Blurry Monitor Issue

By BizIntelligence ·
Hi There !
I am facing a problem where monitor goes blurry after some time interval. The following are the machine details:
Dell Optiplex GX320
NEC LCD Monitor 92X

So far I have tried following things to fix this issue:
1. Tested three monitors of different make and model.
2. Updated display driver.
3. Updated BIOS.
4. Tried different resolution settings and monitor refresh frequencies.
5. Tried clear type setting. Restarted PC
6. Changed display cable and monitor power cable.
7. Dell changed motherboard Thrice.
8. Dell changed power supply and fans.
9. Changed power extension board.
10. Changed power socket.
11. Installed PCI-E Display Card.

After trying all the above steps I found the monitor gets blurry after working for a while. The only way to fix the problem is to restart pc couple of times or unplug monitor power cable and wait for few mins or let it fix itself.

It is getting very frustrated for user. So if anybody can help then it will be really appreciated.

Thanks a lot...

Resize Icons and Adjust DPI

by Jacky Howe In reply to Blurry Monitor Issue

Adjust display properties and make icons and text easier to see, by:

Increasing icon size
Changing text DPI settings to 96 DPI
Increase icon size as follows:

Right-click an open area of the desktop and click Properties.

In the Display Properties window, click the Appearance tab.

Under Font size, click the down arrow to change the font size to large or extra-large.

Click the Effects button.

In the Effects window, click to put a checkmark next to Use Large Icons.

Click OK twice to apply the new settings and exit Display Properties.
Change the DPI setting to the default setting of 96 DPI, as follows:

Right-click an open area of the desktop and click Properties.

Click the Settings tab.

Click the Advanced button.

On the General tab, click the drop-down menu to change the DPI setting to 96.

Click OK.

Click Yes to restart the system for the changes to take effect.

Thanks for your reply.

I am sorry not to mention in my initial post. I have already tried your suggestions but with no luck.

Let me clarify my issue in detail.

Display works for hours or days but one day it will make everything blurry(text, wallpaper, icons etc) on screen. It is like text are shaking(but not actually) and very hard to read.
It is not clear type or effects in display properties which is making it....

Definitely, there is something I am missing in whole troubleshooting procedure.

Cheers !

Can you change

by Jacky Howe In reply to Display settings

the refresh rate with the video software. These symptoms can appear when the refresh rate is to low.

or, on a flat panel

if the refresh rate is set too high, this can happen as well.

refresh rate

by BizIntelligence In reply to or, on a flat panel

Yes, I have tried different screen refresh rate with monitors. But truly speaking, I have not tried them long enough to see if problem comes back. So I will try setting refresh rate more than 60 (as there is no option below 60 even if you unhide modes) and use it until problem returns.

Thanks to all for their efforts.

Cheers !

If they are flat panels

by The Scummy One In reply to refresh rate

60Hz should be fine. Make sure to check the refresh rate for the monitor (what is supported). Some flat panels can have higher rates, some can be damaged (as you describe) if set to higher rates.

On a CRT, the refresh rates would be better (for most) over 70 or 75 Hz.
