Samsung 57" Odyssey Neo G9 Series Dual 4K UHD 1000R Curved Gaming Monitor, 240Hz, 1ms with DisplayPort 2.1, Quantum Mini-LED, DisplayHDR 1000, AMD FreeSync Premium Pro, LS57CG952NNXZA

I've had this monitor for around 7 months and it's exceeded already high expectations. it's great as a full monitor, which is what i did for the first several months. assuming you have the gpu power for it. then i started using it as 2 monitors. one resolution is 2560x3260 which is perfect for my secondary screen. the main is 5120x2160. also perfect size because it limits frame loss due to the full res. though the full res is beautiful and game changing. it's more than a lot of games need. having both options at the flip of a switch is fantastic. which brings me to branching out to having consoles on the main and my pc on the secondary. if i turn on the console the monitor pops up with a notice if i want to switch to the other input. underrated and unexpected plus. you can even choose which audio source you want to listen to of the 2 (or more) on screen. i believe you can use up to 3 but i haven't tested that yet. also note only one DP slot. i had problems initially with using a dp only.

**purchased for $1900 with my own money** (maybe a double flash sale, $2000 on sale for December, additional $100 off for a few hours one day)So I've used this monitor for about a week, 12-16 hours a day (work during the day and online MBA school at night). Here are my initial thoughts.1. HDMI was very buggy. When the monitor went to sleep, it would try a few times to wake up. Then, it eventually crashed (rebooted) my M2 Ultra Mac Studio (a great machine).Switching to a DisplayPort from the USB-C port (back of Mac) has been flawless. (I was hoping to get that port back by using the HDMI, but my previous setup took two USB-C ports, so it's still a net win of one port for me.The screen itself is bright and clear (what you would expect) no dead pixels, artifacts, or flaws of any kind. For work and school, 120Hz is more than good enough, as I didn't see a difference when I switched to 240hz.2. The curve works great about two feet from my face. Since it's on a desk against the wall, it goes out a little further than the previous setup, it was doable, and I got back some desk space undernead having one base instead of two previously. The "wrap" around my field of view is definitely worth the extra space but see the next point.3. The rear lighting and futuristic design were useless since they were against the wall. There's some extra bulk back there that could have been saved (and money) and made the profile slimmer had they not built all that.4. I don't play games much, but Angry Birds was great. Getting the whole screen to show the entire landscape without having to scroll around horizontally was nice. Any side-scrolling games would benefit, assuming they programmed the game to use the extra space.5. I would have liked them to integrate booming loudspeakers (like the other Samsung gaming monitors) so I don't have to use external speakers.6. Also, for this price range, I would have liked to have a high-quality built-in 4K WebCam (even snap-on in the back, but still included) and mic for Zoom calls as well so I can work with two fewer peripherals on the desk.7. Using the Mac Spaces feature, I can have three windows per space and one space per activity (work, school, reading, file management, photos, etc. It's a game-changer, for sure. All without a fat bezel in between the middle of the screen. (If Mac fixed the full-screen function to allow for three full-screen apps instead of two, that would be even better) Multi-page docs or wide spreadsheets are a huge benefactor of this super wide screen.Overall, this was a great purchase for me. I last bought monitors when the Dell 4K ultrashare UP3216Q came out (8 years ago, and they still work great, BTW) and spent $2000 each, so paying $1900 for this monitor was a great deal.

RE: SAMSUNG 57" Odyssey Neo G9 Series Dual 4K UHD 1000R Curved Gaming Monitor, 240Hz,After a lengthy discussion with Samsung Support, it appears that a maximum refresh rate of 120Hz is the best that can be had at full resolution with the HDMI 2.1 port on an RTX 4090. While there are graphics cards with DP2.1 ports that can run at the higher refresh rate (e.g., RX 7900 XTX), the reality is that they do not provide any where near the graphics performance of the 4090 (i.e. RX 7900 XTX has lower net frame rates in actual game play at max res) so not a solution.Samsung support could not provide a means to use two cables to simulate a two monitor circumstance on a single monitor display using PBP that would match the existing (and limited) single cable performance. In fact, in PBP mode the monitor is overall slower than 120Hz. I currently run my games on a 32" monitor at over 120Hz (many run up to 240Hz) so this monitor is a step down in that regard (at a huge step up in price).At this point, it is better/cheaper to have two monitors. In particular it is cheaper to use two SAMSUNG 32" Odyssey Neo G8 4K UHD 240Hz monitors each with 3840 x 2160 Pixels for a total of 7680 x 2160 Pixels. You can run each of these at up to 240Hz simultaneously on a graphics card such as an RTX 4090. I would rather have a narrow bezel separating two monitors of equivalent resolution than the diminished frame rate on offer here.Consequently unless/until Samsung recognizes the reality of the Graphics landscape and (assuming possible) changes this monitor to operate as two independent bezel-less monitors each on a distinct cable, I can not recommend it. Since I am not willing to give up the higher refresh rate of the 32" monitor, I returned this monitor.EDIT: This monitor also has the persistence problem afflicting many Neo monitors concerning the use of HDMI 2.1. What happens is that the UEFI/BIOS screen will not display if HDMI 2.1 is displayed most cases. Often times when booting with HDMI 2.1 enabled, the OS can bring the display up, but not always. This does not happen with any other monitor. It is not corrected with the the latest firmware updates either. I had to show Samsung support this behavior on a live video stream before the support agents accepted the reality.The only evident work around is to shutdown the PC, then press the OSD joystick so that the OSD menu is displayed on the screen and then power-up/boot the PC. In this circumstance, the UEFI/BIOS screeen will display and the PC will boot with the display operational. To use best use this work-around, it helps to increase the OSD on-time in the OSD menu to the maximum time so that there will be enough time for the PC to boot. I guess that Samsung didn't test for this or chooses to ignore the issue. This is unacceptable behavior for a monitor in this price range.
