While I appreciate the efforts to help, can anyone still replying to this thread please read it first? As we've already established, disabling it in the appearance area does not disable Cleartype in many parts of the operating system, and even the comments on that page complain about the same thing. For the time being I'll just make do with the fonts looking like crap throughout the OS since at least they're okay in my web browsers and start menu, and hope eventually a real toggle is offered by Microsoft. Maybe even in service pack one.

It doesn't seem possible to convince those who like Cleartype that to some of us it just doesn't look right. I'm using it on a 24-inch LCD that runs with a native resolution of 1920x1200, and I can still perceive the colour fringing. Indeed, even if I sit far back from my desk it still disturbs my eyes and it inevitably leads to headaches or discomfort if prolonged. I truly envy those of you who can enjoy Cleartype.

You can do that and it's one of the first things I tried, but unfortunately if you do replace with any font it doesn't seem to be displayed correctly. Specifically, it appears too large, in bold, and it'll be clipped by the window as the windows only seem to be sized to Segoe UI's scale and cannot adapt. This very frequently results in you not being able to see half of what a dialogue says, etc. But even if you do that, the parts of Windows which use Windows Presentation Foundation will still render the text in Cleartype because it's got no other font rendering technology to use. This comprises large amounts of the OS, the most obvious place being Computer (My Computer).

I think what I said managed to get lost in the fog, so I'm just going to go ahead and quote myself: And like I've also said in this thread, I am using a 24-inch Dell LCD (which has a Samsung panel), and have also tried it on a number of completely different LCDs. This is not a matter of technology, it's a matter of individual perception to the way Cleartype works, which is to put lots of little colours around all the letters. Please read the posts in a thread before responding as not doing so just adds to the massive amount of misinformation regarding Cleartype that's out there.

Oh, sorry, I didn't see the post above that one. Since I've looked into this so much I might as well briefly sum up my findings: 1. ClearType cannot be disabled throughout Windows Vista. This is because certain parts of it use the new Windows Presentation Foundation architecture, which has its own font rendering technology that only comes in ClearType. This is why even if you disable Cleartype in every single way you can think of, it'll still appear in various parts of the Vista interface. It should be noted that the ClearType technology in WPF areas of Vista is actually more advanced. 2. You can disable ClearType in most areas where you'll actually be looking at text for prolonged periods of time by changing the font smoothing to 'Standard'; you might want to improve things further by changing all instances of 'Segoe UI' in the advanced area to 'Tahoma' with a size of 8pt, as Segoe UI is only designed to be read with Cleartype enabled. The only downside to this is that Segoe UI still appears in a number of Vista dialogues and pages, and cannot be changed. Because Vista tries to apply the 'Standard' smoothing to Segoe UI which is specifically designed to be used with ClearType, it looks like absolute crap and is fairly difficult to read properly. 3. You can disable font smoothing completely, which achieves everything in (2.) but also makes Segoe UI appear without any smoothing at all, which makes it somewhat more readable but still not great. The huge downside to this is that you'll lose the XP way of smoothing, which is to let smaller fonts be un-smoothed, but smooth off bigger fonts rather than making them look really jagged -- terrible for website headers. Most people won't have browsed the web like this since Windows 98 so it might be a bit of a shock. So, the result of my findings is that the overall implementation of font rendering on Vista is s***e for some, great for others. But since Vista is meant to be good for everybody, the implementation is indeed s***e.

It's nothing to do with individual displays. It's to do with the fact that Cleartype is essentially based around the concept of people's eyes being more sensitive to changes of intensity than they are to changes of colour, meaning that the addition of red or green around all the letters is a necessary side effect of what is perceived by most people as smoother type. The one thing Microsoft didn't account for is that certain people have different perceptions and sensitivity when it comes to colour being used like this, meaning that those with above average sensitivity find the colour makes the text look blurry. Pink and green fringes on the text also often appear. It's unfortunate as the technology is in theory so good, but no amount of tuning can really make this suitable for those who find it blurry. This is why randomly enabling it on people's computers like I know some people do can be very annoying if the user doesn't know how it was done. I'm overjoyed that you're glad the OS has it all over, but really, the choice should be ours. Windows XP also let you apply it system-wide, but unlike Vista it also came in a non-Cleartype variety. Not cool.

The problem is that you can't disable it completely. I've been doing some research it and it seems it's because areas of the OS that use WPF use WPF's in internal way of rendering fonts which actually has no non-smoothed way of drawing fonts built into it. However, you can adjust a setting to remove the colour from Cleartype and thus make it greyscale, which I think is what causes the discomfort. Just a shame I can't find a way to do the same thing for the non-WPF parts of Vista. As for font smoothing, there's no way I'm disabling it completely as the XP-like method of only using greyscale anti-aliasing on larger fonts is absolutely fine. Large web headers and such look terrible when they have no smoothing. I think there're a number of things that make font viewing a bit uncomfortable for some people in Vista, and from looking around there's no way to truly get it how it was in XP. 'tis a pity.

I think it's about the eyes just as much as the PC. I've used Cleartype on basically every monitor manufacturer there is and both XP and Vista, and on neither it agrees with my eyes. Perhaps it's people with certain vision issues (I have a lazy, weak left eye), or perhaps it's related to the pixel dot pitch of the monitor, or perhaps certain people pick up on the coloured noise around the letters more than usual (I certainly do). Whatever the case, Cleartype looks like a**. I'm really unhappy that's forced upon us in Vista considering its unsuitability for various monitors and/or people's eyes. I'm glad it works well for you two though. The worst part though is that Segoe UI is also forced on us, which looks terrible when Cleartype is disabled. Weep.

Hi guys, One thing that's really bothered me about Vista is that it's seemingly impossible to completely get rid of Cleartype in an acceptable manner. There are a few approaches I've tried. At the moment I've made the registry changes and whatnot to only use XP-like smoothing, and I've used the appearance panel to change any instances of Segoe UI to Tahoma. The only problem is that Cleartype, Segoe UI, or both seem to be popping up in certain places. In Aero title bars, Segoe UI seems to be appearing but without Cleartype, making it all blotchy (as Microsoft seems to think 'optimising for Cleartype' equates to 'chopping bits out so those not using Cleartype get a messy font). I know Cleartype isn't enabled because if I zoom in using Paint I can't see the multi-coloured artefacts around the letters. In various system dialogues such as "Save File?", Cleartype seems to be enabled despite it explicitly being disabled. I know it's enabled because if I zoom in using Paint I can see the multi-coloured artefacts around the letters. A similar level of inconsistency is basically occurring across the entire OS. Sometimes it's apparently hard coded, sometimes it isn't. At the moment, in my registry I have FontSmoothing set to 2 and FontSmoothingType set to 1. Interestingly, I can actually make a few of the dialogues (such as "Run...") stop using Segoe UI if I set FontSmoothing to 1, and it seems to fall back on Trebuchet MS or something Lucida Sans Unicode -- not sure which. However, this has the doubly nasty side-effect of completely disabling font smoothing, meaning that large letters aren't anti-aliased without sub-pixel nonsense like they were in XP. If anyone has a reliable way of basically getting the font/Cleartype state of affairs in Vista into a more consistent format it'd be really appreciated. I seriously cannot believe how Microsoft has basically forced this onto people, as I'm just one of many who simply cannot use Cleartype for prolonged periods of time without discomfort, regardless of how much 'tuning' is applied. Call me mad for wanting the XP-like one-pixel-thick fonts all over my OS if you like. At least with XP I had the choice of being mad or not. Normal font smoothing without Cleartype, and no Cleartype-specific fonts that look terrible without it. Is it really much to ask for?
