My Samsung 2253TQ was sent back for warranty and it came back to me after a few weeks, but its a Samsung 2233SWPlus as a replacement. I sold the LCD to my friend Tommy right after i tested it for a few hours(Don't worry, i will do a re-test on the 2233SWPlus when i get the chance). The reason of selling was the marketed 5ms instead of what i wanted, a 2ms lCD.

After searching and surveying the market for 22 inch LCDs with 2ms spec, i nearly gave up on searching due to the price for 22inch 2ms. As days passed by, i searched around the web for 23 inch and i came by the Acer H233H. Around most I.T oriented peoples, Acer is very much being *left out when they are shopping for LCDs or Laptops, some say the quality is not so good compare to others and some say its problematic. I come by this sayings often and it has given me an expression to avoid getting Acer, until whats left is Acer in my LCD list.

The Acer H233H is packed up nicely in a cool looking black box with great looking design (hey, I do stare at the boxes if they're looking good).

As you can see above, the few bright white words are the touch sensitive buttons. So its no longer the old button mechanism which could be damaged when we press around too often (they hardly spoil anyway).

BLACK LEVEL TEST:(standard 255LV test)
I think I have to point out is the Dynamic Contrast and Responds Rate, the stated specification on the Acer website shows its product running 40k Dynamic Contrast and 5ms Responds Rate, the model i have now sports a 80k Dynamic Contrast and 2ms Responds Rate. This brings a question on why it's showing different spec on the website and the actually market product.

GRID , UT3, Ghost busters: The Video Game , Call of Duty 2

NOTICE : The pictures displayed is not any print screen picture, it's a direct camera shot. Please do not judge solely on the pictures itself as the camera is not any DSLR camera which enables manual preset shutter speed and iso settings. The displayed pictures are to show you how exactly the display looks like.
 With the lack of proper testing hardwares, the result may be vary depending on each person's point of view and exeprience.  



 The Acer H233H displayed an impressive 254 score out of 255 ! This shows the H233H is capable to showing more objects in the dark. 



A racing game developed by the team who created the Operation : Flashpoint and Colin McRae Rally series. It features realistic graphics and vehicle physics, GRID is used for motion test for the LCD in order to determine whether its capable of giving good quality gaming. Racing game naturally do not need ultra-fast responds from LCD, a 5ms is more than enough for it.


As I was testing a 3 round drift match and an a Pro-Tune match and replaying it throughout the 6 total laps, the Acer H233H is capable of displaying objects fast enough without any lag.

After playing a few more rounds i'd say the Acer H233H is more than capable of playing driving games, no lag or any bad motion ghosting noticed.



The fourth installment of the Unreal Tournament series (excluding unreal championship and Unreal) , it's a fast paced First Person Shooter which requires good respond rate from the LCD in order to frag-without-delay. Most FPS veterans are capable of differentiate a 2ms and 5ms, although sometimes LCD with a 2ms rating will not guarantee to work as the exact 2ms rated.


The first thing I did was firing up a Deathmatch with 20 bots in skilled difficulty and with god mode enabled in order to test the game without getting fragged.
Running at the resolution of 1920x1080, with my pc generating a constant 40 Frames Per Sec (FPS) with Framerate Smoothing disabled, i find that the Acer H233H is still able to display static objects and dynamic objects fast enough if the player is not a crazy strafer HOWEVER, if the player is a Quake style mad strafer, I think the LCD will not be able to fully satisfy the needs unless it's a CRT we're talking about.
Unreal Tournament series and the Quake series are natural fast paced game compare to the usual conventional modern shooter.

The Acer H233H's UT3 respond is somewhere near my previously owned Samsung 2253LW but not on par of it. Nevertheless, it's still fast enough for keeping yourself on the top 3 in the 20 adapt skilled bot ladder.



A newly released Ghostbuster which continues as the sequel for the movie. This game served as our casual game test where it requires less strafing to prove whether the LCD is suitable for the casual gamers usage.


A slower third person shooting game which serves as our console simulation test on PC desktop LCD displays. After firing up GB (Ghostbusters) at the final boss stage, the Acer H233H displays the object flawlessly even if i'm mad strafing around busting the final boss's @ss.

This shows the Acer H233H is qualified for console games for sure. Hook up with a PS3 or Xbox360 to it's build in HDMI port and you're ready to go !



A well known second installment of the WWII first person shooter developed by InfinityWard. This game serves as our fast pace gaming test. It is no doubt a four year old game but still serves as our main FPS game with its oh-still-stunning visual. COD4 is not being tested as the game's bloom effect are too exposed compared to COD2.


As for the famous COD2, image quality is still superb and capable of displaying objects fast enough to sweep the "Nuts" machine gunners. However on certain dark places in COD2 like tunnels with concrete wall, the textures may look strange, it is mostly due to the game texture itself and the color might be grey-ish on surface bump-mapping.



Terminator Salvation 4 min 1080p trailer, Silent City 720p, I am Legend 1080p, Shrek The Third, 60sec Fraps recorded COD2 gameplay.

Three of the movie trailers turned out great responds great except the colors are abit on the grey-ish side due to quicktime mov files with default color profiles. However on Shrek The Third 720p and COD 2 1080 res .avi file shows more vibrant colour and movies turns out great with the Acer H233H.



After testing the usual tests when I get my hands on new LCD, these basic tests showed how well the Acer H233H performed in gaming , video and photographic usage.

The colour or image quality is very much near perfect, no back light bleed, no distortion, non static outputs on screen but the model which I got have small dead pixels that shows white during the screen shows black displays. Well, I guess I'm unlucky, nevertheless its unnoticeable during gaming or movie if the user sits at least a 50cm distance from the LCD. (no one will stick too close to any displays)

Acer is a well know brand for low priced product. By being low priced will place a question in our mind about it's product quality, well my friends think no further because the Acer H233H has proven to be a solid product on image quality and physical build. The Acer H233H is hanging on my wall with a wall mount, its solid, its fast and its beautiful ! With a price like RM650 for a 23.6inch, 1080p reso and HDMI capable 2ms LCD? What a bargain !
