Maximum resolution on external monitor

wondering if anyone knows what the maximum resolution the graphics card on my emac (1.42 Ghz model) would support for an external monitor?
I am currently running a 17" monitor at 1280 x 1024 using the screen spanning doctor hack and it works well, but I would like to replace it with a 20" 4:3 display, or maybe a 22" or even 24" widescreen display.
According to Apple an external display will only support the same resolutions as the internal monitor, but using this hack more resolutions are unlocked. Am I right in thinking that this should support the same resolutions as a standard AGP 64MB Radeon 9600 ?

I would say it may be close to the powerbooks from 2004 that used the mobile version of the GPU (2048x1536 at millions of colors)

Maximum resolution for external monitor on a B570e

hi,
i've just bought a Lenovo B570e in which i've plugged a Philips 221 V. That has a nominal resolution of 1920 x 1080.
However, when I try and setup its resolution, whether it's through the native windows graphic manager or the intel graphic manager, to 1920 x 1080, nothing is displayed. I need to lower the resolution down to 1680 x 1050 in order for the lenovo to display anything on the external monitor.
am i missing something, or is 1680 x 1050 the maximum resolution for dual display?
thank you
J.

thanks for the help.

T400s max resolution for external monitor ?

Hello
What is the max resolution for an external monitor connected to a thinkpad t400s ? The reason i am asking is that:
a) Intel says: the max resolution of Graphics Media Accelerator 4500MHD is 2048x1536
b) Lenovo says: DisplayPort + D-sub dual-display output support 2560×1600 maximum resolution
What are your experiences and what maximum resolutions on external monitors have you succesfuly tried in real life ?
Would it be possible to connect a 30" monitor at 2560x1600 to a thinkpad t400s ?

i don't know and i never tried but i'm inclined to trust intel more than lenovo on this...unless the t400s has some beefed-up x4500mhd
T400s - 2815RW1 + Win7 Ultimate

Windows 7/8.1 2560x1440 resolution on external monitor.

Hello, i have macbook pro 13 (late2013), i installed windows 8.1 and connected to my external monitor with 2560x1440 resolution.But windows allow to use maximum 2048x1152.I use minidisplayport to displayport adapter and have last drivers.Now i installed windows 7, but problem is still the same.Please help.

higher resolutions require more video memory if your macbook pro don't have enough and the windows driver can't use shared video memory then likely that could be the cause

Low Resolution on External Monitor after upgrade to Snow Leopard

I recently had my Macbook Pro 13in upgraded to run OS X 10.6.3. Subsequently I have been unable to use my external BenQ G2420HD external monitor at it's full resolution. I'm using a MiniDisplayPort to VGA (D-Sub) adaptor. I have the latest firmware for the adaptor.
With OS X 10.5 on the 13in it was OK. Also with my old Macbook Pro 15 in (also 10.5 and a VGA adaptor). These allow the full operating resolution of 1920x1080.
Now the maximum I can get is 1360 x 768.
Be grateful for any help.
Paul

I'm a bit concerned it's been 2 days and I have not received any responses to this question! Does anyone from Apple monitor this list and can give some indication of how to solve the problem?

Display resolution on external monitor

I have purchased a MacBook Pro 17" and happy with the high screen resolution using it as a laptop. Successfully making my Windows desktop obsolete :-), has left me with a nice Dell 30" monitor (which have been running very high resolutions on using Windows).
I have connected the MacBook Pro 17 via Apple Mini DisplayPort to DVI Adapter and can fine chose between mirror the display or using two display mode. The MacBook Pro also detect the screen fine. But I can't get the resolution on the external monitor higher than 1280X800???? If I use the setup without mirroring, the Mac's own display fine shows 19xx x something, while not displaying an similar high resolution option for the external monitor.
What do I do wrong?
Best regards,
Torben

You need a dual-link DVI cable to get higher resolutions.

MacBook Pro (2011) won't display 2560x1440 native resolution on external monitor

I have the new MacBook Pro 15inch with 2.2Ghz quad core and an external NEC PA271W Monitor with a 2560x1440 native resoultion. I have them plugged together via the dual-link DVI-D cable but the MacBook pro will only recognize 1920x1080 as the max resolution on the NEC monitor. How can I output the max 2560x1440 resolution to the monitor?
The MacBook Pro is left open for dual screen view. Please help. Thanks!

I am surprised no one asked you the following question regarding your response.
What if I don't what 2 displays and I only want to support the external monitor? Can I be in extended mode and have only 1 display?
The reason why I ask is because I am going to buy a dock for my MacBook (2012). The dock forces the MacBook to close thereby rendering the internal display useless.
I think what I am after is some sort of "extended to external" mode.

Tecra S2 - resolution for external monitor on NVIDIA GeForce Go 6600

Hello! I'm new here ...
I have a Tecra S2 with Windows XP SP2 and graphic card NVIDIA GeForce Go 6600. Internal resolution (display of notebook) is 1024 x 768. Its work fine. But I work with an external monitor VGA with "DualView" function. It is a Samsung Syncmaster 940N.
It??s all OK (19", resolution 1280 x 1024), with my new monitor Samsng Syncmaster 203B don't work: The external monitor's native resolution is 1400x1050 but the maximal resolution available is 1280 x 1024. And so, using 1280x1024 resolution, will cause the image on the external monitor and text is not clear.
I cannot set the 1400 x 1050 resolution via Control Panel nor via NVIDIA -menu.
Graphic card drivers are updated to the last version on the Toshiba site. Graphic card NVIDIA GeForce Go 6600 is supported from my monitor Syncmaster 203B.
Max. resolution for external video of NVIDIA GeForce Go 6600 is higher as 1400 x 1050.
I need to use this new monitor, can you help me?
Many thanks in advance!

Unfortunately the Tecra S2 isn't capable to display the resolution 1400x1050.
Here are the resolutions you can use.
Support Resolution/Color(CRT)
640x480 16bit/32bit colors(Depending on CRT)
800x600 16bit/32bit colors(Depending on CRT)

Setting the resolution for external monitor

Hello all,
I just purchased a ViewSonic vx2025wm 20.1" external monitor for my PowerBook G4 1.5Ghz 12". I've scoured the discussions regarding my question, but couldn't seem to find it. So I'll post it here...
I've successly connected the ViewSonic to my PB and the image seems to display fine in "spanning" mode (ie images span over two screens). However, when I try to "mirror" (ie have the same view show on both screens) the external monitor displays a 1024x768 resolution (the PB displays this as well, but that is the optimal resolution for the 12"). My question is this: how can I mirror while having each screen display its optimal resolution (the optimal resolutions would be 1680x1050 for the External monitor, and 1024x768 for the PB).
Thanks in advance for any wisdom on this!
PowerBook G4 1.5 Ghz 12 inch Mac OS X (10.4.6) 1.25 Gig RAM

Thanks for the quick response -- and one follow-up question. Will turning mirror off (which, if I understand correctly, will place the displays in spanning mode) cause a strain on my PB? Since the PB will be supporting the displays of both the external monitor plus its own display. Does that make sense? I actually read something related to this in these discussions which is why I brought it up. I will try to locate that discussion and place a link in this thread so I can better explain.

Top screen resolution for external monitor

I have a bit of a dumb question. I have a Lenovo T410i, with integrated graphics. Is the top resolution it can drive an external monitor at 1440 x 900?
And does that mean there is no point in getting a monitor bigger than 19inches?
Many thanks,
Joe

Go to Solution.

well that really depends on what uses you have in mind. What are you going to use your external monitor for?
Personally, when i use laptop as a desktop replacement, i would usually use 2 external LCDs, usually at least 19 inch in size. Most likely i would be using a 24 inch and a 20 to 22 inch.
Currently, the 22 inch and 23 inch format have the best pricing, and most people whom purchase these monitors would take that into consideration.
The intel GPU is fine for driving these LCDs, i use my T400 to drive a 24 inch and a 22 inch.

Setting resolution on External Monitor

I have a Macbook Pro (from 2008) and a 25.5" Samsung T260HD which has a native resolution of 1920x1200.
I need to mirror the displays or at least have all icons and such on the external display. When I mirror them, I cannot get the external monitor to use it's native resolution. instead it uses a lesser setting.
Only when I have them set to display side by side does it use 1920x1200, but then I have to go back and forth which doesn't work for my purposes.
Thanks for advice!

when you do a mirror, you are asking for a 1:1 replication of your laptop screen. so, it's not feasable to have 2 different resolutions in mirror mode. it will only do whatever your laptop is set to.
the only MBP that will push 1920x1200 in mirror mode is a 17" HD or unibody 17". you will have to run in clamshell mode or in extended desktop to utilized the native res of the display.

Low resolution on external monitor using Kernel 2.6.39

First of all, I don't if this is the right place to post this thread because it involves a kernel from the AUR, but, as that kernel is the same version as the one from [testing] I thought it would be a good place. Furthermore, the thread involving intel cards, xorg crashings and kernel 2.6.39 convinced me.
That post: https://bbs.archlinux.org/viewtopic.php?id=119442
As user of the kernel26-pf package from AUR, yesterday I updated from 2.6.38 to 2.6.39. I'm also using an Intel card on my laptop but not suffering from the crashes that the other post, ¿maybe because I'm using KDE?. The only trouble I suffer so far is that the external screen plugged to the laptop is not detected with the resolution (1280x1024) as it was before. Instead that, it is forced to 1024x768 or lower.
I have tried forcing it by adding a new mode to xrandr, but it does not detect the full frequency that screen was being used before (59.9 from 60.0 or 75.0).
My xorg logs do not show nothing as xorg does not crash at all, and no graphic issues have been detected so far.
I have not tested yet the 2.6.39 kernel from [testing] as I'm reporting the issue when I have tested that is not some kernel config that I have broke but the version. (currently I'm downloading kernel26 from [testing] but I cannot test if the same happens before 3 hours or so, as I'm writing the post from college)
As this is the first time I report some issue like this, I'm kind of clueless what logs should I post here to be helpful.
EDIT: Quick test: In both kernels 2.6.39 from [testing] and kernel26-pf I can log into kde and do everything I do without problems, also, no touchpad broken.
EDIT2: It also does happen on kernel 2.6.39 from [testing]

I have tried packages on testing related to xorg or intel drivers to see if that problem was still existing. It does. Doing some research I have found that this seems to be kernel related and not a driver or xorg thing and I have found no solutions.
There are all kind of troubles with intel graphic cards and i9xx drivers:

Also, there is quite a "funny" discussion here:
http://forums.fedoraforum.org/showthread.php?t=263684
As it seems this is a kernel related problem, do we have more options than wait from upstream to fix this? Does anyone find any workaround?
EDIT: adding dmesg output when I plug the external monitor:

Help with Resolution on External Monitor

I want to set my HP Envy 15t to drive an external monitor, not as an extension, but rather as my primary monitor. My external monitor is a Viewsonic VX2250, a little older, and requires that I use a HDMI-to-VGA adapter. (The Viewsonic also has DVI inputs...not sure it that would make a difference.) On my current tower setup, I use the monitor in its recommended (or native mode) setting of 1920x1080. I like this screen a lot.
The adapter is a Bytecc HM-VGA005 and the specs seem to suggest that it can handle a variety of video resolutions - Full HD (1080p), WUXGA (1920x1200 RB mode), and UXGA (1600x1200 VESA mode).
The 15t currently runs in the recommended resolution of 1366x768. If I understand the specs right, in HD mode it's 1366x768 and in FHD mode it's 1920x1080. The graphics card is an Intel HD Graphics 4600. Is this the reason that I can only get HD resolution and not FHD resolution on the laptop?
But whenever I plug all this together and try and change the laptop screen resolution settings, the external monitor only shows 1024x768...pretty lousy. I have it so that the laptop screen is dark and only the external monitor is on. But there doesn't seem to be any choices I can make to improve this resolution. I've checked to see that the graphics driver is up to date and it is.
What do I do to get the best screen I can on the external monitor? Would buying a new monitor with HDMI inputs achieve better results? Do I need a different adapter?
Thanks...Kurt
This question was solved.
View Solution.

Me again! Well, it was a bit of the nut behind the wheel. I checked in with the store that I've been buying my cables, adapters, etc. He said to bring the Viewsonic monitor by to see what might be going on. As I was setting up, he asked about power to the adapter. I had the USB cable but didn't think it was needed. But after putting everything together in addition to power to the HDMI-VGA adapter, I could see I was getting the resolution that I was hoping for. Why it worked on the Dell monitor, no clue...maybe a better monitor or different VGA cable. The Bytecc adpater didn't come with any instructions, so I just didn't know.
All is well. Hope this helps someone in the future.

What is the max resolution for external monitors from the intel hd 4000 graphics driver

What is the max resolution supported by the intel hd 4000 graphics driver found on the 13in MacBook Pro for EXTERNAL monitors?

OK so after doing much research... this seems to be the best workflow.
Bring HDV in to FCP as ProRes 422.
Edit show... add bells and whistles, etc.
Export movie as ProRes 422.
Then for the client - ensure that they have latest version of Quicktime and download the Apple ProRes Quicktime Decoder (for mac or Windows). (It is assumed they have a decent computer to play back on.)
The client will then be able to play a movie encoded as proRes 422 and all will be happy.
As a back up a high resolution h264 file can't hurt.
Thanks for everyones input. We got there in the end.
