I second this monitor. I've had many similar Dell monitors over the years, from the 38" 1600p ones to these 40" 5k2k ones. I have 2 of these 4025's, one on top of the other and when I'm gaming on PC, I switch the Mac to mirror the screens and I change the input of the bottom monitor to the PC. I keep an eye on my mac on the top screen and either use separate kb/mouse or sometimes I use Synergy although I find it to be a bit buggy. I don't find the response time to be an issue but I also don't play a lot of twitchy fps games. 🤷♂️ Currently playing TLOU2 and it's gorgeous on this display.
r/ultrawidemasterrace • UltraWide for Programming on a Mac and gaming on a PC? ->I have two 4025's one on top of the other... both on my macbook during the day, and I switch over the bottom one to pc for gaming. Playing TLOU2 on it right now and it's gorgeous. I don't really notice any smearing, or if I do it feels like just slight motion blur that most games push on you anyway. 😀
r/ultrawidemasterrace • Best productivity (70%)/gaming (30%) monitor at the moment 38-40"? ->I’m the same scenario right now. My final two options are the Dell U4025QW or the LG 5k2k Oled. How is the text clarity on the LG oled? That’s my once concern along with the lack of kvm
r/ultrawidemasterrace • Best productivity (70%)/gaming (30%) monitor at the moment 38-40"? ->Yes I saw this along with their new video today. Might be better to stick with the dell. But the OLED seems so nice
r/ultrawidemasterrace • Best productivity (70%)/gaming (30%) monitor at the moment 38-40"? ->Yes, also Monitors Unboxed posted new video on the LG 5k2k today. They were saying that the curve is very noticeable and the fact that it is is OLED just isn't made for productivity. I do lots of video editing and I would be worried that the timeline could burn in. As much as I want that OLED panel, the more sensible choice may be the Dell
r/ultrawidemasterrace • Best productivity (70%)/gaming (30%) monitor at the moment 38-40"? ->I just got the Dell 5k2k 40inch but this one has OLED and got me all interested in it. It’s also slightly bigger too. And that button switch for a higher refresh rate is a welcome function.
r/ultrawidemasterrace • [Real-User Invite] LG UltraGear 5K2K GX9: The Ultimate Sweet Spot of UltraWide OLED Gaming Monitor ->I'm going back from a single ultrawide to a dual monitor setup. By adding another ultrawide. My 40" Dell will move to the top and at the bottom I'll add an LG Ultrasharp 45".
r/ultrawidemasterrace • AS A DEV - ->Honestly, going back and forth from 4K on my Dell U32 32" Ultrasharp to 3840 x1600 on my 38" Alienware can be quite the difference, particularly in text clarity. When I only had the Alienware and it was an appropriate distance away, it wasn't noticeable, but as soon as I got the 32" Ultrasharp to play with, the text immediately appears more soothing to the eyes and going in the other direction is fairly jarring. Of course the 144Hz refresh rate of the Alienware makes the experience much smoother. And I absolutely notice the difference in brightness/nits during the day - the Alienware is much brighter. In short, if it were 4K, I think it'd be the perfect monitor and that's sort of what you get with the U4025, with the added benefit of the dock. I would choose brightness, refresh, and customer service of the Dell over the LG any day of the week. Particularly with regards to the latter, Dell has an outstanding premium panel exchange warranty whereas customer service with LG seems to be rather suboptimal. Only thing I'd caution is considering whether a curved screen will be appropriate for your CAD work case. From time to time, I do notice when working in Excel or other docs on my Alienware that the lines I'm drawing or looking at aren't 'straight' and it can be ever so slightly annoying. It's actually why I decided to experiment with the 32" Ultrasharp. Your eyes eventually adjust and trick your brain into thinking that the curved line you see on the Ultrawide is indeed straight(ish), and then when you look at a flat screen, the flat screen will look convex. I would imagine that this would be far more annoying in CAD visuals, but I don't spend a ton of time on graphics so not sure. If the cost of the Dell is tough to swallow, you could always consider getting 2x32" 4K displays. Could be cheaper with even more real estate and same vertical resolution. Just don't forget to factor in the theoretical cost of the dock in the comparison. Good standalone Thunderbolt docks aren't cheap.
r/ultrawidemasterrace • 21:09 Dell vs LG - what monitor to pick? ->I love my Dell u4025qw, but partly because of the KVM switch that responds to DDC. Of course, it's only 40 inches and not OLED, so in a few years I'll be looking for a replacement. If the LG 5K2K offerings had KVM, I would be interested.
r/ultrawidemasterrace • [Real-User Invite] LG UltraGear 5K2K GX9: The Ultimate Sweet Spot of UltraWide OLED Gaming Monitor ->I just bought a Dell U4025. It is wonderful. When coding, it is GREAT to have height of your viewport, often even more important than width. The U4025 is 2160 pixels tall - a huge step up from the 1440 I used in my previous widescreen. I don't think it is the best choice for gaming. What is your game:non-game ratio? Mine is realistically 1:99 so I went with the monitor that was good for the 99% and decent for the 1%. Now that I think about it, I will load up a game and give it a shot. Art
r/ultrawidemasterrace • Best size ultra-wide monitor for a 48” x 30” desk (Work and gaming)? ->I use a Dell U4025. I love the screen, size and format as well as the built in KVM. I connect using TB with my Mac and DP with my PC. Since I bought the MM4Pro, I seldom use the PC. Art
r/macmini • Ultrawide monitor for Mac mini ->Bad timing, Samsung Australia just finished an EOFY sale including monitors. I have and like the lg 38wnc monitor. Great for productivity with some extra vertical height (1600px) and good for gaming with up to 144hz. Not oled good but still good. I was very tempted by the lg oled 45 with 5k2k res, but it’s expensive and not sure how it would be for productivity. If I didn’t care about gaming the dell 5k2k 40 inch looks great but it has slow response times, so not useful for gaming.
r/ultrawidemasterrace • 34” or 38” ultra wide monitors recommendation ->Finally, LG! I can finally give my Dell U4025QW to my wife. Almost bought the LG UltraGear 39" OLED Curved, but glad I waited
r/ultrawidemasterrace • LG Unveils World’s First 5K2K OLED Ultrawide Monitors At CES 2025 ->Cosigning the U4025QW. I have it (on the Dell arm) on a 46"W desk and it's not only the widest I can go given these dimensions, in terms of LCD, it's probably one of the best for and mostly work use case. Only issue that high FPS games like Valorant might not look great on it with the response rate. I noticed it on Rivals. It doesn't look bad, just doesn't look great.
