r/ultrawidemasterraceDell launches the best monitor for productivity. What are your thoughts?
about 1 month ago

I'm currently using a U4025QW with 140 PPI which is enough to not get blurry text in macOS. Before, I had a AW3821DW with 110 PPI and the blurriness was quite noticeable. Curious how 129 will fare.

I have a Dell U3821DW and it’s being a nightmare to get HiDPI. I have to use a virtual screen via BetterDisplay to be able to get it, which is annoying to have to look for this alternative and have so far two minor undesired effect. As it’s a mirror, when the computer locks for idle the screen doesn’t always catch up so it’s a privacy concern depending the environment. Easy arrange doesn’t work as it mirroring the main display, and the main display does not play well together. I’ve read that this is a common issue and you need a 40 inch monitor for MAYBE to work due to the PPI count to achieve “retina” display. The monitor is worth three times the computer, and it can’t be natively used which is annoying. The computer on itself it’s amazing.

Yup had the AW3821 since it came out. Absolutely love it. I'm eyeing up the Dell 4025QW as my next monitor mainly for the thunderbolt KVM for my work laptop and remove the need for a dock

r/ultrawidemasterraceDell U4025 still the best productivity monitor?

Even on the new screens? Really wanna upgrade my AW3821DW to the LG45GX990A but I’m 70% designing / 30% gaming. I thought the new pixel density would have fixed the text issue

r/ultrawidemasterrace38” Ultrawide → 49” Ultrawide or add a vertical monitor? Productivity dilemma
23 days ago

I have the same monitor as you and I love it since it’s great for productivity. I was in a similar boat as you and what I decided was to add a 15 inch portable monitor that sits under my 38 inch monitor. It’s worked great for me. I will say is that prior to my Dell monitor, I had a 49 inch UW and I had severe eye strain, to the point I couldn’t stare at the screen more than a few minutes.

Same - I would love a replacement to my Dell 38inch UW but with a OLED panel.

You want one with a higher vertical ratio ideally, makes work much easier. I use the Dell 38" windscreen, I think the 40" is the ideal size and resolution. If you get a monitor with a KVM it makes life a bit easier

r/LinusTechTipsThey seemed more impressed by that 52” Dell monitor than they should be IMO
about 1 month ago

PPI has nothing to do with a monitor being 6K, 4K, 2K, or 1080p. It's how many pixels per inch exist in relation to the physical size of the monitor. As for it being 6K, there's no firm answers for a lot of this stuff, especially if you add in different aspect ratios. Plus, this still is labeled by marketers, not technical folk. 6K sounds bigger than 4K, the consumer doesn't care if it's "6000x3000 or more" :). I'm also not sure if a 52" panel is an even cut from the native mother glass used for these panels, if not - that'll drive up cost too. Ultimately though, not everyone who watches LTT is looking for a gaming monitor at all times. If you're too young to be, or just not in the work / productivity world yet then of course you'd have no idea of the benefits of a certain size/aspect ratio of monitor for spreadsheet or document work. I've got a 38" Dell ultrawide and a 32" Dell 16:9 on my desk. Neither prioritize gaming because most of my daily usage is work and that's all IT stuff, I don't need OLED/RGB/what have you for that. But I do need screens of a certain size to see comfortably. Anecdotally - I thought the monitor was cool because it means it will eventually go down in price and make larger size displays (which I like way way way more than 34" ultrawides that I find just wider versions of 27" screens that are small) cheaper.

r/ultrawidemasterraceWant to switch to an ultrawide for work… are there any downsides?
9 months ago

I bought the Dell S3423DWC for home and I run a 38 version at work. Connect via USBC which provides power - built in KVMs / and spend most of my time with spreadsheets and/or creating wireframes/screen designs for systems to show clients. I’ve loved it. I’ve had one “issue” if you can even call it that 1 screen sharing and showing the wireframes - if I’m on my 34 or 38 and they’re on a normal screen it’s caused a few “issues” - it’s fine you can zoom in it’s not a massive problem but worth knowing if you will be showing your designs that people will just complain that it looks to small. Just tell them to get a widescreen 😂 My main issue now is I want one that works for gaming and for work (the dell is fine but I wouldn’t mind getting something above 100hz). It’s hard to find a 34 with a KVM and geared towards gaming (or maybe it’s not and it’s just a me issue) But yeah honestly for work it’s been so good I can’t go back

r/ultrawidemasterraceThe nightmare that is finding an IPS in 2025 vs VA and OLED.
3 months ago

Same here. Need 34 - 49 in UW. But OLED burnin and text is issue. So IPS is the safe bet. I have Dell UltraSharps so looking at them.
