Living life in 4k

Has anyone had any really great success running dual 4k monitors? Seems i get some sluggishness around my test machines.

Running a VMWare shop.

Not sure if its the monitor or the zero client or just the cards themselves cant handle. Running a P4.

If you have had success i would be interested in hearing what you are using.

For sure the P4 is capable to run more than 2x4K. You should look at the remoting protocol and test with a fat client first to see if it is endpoint related.
