Hi all
I did search before posting but couldn't find anything related to my problem so I am hoping that this will help.
I have just attached an LCD widescreen monitor and I notice that the text fades from bold to light across the screen and in some cases it is tinged green. If I reduce the page from full to small and move it around the text changes strength dependant on its position on the monitor screen. :confused:
I have never had an lcd monitor before and was wondering if it is my fault in setting it up?
I am running winxp and a gainward graphics card with the nvidia Geforce chip.
I have the latest drivers for both the monitor & the card.
Any suggestions would be appreciated. thanks for your time. :icon_biggrin:

A short, practical addendum to ' original report and the observations from and .

The behaviour described can come from several different causes; the quickest way to isolate the source is a short set of tests.

  • Check whether the tint/gradient appears in the monitor's own OSD or during BIOS/boot screens. If it shows up there the issue is hardware or the video cable; if it only appears inside Windows it’s likely a software/subpixel-rendering effect.
  • If the monitor is connected with an analog VGA lead, swap to a digital connection (DVI/HDMI) or try a different VGA cable and connector. Analog sampling misalignment can produce uneven text darkness and color fringes; using a digital link removes that variable.
  • Force the display to its native resolution and recommended refresh rate from the graphics control panel, then test with full-screen solid colours (white, black, red, green, blue) and different backgrounds. That helps reveal whether the problem is scaling/subpixel rendering or a panel/cable fault.
  • Toggle ClearType and run a ClearType tuning step (the tuning tool in Windows or the ClearType tuner utility). Subpixel rendering depends on the physical subpixel order (RGB vs BGR); a mismatch can produce a coloured fringe that moves as text shifts.
  • Identify the panel technology in the monitor’s specs. Lower-cost TN panels show stronger colour/brightness shifts when viewed off-centre; IPS/VA panels keep colour steadier from different angles.

If the problem persists after these checks, the likely culprits are a failing panel, an intermittent cable/connector, or GPU output hardware — in which case manufacturer support or an exchange is the appropriate next step.

This is a function of the angle between the LCD screen and your eye. You will notice changes in these effects as you move your head around.

It is a property of the liquid crystals themselves. LC watches, LC thermometers, and Mood Rings also change color and intensity with the viewing angle.

It works best if your eyes are along a line perpendicular to the center of the screen. Also, the screen becomes more uniform with an increase of the distance to your eyes.

In case anyone else has this problem-- You could try playing with the monitor settings called something like "coarse" and "fine" (what my Samsung calls it) or "clock" and "phase" (what my LG calls it), etc. On mine changing those causes/fixes the problem you explain about the light/dark fading. Might be color settings you can play with too for your green tinge issue, who knows. Good luck!
