The MSI 342C has okay HDR brightness. While it doesn’t get as bright with real content as the Samsung Odyssey OLED G8/G85SB S34BG85 or the Dell Alienware AW3423DW, it still gets very bright with small highlights, and they pop against the rest of the image. The EOTF doesn’t follow the target well either, as dark scenes are too dark, and other scenes are too bright. There’s a sharp cut-off at the peak brightness, meaning it gets the brightest it can before your PC does any tone mapping.
These results are in the ‘Peak 1000 nits’ DisplayHDR mode, which lets it get bright, but it has an aggressive ABL. This can be noticeable when you’re on the desktop, as you’ll see some changes in brightness when opening and closing windows. If that bothers you, you can also use the ‘True Black 400’ DisplayHDR mode, for which you can see the results below. It doesn’t get as bright, but the EOTF is also much better, following the target almost perfectly.
