Problem displaying red text

post #1 of 4
Thread Starter 
First off, this site has helped me a great deal with previous small problems, be it with my old laptop or this current new machine. But I have just ran out of ideas with this current problem, and it's currently frustrating me endless.

My monitor/TV can not display Red (or some other bright coloured) text correctly, as far as I can tell. I can screen cap the screen and when viewed on another device (phone, tablet etc) it does not seem to have the problem. The text appears fuzzy/blurred at edges. As a graphics designer it is crucial for me to fix this.

I think I can conclude the problem is within the panel/cable?

I am outputting through HDMI with a XFX Radeon HD 6670.

This problem seems to be limited to text, however, as games run as they should, but in game texts have the same problem. (Bright red text against other colours would appear fuzzy)

Here is a random photo, rather than screenshot, hoping to illustrate the problem. Note that the fuzz is NOT due to incorrect focusing.



My TV is a Bush 24 LED TV. Catalyst Control Centre has set overscan to 0%. ClearType adjusted, no effect.

(Another small problem is that I can't make the Full RGB picel format "stick", as the panel/program would revert it back to last used setting, or YCbCr 4:4:4) (Running latest AMD Driver/CCC).

Any help is appreciated, and I could provide more details if needed.

1.) Maybe I am cursed, but HDMI has always caused weird display problems for me. I have had fuzzy text caused by HDMI not correctly scaling the image to my monitor. So try a DVI cable just to be safe.

2.) I have seen interference and crosstalk can cause this, but only on analog signals like VGA. I do not know if crosstalk/interference could cause a digital signal to do that. Just to be safe, make sure your using a cable with ferrite beads and adequate shielding. I do know that at some point the all digital signal is converted into analog.
(A ferrite bead is the big circular thing on cables. Here is a picture of one --> http://upload.wikimedia.org/wikipedia/commons/thumb/7/73/Cable_end.JPG/220px-Cable_end.JPG Ferrite beads help to block out noise and interference).

Also, do you have any extenuating circumstances that might cause electrical interference? Things like large motors, cellphones, or placing a wireless router too close o the monitor can cause interference. Also, using "extensions" to extend the length of your monitor cable can cause all sorts of problems.

3.) While over-clocking my card really high, I have had drivers crash..then automatically restart and cause a problem similar to what you are seeing. The problem went away when I restarted my PC. It could be a display driver problem.

Thank you for your feedback. My TV only has a VGA/HDMI slot, so going HDMI is my only shot right now since the VGA looks horrible and I current have no DVI>HDMI converter.

I don't think my cable has the bead, and this issue has been pretty much here since the day the rig arrived two weeks or so ago. There are no extension, no routers nearby and no noticeable interference.

As for the card, it is slightly overclocked. But this issue has persisted before any OCing. And same before/after driver install/update.

Other things are sharp, such as window title texts. (Well, very slightly "rainbow" effect between close texts) It is the sharp hued text that are suffering.


As mentioned in original post, has this got something to do with the fact that I can't make the pixel format changes stick? Even though in the brief moments the Full RGB sticks the situation (as pictured) persists.

Discovered it may have something to do (to an extent) the sharpness and noise reduction control on my TV.

Being a cheap TV, I have the Noise Reduction off at all cost, since it's just pure ugly blur over the pixels. I have discovered though, through turning the sharpness up A LOT, the red text/or similar become a little bit more bearable, but at the cost of other things...

Can anyone suggest a work around? As well as a solution to making pixel format stick to Full RGB in CCC?
