Probably the drive is going bad. You can use an external DVD player/writer. It is affordable and it is available on eBay.com.

way beyond this old one ,TVs had only one channel in B/W when i was young

For the Toshiba Satellite C855D-S5105, HDMI is an option.

If present, believe it to be on the Left side, same as the VGA port.

[General example of VGA connector (Port), and VGA Cable,

Note* Color is not always Blue. Scroll down a little for VGA Cable example ]

User Manual states plug external monitor device into laptop, then turn external monitor device on.
External monitor device should automatically be seen by laptop.

If not press, and hold down on the Fn key, and at the same time, tap on the F4 key until the display option you want is shown. Then press the Enter key.

Touchscreen?
That requires a knowledge of Windows 8, which I do not have a full understanding of yet. The User Interface of Windows 8.

It isn't stated by Toshiba, (At least that I could find), as to if the HDMI port; is just that. An HDMI port, or a Mini-Port HDMI port,

There are HDMI adapters, and HDMI cables; that adapt from regular HDMI to Mini-Port HDMI.

There are adapters that connect to a VGA port, and convert to an HDMI port.

Hi Alex,
The Toshiba C855D-S5320 does. Can you confirm the type of C855D you have. With the description of the plate I doubt your model does. On the one I use, I knowingly gave up touch screen for HDMI with budget I had. I have it connected to a 24" ASUS screen and I'm very happy with HDMI. Good luck! Toshiba C855D S5320 Laptop

According to Toshiba Website - there is no HDMI port on this model laptop.
