r/macminiUltrawide Monitor Options that aren't $$$
4 months ago

The problem with ultrawides are that they are mostly dual QHD monitors. That’s like having 2 1440p monitors which resolution is too low for Macs. I’ve had 1440p monitors and I can’t stand the pixelation of the screen. Macs don’t do sub pixel rendering so you’re stuck with the Macs approach for 2x resolution for its hi-res mode. High res ultrawides are quite expensive like [this 45” OLED one](https://amzn.to/4oMpOhG), [this 40” IPS one](https://amzn.to/3Xy7rll) from LG and [this 40”](https://amzn.to/4pL20eF) one from Dell.

Dell 40 5k2k. It's the best monitor out right now. https://www.dell.com/en-us/shop/dell-ultrasharp-40-curved-thunderbolt-hub-monitor-u4025qw/apd/210-bmdp/monitors-monitor-accessories? For gaming the 45 OLED 5k2k might win, but it still has a lower PPI than the 40 with the same resolution. OLED is a negative for programming as well. The 57 Samsung is a monster and their QC is substandard at best. LG also makes a 40 5k2k, but it's only 72hz. That what I use and it's great. No issues and I'm in text all day like a programmer.

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.

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/ultrawidemasterraceBest 5k 38 - 40" monitor for office work?

Dell U4025Q would be your best choice if budget is not a problem. There is a newer 52" one too. For a cheaper VA option, the G75F is a 40" 5k2k monitor ideal for office work. Been using mine for last 2 months with a Mac.

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

Yes I saw this along with their new video today. Might be better to stick with the dell. But the OLED seems so nice

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

I was lucky and found the Dell U4025QW for £1,050 in the UK refurbished on the Dell UK Outlet website (on 25th January). It was the only one in stock and I haven't seen it in stock on there since, but it's worth keeping a lookout there (if there is a Dell Outlet store in your region).

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.

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

Just bought it, and thinking whether to keep it. Cannot really have 3 windows side by side, only 2, each of which is more narrow compared to my previous 2x27 4k. Contemplating 57" one despite it seeming too bulky

r/ultrawidemasterraceUltra-wide 120Hz+ monitor for M1 Pro?

As a Mac user I'm sure you appreciate how shit MacOS looks at low DPI vs "retina" high DPI... In my view, for a Mac ultrawide, only the Dell U4025QW would cut it for that job (UW + 120 Hz + retina + IPS).

r/buildapc1 monitor or 2 or 3? or an Ultrawide?

Sounds like you want to buy a bunch of expensive stuff hoping to do something with it. That’s backwards, figure out what you like to do first, then buy the stuff to help you do it. To answer your question, from my experience, 3 monitors is too many for one PC, two is ok if you need lots of stuff at a time on one PC, an ultrawide is the best. Having said that, I work on Blender and play games, and for fps games I use an ultrawide 1440p, but for Blender I much prefer my 27” 4K monitor, it’s much sharper and just the right size. The only upgrade I would consider for Blender is the Dell 40” 5K ultrawide, but it’s extremely expensive.
