Text "Red Shift" during vertical scrolling? I've noticed it with Firefox 27.0, Pale Moon 24,3,2, and Operax64 12.14. The text on forums looks normal until I move the vertical scrollbar with the mouse. While the text is moving it takes on a red tint. As soon as the scrolling stops, it reverts to normal color.

Pretty weird. Only thing I did lately was use a program to calibrate the Gamma.

It's gotta be that program my friend. All is normal here on Firefox 27.0.1 :)

Then again the forum subject lines are easier to read now. Maybe I'll just live with it.

It's probably due to slow video card/ display refresh response. Same happens on my old Dell LCD monitor, and as my other more modern LCD monitor died on me, I have to use my old CRT for now. Small fonts get fuzzy when scrolling but much less with some fonts then other ones.

Hmmm, I played around with Clear Type adjustment. That seems to have fixed it.

Hi friend,

Both Intel and AMD have the ability to adjust the gamma without the need for 3rd-party tools. I remember AMD had it in their CCC and Intel has it here:

I used the Intel one above, in conjunction with this test page, to optimize gamma for my viewing preferences:

@my2cents

I know. I used the AMD software first. It fixed it for a time. I saw the 3rd party tool on a download site and decided to try it. It did seem like the gamma adjustment was a bit easier to use. If your eyes are less than 30 years old you might not see the difference. But for me the 3rd party tool made it easier to detect both the state of the "dots" and the color tinge.

Edit: I see by your profile you are unlikely to be under 30, unless they had a wicked early retirement buy out or something.

You were quite observant in reviewing my profile and you are accurate in your statement that I am not under 30; however, I will tell you that I was able to retire at a very young age due to a nice buyout combined with some very lucky investment strategies. So, I'm glad the 3rd party software worked out for you but I prefer to adjust the gamma to "what actually looks good to me." The bottom line for me is "when it looks good with my eyes, then its OK." Now, if you were calibrating to be in line with what others see, then I can understand your use of a 3rd party software; however, my eyes like a gamma of 0.7 for viewing and I revert back to the driver default values when I'm building a website so I can see what others see (which is not necessarily the best viewing for my eyes).

Cheers friend!

Update: OOPS! In my previous post, I said I liked a gamma of 0.7; however, that is incorrect because that is the driver setting which really equates to a gamma of 2.2 for my eyes. I also mentioned the default driver value (1.0) which really equates to value of 1.8 for my eyes. Sorry about that.

For some reason the red shift came back. So I tried another called QuickGamma

This doesn't mess with the dots. Instead it shows the numbers. I read through all this help stuff, which was a bit confusing. But once I started to play with the Up and Down controls I saw that the Red was higher than the others. I just brought the value down until the Red was at 2.20. The red shift on scroll seems to be gone. Also the web pages look quite different. There seems to be much more contrast that before. So I'll hope for the best.

Edit: seems to be no happy medium. I get rid of the red shift, but the contrast is almost like high contrast mode. I have the screen brightness adjusted below 1/2 on the slider but the screen is still too bright. I miss my old VX900 CRT. The viewing area was a bit warped at the edges but I didn't have any of these color or contrast issues. Oh well. I'll probably end up with it back as it was eventually. :)

Edit2: I'm starting to see what you mean about the built in settings. I found the AMD Catalyst Control Center. It actually has a contrast adjustment now. btw here's the page with the smiley. There's a few good ones on it:

Hi again Milesahead,

I really don't think that adjusting gamma is the answer to your issue. [DEL]Is it only FF that is causing you grief?[/DEL] Have you tried any form of monitor calibration? Are you using a VGA, DVI or HDMI connection? If VGA, I believe an optimum clock/phase adjustment might be worth looking into. There are downloadable calibration utilities out there and some vendors (like HP) also provide them for their specific monitors. Just a thought.

Edit:
I went back and saw that you are having trouble with multiple browsers. Give the monitor calibration a shot and see what happens.


Good luck.

I did the monitor color calibration a couple of times. For awhile things seemed to be fine. Then for no apparent reason it's back to fuzzy text. I'll just have to keep at it I suppose. It's killer when there is only hw brightness control and no contrast(Toshiba Laptop.)

Hi again MileAhead,

Sorry to hear you are still having such an issue. Now, since I saw you made reference to your "laptop" in your last response, I guess all of my previous recommendations were most likely NA to your current condition. Anyway, it might be worth your while to provide a bit more background information leading up to your issue (if you are interested in sharing that information with others). Specifically, things like providing you specific model number would allow others (with the exact same laptop) to report if they are having a similar issue or if everything is fine. Once know, a stare and compare might result in a fix for you. It would also be interest to know, if it ever worked and, if yes to that, when the problem started? There has to be someone out there with the same laptop as you.


Good luck,

I updated system specs. The specific Satellite is C55D-A. The red shift issue is recent but the "fuzzy text" was a problem out of the box. I downloaded more recent catalyst software. The text sharpened up a bit after doing the color calibration including gamma adjustment. Recently it got fuzzy again. Maybe it's my eyes and not the monitor. But at any rate I see now that the new catalyst software does in fact have a contrast slider. Originally this was not available. Brightness only. The only contrast adjustment originally was to set the machine to "high contrast mode."

What I've started doing now is have the color adjustment settings in the catalyst open side by side with the browser. Move the contrast a bit this way and that.. trying to get it so it looks OK with the pages I use every day. Right clicking on the desktop shows AMD Catalyst Control Center. Those are the adjustments I'm talking about. Since contrast is the main issue the gamma corrector software that bypasses AMD settings is of limited use.

Therefore I'd say if you bought a Toshiba Satellite C55D-A with Windows 8.0 go to Toshiba and download the Catalyst software to get a contrast control for the built in monitor.

As it stands now I don't detect any color shift when scrolling. It's just a matter of zeroing in the contrast and brightness to look good across the various web pages.

Edit: sorry if I seemed to vacillate. The catalyst controls are a bit confusing as there are sections for desktop, video etc.. I finally zeroed in on the group for the built in monitor. :)

Hi again MilesAhead,

Glad you are making some progress in resolving your issue. Thanks for updating your specs too! Hopefully, someone with the same rig will respond so you can compare apples-to-apples.

Good luck my friend,
