Viewsonic VX2233WM LCD DVI issue

I just purchased a 22" Viewsonic LCD. It is an HD1080p monitor supporting a max resolution of 1920x1080. I have it connected to an ATI x600 Radeon video card via DVI. The monitor has a DVI-D input, and the video card has a DVI-I output.

The problem I am having is that when I turn off the monitor while the computer is on then turn it back on, the monitor does not detect the DVI signal. This also happens when I switch the input source on the monitor. The only way to restore video over the DVI connection is to either reset my PC or just reseat the DVI cable.

When I boot the computer, the I get my bios screens and I have video when I boot into windows XP. I can let them monitor go into sleep mode and it wakes up fine, and really the monitor works all the time. It does not shut itself off nor have I ever lost the screen while working. Only when I shut the power off or switch inputs does it lose the DVI signal and it can't seem to detect again when switched back. I don't really think it is a monitor issue but I do not understand much about the EDID and DCC connection to know if there is something kind of corruption in its plug and play file or if its pixel timing is off.

    I have a very similar problem - my monitor (same model) doesn't turn on with the computer. I have to use a different monitor to start up, and then switch. I feel this has happened before with older Viewsonic monitors, but the fixes are many and varied. Am trying to contact their support and going through the fixes to see which one works.

SOURCE: DVI connection fault

I had the same problem, you must call Viewsonic to change your screen. The DVI input on the screen is dead.

You are having a firmware issue or the main board is bad. Since you cannot get the monitor to work from either connector, and since this is a high resolution monitor, I doubt you are having any operating system issues. You can test the monitor on a laptop or another computer if you desire, however from the symptom it looks like the main board requires some attention. Contact Viewsonic at or call their 800 number for service information. You could order a main board, but it may not have the ddc data programmed (similar to firmware) so you may have to bring it or send it to a shop for service. BTW, they have three year warranties. I would recommend calling Viewsonic.

I bought a used Dell P2211H widescreen monitor and it did not come with the driver disk- i am connecting it to a lenovo ibm thinkpad x61s - will it be compatiable and which drivers do i need to...

Generally, no drivers are needed. All you have to do is adjust the resolution of you PC from display properties after connecting the LCD as External Monitor.
Thinkpad X61S has Intel X3100 Graphics which supports the maximum analog output of 2048x1536
Whereas Dell Dell P2211H supports high-definition resolution up to 1920x1080 Max. So, I think that you can connect Dell P2211H with your PC.
Let me know if any further clarification/ assistance is required.

Hope it helps! Good Luck! Thanks for using Fixya!

Does it do the same if you hook it up to the desk top PC?
Common problem in this VX series are due to bad DC filter caps which can cause a lot of starnge symptom, see pictures here:

1920x1080 resolution-entire screen not viewable

This also happens to my vga connection to my TV.
I used my tv remote "auto" button to re-size it to fit correctly.
If your monitor/TV does not have the adjustment, you may need to
supply your vga compatible device with your monitor's driver software.
This tells your computer what monitor specifications you have.

Optimal resolution problem, edge of desktop outside screen

Your screen probably wont recognise the dvi cable if the dsub is plugged in, you will have to use the buttons on the monitor to adjust the settings to dvi rather than it automatically using the dsub. also, ever tried adjusting the aspect ratio? to make it shrink abit to fit your screen.

Cannot get correct resolution

1. It could be limitation of your video card. Older cards would not support high resolution for LCD monitors.
2. Be sure to use DVI(digital) output from your video card. You will not get a good resolution with VGA(analog)
3. When installing driver for a monitor sometimes you will get a chose to install analog(VGA) or digital(DVI) driver. Choose the correct driver.

Good luck!

Connecting dvi cable straight to acer monitor

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.

For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.

The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).

If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

Unable to have 1280x768 full screen with DVI cable

Use the menu button on the monitor itself to adjust for the screen size in DVI mode.


On your SVGA adapter, go to your display properties (right click on desktop) click ADVANCED and change the refresh rate to fix the first problem mentioned.
