Re: I appear to be a vidiot

Sergei,

I think you're right about the HDMI cable. I found this on the Lenovo site:
http://shop.lenovo.com/us/en/itemdetails/0B47395/460/D60A78A4A48A422E9761BD184AD3750A

It's a Display Port to HDMI adapter. The advert states that "The
DisplayPort to HDMI Adapter is compliant with the DisplayPort standard and
has a bandwidth of 2.25 Gbps to support crystal clear 1920 x 1200 at 60 Hz
display resolution."

It would appear if I want to lose the fuzzy fonts and access the optimal
resolution on my LED I'll have to buy more parts.

Thanks for your help.
