Question about IBM P 202 21" CRT Monitor

1 Answer

Many screens on one monitor!


I have a Sony P202 21" 6558 CRT monitor (with an nVidia 8800 GTS 320 mb graphics card). It was running OK (for about 2 years) till yesterday, when I started getting 2 screens on my display. It's difficult to describe, so I've uploaded a picture below -

I'm running my monitor at 1024x768 resolution and 60 Hz refresh rate. If I increase the refresh rate, the display gets even worse - more screens. If I decrease the resolution to 800x600 (lowest) the monitor is unusable (picture starts rolling up and down quickly).

Please help!!!

    Thanks russolini.

    Since I really love the real estate on this monitor (can't afford a 22" LCD, not right now), I'm going to give it a go at the service center. Do you know what exactly the problem is, i.e., what component is faulty etc.? Any light you could shed on this, so that I know what to talk about when I speak to the technician?

    Btw, I have a temporary fix for this problem - if I change the refresh rate from the existing 60Hz to 75Hz, the display gets even more garbled when compared to the picture above (taken at 60Hz). But if I change the rate from 75Hz to 60Hz, the picture becomes normal!

    Thanks russolini. The video card didn't strike me as a potential cause of the problem, because it's less than a year old. Let me try it out and post back here.

    I tried using another monitor, and everything was fine - so I've effectively confirmed that the problem is with my monitor.

    I spoke to my technician and he told me it would be an expensive fix. Therefore, I'm right now making do with a temporary fix - I'm using RefreshForce to force the resolution/refresh rate at 1024x768 and 60Hz, which works fine for me.

    Thanks russolini for your help.

Your monitor is malfunctioning and requires servicing. Unfortunately there is no software solution, and no monitor adjustment buttons will control this problem. Due to the high cost of replacement parts and service technicians, it may be more cost effective to buy a new LCD monitor. Sorry to be the bearer of bad news :(

    That's really odd. If your refresh rate changing affects the picture positively, that might actually indicate a problem with the video card. Do you have another video card you can test in the computer, or another computer to test the monitor with?

    Before you take it to a shop, see if you can swap video cards and see if maybe the video card isn't at fault. I sure hope not, that's an expensive video card.

    If it still turns out to be the monitor, a service technician might be able to fix it, I'd suggest having them power it up and seeing for themselves - I think the technical term for what you're seeing is 'rolling', which indicates a problem with the vertical sync circuitry.

Shadow Lines Across Screen on Dell P1130 CRT Monitor

What sort of shadow lines? I assume you haven't just noticed the two horizontal lines 1/3rd up the screen from the bottom and 1/3rd down from the top from the internal stabilizing wires that all Trinitron CRTs have?

I have a Dell P1130 monitor running on Windows 2000 the adapter is a nVidia GeForce2 GTS / GeForce2 Pro. The past few days the screen is almost unreadable. It has dark lines (shadows). I tried another...

Sounds like an adapter problem.

If you have tired mutiple monitors then the card/adapter is the only problem/cause left.

You need to replace the adapter/card or motherboard (if the video is on-board).

There is not other reason. Drivers and updates will not help.

Computer Moniter screen turned purple


This is a problem with the video cards hardware or the driver itself depending on your card you should updaate your cards driver from the appropriate site,right click the desktop>properties>settings>advanced>ada... will then see the name and manufacturer of your graphic card
go to the appropriate website and download the latest driver,here are the three main graphic card manufacturers websites
1) nvidia.....
other things to check are
1.make sure your graphic card is securely fitted and if power is required to the card,then check the power connector is securly fitted and inserted
2.try changing your monitors lead from the v.g.a connector to the d.v.i connector at the back of the card,the v.g.a. is a blue connector and the d.v.i. is a white connector,and the d.v.i requires a d.v.i to v.g.a converter
3.where applicable install any monitor drivers however these are rarely required the direct x diagnostic utility,press start>run>type dxdiag >press enter,then go to the display tab and run the "test direct 3d" test
5.finally check all cables are securly fitted
if after these tests and tasks you still experience problems then change the graphics card and run the tests again,if you experience more problems then a new video/graphic card is required
any problems let me know
good luck .......
