that prefers to leave desktop mode in SDR RGB, I just discovered that the excellent Playnite game launcher has a feature where you can enable HDR on a per-game basis. Simply tick the "Enable HDR support" option under "Advanced" tab for the settings of the games that you want HDR turned on for. I was previously using the now-abandoned AutoActions for this, so glad to see there's an alternative in a tool I already use.

This is what I've been using, although I don't have an ultrawide monitor. I mainly use it to change it from 1440p to 1080p https://github.com/Codectory/AutoActions

You can use third party programs like https://github.com/Codectory/AutoActions which can automatically enable HDR first when you launch a game and automatically disable HDR when you close the game.

If your gpu supports HDMI 2.1 it will be better for bandwidth. As for HDR, while windows is getting better its still not great for desktop usage IMO. I like to use this tool here: https://github.com/Codectory/AutoActions/releases/tag/1.9.19.

There's an app called AutoActions which will allow you to automatically enable HDR on a per app basis which works really well for me. Unfortunately the author is no longer maintaining it, so hopefully nothing breaks!

I've done something similar before with Playnite (an open-source PC game library manager), which has an HLTB plugin.

Playnite: The one with the most features and libraries available via addons and has a lot of options for customization. In my opinion the best one available for this purpose.

Here's a project for Playnite 11: https://github.com/JosefNemec/Playnite/milestone/9

As for my LGO, the only other app I've installed outside of the standard launcher was Playnite to consolidate all games into one place as Legion Space doesn't detect everything I have installed and I don't want to manage manually adding games to their launcher.

use playnite instead of the individual launchers.

Here is where I come in and recommend everyone check out Playnite: https://playnite.link/

When I care about supporting a developer or publisher and they offer their product on their own storefront DRM-free, I will often go there to buy. Or I buy from GoG which takes a smaller cut. Playnite lets me launch my Steam and non-Steam games in a seamless fashion. Steam still does a great job as a game installer/patch manager, and helps me discover new games. But I'm not locked into paying them a 30% fee, which is pretty brutal for some smaller publishers.

Not exactly what you are looking for, but I've been using Playnite to launch everything on my computer for years.
