here's a monitor that is finally worthy of the price tag that it carries for being a high-end monitor it features a 100 Hertz refresh rate wide VA panel 1500 R curvature and thank the heavens above has much better backlighting and it's been standard white LEDs this is the Samsung C 34 CS 791 34 inch ultrawide monitor and let's take a look at why this thing is just so damn good welcome back garden for a long time we have been getting duped by the monitor industry with essentially what is called a white LED which are of course called blue LEDs with a yellow phosphor coating that makes a white light these are the LEDs are going to the majority of our monitors and even TV now the problem here is that when you have a pure white picture on your screen this so-called white light is actually sourcing the majority of the light from the blue spectrum with a white LED now you may be wondering why is this a problem well it's been from the fact that the cones in the center of our humanoid eyes are made up of predominantly red cones roughly 64% then green at around 32% then lastly comes blue at around 2 to 6% and furthermore right in the center of our eyes there are actually no blue cones at all so in other words seeing detail through blue light was never intended for human eyes which makes white LEDs arguably the worst back running to ever go into a monitor period the pre-existent C CFL or cold cathode fluorescent lamps we're much better in contrast pushing out a white light that was derived from firstly green then red then lastly blue so why is it that these white LEDs ever made their way into monitors in the first place well quite simply money lower production costs and easier marketing like oh my god 1,000% brighter and more energy-efficient etc is what made white LEDs a short sell for companies that opted to use them however the samsung c 34 has what is called quantum dot LEDs which are the ones inside this monitor and are very different in one regard they use nano crystals which when absorbing the blue light behind it spit out a pure green and pure red depending on the size of the crystals this now gives you a wide light that is made up of much more green red and hence will allow your eyes to see detail much better then a white LED otherwise could provide not only that your eyes will be less strained as a result and you will get a richer picture which is where I think people arguing this monitor is oversaturated maybe a little mistaken but rather their eyes may need to adjust to having been treated so poorly by inferior technology for years on end as oversaturation usually produces the thing called color bleeding and out of the box there is no color bleeding at all this rich or vibrant picture as I would rather call it is absolutely fantastic the light any gloss coating is one of the most effective I've seen yet providing a clearer picture yet still blocking out annoying reflections then there's a 100 Hertz refresh rate on this monitor which has support for AMD freesync technology ranging from 48 all the way to 100 Hertz on a 34 inch wide screen with a resolution of 1440 by 34 40 pixels on a VA panel moving on you have a low claimed response time of 4 milliseconds with overdrive on and it offers three different overdrive settings I opted to leave it on the default setting for faster and of course it's both relatively low input lag feeding out my other korean monitor here the monitor also comes calibrated out of the factory so i didn't have to turn the brightness down from 100 to 70 and that is about the sweet spot for me the backlight bleed on this monitor or lack of should i say what's the nominal on a pure black image i didn't notice anything out of the ordinary and the white background picture showed great uniformity the one thing you may want to take into account is that the closer you sit to this model the more likely you are to notice slight color or contrast shift i recommend sitting about 70 centimetres or more away from the monitor and it shouldn't be a problem though when looking in adobe premiere for example there is a unique thing where straight lines will appear slightly curved due to the nature of the monitor i personally adjusted to it very quickly and found it to be a great plus when using all the extra space for productivity looking over the physical aspect of the monitor it is height adjustable but not swivel it comes preassembled from the factory so you can just take it out plug it in and you are good to go it also comes included with a USB 3 cable power adapter DisplayPort and HDMI cable though I did have to manually changed my frame rate from sixty to a hundred Hertz in Windows to set this monitor to the hundred Hertz setting Samsung also claims as monitor is flicker free something that I can't verify with my limited gear the bezel is also extremely thin so there is still a black border that surrounds the image when turned on most likely helping alleviate any backlight bleed issues there's also a back plate to help mount this by a vase of mounting if you so wish to and the on-screen display is simply awesome to work with you have different pre-select modes to choose from picture and picture mode available color brightness and saturation settings and also Samsung's magic upscale settings available there is a game mode which does nothing to affect the monitors input lag and raises the gamma to levels that I'm personally uncomfortable with also I did have to change this from korean to english language since I got the CF 791 directly imported from Korea by a seller named dream seller lastly there is included stereo speakers which is great for someone who doesn't care about audio in my opinion so it is good for Skype calls and conferencing I found them to be lacking any warmth and bass and hence a pair of even $20.00 Logitech speakers would sound much better in my opinion so let's talk about price this thing comes in at 1,000 USD ship but that is shipped internationally from Korea to your doorstep on Amazon in the US you can get this thing a little bit cheaper and you also have that amazing Amazon support to go with it so in my opinion this is finally a monitor worthy of the title high-end gaming monitor boasting an exceptional VA panel fast 100 Hertz refresh rate great resolution and screen size and more importantly proper backlighting that won't to generate your vision over years of youth so there are more questions you guys may have like what about for instance OLEDs well after researching OLEDs apparently they have their own issues like screen burnin effects as opposed to this generation of QD LEDs which have no screens burn in effect on that note this generational technology of QD LEDs using this monitor are photoluminescence that is the green and red crystals are changed from the blue light behind it and as such can't instantly switch off to give you deeper blacks that OLED otherwise can which would be the only negative that I could take about this monitor so on that note I found the blacks to be still very good how this will be rectified I'm sure in the future when generation to QD LEDs hit the scene that is electroluminescent where the individual crystals will be able to be switched on by their own current so that is still a few years away from mass production so the last question what about the micro board version for $300 cheaper well the question you have to ask yourself is probably this is the much better back lighting worth it for you for me personally the answer is quite simple I would pay the premium for the Samsung and of course quality control from a company I've never heard of first one that has been around for years with proper customer support would be another factor worth considering especially at this price premium and who has that's about it for the review if you like this and be sure to hit that like button and let me know in the comment section below what do you think about the C 34 cf 791 from Samsung I personally love it I think it's great the companies are finally bringing in much better backlight technology into their monitors that are coupled with high refresh rates low input lags and also fast response time and you guys I'll catch you in another tech video very soon peace out for now bye
