Samsung CF791 34in Quantum Dot Curved Monitor

The CF791 has a 34in diagonal and 21:9 aspect, so it's a pretty hefty package.

 

Inside that hefty box can be found a VESA mounting bracket, HDMI, DisplayPort and USB upstream cables. There's also a certificate of factory calibration.

 

The 1500R curvature is pretty curvy. Most curved screens use 2000R or above. It's also very elegantly styled, with a thin support arm and demure base.

The screen's height can be adjusted by 100mm, and you can tilt it up to 14 degrees forward or 34 degrees backward, depending on where it is on the height adjustment. But you can't swivel the screen and (as with most curved panels) rotating is out too, for fairly obvious reasons. With hardly any bezel, apart from along the bottom, there's little to distract you from what is onscreen.

The main video ports sit behind a plastic panel, which is fairly easy to remove and replace so doesn't hinder things too much. Samsung claims its port choice is for games console usage, but either way you get a useful set of two HDMI and a single DisplayPort. So whilst there's no legacy DVI or analog connectivity, you can at least plug in three inputs.

The USB downstream ports aren't underneath the cover, and neither is the headphone jack, although having them round the back still isn't the most convenient location. There are also only two USB 3.0 ports, which we could understand if there was a built-in webcam taking one of the downstream connections, but there isn't. So two ports is a little miserly.

The on-screen display (OSD) menu is accessed via a joystick on the back of the screen, with no extra buttons to contend with. So there's no fiddling around trying to make sure you've pressed the right button. Reaching around for the joystick isn't that hard, either, unless you have really short fingers.

  1. quantum dots have sweet fuck all to do with the amount of colours shown as that info-graphic implies, that’s just the bit depth of the colour space the monitor supports, eizo, nec and other pro monitors have supported 10 bit colour for years.

    And wtf is the point in a 125% srgb rating? if you’re in an srgb colourspace, you’re only going to see srgb, how much of argb does this cover?

    Why is a monitor with all the professional/high end features being sold on a mis-advertised display technology? if they said, we’ve got a 85% ARGB, UW 1440p, 10 bit, 34″, bezel free, 100hz, g-sync, curved screen monitor I would be SOLD.

    Also, why do the specs on page 1 say g-sync, but the rest of the article says freesync? does it do both? does it do neither? who knows.

  2. I’d like to see manufacturers investing on a tad smaller 29″ ultrawide monitors with good features such as 100hz and HDR, but they only do this with the higher-end 34-35″ which are way out of my range speaking money and desk space… though that new one from AOC, 35″ for only only $800 isnt all that far away from what I’m confortable spending on a monitor, yet still too big for my desk… (Nope, I can’t buy a larger desk it wouldn’t fit my room). If AOC made a 29″ variant of the AG352UCG with flat panel 1080p while keeping 100hz or at least 90hz I imagine it would reatail for about $550 and that’s very acceptable for me.

  3. This would not be a first look at Quantum Dot tech Sharp has had it in their TV’s for a few years now. Maybe a first for computer monitors I’m not totally sure but I am about Sharp having this for at least five years now.

  4. Apparently, the only thing quantum-dot about it is that it has the back-light used for those displays but not the pixels.

  6. Managing director of Google!, is explaining to users to start off “Work at home” method, that People have been doing for about one year now. These days alone, I generated close to $36,000 until now with no more than my home computer as well as some spare time, despite that i have a fulltime 9 to 5 job. Even everyone not used to this, can make $89/per h easily and the earnings can go even higher over time… This is how i started

  7. Typo. Sorry about that. Thanks for pointing it out. Now changed.

  8. I think you are thinking about quattron TV’s. I have one and it uses 4 sub pixels. Red, blue, green and yellow. It’s not the same as Quantum Dot. But still looks amazing.

  9. You have me scratching my head. Since when is 4ms a bad response time? 4ms is an above average near superb, yet not a 1ms. The difference between a 4 and a 1 is 3ms (yeah, I know math lol) so is wayy faster than all but the very best gamers reflexes. Yes. Its a better measurment but realistically only one percent of folks will be able to tell the difference between a 1 and a 4.
    Just wondering” Why is a 4 not as good as i think it is”?

  10. I’m a bit confused why it is advertised at a 3000:1 contrast ratio but the max during these tests was 1250:1 can anyone clear this up for me? Thanks

  11. No, freesync test, no input lag test. With out these display tests are useless.

  12. This monitor is much higher than 1250 contrast something is wrong with their testing method.
