What is the Samsung SE790C?
SpecificationThe SE790C uses a VA panel with a screen size of 34-inches at an ultra-wide (WQHD) 21:9 aspect ratio with a 3440 x 1440 resolution. It employs LED’s mounted at the edges to illuminate the LCD pixels and has a claimed contrast ratio of 3,000:1, a peak luminance of 300cd/m2 and a pixel response time of 4 milliseconds (grey to grey).
Design & Connections
Menus & Setup
sRGBWe can see from the two charts on the left, under the Pre-Calibration, heading that the SE790C was impressively accurate out of the box. The panel is more than capable of reaching the necessary colour saturations of the primaries (Red/Green/Blue) - in fact it’s a tad over-saturated in both red and green- but we can also see that various important colour points on the ‘colour checker’ graph on the left are being met, or at least close to it. The average Colour Checker error is 1.92, where below 3.0 is considered as being indistinguishable from perfectly accurate to the human eye. The RGB Balance Graph emphasises the out of box fidelity of the Samsung; in an ideal world the red, green and blue lines would all be tracking together on the zero point of the y axis but, as it is, there’s relatively too much blue and green energy in the greyscale with red dipping under. Still, overall greyscale errors are averaging just 1.58 so, again, any tint should be imperceptible.
Adobe RGBAs one would expect, greyscale accuracy in the Adode RGB colour space was similarly accurate to that in sRGB but the panel was not able to produce colours as wide as necessary for this colour space. To be fair, as the Colour Checker chart demonstrates, it didn’t make a bad fist of things but green could reach nowhere near full saturation levels and as a result, cyan – which is 50% comprised of green – was unable to either. More alarmingly green was a long way off being on-hue which would impact on those who need Adobe RGB accuracy.

Viewing Angles & Screen Uniformity
Bright screen uniformity of the Samsung SE790C was also very good, but probably the weakest point of this monitor was in its patchy dark-screen performance. Several instances of light bleed were noticeable around the edges of the screen when looking at very dark images and it’s not something we’d expect of a monitor costing nearly £800. This particular sample also had a column of dead pixels running around three-quarters of the way down the screen, too, which had this have been something we’d bought, we would have been looking to exchange.
Overall Picture Quality

·Standby – 0.3 watts
- Excellent colour accuracy, even without calibration
- Strong black levels and contrast performance
- Low input lag
- Good pixel response and clarity
- USB charging
- The curve works at close quarters
- Some dead pixels
- Edge-bleeding on dark screens
- It's not cheap
Samsung S34E790C Curved Monitor Review
Should I buy the Samsung SE790C?If you’re looking for a great all-round monitor with superb colour accuracy and impressive picture contrast, the Samsung SE790C makes for an excellent choice. The enveloping, curved 21:9 ratio screen also serves to draw you in to whatever pursuit you’re undertaking, be it games, movies or boring old work. Connectivity is good with two HDMI and one Display Port around the back and the SE790C also houses four USB ports – two of which can be used for ultra-fast charging of connected devices. The Samsung is a very good choice for gamers, too, with very low input latency and fast pixel response making for a silky-smooth experience. There were a couple of uniformity issues with a column of dead pixels and some edge-bleeding from the backlight but they rarely got in the way. That said, if it were our money, we would be looking to exchange on the dead pixel front but, provided all was well with the replacement, the Samsung SE790C would be a monitor we would be more than happy to use day to day. At £799, or thereabouts, it’s certainly not a budget option but quality like this costs. Recommended.
