Features 5

  • 39-Inch QHD Workspace: The 2560x1440 resolution and 16:9 format give racing sims, fast games, editing timelines, data dashboards, and multi-window entertainment room to stay visible on one screen. The layout reduces constant window switching and suits home desks, office workstations, studios, or entertainment setups that benefit from a larger working area.
  • 165Hz Motion with 1ms MPRT: The refresh rate makes scrolling, cursor movement, video, and fast on-screen action feel smoother, while 1ms MPRT supports clearer motion. Adaptive-Sync can help reduce visible tearing with compatible hardware. Maximum refresh performance depends on the source device, input, cable, and system settings.
  • 3000R Curved VA Image Quality: 3000:1 contrast and 99% sRGB / 88% DCI-P3 coverage support clear text, deep dark tones, vivid media, photo review, presentations, and creative work. The image profile is suited to mixed daily use where both readable detail and visual depth matter.
  • Multi-Device Workflow: USB-C 65W supports compatible laptop connection and power delivery; PIP/PBP can show two compatible sources on one screen. The combination is useful for hybrid work, content production, analysis, streaming, and users who switch between personal and work systems.

Really good for an unknown brand monitor
Size: 39 Inch-165
After using this monitor a few years I can say I am still happy with it. Since then I actually believe this is a rebranded monitor made by the same manufacturer that makes all the other rebranded monitors. You know who i mean. Not a bad thing really. The color quality is still good, no dead pixels yet, I didn't know when I bought it that it has speakers! Not like studio grade monitor speakers but they aren't bad at all. Good enough for me to take a break from tracking to play a racing game on the PS5. The controls are a little clunky for accessing the monitor settings and quite a few brands are using the single button maneuver right now. Hopefully this too will pass. I like the red light on the back that reflects off the wall for ambience and the stand is sturdy with a reasonable footprint. The curved screen feature is nice. I wish all my monitors were curved but it's not a priority at this time. For the price paid, I think it is an incredible value with decent color quality compared to the other two monitors I also use. ... show more

"Hidden Gem" -- Larger and Less Expensive then Competition
Size: 39 Inch-165
This item is larger and less expensive than it's competitors. I was in the market for a large monitor and was impressed when I found this one. There is a Samsung and an LG out there that is I think 34" each. They have the same aspect ratio, but they are both more expensive. This one has fewer connections, but I just needed one port, and this has that. In fact, this has one of each (HDMI, USB, and DVI) and a cable for each. Also, the refresh rate is fine for me as well as the picture quality and adjustment range. Overall, I think it's a great bargain given what else is out there. Kudos to DG. ... show more

Excellent value & performance
Size: 39 Inch-165
A little tricky to hook up but once you get it done this monitor is outstanding. I use it primarily for office work. it makes the bookkeeping so much easier because I can put bank statements along side the spreadsheet for easier viewing. Larger size is easier on eyes & the neck. Crisp true colors for photos, good contrast. ... show more

Connection Issues After Only Two Days
Size: 40 Inch-120
Price is good and it’s lightweight. Unfortunately, that’s about all I liked about it. The colors feel off to me and I’m not impressed with the overall picture quality. More importantly, I’ve been having connection issues since day one. The picture keeps flickering and randomly cutting in and out during use. Sometimes the image disappears completely for a few seconds and then comes back. I’m using a brand new top-spec Mac that works perfectly with all my other devices, so the issue is clearly not coming from my setup. This is only my second day using it and I already don’t trust the reliability. I don’t want to waste time dealing with troubleshooting or warranty claims on a brand new product, so unfortunately I’ll be returning it. ... show more

It's not bad, if you understand what you're getting. [Returned due to fault]
Size: 39 Inch-165
I purchased this to use as a new primary monitor on my sim rig for gaming. It's... Alright. The size is great, it's much bigger than a traditional monitor, a bit smaller than most higher res TVs you'll find, it sort of sits in the middle ground of the two. For a size comparison, it's just a bit wider than a 34" ultrawide, and almost twice as tall. The image isn't *too* bad (more on this later), colors are ok once you adjust the screen. The size makes games truly immersive. My screen sits less than an arm's length from my seated position, so larger screens like this just fill your field of view and you really get brought into the game. It's *fast*. I didn't think 165hz would be that big of a difference from the 144hz I'm used to, but this thing just feels much more snappy in everything. This being a VA panel, it does have some of the inherent ghosting that comes with that. The "VA smear" as it's known. It isn't as bad as my other VA monitor, but definitely still present. Like all VA screens, it's better or worse depending on what is being displayed. Some games show it worse than others, scenes with higher contrast or brighter colors will show it more. This is just a VA thing, and companies trying to clock them higher than the tech can really handle and still retain a clear image. The major downside of this monitor comes down to what it is. 1440p at this size just isn't very good. That's a lot of screen, and relatively few pixels to fill it, so you end up with a pretty low pixel density. Meaning, you don't get the clearest image in the world. The pixel pitch is fine, there isn't any screen door effect going on, it's just not a clean image. At a normal 100% scale, text is difficult to read due to becoming pixelated. When I first hooked this guy up and powered it on, I was disappointed. I knew what I was getting into, I knew that this resolution at this size would have some image quality issues, I just didn't think it would be quite so bad. Coming from 1440p 34" ultrawide, this was a huge downgrade in quality. A screen this size really should be 4k. I stuck with it though, and after a few days, it didn't seem so bad anymore. My eyes and brain had adjusted to it, and it was alright. Text still looked pretty bad, but overall I was mostly happy with the monitor. I was still sort of on the fence, but it suited my particular needs. And then it started having issues. After only a few days of use, it started flickering random horizontal bars across the screen. They happened so fast that at first I thought I was imagining it, but after paying very close attention, it was definitely there. It was always at a different location, and different size, a white bar that flickered for probably one frame. I did the usual, checked my GPU, cables, tried new cables, tried different ports. The result was always the same, the monitor was flickering. Luckily I kept the box. ... show more

Great monitor! A+++
Size: 39 Inch-165
My first gaming monitor and the colors and detail are amazing. FPS using an AMD Ryzen 9 5900xt 16 core with a AMD Sapphire RT 9060 XT 16GB video card was fire today. Great looking monitor. I was using a 40" TV and prefer the taller screen than a 34" ultra wide. Worth the money to me as I do so much on PC. ... show more

Great for the price!
Size: 39 Inch-165
The monitor was bigger than I expected (which isn't a negative!), and appears to be in good shape. There are always better options out there, and I would've loved a 4k monitor in this size and refresh rate, but not for more than double the cost. For what you are paying for, this monitor really is quite nice, I was a little skeptical considering I haven't heard of the brand, but, it works and looks great. I also appreciate that this monitor has more ports than other manufacturers and the monitor itself and stand are very sturdy. I confirmed the refresh rate at 165 Hz and the resolution, I am always worried with the non-mainstream brands that the product isn't as advertised but this was not the case. The monitor also came with the proper cables which was a plus. If you are looking for a sub $500 gaming monitor, this is it and the screen size is great, I hate small screens. For the cost, it's a 5/5, only downside is, the built in speakers kind of suck, so aftermarket speakers are required, but, I was kind of expecting that. ... show more

Big and great value, but...
Size: 39 Inch-165
This was one of the only choices for a 39" monitor at a cheaper price. It's a great monitor, but... Cons: -Slight uneven color and brightness in parts of the screen -Too reflective and doesn't have a matte finish -No height adjustment, only Tilt Pros: -Great Value for the size -Colors are vivid and accurate (with some slight adjustments) -Very bright Overall a great monitor, but my biggest complaint is the uneven lines/areas in the screen where the brightness and color is a little off. And I understand, this is a budget monitor, so I got what I paid for. That is my old 32" monitor next to the new 39" for reference ... show more
