Date Issued: 15th May 2015

Choosing a monitor is not an easy decision to make, and not just because of the large number of variations in resolution, refresh rates, sizes and connectivity options. There are also varying panel technologies used to form each display that need to be considered. These panel technologies can be grouped into three broad categories which cover the vast majority of monitors sold in the consumer market.

G-SYNC works in a surprisingly simple way - it calculates how long the present frame takes to compute and then, crucially, varies the refresh rate of the monitor to match. It works between a minimum of 33.3ms (30fps) and the maximum supported refresh of the display. The key takeaway here is that the graphics card and monitor are both synced up to one another - the monitor doesn't have the limitations imposed by a rigid, fixed-rate scanning routine.

Now shipping with all but the cheapest complete PCs are LCD monitors. Advances in display manufacturing and associated cost reductions with economies of scale have brought LCD monitors into the mainstream, shipping with budget systems that start at just £400. LCD monitors come in all shapes and sizes, have differing resolutions and inputs. The purpose of this TekSpek is to provide a basic understanding of how LCDs work, delineate their desirable features, and to offer basic buying advice.

As you’ll all likely know by now, DVI is the current standard for connection of a PC or other display generator to a digital display output. You’ll recognise the multi-pin connector and know that almost all modern LCD displays have the corresponding input connector, for feeding from your PC. But do you know how DVI works? This TekSpek seeks to teach you how.

Date Issued: 14th Jun 2008

Whether the broadcasters are going HD or not, TV sets and projectors are arriving thick and fast which claim to support higher resolutions than regular telly. But HDTV is far from just one standard – it incorporates a couple of different resolutions, two different scanning modes, and a number of different frame rates. In this article, we present a guide to what all the terms actually mean.

There’s a lot more to High Definition than just having the ability to run your screen at the right resolution. With more than one type of connection available, and the thorny subject of signal encryption to contend with, just because your monitor and graphics are capable of 1,920 x 1,080 or better does not necessarily mean they will be able to display HDTV in all its glory.

25" Dell U2518D 2K IPS Monitor, 2560x1440 (WQHD), 5ms, 1000:1, 350cd/m², USB Hub, HDMI/mDP/DP Out/DP In is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Bright and sharp 1920x1080 is great at this size, x1200 better, but 2560x 1440 is superb. Colours are great with the IPS screen. A good buy.
Date published: 2019-03-29
Rated 5 out of 5 by from My first 1440p monitor It is expensive but well worth it. I use it both for creativity and gaming. The out of the box sRGB colour accuracy is perfect with a colour accuracy report from Dell inside the box. At first the image was dull looking like my old monitor in sRGB mode but then after a couple days I noticed the colours come out. I have this powered by my GTX 970 and I found that I am getting better frame rates than my old 1080p monitor as I don't need to use aggressive anti-aliasing now at 1440p. FXAA is plenty on this. The 'Dell HDR' feature was not a feature why I chose this monitor. Bear in mind this isn't actual HDR but Dell's version of being able to accept a HDR signal and process it to display on this panel. Firstly I found that this monitor is able to output 10-bit colour in the NVIDIA control panel via mini-DP for some reason. I don't know if it actually is 10-bit. Also there is a 12-bit option via HDMI but this is just Windows thinking it's a HDR panel as it will go black if you try to select this. More games are supporting HDR and it's very interesting on this monitor. I updated the firmware on this monitor to M2T103 which Dell says "optimises HDR colour". Games in HDR mode on this are a mixed bag. Shadow Warrior 2 seems to have a duller look whereas Far Cry 5 and Destiny 2 look stunning. Brightness can be a issue as in Far Cry 5 as you cannot control brightness. Furthermore for some reason the monitor displays a HDR+ symbol in the monitor navigation OSD when playing Far Cry 5 and only on this title I have come across. On other games you don't see the HDR+ symbol and you can control monitor brightness in HDR mode, but for some titles you cannot control peak white brightness via the game like Destiny 2 and whites can seem overly bright in some areas of the game, whereas you can control peak levels in Assassin's Creed Origins. White peak brightness control seems to be the games fault not the monitor. Overall I find the Dell HDR feature to be good. I was amazed at Far Cry 5 and Destiny 2 in this mode. The photos of Destiny 2 are a representation, it looks far better in person. Other things I love are the height, pivot and swivel adjust. Scaling with windows is getting better. I have mine scaled at 125% and it's just perfect. Photoshop recently got updated with better scaling support and it's so good. Some applications you need to override high dpi scaling behaviour in the compatibility for some blurry looking programs. Remember to head over to the NVIDIA control panel and make sure colour output dynamic range is set to full. I don't know AMD equivalent. Also the lowest brightness setting on the monitor can seem a little too bright at night with the whites. You can change the monitor colour temp values for comfortable night viewing. Overall I am very happy with this monitor, beautifully colour accurate, borderless display, crisp 1440p and vibrant gaming.
