Depends on where your computer is in relation to the TV.
For mine, it is in a different room, but I can see it if I keep the door open.
I use the Lenovo Enhanced Multimedia Remote with backlit keyboard. It sells for $75, which is WAY too expensive. Look online and you can find coupon codes. I got mine for $30 which is almost the same price as the one without backlit capability.
For me it works great. It allows me to use my desktop in another room (about 15ft away) with no issues.
EDIT: It works off of a small USB dongle. It is about the size of a penny.http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?GroupID=38&Code=57Y6678
