Samsung - Odyssey QD-OLED G9 (G91SD)

Yes, I have it. Just bought it like few weeks ago. Work great with no issue. You can get the monitor for cheap at Costco for $600 thou

yup G91SD, 5120x1440 resolution OLED 144hz

(I fixed up my formatting and language with ChatGPT, as I was a bit scatterbrained in my original write up, but this was written by me and reflects my own experience.) \----- **TL;DR:** *In my opinion, if you can spend $2,000 and do not specifically need a super ultrawide or glossy display, the LG OLED (with its noticeably higher resolution and extra vertical space) delivers a significantly better overall experience.* \----- This is specifically for the biggest OLED options right now. I bought the Samsung, used it for a bit, and ultimately returned it for the LG. I use my monitor for both gaming and work. There are many excellent comparison and reviews already, but I found they were so heavy on technical specs, and due to the unclear relative scale in a video to real life, it made it difficult to get a sense of how the monitors actually feel in daily use. This post is meant to be a high-level, practical explanation of why I strongly prefer the LG by a wide mile. I hope it helps others doing research. As well for people who don't have a distinct and necessary prefance to super ultrawide and/or glossy. **Monitors Compared:** • **Samsung 49" Odyssey OLED G9 (G91SD):** 5120x1440, 144Hz, glossy, curved • **LG 45GX950A-B (45" OLED Ultragear):** 5120x2160, 165Hz (330Hz in 1080p mode), matte, curved Both were purchased from Amazon. Returning the G9 was straightforward. The large box was a bit awkward to repackage. But I got it to UPS and got an immediate return accepted notice once scanned in. As well, I selected an older G9 model specifically to avoid Samsung's "smart" features. From my research there was no difference in the actual screen technology. And as I describe later, the only real benefit the Samsung had for me was price. Everything shared here is just based on my personal experience and opinion and is not objective. # 1. Price After taxes and shipping, the Samsung cost around $900 and the LG was approximately $2,000. In my opinion, the LG is well worth the extra cost. It is such a high-end and gorgeous display that I do not expect a comparable option at a lower price anytime soon. If I could not get the LG, I would personally prefer using two 1440p OLED monitors angled toward each other as a second-best setup over the Samsung as well. That said, if you want everything on one large screen or prefer super ultrawide display more than anything, the Samsung offers excellent value. It provides a beautiful image and generous screen space at a great price. If the LG is beyond your budget, you should not feel like you are missing out. The Samsung is still a very good experience, and the difference is not so extreme as to justify making yourself financially anxious. # 2. Dimensions and Aspect Ratio This was the biggest reason I made the switch. While the G9 looks amazing, the low verticality to keep a 32:9 aspect ratio within a reasonable size (and within the 1440p resolution) is not ideal for most everyday content. The vast majority of websites, games, videos, and images are designed for 16:9. Trying to force that into a 32:9 panel (with the verticality of an average 16:9 screen) felt claustrophobic to me. Unless you truly need a super ultrawide format or only interact with super ultrawide content, I believe most users will likely find the Samsung uncomfortable. Content often ends up small when centered or pushed far to the sides, which is not enjoyable on such a wide screen. The LG handles this much better. It works beautifully as one large 16:9 screen or can be split cleanly into two side-by-side windows. And anything that is 21:9 content looks stunning. Even standard 16:9 content appears great thanks to the OLED black levels that blend the letterboxing into the bezel. The LG delivers a widescreen effect that feels useful and natural to me. # 3. Resolution This was the second major reason I returned the Samsung. Both monitors have a horizontal resolution of 5120 pixels, but the Samsung has only 1440 vertical pixels. For a screen that large, that resolution is not sufficient. It causes text and images to feel stretched and less sharp. The LG, with its 2160 vertical pixels, looks incredibly crisp. Some users have mentioned text fuzziness, but I have only noticed that with applications that do not scale properly. I'm writing this on the monitor and it looks perfect. If needed, you can adjust the screen to act like a virtual 4K display. Anything running at native 5120x2160 looks better than anything I have used before. The only downside is that it is so sharp and you're so close up to it, it reveals compression artifacts and lower texture quality in games or videos that you might otherwise overlook. # 4. Bezels The bezels on the LG are noticeably thinner than on the Samsung I used. This creates a more immersive experience and reduces wasted screen space. # 5. Matte vs Glossy The G9 wins here as glossy screens can look more vibrant and provide more visual punch. That said, I adjusted to the matte finish on the LG very quickly and now prefer it practically. And it's higher resolution has a bigger impact on visuals than screen type. Reflections are minimal on matte. My desk is near a window, and the Samsung often acted almost like a mirror during daylight. The LG avoids that issue entirely. In my opinion, it also appears brighter in typical lighting conditions. # 6. OLED Quality After adjusting settings, both monitors looked beautiful. I am not particularly sensitive to subtle color shifts, so I cannot speak to any differences in white balance or tint. What I can say is that both offer rich colors and deep inky blacks. When displaying a fully black screen, both monitors appear completely powered off. # 7. Physical Size This is different from resolution or dimensions. In many video reviews, the LG appears much smaller horizontally than the Samsung. However, in person the difference is far less dramatic. The LG still feels absolutely massive when in front of it. You would need to place the monitors side by side to truly notice the difference in width. Even though the Samsung is technically wider, the LG still delivers an almost super-ultrawide feel in actual use while not sacrifing verticality. # 8. Plug and Play This may not apply to everyone, but in my case the LG was significantly easier to set up with Windows. It immediately detected the correct resolution and refresh rate. The Samsung required more configuration to get everything displaying properly. It just felt a bit more fussy overall. # 9. FPS and Performance The LG supports up to 330Hz in 1080p mode, which is incredibly smooth. However, the drop in resolution is definitely noticeable on a screen this big. I prefer to use the monitor at its full 5120x2160 resolution at 165Hz, which still looks and feels fantastic. The high refresh rate is a bonus, and switching between modes can be done with one button. \-------------------------------------------------------------------------------------------------------------- Let me know if you have any questions!

The Samsung? I didn't like it for gaming either. I actually thought it was better for work than gaming tbh. Super ultrawide is really cool for games but very limited in application

hey it’s been ages but have you gone through and gotten the monitor?? as i have the same monitor and thinking about upgrading my gpu to the 7800 xt but don’t know how will it perform, could you please share with me any info on how it runs different games at what graphics settings?? That would be much appreciated as i can’t find any benchmarks on that resolution for the 7800 xt, Thankk youu!!

I would suggest go with Samsung Odessey G9 Neo 49 inch. You will find it cheap also I have a Macbook pro M1 pro laptop and for coding and office work it is perfect. Issue with OLED is burn in problem, almost all the time I have VS Code open so wouldn't like that. And due to subpixel arrangement, OLEDs are far less idle for using Office work, your Text might look pixelated. My G9 works perfectly at 60 hz not sure what is the issue but I cannot find 120hz. Its an Macbook issue, my other windows laptop works perfectly with 120 hz. Dont know why Apple restricts external display even though CPUs are powerful.

Its good for office work/coding. I use it all the time. Text is crispy. Although if you are a UI developer I will not recommend because of the local dimming. It darkens the small white color in black background. So sometimes it pretty hard to see my mouse in dark background. But I am super happy for my Work. I can open my instances, 2 VS code window side by side without any issue.

I love both my 49" Samsung Odyssey monitors. Have the OLED 144hz and the older white back one with 240hz. Can't see myself going back to 34" let alone 24". Not every game supports the 32:9 aspect ratio which sucks but man when they do. Not sure why they aren't on any top picks list but for the record if any of mine were to break l would replace them with the same model in another in a heartbeat.

Thanks for the review—really appreciate it. I was a bit worried about how the matte coating would feel coming from the Samsung G9 QD-OLED, since I’m used to that glossy punch. I think I’ll probably hold off for now and wait until someone brings out a QD-OLED 5K2K.

I was going back and forth between both as well, but I’m leaning toward the 5K2K. I’ve got the Samsung G9 OLED right now and honestly I’m just so over the 32:9 form factor. That said, I’ve been holding off because CES is around the corner and I’m really hoping we see a new model with tandem tech and 240Hz. Just not sure if I should wait or pull the trigger now.

Samsung QD-OLED G9 is quite stunning, since they're glossy like the Macbook's they pop really well in color. Otherwise you don't have many options except for MiniLED backlights in the Neo G9 49"and the G9 57", with the G9 57" being the main attraction due to its size and resolution (Dual UHD). Unfortunately those are VA panels, but they're still very good compared to a few years ago. There's no MiniLED IPS 32:9's unfortunately like on the Macbook. Only OLED, VA, VA + MiniLED, IPS, IPS Black.

Work/Productivity and value only? Probably yes. OLED is out of question, so you're stuck with VA or IPS. Unless you need Samsung most of the 32:9 VA panels are the same 144hz/240hz panel Samsung uses - you might find a cheaper 32:9 VA from ASUS, Acer, Phillips, Illyama, AOC - most use the exact same panel, some OC it out of box or offer other stuff that could actually be interesting for work/productivity (like a built in kvm, usb-c power delivery, speakers, etc.). LG does 32:9 IPS panels, better color and viewing angles on those make it interesting for productivity/work too, depending on the type of work. So I would keep those in mind and check the pricing in your country. Maybe there's a better option, otherwise the entry level G9 is totally fine for work.

49” is the Samsung SD series and the 27” is the Joled LG ep950.

It’s the g9, I’ve seen the display. The Samsung is qd oled (pyramid subpixel layout) where the 5k2k is woled (vertical rectangular subpixel layout RGWB) my Alienware is qd oled from Samsung and I can say the lg side by side doesn’t look better than Samsung. It’s just got a better resolution. But if it’s down to resolution, 3840x1600 was my sweet spot

I found if you have the non-glare model near a window(other lights) it is extremely distracting if you are playing an FPS or something that requires that level of attention to detail/response time. In a dark room it's a phenomenal screen. Unfortunately for me I like my big bright windows uncovered and this screen couldn't deal with the ambient light.
