I have a Thinkpad X230. I'm trying to drive video to a Samsung LCD TV via the mini displayport,
with a mini displayport --> hdmi adaptor (i've tried two adaptors now).
The X230 detects the the Samsung TV when connected, both in the Sound and in the Graphics Properties. You can hear the connect / see the PC screen flash when the cable is plugged in. Unfortunately I can't get any sound or video on the TV. (I just tried connecting to a Dell Monitor and was able to get it to work.) The TV takes HDMI from my Dell laptop just fine on the same cable/input to the TV.
The other problem is that in trying to adjust settings, now when I plug in the HDMI cable via the adaptor, the PC screen goes blank, it seems to be trying to make the TV primary, and the TV is getting the signal, so I have to pull the cable out to get the PC display back.
Any ideas on setting / adjustments?

Welcome to Lenovo Community!
Can you check uninstalling the current graphic driver from Control panel -- Program & feature option, and download the latest version from the below link.
Hope this helps.

Even my next step was to check with the connectors (Converter adapter), I am glad to hear that your issue has been resolved after replacing with new adapter & cable.
Please feel free to post in Lenovo Community Forums if you have any further queries!

I download the driver link you attach and upgrade the Intel HD Graphics 4000 driver to v 22.214.171.12459.
However, my X230 mini displayport still have the problem can not detect the HDMI at Samsung TV HDMI interface.
I use the cable mini displayport --> HDMI
But if I use cable mini displayport--> D-Sub(VGA) on LG LED monitor , it did works.
May I know how to solve this problem? HELP!!

I had purchased "Gold Plated Premium Mini DisplayPort (or Thunderbolt) to HDMI Male to Male Cable, Black 6 ft" from Amazon for my Lenovo Thinkpad x230. However it not work. I connected the miniDisplay port to Lenovo x230 and HDMI to Sony Bravia LED TV, Chose HDMI option from LED TV, but there was no detection on any signal at all in the TV. I also did the following "Go to -> Control Panel -> Appearance and Personalization -> Display -> Screen Resolution". There is no TV detected there. Pls suggest what needs to be done. My LED TV HDMI ports are fine as I hooked up the DVD and it works well. I also have updated the Lenovo drivers for Intel HD Graphics Driver for Windows 7 (64-bit)

Don't buy the "Gold Plated Premium Mini DisplayPort (or Thunderbolt) to HDMI Male to Male Cable, Black 6 ft" from Amazon (http://www.amazon.com/Cable-Matters%C2%AE-DisplayPort-Thunderbolt-Compatible/dp/B00EHTUSMU/ref=sr_1_...) it DOESN'T WORK. I bought it and had to return it because my TV (Vizio SmartTV) wasn't getting a signal. Instead I went to BestBuy and bought the Insginia Mini DisplayPort to HDMI Adapater and a Insignia 6' HDMI cable. Got home and it worked perfectly!
