1080p is absolutely the best for computer monitor display. As far as brand, I use an LG 32" 1080p that I bought last year. Best I have ever used, either as a monitor or a TV. Amazing color saturation, smooth transition and picture. As far as size, you don't want to go too big, otherwise your display will be grainy. 32" works great for me. That's my suggestion. I use it quite a bit as a monitor and very impressed. Hope it helps!

How do I use a jump drive to display a power point presentation on my TV?

It means it is only for putting new firmware onto the tv. You won't be able to load anything through this USB port. The TV is looking for a specific filename to run and even if you named your powerpoint presentation the right name, the TV will not be able to display it.
Your next best option is to get a DVD player that has a USB port for MEDIA and load a slideshow of IMAGES. You'll have to export your PowerPoint as images first (obviously).

My acer laptop screen has broke and i would like to know if its possible to connect it up to my 42" samsung plasma ?

Most laptops have a 15pin D-sub connection that allows you to attach an external display. Most LCD and plasma TV's also have a 15pin D-sub connector to connect a PC to.

Look on the side of your laptop and the back of your TV for this connector and if both have it just find a standard monitor cable to connect them.

Your laptop will have a function key to enable or disable the external display.

My 32inch lcd tv keeps flickering it started all the sudden


    • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
    • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
    • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.

Screen blank

Post the manufacturer and model number of the laptop. Model number is located on the bottom of the computer. In the meantime I can only give you a generic diagnosis to follow;

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.

This is an example of a VGA Cable, and VGA connector, (Port),

(On the laptop near the VGA port it may have RGB, or External VGA, or nothing )

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable attached.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external VGA monitor.

IF not; Hold down on the Fn key, and at the same time tap once on the Display Toggle-Over key.

The Display Toggle-Over key will be one of the F keys at the top of the keyboard. (F1 through F12)
HP laptops for example, usually use the F4 key.

After performing the above, there is no display on the external VGA monitor;

There are at least 3 display options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

NO display shows on the external VGA monitor?
You have a bad graphics chipset, or the mounting of it to the motherboard is bad.

Display shows on external VGA monitor?
You have a problem with the Video Cable, or in the Display Assembly itself.

A) Video Cable:
This cable connects to the motherboard, under the Keyboard area, or just above it.
It then goes along, and up under the left Hinge.

From there it goes up into the Display Assembly, and connects to the back of the LCD screen.
There is also another wire, or two, that comes from the Video Cable, and connects to the screen Inverter


An LCD screen does not produce light by itself. It needs an additional light source. A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), or a series of LED lights.
(These two technologies are used in the present )

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[ Average size is 2mm Thick, and the length is almost as long as the LCD screen is in height.

2mm is a little larger than 1/16th of an Inch.
More information on CCFL, and general guide to replacing, ]

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.

90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.

Some average examples of a screen Inverter used in a laptop,

The thin plastic 'frame' in front of the LCD screen, is a Display Bezel. Has many names, depends on the manufacturer.

The screen Inverter is located behind the Display Bezel, and mounted at the bottom of the LCD screen. (Usually)

Primer over.

Check the video cable connection on the motherboard side, and at the back of the LCD screen.

Just with opening, and closing the laptop, the video cable could have been pinched in the Hinge.
This would lead to the video cable being pulled on, and pulling a connection loose. (Or both connections)

It could also lead to damage of the video cable.
Check the cable's outside sheath for obvious signs of damage.
This may indicate damage to the tiny wires inside.

It is best to completely remove the video cable, and with a multimeter check the wires inside for continuity. (Set the Function knob to Ohms)

B) Display Assembly:

The Display Assembly consists of the;
1) Display Bezel
2) Display Cover. (Top cover of laptop over LCD screen )
3) LCD screen
4) Hinge brackets, and Hinges
5) screen Inverter
6) Backlighting
7) Web camera (IF installed)
8) Microphone (IF installed in Display Assembly )
9) Screen Frame (Holds the LCD screen assembly together )

If the Video Cable checks out OK, move on to the screen Inverter.
Look to see if the cable (Wires) connections to the screen Inverter are tight.
Physically check, do not assume by just looking.

Is there any obvious signs of damage to the screen Inverter?

To test a screen Inverter requires a sensitive multimeter. Read fairly expensive,

Due to the fact;
1) That most do not have a multimeter of this type around,
2) The ease of accessing to replace a screen Inverter,
3) The usually low cost of the screen Inverter,

, the screen Inverter is replaced. Parts changing I know, but you have to use what is available to you.

Replaced screen Inverter, and you still have no display on the laptop's internal monitor?
Replace the LCD screen.

If a laptop uses CCFL for Backlighting, there is going to be a screen Inverter.
If a laptop uses a series of LED lights for a Backlight, there MAY, or MAY NOT be a screen Inverter.

In this case the LCD screen itself is replaced.

If you post the laptop manufacturer, and Model Number, (In a Comment), I may be able to link you a Service Manual. Also there may be pictorials with disassembly information.

Guide you as if I was sitting next to you.

The laptop comes on but no pitchure on the screen

1) Use a flashlight, and shine it at the LCD screen of the Acer laptop at various angles.
Do you see faint images?

2) Laptop off you can also attach a VGA monitor (CRT. Looks like a small TV), to the VGA connector on the back of the laptop. Laptop on, press, and hold down on the Fn key, and press the Function key which toggles the graphics over to an external monitor. (Usually there is a icon on the key for this, on the keyboard)

Graphics present on external monitor?

If so you have a problem with the Inverter. (Screen Inverter)

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Much like the Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
(Average Backlight size is half the thickness of a No.2 pencil, and 3 to 4 inches long)

An Inverter is used to convert the electricity coming from the laptop for the LCD screen, and the Backlight.

90 Percent of the time the fault is the Inverter.

The Inverter is located inside the Display Assembly.
[Display Assembly:
1) Top cover of laptop.

2) Display Bezel in the front of the LCD screen, and surrounds the outer front edge of the LCD screen. {Looks like a picture frame}

3) LCD screen

4) Web camera if this model has one.

5) Wireless Antenna

6) Inverter

7) Backlight

8) LCD screen metal frame, and hinges

9) Various screws ]

With the Display bezel removed the Inverter is located at the bottom middle, below the LCD screen.

{If I knew the Model Name, and Model Number of your Acer laptop I MAY be able to post a link to a free Service Manual for it}

If no faint images are seen, and/or an external monitor shows no graphics, there is a problem with the graphics chip on the motherboard.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The graphics chip is mounted to the laptop motherboard via a BGA surface mount.

BGA surface mount:
To explain let me compare the older style of mounting Processors.

The older Processors have pins sticking out of the bottom. These pins lined up with socket holes in the Processor socket.

The Ball Grid Array type of surface mount has no pins on the chip. (In this case a graphics chip)
There are solder balls in place of the pins.

The area where the chip mounts to on the motherboard has copper pads.
The chip is lined up with the solder balls matching the copper pads.
Then heat is applied which melts the solder balls, and solders the chip to the copper pads.

If there is a poor cooling system for the graphics chip, the chip overheats, and the BGA surface mount becomes loosened.
The solder connections melt partially.
This creates a poor contact surface for the graphics chip to the motherboard, resulting in no graphics being shown on the LCD screen.

I await your findings with the flashlight, and/or external monitor. Would also like the Model Name, and Model Number. (Bottom of laptop)

What model laptop do you have? Specifically, does it have HDMI? What video card does it have?

If you'll be driving it by VGA then the main thing is to get a TV that supports 1080p over VGA - not a real big deal now. If you have HDMI then it's even easier as any decent TV today will have HDMI.

Be sure to get a model with VESA holes on the back as these will be needed for the wall mount hardware to work.

When it comes to brands, you won't go wrong with Sony or Samsung but you'll probably pay a small premium. Obviously, the larger the TV the better the picture. 37" is probably the minimum size to consider.

When you are picking a TV don't forget that the most important thing is how you think it looks subjectively. You should also not forget to check the usable viewing angle relative to the space where it will be mounted and where the viewers will sit; you won't be happy if the people at the end of the conference table see nothing more than a shaded gray image.

Connecting laptop to TV

Depending on the brand of laptop, there should be a hotkey (Key combination) that you press to activate a presentation mode.
On my Dell it's Fn (Function) + F8.

Also, you have to have your TV set to the Video or AUX mode that the s-video cable is hooked up to. (Like AUX1/Aux2, or Video1/Video 2) Your best bet is to cycle through them slowly once you activate the presentation mode on your computer, or identify it by the markings near it on the back of the TV.

Sometimes I have to hit the hotkey a few times until my computer and TV 'like' each other.

If this doesn't help, comment on the solution post and we can try more ideas. :)

Hope this helps!

Show Microsoft Power point on Sharp Aquos hdtv

try to right click the desktop and choose graphics options, you will have to select the correct output for your setup. i.e. laptop to monitor, etc etc see if that works,...sounds like you have a connection, you will have to play with these settings until it pops up. worked with a similar scenario, sometimes you have to do stufff twice and it works on the second time not the first, electronics are weird.
keep changing the settings in the graphics options until it comes up the way you want it.
