Question about ViewSonic VA705b Monitor

Open Question

A ViewSonic VA705b monitor has backlight control problems

A ViewSonic VA705b monitor looks fine while displaying 1024x768x16 or greater resolution screens, but the backlight dims excessively when you switch to "text" mode, such as displaying BIOS boot messages or operating in pure text mode under Linux. It appears that the electronics in the monitor automatically adjust the backlight brightness in certain cases, and I'd like to find a way to disable that behavior if possible. I have 12 more days to return it for a refund at Amazon if the problem can't be resolved. Thanks in advance -- Rick Slater

SOURCE: Viewsonic monitor not detected after service

Hello,
If you are running DVI-D(the white connector) then it isn't getting a digital handshake. If you have inspected the connection between the 2 and make sure there is no bent pins inside the connector that it mates with. If you have another computer, try to connect to that one.
Open windows start menu, right click on my computer, then choose properties. Next choose Hardware, then Device manager. Once there, double click on display adapters to see if installed correctly. If good, click Monitors. If good, then your video card driver must need reinstall or update as usual. Also do you have the correct driver for you monitor? How does it react when you uninstall the monitor driver(can you select 32bit and higher resolution in default drivers?
If none of this works, I would suspect that the replaced component failed due to static or faulty components within the electronics.
Is there any other changes to the PC (new video card, updated Directx9.0?)

Hope this helps and let me know if I can be of anymore assistance?

SOURCE: No display, green light on ViewSonic VP201b 20.1 LCD

I have two broken VP201 monitors with different symptoms. One was black screen green light - like yours. The other was purple speks flying all over the screen., purple tint.

I swapped the power supplies and display boards, both monitors had original problems. I swap the inverters and the monitor which was black screen now appeared to work okay - but slightly pink and the monitor which was purple speks is now black screen.

I would therefore assume that both my inverters gone, one being on it's way out. You probably have the black-screen case.

I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.

They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.

Ihave viewsonic lcd monitor va1616w. Display card is NvidiaGEForce2 integrated GPU. The resoultion is not coming correctly


Maximum resolution on this monitor is 1366x768. Check your color depth( 16 bit, 24 bit, etc) and do not set the resolution greater or you will get unpredictable results.

Out of range message seen after installed new software and reboot


The monitor will display out of range message because the PC video resolution is too high for the monitor to display, the new software may have changed or corrupt the video seting, try booting up in safe mode (hit f8 while computer booting up) and set the video resolution to 640 x 480, then reboot in regular mode, then reset the resolution to the native resolution of this monitor which is 1280x1024@60Hz.

Resolution problem of viewsonic VG2021m as the second monitor of thinkpad t61p


Go into the NVidia control panel, create a custom resolution (for the ViewSonic VG2021m, you want 1400x1050, 60Hz), and test it.  When the test asks you if it looks ok and you click "yes", it *still* is not activated-- it is simply added as one of the resolutions available for the monitor, and goes back to the same setting you had before... so it looks like it didn't work.  But then, if you go under "Change resolution", you'll see your new setting is available there.  Choose it, and you are good.

It's working for me, on my T61.

VA520 Resolution Message


Have you tried via the Control Panel/Display function?  The driver provides the means but Windows provides access to those settings.

Always says: Auto Image Adjust


These are the allowable resolutions and refresh frequencies for your monitor. 1280 x 1024 @ 60, 75 Hz 1024 x 768 @ 60, 70, 72, 75 Hz 800 x 600 @ 56, 60, 72, 75 Hz 640 x 480 @ 60, 75 Hz 720 x 400 @ 70 Hz 1280x720 is invalid but I see that you were having problems at 1024x768 which might mean the refresh timing was wrong. Make sure the monitor tab in the display properties (advanced) is correctly set with 'hide modes that this monitor cannot display' so that the display is locked to the valid frequencies and resolutions. If all else fails look at the game .ini configuration settings. You might be able to set a compatible mode there. Or run the game in a window.
