Question about ViewSonic Vx2439wm 23 inch LCD Monitor

Open Question

My ViewSonic VX2439 is connected to 2 PCs, one via DVI and one via VGA. The 16:9 DVI image is always fine, but the 4:3 VGA image is randomly sometimes OK (centred), sometimes stretched across the whole screen. The manual image adjust entry on the monitor's menu has the aspect ratio entry dimmed out, so I can't set it. Tried powering monitor off/on, tried powering up each PC before the other - it seems to have a mind of its own! Very grateful for any clues as to what's happening here. BTW, the VGA output is fine when connected to a 4:3 CRT monitor.

SOURCE: getting 4:3 aspect ratio

The scaller circuitry in LCD monitors are not designed to display anything in 4:3 like a 16:9 TV will do, they are designed to fill the entire width of the screen. If you select a widescreen resolution in your display properties then your pixels will be square and images will not look stretched. The optimal resolution for your screen is 1680X1050. If you find that too stretched then you can pick something like 1280X768 but the image quality will not be optimal.

There is a chance that the video card in your Dimension 8300 is not compatible with widescreen resolutions. Determine the type by looking under graphics adapters in device manager then update the driver from Dell's website if you don't get any widescreen resolution in display properties.

If any of this sounds like giberish to you then just get me the type of video card in your system and I can help you determine if you are capable of widescreen.

If by chance your computer cannot display widescreen then I can point you to which video card upgrade would work.

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.

SOURCE: My monitor displays images in stetched full screen format

the description you gave was the long way right click on my computer, select properties then device manager, you will be in the same place but lots faster, plug and play does not identify the monitor or its compatible display resolutions, right click on the desktop select properties then display settings, go into advanced tab and look at the monitor, and the adapter, you can play with the setting until you find one that works, 1400 x 900 may not be supported by the video card(adapter) so that may be why your loosing the video settings.
hope this helps.

ViewSonic VG2030wm speakers not working


you are unable to get an image on your ViewSonic monitor, first check that the necessary cables are attached correctly and that the proper drivers are installed. ViewSonic offers drivers for download directly through its website (see Resources).

Some LCD monitors use a VGA input while others take advantage of the newer DVI interface to provide a connection to PCs (some ViewSonic monitors offer both types). When connecting your monitor for the first time, you'll need the right type of cable for both your monitor and computer. In some cases an adapter may be necessary to convert the DVI signal from your monitor to work in a VGA input on your PC.

Check that the VGA or DVI cable is tightly attached to the back of your monitor and to the back of your PC. Use the small thumb screws on the ends of the connectors to keep everything tightened in place, which will prevent the cable from getting loose.

ViewSonic monitors also use a power cable to plug into a power source. If the power light does not comes on, check that the power cable is inserted fully into the back of the monitor and that it is plugged into a working wall outlet or a reliable surge protector.

VGA connection works, DVI does not


Everything seems perfectly normal...

When you connect the computer to the monitor via an analog VGA cable, you get signal on the analog input.
When you connect them via a DVI cable, you feed the monitor's DIGITAL input, so the monitor doesn't get any signal on it's analog input, and informs you about it.
You have to select the digital input from the monitor's On Screen Menu, and then start the computer up - you should see the picture OK.
Also remember to set the display resolution on your computer to match the optimum (native) resolution of your monitor - this will give you optimum picture quality. In case of VA712B it will be 1280x1024.
Good luck and please come back with a testimonial if helped.

When dvi plug is used screen gets funny bright colored lines


FIX for design fault of ASUS VW222u Problems with monitor using dvi while vga works fine.

my ASUS VW222u had the same problem many are reporting after about 8 months
with developing colored "noise" onscreen or dancing red pixels while using dvi but vga is fine.

luckily my old man is an electronics engineer, rather than be without a monitor since vga still works fine we decided to have a look.

we worked out the problem. note: this is a fix for the random picture noise problem while using dvi port.

If monitor works ok with vga but dvi has noise then this fix should work for you.

1.open monitor (will void warrenty)
2.unplug all the the cables going to the power supply and dvi port assembly, undo two screws pull down and out you wil now be looking behind the dvi port and be holding a metal module that contails power supply and dvi- and vga port.

3.you will notice a piece of brass foil joining the earths on your dvi and vga cable this is the problem creating an "earth loop" as both vga and dvi ports are earthed to the metal casing this extra earth is causing the problem introducing noise.

3.carefully unwrap the brass foil from the two cables and seperate, insualte cables with electrical tape. (wrap around each one seperately they should now be indiivdual cables)

4.you will notice a silver spring type peice of metal on the assembly that pushes against the
main body of the unit when re-assembled. scratch the metal with a screwdriver where this peice pushes so you get a good connection when you reassemble it, do not touch as finger grease could screw up the connection. (this step is not vital just a good thing to do why your in there to make sure the the unit is properly earthed)

4.re-assemble


enjoy, fixed mine and was quite easy, take care with the plastic latches they are tight - ensure you remove all 5 screws, to see the fifth easily the monitor stand must be removed (two screws then stand slides out from rear of case)

good luck

Are you connect via Analog (Blue VGA connection) or DVI (White Digital connection?

If you are connected via DVI, then you have to change the input select button to DVI

If you are Connected VGA, make sure the system doesn't have 2 VGA ports. If it does, connect to the other port.

DVI input on monitor not working


Contacted viewsonic about this issue- they suggested- have both dvi and vga hooked up to same machine. start with poweroff on both. power on monitor, then power on computer. when you see display coming from the vga, power off pc, then disconnect vga cable, turn off power to monitor, disconnect power cord from monitor for 5 + seconds, reconnect power cord, power on monitor, then power on pc.
If this doesn't work to get the dvi working, (as happened to us) we returned our monitor for a replacement, since it was still under warranty.
