We usually save our weekly bargains for Fridays, but this one is too good to pass up. Until tomorrow at midnight, Pacific time, Newegg is selling a 23.8" IPS monitor from Asus for only $154.99—or $134.99 if you're willing to put up with a $20 mail-in rebate.
The monitor in question is the VN248H-P, a "super narrow bezel" specimen featuring a 23.8" IPS panel with a 1920x1080 resolution, 5-ms gray-to-gray response, 178° viewing angles, and 250 cd/m² luminosity. Asus outfits this display with one VGA and two HDMI inputs, VESA mounting holes, and 2W stereo speakers (which, if my experience with display speakers is any indication, you'll probably want to leave unplugged). And the thing is covered under a three-year warranty.
To take advantage of the deal, head on to the product page, add the monitor to your shopping cart, and enter the promo code "EMCYTZG45" at checkout. You'll also want to redeem the $20 mail-in rebate by following the instructions in this PDF.
