Well, I don't have a LCD monitor. I'll just tell you what I'm using
I have a Syntax Olevia 30" HD ready LCD TV. I bought it on Black Friday, and paid Micro Center $799US for it after mail-in rebate.
I have it hooked via DVI-to-DVI to a Windows XP Media Center Edtion box that includes:
Ahanix Devine D4 case
Asus K8N
Athlon 64 3000+
1 GB generic DDR
ATI HDTV Wonder
Hauppauge WinTV PVR-250MCE
Samsung 16x Dual DVD burner
ATI Radeon 9800 Pro
2x Western Digital 200 GB SATA
Belkin 1394 PCI card
Linksys 54G Wireless USB NIC
Connected to the Olevia: (1) WMCE box via DVI; (2) XBox via XBox special HD component cable to Olevia YPrPb; (3) Sony VCR via composite; (4) DirecTV STB via svideo; and (5) roof antenna via cable to dual analog tuner in the Olevia.
WMCE allows for TiVo like use: TV programs recording to hard drive, and time shifting with live TV.
The ATI HDTV Wonder brings in brilliant local HDTV. The HDTV Wonder dongle with svideo and composite connections allows for recording from VCR tapes or TV. The Hauppauge has FM radio as well as SD analog TV.
I have a Netflix DVD movie rental, and can watch DVD movies with XBox, Windows XP, or WMCE environment. DVD movies can be ripped to hard drive, and viewed from there in WMCE or from Windows XP with Windows Media Player 10, MPlayer, or any other player.
All recorded media can be burned to DVD or CD.
I currently play HalfLife2, Doom3, Far Cry, and Call of Duty, all are fantastic on the 30" screen. Only HalfLife2 and Far Cry provide widescreen resolution at 16:9 aspect ratio.
It's a different kind of computing.
