IMAGE QUALITY
The top model projector that i have here is the Horizon Pro 4K by XGIMI (review soon) and so this is what i used to test the S ALR Obsidian floor rising screen by VIVIDSTORM (along with the HD Dune Max Vision 4K).
I am by no means an expert on projection/projector screens (the VIVIDSTORM S ALR Obsidian is the actually the 6th I’ve used to date and the 2nd most expensive out of those) but image quality is easily a 9/10 and that's compared to a fixed screen worth almost 5 times as much. Now pictures for good or bad don't capture the full image quality due to the very low light conditions but i think it's easy to see just how well the S ALR Obsidian does, even with dark scenes. That being said you can have the best projection screen out there but unless you pair it with an equally good projector nothing will come of it and yes, the XGIMI Horizon Pro 4K is a very good model (short clip should be up by now both in TikTok and YouTube - quality however is not great).
