If the screen is getting dim to the point where you can't read it, it might be due an intermittent backlight. If this monitor is really only three weeks old, you might consider returning it to the store where you purchased it and exchange it.

The auto-darken feature(monitor goes dark on dark


In your monitor panel you'll find 4 buttons. Press the menu button and get into Magic Bright. There you can choose the one that best suits you. You can even set to Dynamic contract where the monitor adjusts the brightness according to the elements on the screen

Monitor shuts off and on


I had the same problem, so I switched the Auto Source feature to "Manual" and so far it's working fine for the past 2 days, if I run into the problem again I'll update this message.

On the side panel of your monitor, press the top button to access the menu, scroll down to the setup menu (by pressing the 3rd button down on the panel), press the 4th button down to enter the setup menu, scroll down to "Auto Source", use the 4th button to select, "Auto" & "Manual" are your choices.. press the 2nd button down to select "Manual" then the top button to exit the menu(s).

This monitor is set up to be able to do multi display with the software included. Utilizing both Digital and Analog signals. I'm not using this feature so I'm not sure how switching the Auto Source off will affect the performance of this feature.

Repair samsung SyncMaster 175v lcd flat screen went black right after it start


usually that is an indication that the back lights on your monitor is not illuminating your screen.... here's a test start up your machine and look at the monitor real close.... or shine a flash light at it... you may see your desktop afintly... which means your monitor may need a new inverter board or possible to change some capacitors on it.

you can also try another monitor just to make sure it is ur monitor which is problematic

Samsung SyncMaster 931BF 19" Monitor. Screen was working fine. But now after raising the resolution past 1280X1024, the screen wouldn't display anything. I tried it on my older monitor, a CRT. It...


This is because your screen is not compatible with any resoultion past 1280 x 1024. Look at your screen's specifications here: http://downloadcenter.samsung.com/content/UM/200602/20060210090838125_BN59-00521A-01Eng.pdf (Page 76 listed as Maximum resolution)

If you want to go past that, you must purchase and/or use a different monitor. Just be sure to look at the Maximum Resolutions BEFORE you purchase a new monitor!

My acer laptop with windows xp will not allow me to select the optimal resolution for my samsung moniter. How do I fix this?


The Samsung SyncMaster 730b is a 17-inch analog and digital TFT-LCD monitor delivering crisp, clean text and bright, vivid colors. This display offers a 600:1 contrast ratio, 300 cd/m2 brightness, 1280 x 1024 resolution, 160/160 degree viewing angle, scanning frequency of 30-81 kHz horizontal and 56-75 Hz vertical and 0.294mm pixel pitch
The SyncMaster 730b display offers the option of using either a digital or analog interface for viewing images and text. The Digital Video Interface (DVI) ensures a shaper, cleaner image and a more accurate representation of the original video source. Since video starts out digital in a PC graphics card, the digital output is directly interfaced to the digital input of the LCD panel and always provides the optimum quality image. In addition, no adjustments are required with a digital display, even when randomly changing resolutions. Input connectors for this display include 15-pin D-sub and DVI-D. Available in black, the SyncMaster 730b delivers a maximum of 16.2 million colors. The monitor is Windows Plug and Play DDC 2B compatible
The important stuff here would be the following:
(1) 30-81 kHz horizontal and 56-75 Hz vertical
(2) SyncMaster 730b delivers a maximum of 16.2 million colors
(3) 1280 x 1024 resolution
nVidia card settings should not exceed these monitor parameters. The monitor is not designed for more performance output without increasing liability toward failure. ?. Put your card settings, under the nVidia tab, at the following:
(a) Refresh rate set at 75 Hz
(b) Set colors at 16 million
(c) Set resolution slightly less than 1280 x 1024
It?s quite possible your monitor is at fault, but start with its optimal parameter settings for the display card first. The display card probably exceeds the monitor?s capabilities. Hopefully, this will stabilize your PC session and the blank outs cease if hardware is not faulty
