AMD "scaling options" problem has resurfaced. Help!

Well, let's see. For better or worse, it seems like I only ever buy AMD cards. Maybe because they are consistently less expensive for the bang. I dunno. But the drivers have this legacy issue which, every once in a while, I have to deal with.

That issue is "scaling options". Out of the box, this is set to "10% underscan", which means the desktop is blurry with pixel-imperfection and has a big black border. There is no doubt in my mind that this imbecilic default setting has resulted in literally years of cumulative lost time across all of AMD's customers. But the fix is straightforward enough: Change it to 0%. Done.

The problem, though, is that every once in a while, CCC will ignore this setting and swap back to default. Just temporarily, and often seemingly randomly. *Shrug* Back to 0% you go, CCC you rascal.

So what do you do if you've got a game which, upon switching to fullscreen mode, for whatever reason triggers CCC's propensity for ignoring your specifically-adjusted setting? You go to fullscreen, and bam, everything's blurry and there's a black border. You exit the game, and you're back to normal.

This means that CCC is making the game unplayable. And I don't have a clue what to do about it.

Would definitely appreciate suggestions. What I would really love is a hack of CCC that defaults to ZERO DAMN UNDERSCAN. Or maybe somebody can pull an AMD developer away from their doubtless fascinating Mantle work and point out that for some reason most people seem to have stopped using CRT monitors? Well, that might be a shock to the poor fellow's system so we'll skip it.
 
The scaling issue is due to HDMI. Both AMD and Nvidia will have the same issue if you use HDMI. This underscan issue is related to how TV's function, and HDMI is first and foremost a TV connection. As a result, if you use HDMI, you get underscanning by default.

Now, I don't know anything about why you temporarily have it go back to underscanning, but you might try a different set of drivers, if it is a rare thing, it may just be due to certain driver updates. That or you could just use an DVI-D connection, or displayport instead. They do not default to under scan.

Based on your observation, I just tried something out. And now I'm just confused.

First, thoughts on what you're saying. Underscan being standard for HDMI? That makes sense. That this somehow serves as an excuse for CCC's inability to maintain a setting? No. In any event, the underscan is a setting that can be adjusted quite irrespective of what output you elect to use. It is a PC- and driver-side conceit, not something that the TV is looking for.

I just swapped to using DVI-D-out from my card, and lo and behold, CCC decided it was time to switch back to 10% underscan again. And of course the problem with the game remains unfixed.

The most frustrating thing here is that while plenty of people on the net have struggled with this issue, there does not seem to be a single solid answer to the problem for those who suffer from it. (I have dealt with it on no fewer than four different AMD cards across three operating systems.) (Actually there does seem to be a kind of hack solution for people running Linux I think.)

Still hoping for a fix.

A good suggestion. Unfortunately, the only things covered by CCC's overrides are controls over the quality of the 3d rendering. The matter of scaling / underscan is, as far as CCC is concerned, something that's meant to be a universal variable. (Ironic that it doesn't work out that way.)

A little deeper research has revealed that the specific problem may be a combination of two things: 1) The already underscored technical snafu of defaulting to 10% underscan, and 2) reports that CCC enables multiple display profiles. Apparently, some games confuse CCC into believing it is suddenly displaying on a new, untested display, and voila: instant default 10% underscan. And of course since the game's output stops the moment you attempt to make a change to the settings, there is no way to change them.

I am considering borrowing a second display just to see if I can finagle a solution, in spite of CCC's best efforts to the contrary.

Aha.

The next best thing to an outright hack of CCC to override this ridiculous default setting (which is actually 8%, not 10%) is a registry entry that forces the default to something besides 8%. And such a thing exists.

While I'm glad that I can finally start playing this game, it is nonetheless bad comedy that one has to solve a half-decade-old ATI/AMD problem with what amounts to nothing less than a hack. This is why people make fun of AMD's drivers, and perhaps why Nvidia's cards can get away with being comparative ripoffs.
