In display properties under advanced, lower your refresh rate to 60 hertz. Then go up until it no longer supports it then back off a notch.

Why can't I view the entire screen on Windows 8.1. Why does it cut off the tiles on the left?


Windows 8.1 keeps adding tiles of programs that you install and all tiles/ programs cannot be listed/accomodated in a single view and so you have a scroll bar at bottom that can be used to browse through all the programs that are installed on the system.
also please try changing the display resolution to meet the best resolution (for ex: 1440*900pixels) that your widescreen monitor supports.
as that seems to be the actual issue

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

I have recently bought samsung b2230 lcd monitor . i hoped a good resolution but since the day i bought it i coudnt get the resolution that is specified. i use a pentuim 4 processor with no graphic card ....


Your motherboard does not have much graphics to support the full resolution of LCD Monitor. If you want full resolution then you have to purchase Graphics card for it.

i think your cpu settings you changed to high resolution. That resolution is not supporting by your monitor. If you have another monitor connect to that monitor to your cpu and change lo some low resolution. If monitor is not there try to boot in vga mode for that mode you need to press "F8" button on booting. It show you some modes select vga mode and boot and change the resolution and restart your system

Dell GX260 has distorted video on Dell 19" widescreen. Circles turn into ovals.


Most likely the Display Resolution is not set to a 16:9 display aspect ratio (1366 x 768 for example) if you use a 4:3 ratio on a widescreen, then everything is distorted. Make sure the display is set to the optimal resolution You can look up you monitor's Optimal Resolution here:

Are Dell monitors not compatible with older HP Pavilion Computer? I tried to connect my HP CPU to a Dell monitor and it will not recognize it at all.


It shouldn't make any difference which monitor you are connecting to any computer. In fact, I am running a 19" HP Flat Panel on my Dell Dimension 2400 right now. It is NOT a wide screen monitor as the Dell built in graphics card will not support the RESOLUTION RATIO required for the wide screen. Check what setting is "native resolution" for your monitor and see if your graphics card will support it. If not, using your old monitor, try different resolution settings. Right click on your desk top, click on properties and that should bring up the display properties box. Try a lower setting as larger settings are the ones that will give you a black screen. It will probably give you a smaller picture on your old monitor, or perhaps smaller or larger icons on the desk top. Accept the new settings, turn off your computer and switch monitors, and turn your computer back on. If you get a picture, but it does not fill the whole screen or the icons seem too large or small, then go back into properties from the desktop and try a different resolution ratio until the picture seems correct.

Monitor compatibility


It will be compatible with the system, just keep on thing in mind, whatever resolution you set your computer at you may have to keep the ratio aspect active so that way the screen looks properly displayed.

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!

You can absolutely handle any screen you want. Just make sure if its an older computer to find a VGA connection on the new monitor and that will work out perfectly fine :).
