No hdmi output from Asus EAH5450.

There should not be a driver required for this. As long as your HP desktop has a VGA video or HDMI video output, you can connect to the back panel of the TV from the video port of the PC. Then, on the remote, select the "PC" option for VGA input, or HDMI for the HDMI 1 or 2 input(s). If the PC only has DVI output, then it is important to know if the output is analog or digital. If it is digital (DVI-D or DVI-DD] then there is no available port on the TV to support it. Using a DVI-VGA adapter on a DVI digital output will not work as there must be a digital-to-analog conversion in order to work.

It will depend on the laptop's available external video ports. You can connect a VGA cable from some laptops to the VGA port on the TV. Then plug in a 3.5 mm audio cable from the headphone jack to the PC audio in port. (The audio connection is optional. You could continue using the laptop's speakers.)

Make the connections with the TV and the laptop off. You may need to enter the BIOS to enable the external video port. (It can be turned off to save power. The BIOS is accessed on boot by pressing a key (Esc, F1, Del) noted on the splash screen. For Win8 machines, you'll need to do a special restart.) Then turn on the TV before turning on the computer. The TV monitor should be automatically recognized for resolution and refresh rate. Next, if you have a Windows system, right click on the desktop (pick a spot with no icons or running programs). Click on Screen Resolution (or perhaps Graphics Properties, depending on the OS). Set the monitor to duplicate the screens or send data only to the TV screen.

I'm not sure if the HDMI ports will understand a computer signal. (Not all TVs can interpret the computer's HDMI signal; it is different than that of other set top boxes.) You can try the following connections.
If your laptop has a DVI output, use a DVI to HDMI cable (or adapter) to connect to the TV. Then connect the HDMI cable to HDMI 1 and use the PC audio connection as above.
For an HDMI output, use an HDMI cable. (You will still need the audio cable unless you can reset the audio signal to output on the HDMI port. Go to the Control Panel and then the Hardware and Sounds section. Under Sound, select Manage audio devices. Then in the Playback tab, make the HDMI audio the default.) For Display Port or Thunderbolt outputs on the laptop, you will need a DP to HDMI adapter.

If the HDMI port doesn't understand the computer signal, you'll need to use a converter to go from the computer's output to component video or to VGA. Then connect the converter's output to the appropriate port on the TV.

I hope this helps.

(To access the Control Panel in Windows 7 and earlier versions, click Start and then find the Control Panel in the right hand column. For Windows 8, press the Windows key + X (or access the Charms menu on the right-hand side (Win+C) and choose Settings). Then select the Control Panel.)

Hi Jatinder Kumar ,
Yes you can connect your computer output to lcd tv through dvi-hdmi cable or vga-hdmi cable.
1. Connect to HDMI (DVI) : just plug in HDMI (DVI) out of PC or laptop to HDMI or DVI TV. Than select source from HDMI.
2. Connect to PC : Plug D sub to TV, select PC in.

I hope that will help you.
thanks.

The VGA cable is strictly just for video so the sound is received thru an analogue (RCA) cable. HDMI is an combined digital link but the video card delivers only the video - you must tell the tv from where to get the sound (use the analogue connection already in place) This is done in the menu.

Unless the tv has a VGA input, or the laptop has a HDMI output, I am afraid you are going through too many conversions to make this work.

Why do you use VGA-HDMI cable? This TV works fine with VGA cable - it has VGA plug.
Or if your notebook has DVI output, then you can use DVI/HDMI cable and connect it to the TV to plug named DVI/HDMI (only one HDMI input is marked as DVI on TV).
I suppose that over HDMI the TV supports only some standard resolutions, but over VGA it supports almost every resolution laptops use. You can find supported resolutions for each input in the TV manual. Try setting the same resolution on the laptop.

It will depend on your video output options on the computer. If you have HDMI output, just use an HDMI cable and an audio cable (this will need to be a 3.5 mm to RCA audio cable). If you have a DVI output, use a DVI to HDMI cable and the audio cable (or a DVI to HDMI adapter and either a DVI or HDMI cable depending on which side you want to put the adapter). If you only have VGA out from the computer, use a VGA to DVI adapter and the DVI to HDMI connection and the audio connection. (Theoretically this should work but each adapter will have some signal loss issues.)

Some graphics cards have a video output, S-video or Component video, which would also connect to your TV with the audio cable. (Read your cards manual for more information)

I hope this helps.

(For DVI to HDMI cables, you will need to check if you have a single link or dual link DVI output. The wrong cable may not work.)

the Flat Screen TV if has, a HDMI input, also has VGA Input.

You must choose :HDMI or VGA, if HDMI The VGA board must Have HDMI Connector, and you connect a HDMI cable to the TV.

The HDMI is a digital signal input/output, VGA is Analog Signal. You must have Signal Converter if you Use the 2 signals

dvi to hdmi cable

what model of TV was it please,
Does your computer have tv out video card installed?
For video to tv you will need a vga to tv converter,this is an external device and will work on the computers vga output straight into a vga input and give you 1 x vga out,1 x rca out, 1 x s/video out,comes supplied all prebuilt with onboard graphics solution. no extra power required runs straight of vga output.
Once the computers video output is established then set the TV up to tune into the converters output signal.
HD TV can be set up to run thru rca and components and if model is late enough shuld come equip with serial vga input for computers.Other than that HDMI seems to be the better quality of picture over rca component.Cost verses dollar really and function.
