Monitor too dark....

I have a Gateway 400DS4 Series Laptop but my monitor has gone very very dark. The display is okay once I attach an external monitor (the external monitor works just fine). I bought a new LCD but it's still dark even after changing the LCD. Do you have any idea on the problem? My monitor is really dark. It's a sony set to XGA resolution. Trying to change display doesn't yield any brightness control

Brightness control is through the shortcut keys. You have to make sure the Gateway multifunction keyboard utility is installed for the keys to work.

Then you would use the FN key and the Up Down key at the same time.
If it adjusts up and down and is still too dark, there is a good chance that the bulbs in those screens are failing (screen may tell you if there is any pinkish tint to it or if it is dark at the bottom center when you first fire it up.
If it doesn't go dark to brighter then check the wires going to the inverter. one controls the brightness adjustment.

No display it is power is on


Hook up to external monitor .. Does the pre boot screen pop up (black and white writing at start ) ? If display runs on external monitor then your screen needs replacing usually or if you see a vague image on laptop screen then inverter or backlight is gone .. if no display on external and no pre boot screen probably the graphics chip on laptop has malfunctioned.

Dark Screen


there is a weird possibility that somehow your PC is configured to save power.. that is something you can do on a laptop to save battery..
you can check in the control panel what is the status of your energy options and see whats going up there..
there is also another possibility that it might be the monitor to be malfunctioning... but if after the screen being dark and you enter the options on the monitor and they are bright i doubt its a malfunctioning monitor..
so try to reinstall the monitor drivers and possibly the drivers of your video card if you have one.. but my biggest bet would be the option energy in the control panel

When I connect my ASUS monitor to my Dell laptop the ASUS monitor displays nothing instead it says "No Signal"


Hi

You do not say if your laptop screen is working or not or why you want to use an external monitor.

Assuming the laptop has no fault and boots properly, to send the laptop image to an external monitor, once you have booted into Windows, press and hold the Fn (function) key bottom left of your keyboard, near the Windows Logo key, then simultaneouly press the Function key (above the numbers) with the image of 2 monitors, 1 dark, 1 bright (often the F4, F5 or F6 key).

If the laptop's screen is faulty and the above procedure does not work, there may be damage to the graphics card which will probably require specialist repair.

I hope this helps.

I have 2 gateway t series laptops..... they both have a black sreen ...have to use external moniters


If you are able to use an external monitor then the video card in the laptop is working perfectly. The monitors built in however have failed. The most common situation is that the lamps burnt out, but it is possible that the wire that connects to the main board has been damaged from opening and closing the lid.
You could search the internet for a replacement monitor, but I would recommend one that has the casing and everything. It is extremely troublesome to remove the casing and change out just the panel.
Often you can find an identical model laptop on ebay that has a working monitor but other component failure and then you can either swap your components or just the monitors, whichever is easiest.

I have a Gateway laptop whose screen just broken and is cracked. However, I also do have an external Gateway monitor, model NO: FPD1730. I hooked up the external monitor to the laptop and it only works in...


Excuse me if I'm talking below you level of expertise...

With an external monitor on a laptop you usually have to activate the plug where you've connected the external monitor cable . This requires pressing 2 keys in combination, usually a FUNCTION button + a specific function key. Yeah, they're named almost the same thing, but I'll try to keep it straight.

On your keyboard's function keys (above the numeric keys typically) should be small pictures besides the standard F1, F2, etc. which are usually in white. You're looking for the picture that resembles a monitor. On my Thinkpad the small pictures are colored blue, and the monitor is on the F7 key. It so happens that my FUNCTION button (different than the function keys we were just talking about) which is located in the lower left of my keyboard is also blue. Yours might be in a different position, but I'm giving you an idea when to look.

When you find the Function Button, press and hold this key and the correct Function key (F1, F2, whatever). You might need to press this 1 or 2 times to get the correct monitor setting. I'm not exactly sure of the order but you'll activate the external monitor, then another combination press will activate both displays, then a 3rd will do another setting, then back to the beginning. If you miss it the first time just slowly press the combination until you get what you're looking for. Be patient, and press once every 5 seconds or so, giving the computer enough time to change its settings.

Hope this helps!

Free drivers


Hi,

To my knowledge, most monitors would work with or without a driver. In your laptop pls press Fn + F? keys to activate the external monitor. Pressing on both combination would cycle on the choices of laptop display only, laptop + external monitor displays or external monitor only. The F? key would be specific to the brand and model of the laptop and would normally be with an icon monitor.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Monitor too dark....


Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life.
First thing to check would be just that.
