Best 32 HDTV to use as a pc monitor
I currently have a Samsung 24” 244T monitor which has a 60hz. Refresh rate and response of 8ms. I would like to upgrade to a 32” monitor since I watch a lot of films that are stored on my pc. The video reproduction on this monitor is not the best (some action sequences are rather ‘jittery’). I suppose this is due to the poor response time. I have been told I can use an HDTV as a pc monitor. My video card (SAPPHIRE HD5870 1GB GDDR5 PCIE Game Edition) has Dual DL-DVI-I+DP+HDMI, Triple Display Support. I would only consider upgrading if the HDTV will give me better video reproduction.
I am considering this Sony product:

I would ideally like a product that will give true 120hz using the HDMI input. I don't think the Sony does.
Does anyone here use an HDTV for this purpose and if so what are your recommendations?
Keep in mind that I have no interest in using it as a TV.
Thanks.

mm the faster the refresh the harder your computer will work so you ll end up less smooth
best refresh is 32 not to slow not too fast and computer will be happy
thats one reason why ps3 have 24 hertz instead of 60 hz.game would be almost unplayable at 60 hz full hd screen if it was at too high refresh rate.
1920x1080x32hz 1080p is the best setting (higher number arent always better espacially not when it come to refresh rate!)
only time indsutry put screen at high refresh rate is when they know their video will be on youtube.even then not too sure!
if your screen can do the number i wrote your problem isnt the screen then its the set-up of your os
kadaitcha.cx got good tip for xp and vista(window 7)
speedguide.net also have lot of good tip !
with those two site i never have smoothness problem
for kadaitcha.cx make sure you understand what hes writing if you dont understand ?do not apply the tip hes warning about!
last but not least if you got 4 gig of ram deactivate paging file! this should help a bunch!you might get error
in some game since some game are very badly writen but so gfar i had only one error i ignored it and restated my computer as usual.
I used to think this as well, I mean 60 hertz means it needs 60 frames rendered right? But that's not the way it works. The game performance is independent of the refresh rate of the monitor. This is because the GPU isn't involved with actually sending the frames out to the monitor. The ps3 at 60hz would just pump out 24 fps and look identical to a ps3 at 24hz doing 24 fps.
The GPU pumps out rendered frames to the display buffer on the card as fast as it can. Each cycle (1 hertz) the RAMDAC/TDMS on the card pushes whatever frame is in the buffer out to the monitor. The RAMDAC has nothing to do with the performance of the card, cards have been using the same 400Mhz RAMDAC (and now TDMS for digital signal but same principal) for the last 20+ years, all they do is push whatever is sitting in the display buffer out to the monitor.
If the monitor is running at 120hz, and the GPU is only doing 24 FPS, the RAMDAC just ends up pushing out the same frame in buffer 5 times before the video card gets the next frame rendered and pushed into the buffer. You would end up with 24 frames displayed per second, each for 1/120th of a second 5 times in a row (1/24th of a sec total per rendered frame). This is because the RAMDAC pushed the same frame from the buffer 5 times, *not* because the frame got rendered 5 times! If the refresh rate were 24Hz, the RAMDAC still pushes out whatever frame is sitting in the buffer each cycle (1 hertz) so you would get 24 frames displayed per second for 1/24th of a sec each frame.
Now what happens is at 24Hz, the GPU has no reason to render more than 24 frames per second because the RAMDAC will only be pushing 24 frames out to the monitor. So as a design decision the developers limit the max fps to 24 and bump the graphics up. They are capping the FPS at 24 because on a 24Hz display that's all that can be seen. At 120Hz, whether or not the 24 fps cap is in effect the game would only do about 24-28 fps just because they have the settings so high. The GPU isn't forced to render extra frames at higher Hz, the RAMDAC is just pushing out the buffer more times per second.
As an analogy I'd say it's like doing 24 mph in a 24 mph zone, and doing 24 mph in a 120 mph zone. Either way you're only doing 24 mph but it isn't the road that's making you drive so slow.
Also to OP, dunno about the TV, try to find a 120Hz with HDMI 1.4 I would think but I *think* most 120hz TV's are just 60hz input with interpolated filler screens (ie generated by the monitor). This gives the effect of a fluid, sharp picture but it's not actually getting 120hz of display data from the PC so wouldn't be able to do 3d or anything afaik. Might be all you need though to get the video playback you're looking for. Might be best to wait just a bit since a lot of new 120Hz screens were shown off at CES.
24 hertz screen refresh rate and ingame frame per second are 2 different beast altogether.
you can have 24 hertz refresh screen and get say 200 frame per second ingame
good luck trying to get 200 frame per second on a 120 htz screen.number could be diff .
this trick to lower screen refresh rate as been around for decade i was doing that on my pentium to up graphic quality for the same frame per second.
dont know if it can still be done back then i had an old nvidia intgrated card 8 mb or ram on the graphic card lol.
we had to have lower hz then 60 or image would have been awfull.but since screen techno is a lot different today !dont know if this trick can still be done.
on my 8800gt it can only be done at 1920x1080x24hz
my native resolution is 1650x1050x59hz minimum(margin of error)so 24 hz isnt avail but i think its an nvidia thing.
since they got the option at HD format.it basicly a trick to force people to buy HDscreen else nobody would buy new screen since most gamer got tin flat screen already.
I used to keep my refresh rate at 72Hz instead of the 85Hz it supported for that same reason, but then I learned it was all a misunderstanding of how things worked. The only part of the video card that deals with refresh rate is the RAMDAC and the RAMDAC isn't involved with rendering it just displays whatever the GPU has already got ready.
You'll get 200fps at 24Hz and 176 of those frames will never be shown, and you'll get 200fps at 120Hz and 80 of those frames will never be shown, the GPU *does not care* and renders all 200 of them in either case. The RAMDAC is the thing moving those frames out from the buffer to the monitor. When your fps is above your refresh rate most rendered frames are cleared from the buffer by a new rendered frame before the RAMDAC even gets a chance to display them.
ramdac?wasnt that on my pentium system!i could be wrong here but i dont believe my 8800gt got ramdac anymore since its a dvi plug now instead of the old analogue connector !
that why im trying to get info on this new technology to know if the old heartz dropping and rising quality trick still works
i dont know how it worked but at 60 hz game wasnt playable and if i tried to play at 32hz it was smooth .but then your right that was in the day of ramdac if not before since i only had 8 mb graphic integrated lol

this sheded some light to my idea.but im still in the dark lol!way more complicated for computer then it was back then lol
drbaltazar, stop giving such suggestions since you obviously don't know what 24 Hz refresh is meant for.
To OP, bad plan. Tv's have very high input lag and slow panels, they are only good for watching movies; in other usage they are inferior.
mm!i guess we all dont know what we talk about!120hz divided by 24 means yep you got it tv copy and paste 5 time that 24 hz
so for every frame card send tv will copy it 5 time to get it to 120 if you use 24 hz.
but then you already knew that!
Jesus. Really, google some information why it is implemented, and where it should be used. 24 Hz in gaming for example is totally unplayable.
true!32 hz is the minimum to prevent fliker and eye fatigue!i think i linked a website today about this in the hardware section it say it all!
You need atleast 120hrz
Sigh, are you even reading what I'm writing or don't you understand?
true!32 hz is the minimum to prevent fliker and eye fatigue!i think i linked a website today about this in the hardware section it say it all!
There is no flicker or eye fatigue with LCD's. Refresh rate is really a misnomer for LCD's, just a carry-over term and spec from CRT's. When you light up an LCD pixel it's in constant state of on until you turn it back off (black).
If you show a solid red screen on a CRT @ 60hz it's really flashing a red screen 60 times a second. @ 85Hz it's flashing the red screen 85 times a second. This is why your eye strain/dry out. An LCD works differently. If you light up the pixels red they stay red solidly. The only thing refresh rate determines for LCD is how often the controller will change the color of those pixels.
All video cards have a RAMDAC integrated. The 5870 has 2 RAMDAC's for example. HDMI/DVI use a TDMS to generate the clock but it's basically just a digital RAMDAC and part of the same circuitry.
