Working with a 2020 MacBook Pro 4TB on Sequoia 15.6. In the past I have edited EDID override plist files to get custom resolutions and HiDPI on external QHD displays. I have also used BetterDummy/BetterDisplay to achieve this, but that app no longer works with Intel Macs (according to the developer, at least not for getting HiDPI resolutions). In the past (not sure which macOS version it changed on) you could edit display overrides in /System/Library/Displays/Contents/Resources/Overrides. It is no longer possible to do this, even with SIP disabled as /System is now read only. A workaround was to place a custom override in the folder: /Library/Displays/Contents/Resources/Overrides However, it seems that overrides in this location are no longer read by macOS. I am trying to get HiDPI (at 1980 x 1080 or 1600 x 900) on DELL P2418D and BENQ PD2500Q QHD displays. Both have worked in this was the past, with modified EDID and/or BetterDummy/BetterDisplay. Is there any way of forcing EDID override on Intel Macs running Sequoia now?

I always use a 2020 27' iMac (5k screen) in the mode of scaled resolution 2048\*1152 (<4k) with larger text so as not to exhaust my eyes. (System default is 2560\*1440, also <4k, and it can go up to 3200\*1800 with very tiny text.) But does this affect the quality of watching 4k videos? Can the screen smartly play videos at its full strength or not?

I have a 27" iMac with 2.5K built-in display resolution. Also i may replace it with a 5K/retina one. The problem is mirroring it's display without changing my mac's resolution other than it's native resolution. When I use a Thunderbolt to HDMI converter and an HDMI cable, my mac forces me to use lowest resolution between itself and my tv (1920x1080/2K). So it prefers the tv's resolution and my mac switches it's built-in display resolution to 2K and this is not what I want. So, I think about Apple TV and AirPlay mirroring. My question is: **Is it possible to mirror my mac's high resolution built-in display to a low resolution (2K) tv through Apple TV without changing the mac's resolution?** If it's possible, naturally higher resolution image will be scaled down/transcoded to a lower resolution image. Texts and details on original image will be corrupted/blurred but it's ok, I don't expect/need a super clear image on the tv. So, will Apple TV do the job, can it transcode original high resolution image to fullscreen 2K image for my tv?

When I just started using my M4 Mac mini, I was using a cheap Chinese display from Taobao with the brand name "YSNO". This display lied that it was a HiDPI display to the Mac, causing all text and on-screen elements to be giant, but still crisp and sharp. The problem this causes is that everything is humungous. The problem can be solved in the normal macOS by manually setting the resolution to a non-HiDPI one, but for some reason, the boot menu remembered the YSNO display's incorrect configuration and I can't find a way to make it forget it. When I try to open Apple Diagnostics by holding down the power button to access the boot picker, then holding down Command+D, the list of languages has a huge font size (displayed with crisp, but unwanted HiDPI) and extends past the bottom of the screen, and I can't reach the "continue" button. The text is also cut off. This problem persists on my old Samsung monitor (I stopped using the YSNO monitor), which does not show incorrect configuration. I tried running sudo nvram -c to clear the NVRAM, and I also tried running sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool NO to force disable HiDPI. None of these commands disabled the HiDPI in the boot picker and the Diagnostics mode. Is there any way I can reset the screen resolution/HiDPI setting to the display default in the boot picker and Diagnostics mode? My macOS HiDPI is already off. The only thing that bothers me are these modes. Even the Apple logo and progress bar the computer shows when it is booting is giant, as if my monitor was a HiDPI display.

Upon connecting an 3rd-party external monitor (probably not important, but it's Dell U2719D in my case) I observe that the rendering is blurry. The Displays settings show that the monitor's native resolution (2560 x 1440) is available *and set*, but the "2560 x 1440 HiDPI" is absent. I want to add this option, without use of 3rd party apps, especially because evidence exists that they aren't panacea either. The guides I saw online point to the tools like this one . Unfortunately, following them didn't produce an emergence of new 2560 x 1440 HiDPI option in external monitor part of Mac's Display Settings. Were anyone here successful in enabling HiDPI option for 3-party monitor on any M* MacBook? Thanks

In the 2013 OS X Human Interface Guidelines, Apple wrote > As the canvas size decreases, you have fewer pixels to draw, which means that smaller sizes should be less detailed. For example, the smaller size Calendar app icon is not as detailed as the larger size, where you can see numbers for the days of the month, highlights in the metal rings P. 118 I’m looking for a comparison for more their icons; mail, safari, pages. I’ve only been able to find changes over years and not different versions in the same year.

I am using an UltraWide monitor while working from home. But when I'm screen sharing, it's a weird view for the others so I am hoping to find a quick way to change my resolution to black bars on the sides and give me a more 'normal' resolution. Is there any app/script that can help me achieve this?

I'm using an old Apple 30" Cinema Display via a series of dongles: > https://apple.stackexchange.com/questions/411391/apple-silicon-m1-mac-connecting-30-apple-cinema-display The native resolution is 2560 x 1600 and works great. It may require to holding Option when clicking "Scaled" to get that resolution. Occasionally, after awaking from sleep, the monitor awakens in an ugly pixelated low resolution state. System Preferences shows 1280 x 800 as the max resolution. At this point I unplug/replug the USB-C cable. The monitor goes back to native resolution after it reconnects. I want to avoid digging behind my desk to unplug the USB-C / Thunderbolt cable. Is there a Terminal command I can run to quickly "reconnect" all external displays? I'm not interested in anything that would require me to shut down the Mac, reset the NVRAM, etc. What I want is a quick software alternative to manually unplugging the monitor.

I access my Gmail email using the browser only. It used to let me upload iPhone photos in different size (original, Large, Medium, etc.). That option is now gone and I can't find methods native to the iPhone for shrinking the image resolution. I have to go home and use ImageMagick, which is very limiting. One trick is to rotate the phone while viewing the image, which shrinks the image to fit in the screen. A portrait image is shrunk to fit in the screen while the phone is in landscape orientation, and vice-versa. I can then take a screen shot and crop away the margin, but it is *very* crude way to control resolution and the image is still several fold larger than what I can achieve with ImageMagick. Using this trick twice in succession blurs the image too much. ***I find it hard to comprehend how downsampling is not available natively. Hopefully, I'm wrong?*** I would prefer not to install a 3rd party app. **ANNEX: The process I go through when I get to my computer** Using the suggestions [here](https://www.smashingmagazine.com/2015/06/efficient-image-resizing-with-imagemagick) , I do the following in Bash (Cygwin): # Bash function definition (1 line) #---------------------------------- unset -f smartresize smartresize() { mogrify -path $3 -filter Triangle -define filter:support=2 -thumbnail $2 -unsharp 0.25x0.08+8.3+0.045 -dither None -posterize 136 -quality 82 -define jpeg:fancy-upsampling=off -define png:compression-filter=5 -define png:compression-level=9 -define png:compression-strategy=1 -define png:exclude-chunk=all -interlace none -colorspace sRGB $1; } # Invocation (only 1 file at a time) #----------------------------------- smartresize inputfile.png 300 outputdir/ The "300" in the above example is apparently the pixel width. A width of 1200 is slightly worse than attaching an iPhone SE photo to gmail as Large (the sizing capability which is now gone). It is good enough for most of my uses.

Regarding non-retina apps running in low-resolution mode on a retina display: - In the past, circa 2012 (ref ), these apps were scaled with nearest-neightbour algorithm, where 1 pixel would become a group of 4 identical pixels. Confirmed in Apple Docs from the period - At some point since then, at least by 2016 (ref ), these apps are now scaled with a bilinear (or similar) filter meaning that a single pixel does not get scaled up cleanly and the resulting group of 4 pixels is blurred with surrounding pixels So, my question: is there a way to change the scaling algorithm back to nearest-neighbour?

I've installed Steam, Parallels and OBS on my Macbook Pro M1, OSX Big Sur 11.3.1. I was doing a live, and also used SwitchResX for a moment. Then, after rebooting it, the resolution was suddenly messed up. On Settings > Displays, the resolutions listed are: 1600x100 1920x1200 1024x640 1280x800 In that order, which makes no sense. Notice the image below, where the largest resolution listed is 1280x800, while the "default" is 1920x1800: Which isn't even the right ratio. In an attempt to solve the issue, I've reinstalled the OS, but nothing changed. How can I troubleshoot this issue?

I am attempting to connect to a MacBook Pro from a Mac Pro with a 2560x1600 monitor using the built in screen sharing client. I would like to be able have the connection fill the entire screen, but currently the best I can do is set the MacbookPro's resolution to 1680x1050 which fills about 2/3 of the 2560x1600 monitor. Since the built in client is really a vnc server, I would like to be able to set the 'served' resolution to 2560x1600 instead of the native resolution of the MacBook Pro. On a linux server this would be as simple as $vncserver -geometry 2560x1600 and then connecting to the created server. Is there a way to get the native mac vnc client to do this? For what it is worth, I found the location of the client (on Sierra): /System/Library/CoreServices/RemoteManagement/AppleVNCServer.bundle/Contents/MacOS/AppleVNCServer but can't figure out what arguments it might take (if any) This post seemed to use ARDAgent to activate and configure the VNC server but did not mention anything about setting the resolution for the server.

I know less about the nuances of the pdf file format than I might like, but I'm not completely ignorant either. "Resolution" might mean something when dealing with raster images (jpg, png, etc), but the pdf file format is this mixed multimedia format that is partly vector most of the time. When I have a pdf file highlighted in Finder, I might see something like this: But on what should be a very similar pdf file, I see a wildly different resolution: This isn't of purely academic interest to me. The overweight pdfs all seem to have 2160 x 2944 resolution, and the reasonably trim pdfs all seem to have 567 x 774 resolution. I have further questions in that direction but since this is a one-question-at-a-time sort of place, I am only asking what this piece of metadata is representing and whether Finder is just pulling those numbers out of its ass or otherwise making them up from nothing. Is this something like a DPI setting compared to the width and height of the media box (or crop box, or whatever the other pdf boxes are)? Is there some deeper meaning? I would be happy with as technical answer as could be provided, as that might let me formulate better followup questions in the other forum.

I've just installed macOS 12.3, and in doing so it's removed all the resolution options for my 40" dell U4021QW monitor. I held down Option and clicked "Scaled" to set a custom resolution, but now I just see the 5120 x 2160 (insanely small), and the next one is 3360 x 1418 (far too big for me), and from then on bigger and bigger scaling options. Before this update there were many many more options in-between - here's what I see now: Is there anything I can do to get these back? I've tried installing a tool called "EasyRes" that's supposed to list all options, but it only lists the same options there too.

I am facing a lot of small annoyance with my external display (4k, 27" benq, T3 connection) like : it wakes up with the wrong resolution, the mouse feels incredibly slow (it looks like the speed is also "scaled") and some application just struggle to display higher resolution (namely jetbrains products). So, I moved back to the standard resolution… but everything is too big now. I've reduced the zoom in some apps, but the menus remain huge. So, are there any solutions (apps or whatnot) to either fix the "scaled" display issues… or to keep the standard resolution, but having slightly smaller apps ? Thanks a ton…

I have a secondary monitor connected to my MacBook, which has a native resolution of 3440x1440. When I go into System Settings > Displays the built-in display allows me to set UI scaling, like so: But when I select the external display, it only allows me to specify the display resolution, like so: How do I set UI scaling rather than resolution for the external display, is that possible?

I just upgraded to a 4K monitor. I'm trying to get the text size to be larger and the menu larger via the "Accessibility > Display" Text size setting. No matter what size I set it to, nothing changes even with a reboot. The text is still too small. I could set the display size down of course but I don't want to do that for all the pixels, just text. From what I've read, there's no equivalent in MacOS to the text rendering tweaking that Windows or even Linux allow, or at least not in the same way of working where the font rendering system itself could be controlled. I just fiigure that the Retina Display concept people would have a way to do what seems to me a pretty obvious display mode.

Im thinking to buy the mac mini m4 and connect it to my asus monitor. https://www.asus.com/displays-desktops/monitors/tuf-gaming/tuf-gaming-vg289q1a/techspec/ Since i have never had a mac, i borrowed a macbook from a friend to check the os,so i connected it to the monitor. However, in 4k resolution, everything looks tiny in the UI. Searching the web i saw that i should have some scaled option however i didnt see it. Changing to 2k everything seems big and little blurry. It is currently connected using a hdmi->hub->type c to the macbook. I tried it with opened lid. Anything that might solve it? Also, can i somehow make sure it will work good with the mac mini m4? Thank you **Update:** So I think that I understood little more about the scaling thing. However, I still dont get something. According to a YouTube video I saw, if I go to system information it should show the monitor resolution + UI looks like (image from the video): However, in my case its always the same in both. if i choose 2k both resolution and UI looks like = 2k and same goes for 4k. why?

I am having problems with my 32" 4K external monitor resolution settings. I have next options: Default profile is too big, More Space is too small. Anything in between is scaled and affects performance a lot (I get 1/3 of performance (around 20 fps) in graphical software, games). I was trying to fix the "More Space" problem. Fonts in native applications can be changed, but GUI elements size isn't. I have 2 options, I either squint to see small stuff or can not put more than 2 windows on same desktop while sitting far away from it because they are HUGE. What to do? Maybe someone had such problem, I would like to hear how you live with it. EDIT: A bit of context: Here are Default resolution (the 20cm (7.8in) ruler is for scale) This is More Space resolution: Menu bar is impossible to read

I want to increase the target resolution when exporting slides as images in PowerPoint 2011 for Mac. In other forums it says to go to Preferences -> Save, and from there you can change the dpi. Here's a fuzzy screen shot of what it should look like: Here's what I see instead: What are my options to increase the resolution/dpi?
