The provided HDMI female receptacle is being used by the DirecTV hookup. Is there an adapter, from coaxial cable to HDMI (male receptacle)?

You may need a different cable or gadget but you did not specify an exact model. You may be able to use vga and separate audio out to a TV or s-video

Not sure due to lack of information to go on
I. think you need a tv coaxial female to f plug male adapter
really depends on the TV cable cord what is the gender of the end of the cable if it is coaxial male then the adapter needs a female coxial
if the tv has a female socket hole then the f type part of adapter needs to be a male.

The tv manual may shed some more info on the type of RF antenna coaxial connector. it uses.
RCA can be confused as av is to do with with hooking up a Video recorder with Video output being the yellow plug and audio with Red and white plugs.

I think you need a RF coaxial adapter rather than AV RCA if you are connecting tv to a tv antenna or tv antenna splitter device.
there is a RCA standard that has adapter like below link http://www.radioparts.com.au/product/30255099/pa5099-%27f%27-plug-to-rca-socket-adaptor#.VUa7uJM_xhI
again gender types are needed to be considered before deciding if correct type of adapter..
You could research the rca rf standard to see if it is used in your country. My country uses Pal coaxial standard.

.

You need an 1/8th inch male to two RCA male Y cable. the Y cable is only going to be 3 inches long so you will need to extend that with two cables to the length you want. For that you will need two RCA female barrels and two male to male cables at whatever length you want them to be. If you can solder you can make a cable without barrels.

Connection the monitor depends on the connections you have out of your Toshiba laptop.

The monitor has both VGA and DVI.

If the Toshiba has a VGA out, all you need is a VGA cable available online, computer or electronics store.

If the Toshiba has an HDMI out, you can connect it to the DVI on the monitor with an HDMI cable and an HDMI to DVI Adapter.

You can also use USB out with either a VGA converter or a DVI converter (go with DVI for the better picture). Converters can be found online at Amazon, you may also need a standard male to male DVI cable to use with the converter.

I assume you mean HDMI output. You'd need a 'HDMI Female to VGA Male' adapter or a 'HDMI Male to VGA Male' cable.

I've no idea if that site is reputable or not, just did a search on Google.

Yes ! all you have to do is go to radio shack and tell them you want a coaxil to RCA adapter (screw coaxial into wallplate and plug RCA end into sub and your all set!)

Thank You

All coaxial inputs or outputs on any unit is the screw-post type. The female part is a standard coaxial cable that slips onto the posts on the unit. Are you trying to convert Coaxial to RCA?

You are missing the Coaxial Adapter.

Visit www.samsungparts.com
At the search by dialog box at the top right, type SYNCM910MP
You should find 16 parts for your LCD monitor.
Click on 3705-001191 which is the 2nd part listed.

You can download the manual at www.samsung.com. Search 910mp and download the 20mb user manual for tips on setting up and troubleshooting. Good Luck.

Hi,

Most TV models/cable providers uses the F type of coaxial connector as shown below.
However, some versions intended for other regions (Europe & Middle East) uses the PAL type of connector likewise shown below.

If your model uses the latter and your cable provider uses the F type, what you need is a straight F type Female to PAL Male adapter. Or it could even be just the other way around.

They are available in most electronic parts/supply store or online. You can try here, here or here.

Hope that this be of idea/help. Pls post back how things turned up, r should you need additional information and/or if your cable connectors are of different types. A photo of the connectors would be nice.

Good luck and kind regards.
