Fantastic comparison of the monitors. Taken from
Budget Korean 27
Achieva: ShiMian
QH270-LITE
The ShiMian QH270-LITE is the cheapest option out of all the other brands and models. This model comes with the bare essentials without any added functionality. The stand used is the same as of all the other different Achieva models. General user feedback is that the stand is alright but does feels cheap and may be wobbly at times. There are mixed reviews over the unit, most people reported “perfect” panels in the sense that no faults can be easily seen or were detected. A few have detected dead and stuck pixels, usually one to two but nothing too major. Using this model as the universal price benchmark, it currently costs around ~$330 USD.
QH270-IPSB
The ShiMian QH270-IPSB is basically a QH270-LITE with tempered glass. The tempered glass does give a very sleek vibe to the monitor, almost similar to that of an Apple Cinema Display. It does have the same problem of heavy reflections should you not control the lighting within the room. The added tempered glass does in no one improve any kind of functionality except the pure aesthetic of the monitor. The main problem with the tempered glass is that not only do you risk the chance of having received a monitor with pixel faults, there is also the chance to receive a monitor with dust particles behind the tempered glass. This does not warrant you any form of compensation. Same thing as the QH270-LITE, most users are happy with their purchase with some mentioning about the dust as well as pixel faults but nothing too major. They are slightly more expensive at around ~$10 USD more than the QH270-LITE.
QH270-IPSBS
The ShiMian QH270-IPSBS is the model with internal speakers. People who used the speakers have expressed that the speaker quality is extremely poor, similar to that of your general laptop speakers. Due to the internal speakers, there is two additional buttons to adjust the volume of the speakers. They are more expensive than the QH270-LITE model by around ~$20 USD.
QH270-IPSMS
The ShiMian QH270-IPSMS is the multi input version of the series. It accepts 3 different kinds of input namely HDMI, DVI-D and D-Sub. This version also has internal speakers. There is a built-in scaler and the presence of an AD Board means that you can use this monitor to display 1080p content from your consoles and whatnots. It is mentioned by users though that because of the scaler, there will be input lag as compared to the other models. This model has an OSD. This model is relatively more expensive, around ~$150 USD more than the basic LITE version.
QH270-IPSTDP
The ShiMian QH270-IPSTDP is a TV monitor that has the functionalities of both a PC monitor as well as a television. It accepts multiple inputs namely component, 2 HDMI, D-SUB, DVI, DisplayPort, USB port and TV antenna. It also has a SPDIF port for your audio needs. There is the function to do picture-in-picture as well (displaying two different source at the same time). It is stated that it comes along with a remote controller as well. This model has an OSD. This is the most expensive model priced at around ~$450 USD more than the basic version.
QH270-IPSMDP
The ShiMian QH270-IPSMDP is almost the same as the QH270-IPSTDP with the only difference lying in the lack of TV antenna input and the functionalities of a TV. I am unable to find a price on eBay but I am estimating it to be just slightly less expensive than the QH270-IPSTDP.
Yamakasi: Catleap
Q270 SE
The Catleap Q270 SE has a circular based stand that apparently allows you to swivel 360 degrees. Apart from that, there is the chance of receiving a monitor that allows for overclocking to refresh rates of 120Hz. It accepts only Dual Link DVI input. Users generally have great feedback of the monitor with the exception of a few reporting with some pixel faults. These monitors cost slightly more than the Shimian Q270-LITE (~$20 USD).
Q270 Multi
The Catleap Q270 Multi is similar to that of the ShiMian QH270-IPSMS. It has 3 different input options namely HDMI, DVI and D-Sub. The internal speakers are rated at 2W per side as compared to the 5W per side of the ShiMian monitors with internal speakers. There is however, the additional option of audio out. There is also an OSD for the monitor. This monitor is priced at roughly ~$140 USD more than the basic Q270 SE model.
Crossover
27Q LED
The Crossover 27Q LED is similar to that of the ShiMian Q270-LITE. It also has a rectangular base stand but is said to be of better quality. The general consensus is that the overall build construct of the monitor and quality of the stand is the best among all the other brands. The general feedback from users is that the monitor is great and seemingly of higher quality than the rest. There are, however, still some people who came out saying that they received monitors with slight faults. Nevertheless, most users have a great experience with them. The model cost slightly more than the rest at roughly ~$50 USD more expensive than the ShiMian Q270-LITE.
27Q-P LED
The main difference between the Crossover 27Q-P and 27Q lies in the stand. The 27Q-P stand allows for the monitor to be rotated into a portrait position. Other than that all the other features and feedback is mostly the same as with the 27Q. This model does cost slightly more than the 27Q at roughly ~$20 USD more expensive.
27M LED
The Crossover 27M LED is the multi input version for the Crossover monitors. It accepts several different kinds of video input namely HDMI, 2 D-Sub, DVI, HDMI and component. There are the audio inputs of normal PC audio in as well as SPDIF. There is the presence of a pc audio out port as well. A USB(SVC) port is also available. The stand is similar to that of the 27Q-P. There are internal speakers rated at 7W per side for a total of 14W. These are relatively expensive and will set you back quite a bit. These are priced around ~$320 USD more than the ShiMian Q270-LITE and ~$270 USD more than the basic Crossover model.
PCBank
3View PB2700
The 3View PB2700 is similar to that of the ShiMian QH270-IPSBS in the sense that there is a pair of internal speakers. The monitor stand, however, is circular in shape. According to reviews online by Korean websites, it is said that the PB2700 has relatively better contrast ratio and response time as compared to the rest of the other brands. Users that purchased the PB2700 are generally happy with their buy and few have complained of any faults. They are priced at ~$15 USD more than the ShiMian QH270-LITE.
Davi
D279SV-VGQ2
Little are known of the Davi D279SV-VGQ2. There is a user that confirms that the monitor has an anti-glare coating to it, similar to the Dell Ultrasharp series. That makes it the only known Korean budget monitor that does not have a glossy panel. The rest of the functionality is the same as the ShiMian QH270-LITE but are priced slightly more expensive by ~$50 USD.
