    hey
    the monitor is dark but you can still see images, as time goes on(10-15 minutes) the screen gets brighter and brighter and after 15 minutes the screen stops flashing and the picture is great! this just started a couple weeks ago. Before that it worked perfect for the last 6 months. It does this even when it is not connected to the computer. at startup the digital/analog box flashes and is very dark

Satservice, What happens AFTER 15 min of FLASHING?? What did unit do or act like 3-4 weeks ago? Is the screen both BLACK and BLANK? or is screen just black and you can SEE win-desktop if you shine a bright flashlight 1 inch from screen at differnt angles? Can you use your Samsung warranty? Will monitor do same when connected to different KNOWN GOOD prebooted to desktop PC? Are you refering to the "power ON" indicator light on front BEZEL as the FLASHING thing? Need more info, but I suspect "shutdown of units "switch-mode-power-supply" due to detection of FAULT CONDITION having been detected with other circuit or with itself. Read some of my other responses in my fixya profile that deal with BLACK SCREEN repair. If this response useful, rate on fixya. 12fixlouie

    satservice, If this unit is less than a year old, I would see to it that Samsung did the warranty repair work or do a no-charge swap for a refurbed unit. Tell them you suspect unit has a "thermal intermittant solder connection in the inverter circuit, or possible problem with "cold-cathode-fluorescent-lamp" failure. If no warranty is available, then you will need to research some other options for repairing your unit. Tell me what option that you will persue to fix problem. 12fixlouie

I tried to use my acer as a second monitor and it is connected to my GTX 550 Ti graphics card just like my Benq monitor. Whenever I turn on my computer the acer monitor shows the acer logo and then s


Incorporating a second monitor is a great Idea, I've used three to four on my workstations for many years. Setting up multiple monitors involves more than just hardware, the card manufacturer's software and operating system is involved. Since you didn't note the OS, I'll assume Win7. First, simply right click the desktop, and select "Screen Resolution" to see a page headed "Change the appearance of your displays," below which show be a graphic that shows both monitors with a number "1" and "2" on each. Arrange them by dragging and dropping them to reflect your physical arrangement. Then, select the fourth drop-down titled "Multiple" Displays" and select "Extend desktop onto this display," then click the "Apply" button followed by the "OK." button. If your hardware and drivers are set up properly, you should have everything working at this point. Your Nvidia software should have installed a control panel item that you can use to make tweaks to your system. You can also contact Nvidia technical support for more detailed, OS-specific assistance.

Change the resolution on my Samsung B2030 LCD Monitor


1600X900 is a higher resolution than that of 1280X1024. Therefore 1600X900 is a better resolution. If you would like to run at the lower resolution simply right click your desktop screen and click properties. Then on the settings tab use the slider bar to adjust the resolution. Lower to the left and higher to the right. If the desired resolution is unavailable then you could try downloading and installing the latest drivers for your graphics card installed in your computer.

Your card will either be AMD/ATI Radeon or Nvidia. You will need the model number of the graphics card, the latest drivers may increase resolution support for your card.

Also look on the bottom right hand side of your screen for an Nvidia Control Panel logo in green. Right click it and select the option to "change screen resolution" This may provide you with additional resolution options.

Take care!

I have a hp 8000 with a nvs 290 but I have a green tinted monitor?


Hi,

A green tint is usually caused by the monitor cable either being not connected properly or being damaged (perhaps a bent pin?).

Please try the following steps:

1) Make sure the monitor cable is securely plugged in at the monitor and the graphics card
2) Try a different monitor cable
3) Try the same cable with a different monitor

If all 3 steps give the same problem then it may be a graphics card driver issue.

You can try installing the latest Nvidia drivers from www.nvidia.com

Please rate my answer if it is useful.

Many thanks,

Chris

Hello ghinea18, sorry you can't do that because this will cause hardware conflict, that's why motherboard bios automatically disable integrated graphics if you install video card using pci express x16 slot - Nvidia GeForce 7300SE. do you know if your video card has dual vga or dual dvi connection?

You can try dual display, im not sure if this card supports dual monitors because nvidia online specs does not show full specs on 7300se series. \

Good Luck!

Nvidia F5200


You could try right-clicking your desktop and going to settings. There you need to select the other (grey or a 2 in it) monitor and select "extended desktop". If that doesn't help, check the monitor cable. (maybe try another one, you never know...)
If it's still not detected, you could look around the NVidia control panel (I myself have always had ATi graphics cards) for a "detect monitor" option.

Have a new 23 inch samsung monitor that requires res 1920x1080


The problem is the cable connection to the video card.
When using the DVI output of the FX 5500, the maximum screen resolution that you can select is 1280 x 1024.

But, if you use the Analog (VGA) output, the card will support resolutions up to 2048 x 1536, which should be ok.
