Dell’s UltraSharp U2720Q was our main pick in an older version of this guide; compared with the S2722QC, it has a higher, 90 W USB-C charging rate and a slimmer border around the screen. If you can find it for around the same price as the S2722QC, it’s still worth considering. But as of this writing, it’s either out of stock or considerably more expensive than the S2722QC, and it’s just not worth paying extra for.

The biggest failing of the ViewSonic VG2756-4K is its mediocre 949:1 contrast ratio, which is okay in a budget monitor but harder to swallow in a model that usually costs around $500. Its performance in our color-accuracy tests was also mediocre. It has many of the other features we look for in a good 4K monitor, including a USB-C port, a USB hub (along with an Ethernet port), a flexible stand, and a three-year warranty. But its image quality is a step down from that of the Dell S2722QC and the HP Z27k G3.

We also didn’t test the 27-inch LG UltraFine 5K Display, an even-higher-resolution screen for Macs with Thunderbolt 3. It’s very expensive, and getting it to work with Windows is either complicated or impossible depending on the PC you’re using.

The Acer B326HK and the BenQ PD3200U are sometimes cheaper than the 32-inch monitors we considered, but when we tested them in 2017 and 2019, respectively, we were disappointed by their mediocre contrast and color accuracy. They’re also missing newer features that we consider essential in a high-end monitor, such as a USB-C port.

DS Media Players: Display HD and ultra-high definition (UHD) content though LG’s powerful, cost-effective and reliable Digital Signage (DS) players, which support different a wide range of video and audio formats.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) dominates the world flat panel display market now. Thanks for its low cost, sharp colors, acceptable view angles, low power consumption, manufacturing friendly design, slim physical structure etc., it has driven CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) out of market, squeezed LED (Light Emitting Diode) displays only to large size display area. TFT LCD displays find wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, handheld devices, video game systems, projectors, consumer electronic products, advertisement etc. For more information about TFT displays, please visit our knowledge base.

There a lot of considerations for how to choose a most suitable TFT LCD display module for your application. Please find the check list below to see if you can find a right fit.

Resolution will decide the clearance. Nobody likes to see a display showing pixel clearly. That is the reason for better resolution, going from QVGA, VGA to HD, FHD, 4K, 8K. But higher resolution means higher cost, power consumption, memory size, data transfer speed etc. Orient Display offers low resolution of 128×128 to HD, FHD, we are working on providing 4K for our customers. For full list of resolution available, please see Introduction: LCD Resolution

TFT screen brightness selection is very important. You don’t want to be frustrated by LCD image washout under bright light or you drain the battery too fast by selecting a super brightness LCD but will be used indoor only. There are general guidance listed in the table below.

Orient Display offers standard brightness, medium brightness , high brightness, and high end sunlight readable IPS TFT LCD display products for our customers to choose from.

If the budget is tight, TN type TFT LCD can be chosen but there is viewing angle selection of either 6 o’clock or 12 o’clock. Gray scale inversion needs to be taken of carefully. If a high-end product is designed, you can pay premium to select IPS TFT LCD which doesn’t have the viewing angle issue.

It is similar to viewing angle selection, TN type TFT LCD has lower contrast but lower cost, while IPS TFT LCD has much high contrast but normally with higher cost. Orient Display provides both selections.

Normal TFT LCD displays provide wide enoughtemperature range for most of the applications. -20 to 70oC. But there are some (always) outdoor applications like -30 to 80oC or even wider, special liquid crystal fluid has to be used. Heater is needed for operating temperature requirement of -40oC. Normally, storage temperature is not an issue, many of Orient Display standard TFT display can handle -40 to 85oC, if you have any questions, feel free to contact our engineers for details.

Power consideration can be critical in some hand-held devices. For a TFT LCD display module, backlight normally consumes more power than other part of the display. Dimming or totally shutdown backlight technology has to be used when not in use. For some extreme power sensitive application, sleep mode or even using memory on controller consideration has to be in design. Feel free to contact our engineers for details.

High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.

This monitor was bought to be put in the headrest of a 2006 gmc sierra crew cab sle. The fit was tight but it works like a champ. I think i should have bought on a little smaller maybe 5 inches instead of 7 but this one worked fine. The only issue i see is one that i think most tft monitors will have and that is that the viewing angle is not that great. Because its on the back of the seat if the seat is reclined back too far the viewing angle for an adult in the back would be around 5-10 degress looking down on the monitor. that angle causes some of the color to wash out while viewing. Like i said I don"t know if there is anyway around that with tft other than adjusting the headrest height or the angle of the seat. But i would recommend this for someone wanting to install headrest monitors at a low price. I"m actually buying another one to put in the passenger seat and decided to write this review during my purchase. also keep in mind that once you install the monitor, even though it is removable its not that easy to remove. The monitor does have release buttons to remove from the headrest shroud but there is a cable that you will have to run through your seat for power and video that makes it not easily removable. it can be done but depending on your install if its like mine i ran the wire inside the seat cover so i would have to unsnap the seat covering to reconnect once disconnected and that isn"t something you want to do on regular basis. the monitor does have a power button so you can turn it off separately with the car on.

Over time, the image quality on your computer monitor can start to look a little lackluster or even too bright. Before you consider upgrading your entire system or getting a new monitor, there might be a much simpler, quicker, and economical solution — calibrate your monitor.

You could take your monitor to a professional to have it done, but doing it yourself is relatively quick and hassle-free and will greatly improve image quality. Manufacturers keep pumping out displays with new technologies like 4K UHD resolution, high dynamic range (HDR), and curved monitors, providing a veritable feast for the eyes — but only if they are properly calibrated.
