Hardware :: How To Cure The Blurry Display On External Monitor...
Dec 4, 2009
I finally did it... After a lifetime of Windows I've leapt from the Dark Side and am LOVING OSX... the combination of Spaces and Expose alone will save me countless hours!
I just got the VGA adapter to connect my spangly new MBP to the large monitor I used to use for my PC (no DVI capability on the large monitor, Acer x223w). Now however, I'm getting a strange and inconsistent problem:
If I connect all the cables and then power up, both my large monitor and the MBP screen appear slightly but infuriatingly blurry (see screenshot, left-hand side). If I power up MBP without connecting my large monitor and then 'hotplug' it (connecting the cable while everything is turned on), the blurryness is mostly cured - see screenshot right-hand side. The screenshot is from the same monitor in the two different states.

Together with my MBP I also purchased a MiniDisplayPort to DVI to hook up my external monitor. The graphics on my laptop are really sharp, especially with the glossy screen. Yet, for some reason, the graphics on my Samsung-monitor are extremly blurry. Compared to the MBP my 22" Samsung 226 BW seems to be very unsharp and lacks colour.

When I hook up an external monitor to the DVI output, and use both the macbook screen, and the external, the display on the external is blurry, and not very sharp. However, when I close the macbook, and run it in clamshell mode, the external becomes very clear, and crisp (like it should). I never use dual monitors, so this really isn't a problem, but want to know if its normal. 2007 Macbook Pro, 2.4, 4 gig ram. Gforce 8600M GT

I have a macbook pro and when I connect it to my external ASUS VH226H, 1920x1080 22" moitor all the fonts except the ones that are part of the OS not in external software are really blurry and rubbish. I've used the following apps and it all looks terrible: Coda, Firefox, Safari, Adium, Adobe CS5. I've tried changing the font smoothing options via terminal and it has made no difference.

I have a new Macbook Air 13", 4GB RAM, 2.13Ghz, 256GB SSD.
I'm connecting the Macbook with the Apple Mini Displayport to DVI connector to a DVI cable to a Dell 2407 monitor with a resolution of 1920x1200. The resulting image is blurry. The fonts are blurry and drop shadows on the screen flicker quite badly. The resolution on my Macbook is indeed set to 1920x1200 to match my Dell 2407.
Does anyone know what the problem could be? Is the problem with the Mini Displayport to DVI adapter?
I know for a fact that the Dell LCD and the DVI cable work fine with my Windows 7 box. I have tried two different DVI cables as well.

I'm using an external display with my MacBook Pro, using the DVI/VGA adapter.
My problem is that the display is a little bit blurry. It's not awful, but for example the display of the MBP itself is very crisp and clear so that's what I'm judging it against. Looking at text on the external monitor, some of the letters are reasonably clear, some are a little bit out of focus, and occasionally there is a fairly clear line like on the vertical of a t or an l. I'm sure there is a pattern to this but I couldn't tell you what exactly.
I'm using a Samsung Syncmaster 940NW widescreen display (the cheapest one I could find!) I have the MBP closed and I'm using Bluetooth kbd and mouse.
I've noticed that none of the resolutions available on the external display match the resolutions available on the MBP. The default res of the MBP is 1440 x 900 - I can get close (1344 x 1008, 60 Hz) to this but it seems none of the options on the display is the same as the ones available on the MBP's own display. Is this the reason for the blurriness?
I can still do work even with it looking this way, but I wondered if there's anything I can do to improve it.

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

I purchased a dell monitor a few weeks ago (s2409w), but returned it because it had a defect. I was thinking about buying a new monitor, the Dell ST2310, but I recall that on the old monitor text didn't seem as sharp as it did on my PC. It almost seemed a bit blurry.
I had it hooked up to my MacBook Pro via DVI as the main display, running at its native resolution of 1920x1080.
I read somewhere that it may have to do with the monitor's ppi, vs the MacBook's ppi, or something like that. Is there any way to remedy this problem before I buy this new monitor because I'm fearing that it will have the same problem as my old one.

I just recently got a Samsung P2450H 24" monitor and I've connected it into my MBP with a mini Displayport > HDMI adaptor and with a HDMI cable. I've changed the default setting from AV to PC in the Samsung Monitor menu as recommended by others on this forum, and now I'm getting the maximum 1920 x 1080 resolution available on both Windows 7 and Mac OS with no overscanning issues etc. Everything fits on the screen. However, the text and font on websites looks a bit jagged and a bit blurry on Mac OS and I'm not sure why. If you stand far away, it's not that noticeable, but sitting at a reasonable distance (say 2 feet), you can definitely notice it. It just doesn't look that sharp in general.
People have said HDMI connections don't work that well on Samsung Monitors and I'd be better off with a DVI connection, but I can't see why there would be a discrepancy between the two modes. Which leaves the other reason - that this is an inherent issue to do with all Samsung P2450H models being affected with Mac OS, and not the cable itself? Has anyone experienced the same issues I've just alluded to? Perhaps I'm just being pedantic, but I'm pretty sure blurry/jagged text shouldn't be a characteristic of this monitor.

I purchased a Dell 2209 WA ISP monitor, and connected it to my Macbook Pro via a DVI to DVI connection. My Macbook Pro has a GE FORCE 8600 T graphics card.
The text is quite blurry on the Dell. It is at 1680X1050 native resolution, which is supported by Macbook.

I have a VGA HP monitor that runs at a native resolution of 1680x1050 at 60Hz. I plugged the Mini in, some weird resolution came up. 1680x1050 didn't show up in "Displays". I downloaded SwitchResX, and set it to 1680x1050 at 60Hz.The resolution is now set, but the monitor is very blurry, and the dock extends beyond the bottom of the screen.I really want to get this working. I'm not quite sure how SwitchResX works so could anybody give me a hand?

I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.

The text looks a lot different from the Macbook's display. I got it to 1080p and stuff - and yes, it's showing the full 1080p. But how do I get the text to look more like the Mac's text? My Macbook display looks so much sharper. The text on the Dell looks very not anti-aliased...it isn't thick, etc.

Is there a tweak out there that will disable the internal display while using an external monitor WITHOUT having to first close the lid on my macbook because I just leave my macbook plugged in for weeks a couple feet away from my desk and it's become a hassle to first close the lid, then move my mouse, then open the lid for better ventilation. I just want to leave it open and disable the display!

I have a Dual 2GHz PowerPC with the stock video card (ATI Radeon 9600 Pro) and have had a Dell 2405FPW monitor connected to it via DVI cable and it has worked flawlessly for a couple of years... until this week.
Now the image seems to be "off" by about one or two pixels. Just a bit blurry here and there and when I move the mouse across the screen, the entire screen image seems to shift a little bit.
I've tried power cycling, re-connecting the cable, unplugging everything, resetting the monitor settings in the control panel, factory-reset of the LCD settings..
Information:
Dual 2 GHz PowerPC G5, 2 GB
Mac OS X (10.4.10)
DVI Connection to Dell 2405

I just bought a Samsung XL2370 monitor to hook onto my MBP 15".
Problem: the image is pixelated and blurry green. I can slightly see the background though. Screen works fine on a Windows pc. Before I hooked up a 19" on my MBP and that also worked.
I tried the menu but no luck. And when I choose the auto adjustment a message appears 'not available'.

I'm thinking about replacing my 24" iMac with a 15" MacBook Pro, however I'd like to keep my 20" dell monitor and use it as the primary display for the MacBook Pro, is that possible? By primary I mean having the dock and everything else on it, with the built-in display being like an external display that I can use for extra space. Also, would the same be possible at all with my iMac?

I plan to get a 13" 2.26ghz Macbook Pro, and I have a 20" external monitor with a 1680, 1050 resolution.
First thing, I've barely used OS X, let alone with an external monitor. How well does OS X handle it? Is it pretty simple, and can I set separate backgrounds for each display?
Secondly, will the GPU handle it alright, or will it be sluggish when I hook up the external? I'll mostly be using the 20" to do Photoshop work, with occasional video editing (though I have other computers available to do rendering on.)

I typed Mac Help about "to operate the portable computer with an external monitor attached and the display closed. When I close the display of my Mac Book or MacBookPro, the external monitor such as my 50" Plasma monitor or video projector would go black. I read the Help and it said and required the USB Mouse and Keyboard to close the Macbook display and put computer sleep. My question is will the Apple blue tooth or wireless keyboard and mice will work with out using the USB? Has any one try that? I am not sure if I should buy wired or wireless to operate this.

I'm looking to have a display hookup in my room for my Macbook Pro 15". I can't decide if i should get a 26" 720p HDTV with a pc input or a large lcd desktop display with a cable input to watch tv.
What are the pros/cons? Has anyone tried/preferred either? Any recommended monitors or hdtvs?

I have got my new uMBP i7. It is gorgeous, super happy with it . Because I need to run several programs under Windows XP, I have installed Windows XP under Bootcamp. I used Winclone to migrate bootcamp partition from my old MBP to the i7.My problem is that when I linked my external monitor (20 inch ViewSonic) to uMBP using the Minidisplay-to-DIV adaptor from Apple, there is no display on my external monitor. I can set the external monitor as extension of main monitor under "Setting", but after the windows Ding/Done sound, there is nothing on my external monitor. Does anyone have experiences about fixing this problem?

I am attempting to use an external DVI monitor using the mini port port and the mini port DVI adapter sold by apple. However the screen display on the external monitor does not match the Mac book display. All I get is a color Mac opening screen with no icons.apparently there is more to getting an external monitor going then just plugging it in.

I'm very disappointed in this app. For several reasons. A few of them are:
1. It randomly zooms in and out and moves around when you don't want it to.
2. When you try to go to places outside the country (like Nepal or Thailand), everything is blurry when you try to zoom in on any area.
3. When you click the "Zoom In" or "Zoom Out" button, it often zooms all the way in or out - instead of just one click level in or out.

WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

I have a 14'' iBook and recently bought an LG 19'' Widescreen monitor. I am testing a Dell 17'' on it right now before I open the LG one, but my problem is that the same screen shows on my ibook and the external. This isn't what I want. I have read you are supposed to be able to close the laptop and then it shifts to the external display but this is not working for me.
This is my goal:
Use my bluetooth keyboard full time
Have my ibook closed at all times
Have my external as my main display
How do I make this work?

My friend has a PowerBook G4 and he wants to connect it with an external 20" Apple Cinema display. His friend told him it was not possible to connect it, but I am not certain if this information is correct. He asked me to help advise him on this, but unfortunately I don't know enough about Apple hardware to give him the information he is looking for. I am wondering if anyone happens to know the answer on this.
