27" iMac non-native resolutions

So, I'm doing what a lot of folks here are doing right now, (im)patiently waiting for my new quad core 27" iMac to ship. In the meantime, I've been doing some thinking. I intend to game quite a bit on this new system, and I'm concerned about the resolution of the screen. Obviously, even with the HD4850, most games are not going to tolerate the massive resolution required of this huge screen. So obviously, to maintain decent frame rates, I'm going to have to lower the resolution. Now, I don't know much about LCD technology, but what I've heard is that how good the image quality is at non-native resolutions is dependent on the hardware in the LCD panel. From what I've heard, this is an excellent display, with all the latest bells and whistles.
So, my question, for anybody that has experience with this particular screen, or another like it, how does it handle non-native resolutions? Does it look good? Abysmal? Somewhere in between? And, if I'm going to play in a non-native resolution, I suppose my best choices would be 1920x1080 (3/4 res), or 1280x720 (1/2 res). Am I correct in that assumption?
Thanks so much for taking the time to read this, and I hope this makes for some good discussion!

It looks great. I have the 27" dual core which is the same screen. Obviously anything less than 2560x1440 resolution is going to be an interpolated resolution but the screen is extremely high quality and with that kind of pixel density to work with it's easy to make the screen look great.
Is it as tack sharp as native resolution? No, but it still looks great. I've tried 1600x900 and 1920x1200 modes which are the same 16:9 format as the native res and they look stunning even on the desktop. No worries with your gaming. Enjoy!

Non-native resolutions don't scale

I've installed Windows 7 RC on a Dell Latitude D820. There is a place in the BIOS where you define the behavior of the screen when you change to a non-native resolution. By default it should scale the image to take up the entire screen. This laptop has the Mobile Intel 945 Express onboard video. When I change the resolution below the native resolution (1680x1050) it shows in a smaller window and the rest of the screen is black. This also happens if I use a program or play a game that is in a lower resolution. I'm pretty sure this behaved as normal when I had XP installed. There is a FN+F7 key combo that is supposed to scale the picture but it does nothing for me. I've updated the BIOS to A09, updated the driver via device manager where it found an update automatically. I also tried a pre-release driver from Microsoft (8.15.10.1713) but nothing seems to fix this.

what about integrated intel gpus ??? the WDDM driver doesn't have an interface to adjust the scaling pls help i have windows 8.1 i can't install win 7 driver for my gma 4500mhd not even in test mode & stuff
What about it? This thread is not about Intel Opus. And, this is not a Windows 8.1 forum, it's a Windows 7 forum.

Bad to run screen at a non native resolution?

Hey I'm playin CS in windows and there isn't a 1400x900 resolution for it so i;m just playing 1024x768 in a window. Is it ookay if I make it full screen @ 1024x760?

Under the current OS's (Mac and Windows), displaying at a non-native resolution is "fuzzy" due to pixel interpolation. Leopard will have "resolution independence" - no fuzziness.
Um, actually the fuzziness of non-native resolutions is a physical limitation of how LCD screens work. Leopard's resolution independence refers to something quite different (the ability to scale all UI elements to maintain their size consistently across resolutions).

Windows 8.1 x64 Bit Black border in non-native resolution

Hello : i have a GMA 4500mhd GPU & i installed windows 8.1 & the default driver was fine all screen resolution havn't got the black borders but after i did the windows update it installed the
WDDM 1.1 driver. after a restart all non-native (under 1366x768) are not scaled to the monitor
.. when i had windows 7 x64 ; the recommended driver 15.17.19.64.2869 was fine
& it comes with it's own interface to adjust the options like performance & quality , scale full screen & stuff but windows 8.1 didn't let me install this driver so help me

Hello YellowMenace，
When you use the default driver, it works normally? After the Windows Update installing the WDDM 1.1 driver, the monitor resolution is changed?
Please share us a screenshot for better analyzation.
Please change the scaling option as MVP S.Sengupta mentioned.
If a new driver for your video card is causing problems, or an incorrect registry setting is preventing Windows from starting correctly, you can restart your computer using Last Known Good Configuration.

How to "un-zoom" non-native resolution screen?

With older ThinkPads, I was able to display lower resolution output on the ThinkPad LCD at a 1:1 pixel ratio, instead of having it stretched/zoomed.
On the W520, I don't seem to be able to do it. And so, the result is that the BIOS boot screen, and Windows boot GUI look rahter "blurry".
Anyone know how I can make the screen smaller again?

Someone was asking a similar question:
http://forums.lenovo.com/t5/IdeaPad-Y-U-V-and-Z-series/Y450-Screen-expansion-option/td-p/131647
It's Point 4 under section "Unsatisfactory video display on the ThinkPad LCD display":
http://support.lenovo.com/en_US/diagnose-and-fix/detail.page?LegacyDocID=MIGR-4YQHUC
How come newer Thinkpads don't have this option?
Some people like the scretched look, some don't (me being in this group). Especially in non-Windows environment, because text/fonts looks REALLY odd when stretched on a 16:9 display.

Gaming in non-native resolution @ i3 wm

whenever i exit a game that previously was running in a lower res than native (e.g. Soldier of Fortune with a max res of 1024x768), it lowers my desktop res (presumably to the game's own res) and in order to resolve it i have to call
xrandr --output <device> --mode <res>
each time.
i wonder if anybody had this before, and if so, what did they do about it?
thx in advance!

I've come to just accept that this is what happens when playing some full-screen games in a tiling window manager. It's happened in every window manager I've ever used, and I just reset the resolution when I'm done. I have a script that switches back-and-forth between my laptop display, and my laptop display plus an external monitor; I just run that after I'm done playing.
Try running games in windowed mode and using i3's fullscreen toggle. It's worked for me a couple times, and "fullscreen" games in i3 never grab the mouse and keyboard anyway, if you follow me.

Can Anyone Explain Why Using the Hightest (Native) Resolution is Preferred?

I have an '06 iMac with a 20" screen, my top resolution is 1680 x 1050, but when I try using it, yes I can "fit more on the screen", but the type is tiny, tiny, tiny, (& I can't seem to figure out how to enlarge it outside of my browsers. How do people function with microscopically small type? I have been using 1280 x 800, but am now trying 1344 x 840...
The main issue I think occurs by using the lower resolution is that my message formatting, both via Mail & when posting stuff on line, ends up all skewed, sentences break off where they shouldn't etc., as if there is some default margin that is forcing all my copy to conform to, except when I'm writing it.

Modern monitors have a fixed amount of pixels, in your case, 1680x1050 pixels. If you start sending it a signal in 1280x800 pixels, the monitor itself has to scale it up to 1680x1050 pixels in order to fit it on the screen.
You can't cleanly divide 1680 by 1280, this means that the scaled up pixels won't all be the same size. Some pixels will be wider than others.
Most people (including me) find that using a non-native resolution just looks messy.
I do agree with you that the size of everything on the screen should not be coupled to the resolution you're using on that screen. This would solve a LOT of accessibility problems for people with less than perfect eyesight.
Backwards compatibility with a lot of application frameworks and other technical things I won't get in to makes doing this very difficult (it will work for some applications, but not all, especially not older applications).

LCD native resolution not available in system preferences

I need to set my resolution to 1680 x 1050 and that resolution is not vailable. I have a original G4 Mac Mini with Tiger. The monitor has dual inputs for both VGA and DVI, sometimes it will work with the VGA input but not consistantly.
I need to use the DVI input now to leave the VGA input free for my KVM.
I have tried Zapping my PRAM multiple times, starting the Mini with the monitor unplugged, swapping between the DVI and VGA inputs on the LCD monitor, and swapping between my old CT monitor and the new LCD. None of this works.
The LCD always detects as "LCD Display".
I have been unable to find information on where the monitor resolutions are stored, one thing which I would have liked to try would be manually editing the file to the correct resolution.
What else can I try?
Thanks in advance!

Hi Brian, sorry about your issue- it's frustrating isn't it? The file you need to edit is in system > library > frameworks > IOKit.frameworks > Versions > A > Resources, and it's called IOGraphicsProperties.plist. If you activate the root user temporarily using the NetInfo Manager, you can edit the file with textedit, save it to the desktop, then drag it into the Resources folder to replace. When you look in the file, you'll see the following:
<key>gtf-resolutions</key>
<array>
<integer>640</integer>
<integer>800</integer>
<integer>1024</integer>

I had the same problem as you. I bought an Acer 22" widescreen, with a native resolution of 1680 x 1050, which wasn't "available" in the displays control panel. After some swearing and lamenting the olden days in OS9 when you could just willy nilly see all the resolutions, i added my resolution the this file and it showed up in the control panel. You'll have to monkey with it to see how it works, but basically you're going to add another 'integer' line, like so:
<integer>1680</integer>
If this is too hairy for you, or just too much trouble, i highly recommend SwitchRes. It works perfectly for this problem, and you can input the specifications for your monitor exactly and it will install the resolution so that it's available to the system. Its cheap too.
good luck to you!

External Display native resolution suddenly not available

Hello,
I'm using a Westinghouse LCM-22w3 external monitor with my MBP, connected via a DVI-to VGA adapter. I've used this computer/monitor setup for quite some time with no problem. Yesterday, I hooked my computer up to my 46" Samsung HDTV with no problem.
When I hooked my computer back up to the Westinghouse, the native resolution (1680x1050) was no longer available. Instead, the monitor hooks up at 1600x1000. Strangely, though, the EDID information appears to suggest that 1680x1050 should be available. Here's the EDID:

Any ideas? Switchresx didn't work, either

Well, you can move the file from the desktop back to its original location to at least get back to what you had before.
The file structure under Snow Leopard has changed and it's hard to keep up with this stuff. There is also now a com.apple.WindowServer.plist file in /System/Library/LaunchDaemons that you could try moving to the desktop and restarting. I dunno. Same rule applies.....if it doesn't help, move the file from the desktop back to its original location.

Native resolution of external monitor not appearing in System Prefs - Displays

I have an Acer G206HL monitor, which has a 1600x900 native resolution. It's connected to a 13" MacBook Pro (the current non-retina model) via a Thunderbolt-to-VGA cable. The MBP is running Mountain Lion 10.8.3.
When I go to System Preferences -> Displays -> Resolution: Scaled, 1600x900 doesn't appear in the list, and none of the listed resolutions are satisfactory.
Anyone know of a way to add custom resolutions to Mountain Lion's Display preferences?

I'm having the same issue with a a 2012 MBA running Yosemite 10.10.1 (14B25). I wish I could find a solution to this problem.

IMac G5 iSight - Resolution problems when using s-video output.

Good afternoon all.
I have an iMac G5 and the only video output it has is a mini VGA socket. I have used this with a mini VGA to S-Video converter cable from Apple and am getting some odd results.
The Mac is running Leopard 1.5.7 and I'm outputting to a fairly old Panasonic CRT TV.
The problem I find is that when I plug in my mini VGA adaptor to the Mac it reduces the resolution on the Mac screen down to 1024x768 (stretched). The TV outputted TV image looks great, but I can't seem to keep my native resolution of 1440x900 on the Mac display.
If I do go and change the resolution in "displays" in the sys' prefs' then it just seems to keep the 1024x768 resolution on the Mac but this time without stretching it.
Does anyone know how I can keep my Mac at its native resolution of 1440x900 while still outputting to s-video to the TV?
Any and all help will be greatly appreciated.
Thank you again in advance.
Stuart

Hi
I have the same config as you: I have been using it for years to view on my tv dvds or videos from the web.
To my knowledge there is no way to acheive what you wish: when you plug the adaptor in the mac adjust to your output source and its main display (the g5 display) will reflect that with the result that it becomes very difficult to use.
Maybe there is a way to try changing the resolution in a middlle"configuration" which would give an acceptable viewing on the tv as well as on the g5.
Personally I keep plugging and unplugging the adaptor as needed.

External Samsung 2443BW native resolution not listed

I have a 2007 24" iMac to which I have just added a Samsung Syncmaster 2443BW external monitor on the mini DVI interface. The Mac finds the monitor fine but the preferences panel only shows available resolutions up to 1680 x 1050 at 59.9 Hz rather than the 1920 x 1200 at 60 Hz which is native for the hardware and the same as the iMac panel. I am using the Apple DVI to VGA adapter for hookup and am running this on the analogue input (VGA) to the monitor. I have swapped the VGA cable with a known good one to no effect. Any suggestions fro how to proceed would be welcome. The extended desktop that is desired is usable at the lower resolution but the display is well below it's potential since it is running below native resolution. Thanks for any help offered
John

Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:
http://support.apple.com/kb/HT1379
Can't hurt to try, and apparently this has helped others recently.

Monitor's native resolution no longer available

I've got a Mini running 10.5.6 with a 22" LCD that runs at 1680x1050 natively. I recently disconnected the Mac and plugged it to my standard definition TV for some old school Nintendo gaming at 640x480 and it worked beautifully. Now, when I reconnect the Mac to my 22" LCD the native resolution is no longer available. The best I can get is 1600x1200 which is not the native widescreen resolution. At this resolution the display is stretched horizontally. I've tried using the "detect displays" button, rebooted several times, removed the monitor cable... none of that seems to help. Are there some sort of prefs that I can trash? I tried removing some files from /System/Library/PreferencePanes/Displays.prefPane/Contents/ but that only ended up making the pane in System Preferences disappear. Luckily the pane came back after I put the files back.
Anyway, if anyone can help me with this I would really appreciate it!

I tried Quix's solution but got a strange result.
I don't have another monitor, but I disconnected the plasma and used Screen Sharing to log onto the machine and set the resolution to 1280x768 (that was the closest available resolution in a very long list of choices).
When I plugged the plama back in, the image was offset. The left 1/3 of the screen was blank and only 2/3rd's of a finder window was visible. When I ran "Detect Displays" it revered to a lower resolution and only gave me 3 resolution choices.
This is really frustrating.

Unable to use external display native resolution

Dear all,
Here is the current setup I'm using :
MacbookPro 15", hi res, Mid 2010 with Mac OS 10.6.6, software up-to-date
Apple MiniDisplayPort to VGA Adapter Firmware 1.03
IIYAMA Prolite E2607WSD, a 26" monitor with native resolution of 1920x1200 @ 60Hz
When connecting the MiniDisplayPort to VGA adapter to the VGA cable, the MBP doesn't enable me to set the external native monitor resolution of 1920x1200 with extended desktop. The maximum available resolution the macbookpro is able to diaply is 1920x1080.
What I tried :
-using high performance graphics in the energy saver settings
-using clamshell mode
-using mirroring mode
-reset PRAM
-reset SCM
-delete com.windowserver.plist
-use SwitchResX.app and DisplayConfigX.app to force the native resolution
To make sure that the monitor was correctly behaving, I tried with a PC with WinXP, and I was able to get max resolution of 1920x1200 without an issue. I also tried with a Macbook 2008 with 10.5.6, and with it's own DisplayPort to VGA adapter (the "normal size" one, not the "mini" one I'm using with the MBP), and it worked as well with the native resolution of 1920x1200.
I 'm coming to the conclusion that either the minidisplayport to vga adapter doesn't accept any resolution higher than 1920x1080 or that the one I bought from Apple is not properly working, or that I should use the minidisplay port to DVI adapter (no HDMI here as an input for the monitor)...
I also browsed the forum and found a lot of similar issues, so I guess it's pretty common, but no workaround seems possible.
Does anybody in the community had the same issue and know how to solve it ?
Thanks in advance.

Hello BSteely,
I actually tried to get the EDID information and to replicate them as much as possible but everytime I tried a custom resolution, after reboot, SRX will say " the system didn't accept this setup"... and the proper resolution is not available..

Why does the MacBook Retina 15" do software scaling to the native resolution of 2880x1800?

OS X does not allow changing the viewport resolution to the native 2880x1800, and it suggests 1440x900 as a retina optimized one. This means that software scaling is done on the fly. My question is, why?
I have two suspicions:
1. Running everything at the native resolution puts a bigger strain on the GPU, hence slowing down the OS, putting down battery time.
2. The number of apps using retina-ready sprites is miniscule, hence Apple does not want to mess with the user experience. Although I doubt it, as software post-processing is done even now, and apps with non-retina sprites look slightly blurred. If the native resolution would have been used, they would just look a bit more blurry.
Just some comments:
1. Switching to the native resolution will make everything smaller, up to the point of not being usable. But this is a non-argument, as the OS could be smart enough to use bigger versions of the sprites/icons/text. Apple already demands that developers use hi-res sprites (OS X Human Interface Guidelines), hence everything could be scaled x2 and it would be the same size at 2880x1800, as it is at 1440x900 in the current version of the OS.
2. Technically it is possible, as outlined here: Running the Retina MacBook Pro at Full 2880x1800 Resolution. Have a look at the comments too, there are some interesting observations in line with this question, but no definite answers.
3. I am aware that the OS X Cocoa server is running at native resolution at all times. This question is concerned with the viewport resolution, which requires hacks to be set to the native one.
Can answer on Quora if preferred (http://www.quora.com/OS-X/Why-does-the-MacBook-Retina-15-do-software-scaling-to- the-native-resolution-of-2880x1800)

Ah right at the top.

This is a common problem with new Mac notebooks. There arre many threads on this and other forums about it.
Tae your Mac to an Apple store to be fixed or replaced.
