Samsung 245T: LCD Prime

Calibrated Results
Brightness and Contrast Ratio

For those that need accurate colors, you really need hardware color calibration. Here, we report scores for the same areas as we did on the previous page, only this time we gather the results after we calibrate the display with Monaco Optix XR Pro.

Calibration is usually best at decreased brightness levels, and we found dropping the 245T from its default settings down to 30% brightness (and keeping the default 75% contrast) with RGB settings of 36/50/50 resulted in the best scores. (Note that the red by default seems to be brighter than necessary.) We test indoors with a moderate amount of lighting, and adjust the displays according to directions. The Samsung 245T ends up ranking as one of the best LCDs we've tested, post-calibration, with a score of 1.07. Nearly all of the scores are close to 1.0, and only one color as a Delta E above 2.0.



We also tested with ColorEyes Display Pro to see if we could achieve better results. So far, we have yet to encounter a desktop LCD that scores better using ColorEyes Display Pro, which is actually surprising to us -- it seems more robust in many areas and generates newer ICCv4 profiles, but the final reported scores continue to be lower on desktop displays.

While we cannot make any sort of guarantee that the color profiles we created are anywhere near representative of all 245T panels, we frequently get requests from readers for these color profiles. If you want truly accurate colors, your best bet is to go out and invest $300 in a colorimeter and software calibration package. If you're still interested in trying out our profiles, however, we are happy to make them available. Again, your mileage may (re: will!) vary.

    First, I'd like to thank Jarred Walton for his excellent review. A great deal of work goes into such a review. So, first and foremost, thank you sir! I'm also impressed by your timely follow-ups to the comments that have been posted.

    I just purchased the Samsung 245T (August, 2008). The firmware evidently has changed because there are new scaling options.

    I'm only using two inputs - the VGA for various computers connected to it via a KVM and a Sony Playstation via the HDMI.

    The VGA input now shows three options for size: wide, 16:9 (this is new), and 4:3. Wide is the only useful option (it appears to be 1:1 pixel mapping). The other two options distort the display. Why 16:9 was added as a choice is hard to say because it adds no useful function I can think of.

    However on the HDMI input (and perhaps the DVI - I didn't test the DVI input) we have the old choices - Wide, 16:9, 4:3 and a new one! The new one is called "Just Scan" which seems to be 1:1 pixel mapping. Samsung evidently is listening.

    I find it interesting that 4 months after Jarred was reassured by his contact at Samsung that this panel was a PVA, it is still speced as a TN panel on the Samsung website. And the mail order websites that report this characteristic seem to just parrot what is on the Samsung website.

    It would seem that it being a PVA unit would be a marketing point that Samsung would want to be front-and-center in their specs and advertising. So why isn't it out there?

    Does anyone have any written documentation or labeling on the back of a unit (or anything other than someone's statement) that this is a PVA panel?

    All of the 24" panels on the Samsung website state the same type. I'd like to know for sure.

    Just thought I'd point out that there's an error in this review regarding display modes. It's true that there's no 1:1 pixel-mapping, but there IS a 16:9 option, it just isn't available when using a DVI source (I'm guessing because Samsung figure DVI = PC only and video cards support 16:10 resolutions). For HDMI, component, S-video etc, the 16:9 option will keep your 1080p signal un-squished and 720p will be upscaled. Check it out for yourself in the user guide, about 2/3 of the way down the page- http://downloadcenter.samsung.com/content/EM/20070...">http://downloadcenter.samsung.com/conte.../200707/...

    The new Dell 2408WFP has been available for perhaps a month. When are we going to see a killer review on AnandTech?

    Conflicting Information!!!

    Page 4 of this trustedreview of the 245T states "genuine 1:1 pixel mapping"

    http://www.trustedreviews.com/displays/review/2007...">http://www.trustedreviews.com/displays/.../2007/11...

    ".....A tonne of connectivity only adds to the appeal, as does the genuine 1:1 pixel mapping from 1080p sources."

    This Anadtech review clearly states the opposite!

    Who is correct here? Clarification appreciated, as you've thrown a monkey wrench in my purchasing decision! :P

    Thanks

    found this:
    source: http://www.hardforum.com/showthread.php?p=10319083...">http://www.hardforum.com/showthread.php?p=10319083...

    According to the User's Manual:
    - if the video source is connected through PC/ DVI, you will be able to switch the size between "Wide" and "4:3";
    - if the video source is connected through Composite/ S-Video, you will be able to set the size to "Wide", "16:9", "Zoom1", "Zoom2" or "4:3";
    - if the video source is connected trough Component/ HDMI, you will then be able to choose the size between "Wide", "16:9" or "4:3".
    Supposedly, by "Wide", they mean "Full screen" (1920x1200).
    I don't really know what they mean by "Zoom1" and "Zoom2", but I guess this is some scale of "expansion" (by keeping the aspect ratio). But I insist, this is just me guessing; I do not own the screen.
    As matter of fact, this leads also to the conclusion that there is no pure "1:1 pixel mapping" for all resolutions, even if you can get such pixel map for a HD 1080 lines source if you choose the "16:9" size.

    can you confirm please, & perhaps update the review? many thanks.
  • JarredWalton - Saturday, February 16, 2008 - link

    I checked the VGA and DVI connections... I didn't consider that they would add options on other inputs (most OSD controls gray out disabled options rather than removing them completely). I'm trying to come up with some meaningful "input lag" testing -- internal image processing lag would be more appropriate as a description -- so I'll see about testing the Component/HDMI/S-Video as well.

    Not surprisingly, I've got other things to review as well, so it might be a couple weeks before I get around to testing this.

    thanks.

    looking forward to seeing the input lag & HDMI pixel mapping options on the 245T. :)

    word on the street is that the input lag is pretty bad, ~50ms, (2.5 frame lag.)

    from my readings, 50ms (while on the upper end of laggy displays) may still be usable for all but the most time-sensitive games. (fps specifically) a lot of people complain and overrate the input lag problems on forums, though it's evident few understand what it is. (even confuse it with response time)

    i'd appreciate hearing your opinion on the matter. I plan to use a PS3 with the 245T, and FPS will certainly be in the machine from time to time.

    Genuine 1:1 pixel mapping is also important to me, and if you could clarify the issue here i'd be much appreciated.

    cheers

    It does suffer from inverse ghosting.
    Most noticeable in gaming mode so I don't use that.
    Surprised it wasn't picked up. Also if you move your mouse cursor over a grey background you see noticeable ghosting.
