Low Resolution on Second Monitor

I have a dual-monitor setup, running on a NVIDIA GTX 970 graphics card using the proprietary driver. The second monitor is only allowing me to set the resolution to 800x600, however it should support 1920x1080. I just removed Windows and installed Arch, but before while using Windows both monitors were correctly set to 1920x1080. I did some searching online, but it seemed as though most of the answers were that there was a bad cable. However, since this exact setup works fine in Windows, the cable should not be the issue.
Looking at the logs, the error that stands out is:
[ 120.965] (WW) NVIDIA(GPU-0): The EDID read for display device DFP-4 is invalid:
[ 120.965] (WW) NVIDIA(GPU-0): - The EDID has a bad checksum. The "IgnoreEDIDChecksum" X

[ 120.965] (WW) NVIDIA(GPU-0): display, and could damage your hardware. Please use with
[ 120.965] (WW) NVIDIA(GPU-0): care.
Is there any way to fix this issue, besides using the recommended "IgnoreEDIDChecksum" configuration? Setting that option does fix the issue, but the warning about damaging the hardware worries me. Thanks for any help!

Thanks for the reply. I tried following those commands, with the following result:

Screen resolution on second monitor incorrect

Hi, I just got a new 2015 MacBook Air 13".
I use a 20" VGA second monitor at work with my 17" MacBook Pro with no problems. I also use three different projectors in the building with my 17" MBP with no problem.
My new MBAir, however, will not use all the pixels available on any of these displays.
For example, on the second VGA monitor I've used for years with my 17", the MBAir displays only in a small box in the center with a few inches of black border around the display. Of course, if I set the monitor to "scale up", the screen is filled but with a pretty blurry pixelated display. Pretty unpleasant to use.
All of the projectors display at low resolution, too.
It's important to note that the 2015 MBAir should be able to handle the 20" VGA monitor with no problem. This MBAir has been shown to be able to drive a 4k display.
I can't increase the resolution under display settings. It just isn't an option. There are only two options and the one I described above (with the huge black border) is the maximum.
I've tried detecting displays repeatedly but it does absolutely nothing.
What could the problem be? I may have to return this machine if it can't be fixed.

As far as I know, that resolution isn't available through VGA. I thought you said your machine has dual DVI out... Does your second monitor not have a DVI input? If it does, why aren't you using it?

Can't get correct resolution for second monitor

I am trying to use two monitors with a Vostro 1400 (Intel X3100 video card), the problem is I can't set the external monitor to 1280x1024. Gnome's screen resolution program only let me choose from 640x480 to 1360x768. Besides the resolution of the second monitor, everything else seems to be working fine. Some relevant info:

Yes, I tried xrandr:

At first this didn't work at all, so I tried to mess with screen resolution applet and got output on the second monitor, but not at the desired resolution.
I tried running these commands again and got output on the second monitor, but at the wrong resolution. The strange part is that the resolution I want is listed by xrandr:

Setting 1920x1080 resolution in second monitor (mirror)

Hola!
I have a MacBook Pro 13'' (2011). I'm trying configure a second monitor with the Mac, the second monitor it's a Asus VH226 and Mac recognized it perfectly.
I configure the screen mode in mirror screens but the resolution of the second monitor is not the native (1920x1080). I'm confused but Mac knows the native resolution.
I select the resolution in the menu but not applied, the second monitor turns off and on again but at 1600x1200 although it is marked 1980x1080.
Thanks
PS: I bought this connector http://store.apple.com/us/product/MB570Z/A?fnode=MTY1NDA3Ng&mco=MTA4NDU0ODY

I found a solution!
First of all, I'm using this external monitor as primary monitor and there are connected to a external keyboard and external mouse.
The solution is close the clamshell and reactivate the Mac with the external keyboard, now only turns on my Asus with native resolution 1920x1080.

HDMI bad resolution on second monitor macbook pro retina

I just bought a second monitor for my macbook pro retina and connected it through a HDMI cable. To my surprise it did not play the full resolution it only plays 1360 x 768....
I already tried the alt trick when showing display preferences, but no win either. Can anyone please help? Thanks.

If you do not need the USB pass-through to the display, this MonoPrice adapter is available for under US$75:

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:
http://www.phoronix.com/scan.php?page=a … orks&num=1
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:

Low resolution on external monitor

I have a 30" Dell monitor I've been using with my previous 17" macbook pro for years. It did resolutions up to 1920x1200.
I got a new 17" MBpro today and it only goes up to 1280x800. The specs advertise that it should go to2560 x 1600
I have a mini display port to DVI adapter I am using - previous MBpro did standard dvi out.
Help please - I can't stand looking at this huge type.

That's the wrong adapter for a 30-inch display. Click here for the one you need.

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?

Low resolution when hooking monitor up to MacBookAir

I purchased an HP ZR2740w monitor around a year ago and have been using it with my circa 2007 powermac which has a NVIDIA GeForce 7300 GT card with 250mb of VRAM without difficulties at full resolution (2560 x1440). Well... I bought a 2012 mac mini (the latest) AND a brand new macbook air (2013) and using either the HDMI-DVI or the Displayport-DVI on the mini or the displayport to DVI on the macbook air the highest resolution I can get is 1280 x 720. When I go to monitor prefs there are only two options 1280 x 720 and 800 x 600. HP says it is not their monitor and I have discussed with Apple tech support and they are supposed to get back with me within 4 days. With them I reset the PRAM (or whatever its called nowadays). I find it interesting that this behavior is occuring with both the new Air and the mini. Any ideas?
BTW I have a 23" cinema display that is working fine with both. (1920x1200).
Thanks,

Welcome to the Apple Discussions.
How are you going about uploading?
Are you digging the files out of the DATA folder in the iPhoto Library Folder? If so, you're using the thumbnails that iPhoto uses for display purposes.
There are three ways (at least) to get files from the iPhoto Window.
1. Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. Show File: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
I suggest you use the File -> Export option and export the pics to the desktop. There iPhoto will make a copy. Upload that, and when the upload is finished you can trash the copy on the desktop - your original is safe in iPhoto.

Z230 with Firepro w2100 reverts to low resolution when the monitor is removed.

Hi all,Just wondering if anyone has a workaround for an issue I've found.I'm using a HP Z230 workstation that has an AMD Firepro w2100 in it. We're intending on running this machine headless and only accessing it remotely if we need to at all, however, as soon as the monitor (a HP p221 connected via a Dell DVI > Displayport adapter) is removed, and the machine is accessed remotely, it reverts back to 640x480 and becomes largely unusable for the purpose... I've read up on this a little and found that apparently it's part of the DP specification where it polls for a connected display, and if nothing is connected it will revert back for compatibility reasons, so I'm wondering if anyone knows of a way to perhaps give the machine a "virtual" display or something akin to daemontools showing the machine there's virtual DVD/CD drive to mount an image with. Hopefully someone has seen this issue and found a way around it Many thanks.

Thanks for the reply. I tried following those commands, with the following result:

Mirroring on second monitor. How?

Until we can use an external monitor, I am trying to mirror FCP X on the external monitor. I purchased a mini display to HDMI cable and it works. But...when I mirror the display, my resolution changes on my iMac. What is the proper procedure for doing this?
Best.

The two monitors have to negotiate a common resolution, so the same screen can show on both. That "same screen", or "mirroring" requires they both be the same resolution. This is normal. HDMI is not really the best way to get a second monitor hooked up, unless you're using an HDTV monitor. In which case remember that TV's, even HDTV's are of lower resolution than computer monitors, by a good magnitude.
So, do NOT turn on mirroring, no! What you want is for the second monitor to just be a second, non-mirrored monitor. Then in FCP X, go to the Window menu, and there you can chose to show the Viewer (my personal preference) or the Browser on the second monitor.
For even more real estate, I also set to use Full Screen mode at the bottom of the Window menu (Cntrl+Cmd+F)

I'm guessing that my Powermac G5 Quad running 10.4.11 does support extended desktop. My present monitor is a 1600x1200. Can a second monitor of smaller size and lower resolution work as an extended desktop?

If I run a second monitor from an iMac, will I be able to achieve a resolution of 1928x1080 which is the max resolution of my second monitor?

I am changing to an iMac later this year. At the moment I run a Sony Vaio all-in-one and use a second monitor with it. Although the resolution of the second monitor is 1928x1080, I can only get it to work at a max of 1680x1050 so it's a bit fuzzy.
My question is, when using an iMac, will it be able to support the additional monitor at its max 1928x1080?
Thanks

You are only limited by what the maximum resolution is on the external display. Look at it's specifications, then when you have connected it to your iMac look at System Preferences - Diplays - Display tab and choose the resolution on the external display.
BTW please complete your profile. It's difficult to assist you without knowing anything about your iMac. Much like asking Sally Ormond for financial advice and not telling her anything about your financial situation.

Windows 7 Laptop to external LCD monitor show low resolution

Hello,
I'm connecting my laptop to external LCD 1920*1080.
When Extend the display, each screen works with its full resolution allowed (Laptop has lower than 1920*1080 and the LCD works with resolution of 1920*1080), but when duplicate the display, the LCD has a black frame and the desktop is only at the center
of the screen and not an all the screen.
Is it possible, when duplicate the display, that each monitor work with full Resolution? or when
dup the higher resolution will be according to the lower resolution?
thanks.

IQ770 /771 setting or checking the resolution of a second monitor

Hi I have a Touchsmart 771 and would like to use a second monitor, I have a spare HP W19 monitor that as far as I can see is the same resolution as the integrated monitor ( 1440x900 60Hz). If I connect this to the external port it seems to work fine when a second screen at it's native resolution. When I use the Nvidia tool to select a clone display both displays reduce in resolution.
I can't find any way in the Nvidia tool to display what the resolution is or to be able to try and change it.
I am happy to buy another monitor if for some reason the W19 screen is causing the problem but don't wan't to spend that money to find that it does not.
Thanks for any suggestions.

I wasn't really expecting a reply - a bit of an oddball question!
Anyway, this is what I did in the end just in case anyone in the future needs it:
private boolean locationAndSizeOK(int posX, int posY, int width, int height)
        if ((width < MINIMUM_FRAME_WIDTH) || (height < MINIMUM_FRAME_HEIGHT))
            return false;
        GraphicsDevice[] devices = GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices();
        // Find out if the top left or right corner is in one of the screens.
        for (GraphicsDevice device : devices)
            // Get the bounds and the insets (i.e. task bar).
            Rectangle bounds = device.getDefaultConfiguration().getBounds();
            Insets screenInsets = Toolkit.getDefaultToolkit().getScreenInsets(device.getDefaultConfiguration());
            // Calculate visible area.
            int x1 = bounds.x + screenInsets.left;
            int x2 = bounds.x + bounds.width - screenInsets.right;
            int y1 = bounds.y + screenInsets.top;
            int y2 = bounds.y + bounds.height - screenInsets.bottom;
            // Top left corner.
            if ((posX > x1) && (posX < (x2 - SCREEN_BUFFER_X)))
                if ((posY > y1) && (posY < (y2 - SCREEN_BUFFER_Y)))
                    return true;
            // Top right corner.
            int rightCornerX = posX + width;
            if ((rightCornerX > (x1 + SCREEN_BUFFER_X)) && (rightCornerX < x2))
                if ((posY > y1) && (posY < (y2 - SCREEN_BUFFER_Y)))
                    return true;
        return false;
    }It works in all cases I require...
Cheers, Boomah.
