| | More on Samsung 151MP/171MP and LCD Monitors | | Question | Hank thanks for taking time for answering that Samsung montior question....LAst quesion about flatpanels.My friend and other people in the discussion board said,"NEVER PLAY GAMES ON A FLAT PANEL MONITOR"!!!! They also said since flatpanels use less Vf hz,then a games image will get that GHOSTly motion movement effect.Is this stuff true.On my dad's old laptop that does happen(its an old b/w 486).So is this true??
Thanks Hank | | Answer | From your previous question, I was under the impression that you have already witnessed the display quality of the monitor in question and were only curious to know if an Xbox would be compatible. Since you are searching for further information, here it is.
Here are the display specs for the two monitors:
SyncMaster 151MP
- Type: Active Matrix (TFT) LCD
- Viewable Area: 15"
- Pixel Pitch: 0.297mm
- Brightness: 250cd/m²
- Contrast Ratio: 330:1
- Horizontal Viewing Angle: 140º
- Vertical Viewing Angle: 120º
- Response Time: 25ms
SyncMaster 171MP
- Type: Active Matrix (TFT) LCD
- Viewable Area: 17"
- Pixel Pitch: 0.264mm
- Brightness: 250cd/m²
- Contrast Ratio: 400:1
- Horizontal Viewing Angle: 170º
- Vertical Viewing Angle: 170º
- Response Time: 25ms
Greater Contrast Ratio gives a wider range from black to white. For LCD monitors, this mainly refers to how accurately black displays. Monitors with low contrast ratio tend to display dark gray instead of black. Anything above 300:1 is already getting fairly accurate for true color displays. 400:1 is even better.
Horizontal and Vertical Viewing Angles are the angles where the monitor can still be viewed. 170 degrees means that the monitor can be viewed from 85 degrees in each direction. A 180 degree range would allow viewing the monitor even from its side; no flat screen (LCD or CRT) supports 180 degrees. So, 170º provides plenty of range.
Response Time determines how many distinct frames can be displayed per second. Faster response time results in less ghosting. 25 milliseconds response time allows 40 distinct frames per second. That's enough to prevent blurring even with quick onscreen movements. At least 60 FPS is ideal for HDTV viewing, but 40 FPS is not bad for flicker-free quick motion. Regular interlaced TV only displays 30 frames per second.
Don't confuse these frame rates with game frame rates. Monitor frame rate determines how many distinct images that can be displayed per second. The gaming frame rate determines how many frames the PC/console system (CPU, GPU, RAM, etc.) can generate per second in a game, without considering the performance of the monitor.
Vertical Refresh Rate is less significant than response time for current LCD monitors, since the display can refresh without actually correctly updating the position of a pixel. The response time determines how accurately the pixels can update.
Active Matrix LCD Monitors normally come in the range of 80 to 14 ms response time; that's 12 to 71 frames per second. Passive Matrix LCD Monitors usually are in the 300 to 150 ms range; that's an unfortunate 3 to 7 FPS. Most likely your dad's old laptop only has a passive matrix display; ghosting is very visible on such monitors. Even if the 486 laptop has an active matrix display, it could be using older technology in the 75 ms range (13 FPS).
Field reports of the Samsung SyncMaster 151MP and 171MP monitors show that no noticeable ghosting is visible even when playing 3D games and watching DVD movies. If you can see the monitor in action yourself with fast moving objects on screen, you should get a good idea of how gaming will perform on the monitor.
It's true that CRT monitors' display quality is still better than LCD, especially regarding response time and contrast ratio. However, the current best LCD monitors have acceptable response time and contrast ratio for gaming and movies.
On the flip side, LCD monitors do have some obvious advantages over CRT monitors. LCD monitors consume less power (electricity), are more portable, use less desk space (no desk space required if put on a wall), and look cooler. ;)
The Samsung SyncMaster 151MP and 171MP are both quite expensive. You should certainly be aware of that if cost is a concern.
