Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The 49-Inch Odyssey G9 delivers excellent HDR with DisplayHDR 1000 certification and an effective local-dimming edge backlight. We recorded some extremely impressive numbers in our tests.

At over 1,300 nits, the G9, again, takes things to another level in our HDR contrast tests. We measured these results using full-field patterns, which means the 100% pattern was bright enough to be seen from space -- seriously though, we couldn’t look directly at the screen.

Black levels proved difficult to measure because the backlight is completely shut off when the brightness signal is 0%. By turning on a small block of info text from the pattern generator, we were just able to pull a 0.0225-nit measurement. That makes the HDR contrast ratio an impressive 58,881.7:1. And this can be seen in actual content. The G9 is a standout among HDR monitors.

The G9’s HDR grayscale and color accuracy are equally fine. We could see slight green errors in the grayscale test, but they weren’t visible in actual content. Only the brightest highlights had the error, and they were too small to show a problem. The variable backlight causes an interesting wiggle in the chart after the 75% transition point, but luminance tracks perfectly up to that level. And you won’t see a problem in content because levels over 75% are only in the smallest highlight areas of the picture.

HDR color tracks almost perfectly, better than most of the HDR monitors we’ve tested. Every measurement is on or close to its target. Yellow is slightly off hue but not visibly so. Primary colors are right on the money, making HDR images more natural and lifelike. It doesn’t get much better than this.

    I was hoping this would be about the supposed 2021 mini-led refresh for the G9, since the original model covered here is a year old by now. It could fix my main gripe with the G9 which is the awfully subpar 10-zone local dimming.

    Any news on the 2021 model would be appreciated.

    I just love mine. It is really a great experience, it sets PC gaming apart. Regardless of the screen size and format, fast, great color, acceptable contrast. Mini LED local dimming would be great IF they are fast enough for gaming.

    Shouldn't affect the panel frequency since it's just a backlight change. Besides, it should be faster than the current dimming tech. There's a supposed leak on the updated version that pretty much keeps all the other specs, but flaunts a VESA DisplayHDR 2000 certification (doesn't even exist yet). Same resolution, response times and support for G-Sync and AMD FreeSync Pro, so no changes there.

    I had the previous version of this monitor (the 49" Samsung CRG9). I'd add one "Con" to the list for the G9, which is that the aspect ratio does NOT play well with some games. If stick to the big AAA titles, you'd probably be fine, but if you like to mess around with some indie games, or more niche games, you'll have trouble. Of course you can force it into some terrible 16:9 resolution and have half the monitor be black bars... but that kinda ruins the point doesn't it? I gave the 49" to my 15 yr old son, and got the Samsung G7 32" 16:9 works with everything :) Oddly, I don't miss widescreen AT ALL.

    2x27 Monitors are also out of eye vision field. you wont see the edges of the game and the center at the same time

    I've seen this thing in person and it's a behemoth. I would love to get one, but a bit out of my price range. I think it would be awesome for Flight Simulator!

    I have thought about buying a VR headset at one point, that is definitely something on my list.
