Are there other comparably priced monitors that I should be looking at? It seems that the Dell has some response time issues.. which has better color fidelity?
I just got an NEC 2470WNX (S-PVA) last night. Its comparable to both (24" *VAs), with the exceptions being the Dell is wider gamut (HC) and the ViewSonic is an S-MVA. After extensive research which included speaking to an NEC sales rep., comparing panel models and input lag tests at TFT Central, BeHardware, and PRAD, and reading every 2470 review I could find (PRAD, I4U, ConnectReviews, Trusted Reviews, MaximumPC) plus user reviews on HardOCP and NewEgg, here's what I concluded:
- Why I picked it over the ViewSonic: The NEC has a faster response time (6ms vs. 8ms) and less input lag (2 frames vs. 3 frames). According to PRAD, the 2470 has 2 frames at native and 3 at interpolated resolutions. Perception of lag is subjective, but this seems right on to me because at 1920x1200, I simply cannot notice ANY lag in games or on the desktop, even though I've been looking for it. But when I change resolutions with the monitor's internal scaler, it definitely becomes noticeable...still useable, but I can tell. Fortunately, PRAD was also right that if you use your video card's scaler instead of the NEC's, the lag does not increase when changing resolutions.
- Why I picked it over the Dell: While both are Samsung PVAs, the NEC does not use the same "special" panel as the Dell HC "high color" (LTM240CS01); this means that it does not have the wider gamut, but most importantly that it DOES NOT have the infamous inverse ghosting problem.
- Why I picked it over every other 24" VA: The NEC uses the newest revision (LTM240M2-L2) of the panel the original Dell 2407 (non-HC) used (LTM240M2). This means latest fixes with no banding, blurry text, etc., as reported on the original 2407 revisions.
Also, I made a table comparing its specs to every other 24" PVA and MVA I could find: Dell 2407, BenQ FP241W, LG L245/246, ViewSonic VX2435, Samsung 245T, HP LP2465, Planar PX2411W, and even Westinghouse L2410NM. Results:
1. NEC 2470, BenQ, LG, ViewSonic, and HP have the highest brightness (500 cd/m2).
2. They all have the same contrast ratio (1000:1), which is relatively accurate as they are all VAs.
3. The NEC 2470, Dell, BenQ, Samsung, HP, and Planar have the fastest response time (6ms G2G/16ms). The others are 8ms/16ms, except for the ViewSonic which is 8ms/20ms.
4. The NEC 2470, BenQ, and LG have the lowest reported input lag for a 24" non-TN: about 33ms=2 frames. The ViewSonic and HP av. 40-50ms, and the Samsung av. 50+ms. Numbers came from XTKnight, HardOCP, BeHardware, and PRAD.
5. They all have the same "VA" viewing angles (176/178 degrees). NEC 2470 and ViewSonic 2435 list an honest 176, the others 178; but I'd say 176 is more accurate for a VA in comparison with IPS panels, assuming IPS are the best (178).
Results: NEC 2470 has the highest brightness and contrast ratio, and fastest response time with the least input lag, in its class. I therefore concluded that the NEC 2470 is the best 24" non-TN available, except of course the NEC 2490 (H-IPS), which is the best 24" made but is out of my price range.
