Today Samsung launched two new UltraHD monitors with support for AMD's Freesync technology. AMD actually announced these monitors at their Future of Compute event last year, but there wasn't much information about them beyond the fact that they would be UHD panels and ship with Freesync support. As you may know, Freesync is AMD's alternative to NVIDIA's G-Sync technology to enable variable refresh rates on displays. We've talked about how this works and the implications it has, but the most significant benefit is that it can reduce stuttering and tearing when a game's frame rate isn't synchronized with the native maximum refresh rate of the display.

As far as these two displays go, they're two different sizes of UHD panels. However, while the 23.6" model is a PLS panel, the 28" model is a TN panel like the existing U28D590D which does not have Freesync. I've organized the most relevant specifications of both new displays below.

  U24E590D U28E590D
Panel Size 23.6" 28"
Panel Type PLS TN
Resolution 3840 x 2160
Refresh Rate 60Hz
Response Time (GtG) 4ms 1ms
Viewing Angle (H/V) 178° / 178° 170° / 160°
Inputs / Outputs 1 x HDMI 2.0
1 x HDMI 1.4
1 x DisplayPort 1.2
Number of colors 16.7 million 1.07 billion
Color Gamut 100% sRGB
Price $399 $599

Samsung's U28D590D was really the first affordable 60Hz UltraHD monitor, and aside from the addition of Freesync support the U28E590D is essentially unchanged. To me, the U24E590D is the more interesting display. At 23.6" it's a fairly high density UltraHD monitor, and it's a PLS panel which will definitely outperform the 28" display when it comes to viewing angles and color shift. Samsung advertises 16.7 million color support but it's not clear if that's achieved through temporal dithering or if the panel actually has an 8bit color depth for each color channel. At $399 it's also extremely affordable, and undercuts Dell's P2415Q which has been one of the most affordable non-TN 60Hz UltraHD dsplays up until this point.

The 28" U28E590D is available now for $599, and the smaller 23.6" U24E590D will be available for $399 on July 26th.

    sry i meant 4K :-)

    I'd like to see a 32" rather than the glut of 28" units we're getting, but I guess between the aspect ratios and desk space the latter makes more sense to most people.

    Shoot, I'm not even sure I really wanna go from 3x 24" back to two displays (one large 4K plus auxiliary), or if I have the desire to have three larger displays (which would probably require a new desk or a wall mount).

    40" would be really niche IMO, kinda small for a TV/couch distance display (I've lived with a 32" HDTV mind you, not saying 40" would be awful), but way massive for a desk.

    It's nice because the good one is the cheaper one. :)

    nobody want´s TN panels in 2015.. not even cheap gamers......

    It's good for a TN panel (I have the previous model), but if the 24" PLS version had been out six months ago I would have definitely gone for that instead.

    Will someone except Eizo limited and expensive editions produce 16:10 panel again?

    Go search for: 30" korean 2560x1600 monitor

    That is unless you are looking for another size, in which case I can't help you.

    Personally, I love my X-star DP2710LED, since it's doing 110Hz and 2560x1440 is tall enough for me. I find that once you go over 1200 pixel height with equally larger screen, 16:9, 16:10, 21:9, 3:2 doesn't matter anymore.

    That said, 1080p screens bug the crap out of me now.

    So the maximum refresh rate with free sync is 60hz, but what is the minimum refresh rate with freesync at 4K? freesync operates in a range
  • Nfarce - Sunday, July 5, 2015 - link

    Who would care about minimum Hz freesync specs? Nobody buys these types of monitors worrying about minimum FPS and matched monitor Hz!
