Question about ViewSonic VA712B 17" Flat Panel LCD Monitor

My viewsonic Va712b monitor does not allow higher resolution than 800x600 resolution

Posted by on

  • globalpath00 May 10, 2009

    I tried to change the resolutuion from 800x600 to 1024x768 but it does not allow the change. I changed the refresh rate to 80Hz and 50Hz but it always reverts bact to 800x600. Is there a trick that I can use or is this a shortcoming with this monitor. I am using winXP SP3 with onboard video (AMD 64 dual chip) 2.5 GHz processor.



    Thanks a million for your help

Ok, you need to know and to do
1) your monitor can be up to 1280X1050 resolution and automatch to destop one,
2) you need clean Rams first(reinstall Rams to make connection well)
3) the windows xp sp3 it can not support onboard VGA higher resolution without original motherboard video driver,
3) in this case your destop maybe lost the original driver so you need check the onboard video driver at hardware managment, there is a yellow mark at video device.then find a matched driver to update. still unfixed means your onboard video chips has some problem.and then
4) you may insert a AGPvideo card to AGP slot and install its driver should be fixed well.
hope to help you fixed it ,any question feedback to me please

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.

Viewsonic VA712b lost Power Supply need voltage & current


davsmith00, Did you look on rear of VA712B where the power plug enters the power JACK connector? Maybe it will only tell you who is positive and who is negative (gnd) some monitors state what is the required V & I for them on the rear labels somewhere. This will teach you not to lose your supply. Did the dog hide it under the bed? Good luck finding a replacement. There are sources on web that specialize in drop-in replacement IN-LINE switch-mode-power-supply Bricks. You can also try newark.com and mouser.com and digikey.com to see if they have something. I'm louie12fix on fixya or lmistyrel@ aim.com Bye for now.

Can't get improved resolution


You need to download the most recent video driver for the video card in the computer. Open it up, look at the video card and then google the name of the card for the latest windows xp driver.

Monitor problems


You need to change down the res. to a minor mode. i.e. 800x600 low quality. For Windows enter the protected mode - i.e. after POST (bootup) press F8 then enter with your account, or the administrator. Right-click anywhere on the empty desktop and enter "Properties" menu. Turn the screen resolution down in there (i.e. 800x600); also, check whether your current monitor is recognized by model in there. Re-adjust to a suitable working resolution. If all fails, you can also de-install the video card driver in admin protected mode to go back to basics. Of course You need to re-install it again afterwards when in your original Windows.
