The LCD panel is a 42” color TFT active matrix wide LCD with a display area of 36.6” horizontal x 20.6” vertical with a 42” diagonal viewing area. The panel’s native resolution is 1366x768 and it boasts a fantastic 1200:1 contrast ratio. Viewing angles are great at 178 degrees both horizontally and vertically. Just like with PC gaming LCD monitors, the gray-to-gray response time matters on a TV and the Viewsonic N4251w 42” LCD HDTV has a good time of 8ms.
Typical brightness of the TV is 500 cd/m2. The TVs light source is good for 50,000 hours. Viewsonic went all out on connectivity with the N4251w 42” LCD HDTV giving it three HDMI connectors that support HDCP which is fantastic. Those not using HDMI will be glad to hear that you also get coax, composite RCA, component HD and S-Video connectors as well. A 3.5 mm mini stereo audio in/out also allows you to use headphones or connect your PC sound output to the TV speakers. You also get an SPDIF out for digital audio.
|Input & Output Options on the Viewsonic N4251w 42” LCD HDTV|
A 15-pin D-sub is provided to allow you to connect your PC via analog connections and the TV can do resolutions of 1024x768, 1280x768, 1280x1024, and 1280x720 for PC in addition to the native resolution of 1360x768. You can also connect your Mac to the Viewsonic N4251w 42” LCD HDTV as well. The tuner used in the Viewsonic N4251w 42” LCD HDTV is ATSC/NTSC. Size the Viewsonic N4251w 42” LCD HDTV comes in at 40.4” x 30.4” x 11.6” with the stand and weighs 73.3 lbs net with the stand. TV/Video resolutions supported are 480i, 480p, 720p and 1080i. The sound system uses two speakers that a 10-watt designs and support Dolby Digital surround sound.
For testing I connected the Viewsonic N4251w 42” LCD HDTV to a Denon S-301 home theater and Sudden Link HD Cable via HDMI. The 1200:1 contrast ratio gives on screen images nice deep blacks and makes for good transitions form light to dark. Problems here often show up in the form of pixilation in scenes with lots of dark and light colors, especially at the transition between the two. I noticed none of this with the Viewsonic N4251w 42” LCD HDTV.
HD programming at 1080i looked fantastic and the TV automatically changes the screen format during HD programming if a commercial comes on that isn’t HD so the image doesn’t look stretched or pinched which is nice. Colors are reproduced very realistically and skin tones look great and natural. Overall the image quality on the Viewsonic N4251w 42” LCD HDTV is absolutely top notch. The fast 8ms gtg response time means that there is no ghosting during video playback, TV or gaming with consoles or PC.
The built in sound on the Viewsonic N4251w 42” LCD HDTV is of good quality and you can adjust the bass and treble within the menu settings. I used the SPDIF out to my receiver to enjoy Dolby Digital Surround Sound. The remote is well laid out and easy to use and can be used as a universal remote for your other AV components if you desire. Changing inputs on the TV is easy to do, you simply hit the source button and a list of the TVs inputs comes up and you choose the correct one for your needs. The only thing really missing here are front panel inputs and I think most of us will never miss those.
