Question about PC Desktops

1 Answer

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 worked fine, at all resolutions. When I connected back to the Samsung, I saw that the screen was displaying but it was just VERY dark and dim. I tried pushing the button for brightness, and I saw a faint box with the words "Brightness not Available." The Auto Adjustment Feature Button works but it doesn't solve the darkness problem. I've tried connecting through VGA (Analog) and Digital (DVI). None work on the Samsung. The older CRT model only has an analog output and it worked. Help please. THanks in advance. Help me please. Thanks in advance.

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!

Monitor flicker


Have you updated any software, drivers, any hardware changed? Have you reseated the monitor cables? Changed the resolution? When it's in safe mode the resolution is different, you can check it in Display Properties, by right clicking an open area on the disktop and selecting Screen Resolution, then boot to normal desktop, check screen resolution.

When i put pc on this message comes up on screen saying input not supported and it floats round in a little box.


Hello,
This generally means you have the display resolution set higher then the monitor can support. To fix this press F8 after you turn the computer on. You may have to press it a couple times before the windows loading screen. A black menu will come up. Select safe mode. Your PC will load into safe mode with minimal drivers and settings. Go to the control panel and select display. Change your screen resolution to something lower then the setting is is at right now. If your screen is 19" or smaller try a setting of 1024x768 for starters. If its 20" or higher try 1280x1024 for starters.
Regards, Chris

White and red box saying out of range


The resolution of the display is set higher than what your monitor can support. Boot into Safe Mode, Right click on display, Properties, Settings, at Screen resolutions select the default resolution of your monitor 1024x768 or 1280x1024, depending on the version .

What is the biggest wide screen monitor can I get to use with the Dimension 2400 and the integrated video?


The monitor (19-inch, non-flat screen, 0.24 dot pitch) presented a more than acceptable image, even at its maximum supported resolution (1600X1200 @ 75Hz). We settled on a more reasonable 1280x1024 @ 85Hz as our preferred setting. According to the documentation, the recommended resolution is 1280x1024 @ 75Hz .Many of the newer LARGE monitors are limited to 60Hz and/or a larger dot pitch...So..look for a low dot pitch(below 0.27) and the ability to run at 1280X1024@75Hz . Passed that, the size is up to you.

Screen says mode not supported h:53.4khz v;84.ghz


You should reboot your computer. Immediately after you see the BIOS splash screen (Dell, Acer, HP, etc...) start pressing the F8 key 2 times every second. If you're quick enough, you'll get the Windows boot menu. When you see the menu, select "VGA Mode". This will boot Windows with minimal video settings which are compatible with all modern monitors.

Once Windows loads, right click on the desktop, select Properties, go to the Settings tab, and begin sliding the resolution bar up from 800x600 and clicking Apply. After each change, it'll ask you if you want to keep the settings. If you can still see the screen, click Yes. If you get to a setting where your monitor goes black and says "mode not supported", then wait 15 seconds and it'll revert to the last mode that worked. Leave it there.

Here are some typical resolutions for monitors:

17" = 1280x1024
19" = 1280x1024
19" widescreen = 1440x900
21" = 1600x1200
24" = 1920x1200

Hope this helps!

I have an error message on my screen which ios moving around. It says - 'not optimum mode. Recommended mode : 1280 x1024 60Hz'.


Sounds like you have an LCD monitor. LCD monitors look best in their native resolution. Yours must be 1280x1024. You need to (assuming this is a Windows PC) right click on the desktop and choose Personalize, Display Settings (Vista) or Properties, Settings (XP or older). Set the slider to 1280x1024. It'll confirm the change and then the message should never reappear.

I have the samsung syncmaster 913v 19'' lcd monitor.Recently,the thing blacks out after 1 hr or so and the not optimum mode signal appears.I cannot raise the resolution above 1024x768 without blacking out...


It seems like a lot of people have experienced this issue after a year or two of use. There are two things people reported working...

Try adjusting the refresh rate higher or lower... 60Hz is usually stable in any resolution.

Completely unplug monitor for 5 minutes or longer. Seems like it works for some and not others.

Samsung has a 3 year warranty. If neither solution works, see if it is still under warranty.

Good luck!
