Subjective Evaluation
As usual, we spent some time using the display both before and after calibration. Many users don't have access to color calibration tools, while for imaging professionals some form of hardware calibration is standard procedure. We will start with our subjective evaluation before getting to the actual quantitative results.
After our last review, we actually heard from a reader who said he was a big fan of glossy LCDs. We actually preferred non-reflective finishes on our LCD panels, so we prefer displays like the Samsung 245T to glossy options like the HP w2408 -- and that's before we take into account other performance aspects. Hopefully, we've made it clear that we are not fans of TN LCDs, and switching from the HP w2408 to the Samsung 245T once again reinforces that opinion. With the two LCDs sitting next to each other, besides the better viewing angles on the 245T we also felt that it had better overall color quality and vibrancy. Some might prefer the industrial design of the HP display, but in all other areas we would rate the Samsung 245T higher.
Comparing the 245T to other LCDs that we've reviewed, the differences are not as dramatic. The Gateway FPD2485W and Dell 2407WFB are both quite similar in features and functionality, and to the naked eye we would be hard-pressed to tell the difference between any of these three LCDs. That should come as no surprise, however, since all three LCDs appear to use Samsung S-PVA panels. Pricing is also similar on all three offerings, although the FPD2485W has been discontinued and the 2407WFP is due for replacement in the near future. (Yes, we will be reviewing the replacement as soon as the NDA expires.) The major difference would be the inclusion of an HDMI port on the Samsung, or the flash media ports on the Dell LCD.
We did test out the other extra features that the Samsung 245T advertises, specifically the MPA (Motion Picture Acceleration) and the dynamic contrast setting. The difference between enabling and disabling MPA is quite small, but to our eyes the display did look a bit better with the function enabled. Except where otherwise noted, we left MPA on for the rest of our testing. The dynamic contrast did not make as good of an impression; as we will see in a moment, contrast ratios are indeed higher, but it comes primarily from increased maximum brightness and lower color fidelity. When you enable Dynamic CR, you also lose control over the color levels, contrast, and brightness -- all of these apparently get set to "automatic". So score one for faster response times, but forget about dynamic contrast ratios.
One other question that has come up is whether there is any sort of internal image lag - i.e. processing that can add a frame or two delay to the output. This is something that exists to varying degrees on all LCDs, but for the most part it's not an issue. There may be a 0.02s lag, but the vast majority of users won't notice it. During testing, we didn't feel that the 245T was any different than other LCDs we've used, but then we've never complained about input lag on any LCD we've tested. Considering double-buffering and SLI/CrossFire also add a couple frames of delay, and no one appears concerned about that, we're not too worried about LCD input lag. If we do notice it on future reviews, though, we will be sure to make a note of it.
Unless otherwise noted, we ran the remaining tests after calibrating the displays using Monaco Optix XR, both the professional version of the software as well as an XR (DTP-94) colorimeter. In some of the tests, calibration can have a dramatic impact on the result, but viewing angles and response times remain largely unchanged. We also performed testing with ColorEyes Display Pro, although the overall results were better using Monaco Optix XR.

I thought Samsung monitors had a 16:9 scaling mode?JarredWalton - Thursday, February 7, 2008 - link
This one doesn't... other Samsung displays might. See the OSD image gallery for details. The only options are "Wide" (fill the whole screen) and "4:3". That means that 5:4 resolutions (1280x1024) will also be distorted no matter what you do. I don't think the minor stretch of 16:9 to 16:10 is terrible, but some people care more about that than I do. Again, though, this is only an issue on non-PC use (or if your drivers don't allow you to correct the scaling).hotdogandchips - Thursday, February 7, 2008 - link
Jarred, can you tell us when the NDA regarding the 2408WFP expires by any chance? ;0JarredWalton - Thursday, February 7, 2008 - link
LOL... actually, no, I can't. Funny thing is that the date isn't set in stone just yet either, which is part of the reason I can't say. It's supposed to be this month, based on what I heard at CES, but it might get moved to early March?AcAuroRa - Thursday, February 7, 2008 - link
According tohttp://www.samsung.com/us/system/consumer/product/...">http://www.samsung.com/us/system/consum.../C070096...
... its a TN.... bah I'm confused -_-.. is it a TN or a PVA?
I actually own a w2408... and I actually like the thing -_-;;...but if there can be some facts straightened out I might go and get a 245T off the 'Egg as it is currently on sale for $650...

See above post... the unit I reviewed is most assuredly an S-PVA panel. I believe the PDF is simply erroneous.bobo51 - Thursday, February 7, 2008 - link
I am confused.The article identifies the 245T as having a PVA panel. But I just went to the Samsung website and in their specification PDF for the 245T the panel is stated to be a TN.
Is their website document incorrect?
JarredWalton - Thursday, February 7, 2008 - link
I can absolutely state that the 245T LCD I have is S-PVA (based on how it looks from various angles), and Samsung told me it was S-PVA before I received it. http://www.samsung.com/us/system/consumer/product/...">This states otherwise, so I guess someone just put the wrong information in there. The other possibility is that there are different LCD panels in some of the 245T displays... hopefully not.Most companies do not make a point of stating what sort of technology their panels use. While I can understand that on TN panels, I'd think anyone using a PVA or IPS panel would want to crow about it. Kudos to Samsung for at least putting information on all of their displays in the PDF files; now they just need to make sure the data is correct. :)
I'm going to email my Samsung contact about this and see if there's just an error in the PDF that they can correct.

I was all excited about this new display until I read about the limited scaling choices. I can't believe they didn't include a 1:1 or pixel to pixel option! Not everyone has a triple SLI video card setup that can run Crysis well at 1920 x 1200. I'd much prefer to run the game at a lower resolution with black borders and have the "pixels" look sharp, as opposed to stretching the non native resolution to fill the screen and look blurry! Plus automatically stretching 16:9 aspect sources vertically to fill the 16:10 screen is just plain ludicrous. Most people can notice when the aspect ratio is displayed incorrectly. What happens with a 2.35:1 ratio DVD? Does that also get stretched vertically so that you dont' see any black bars at the top or bottom? This single design flaw is a definite deal breaker for me. I hope the upcoming new models from Dell, etc. don't have this same design flaw.yyrkoon - Friday, February 8, 2008 - link
The big question would be; 'why do you need a 24" LCD to play Crysis?' For me personally I cannot see the need for anything much more than a 19" LCD(a good one at that) for gaming. This making current title fly on my C2D system with a 7600GT, and it draws way less power than one of the current higher end cards. Granted I probably wouldnt mind using a 8600 or something that draws slightly more power, and has DirectX 10 capabilities, but I wont go out of my way just yet to purchase another card, especially since I am still using XP Pro.Also I'm noticing complaints about input lag ? I would think this would be an image retouching LCD which doesnt require fast screen refreshes. You can buy cheap fast LCDs that will play games just fine(all day long).
