100hz/120hz monitors / TVs - which cable? HDMI vs DVI-D/I (and single vs dual link)


I'm thinking of buying 120hz monitor and wondering about cables. Read some forums and mostly people recommend use DVI-D (dual) for 120hz monitors, what about HDMI 1.4 with HDMI to DVI-D to connect with GPU card while other side connects normal HDMI to monitor or TV.

Currently using 32" LG 3D TV as monitor because of giving away old pc with monitor to my sis. I use HDMI from monitor to HDMI to DVI-D for connecting with video card (as it only supports mini hdmi).

Some people keep saying that I don't get full 1080 with hdmi and with DVI-D I do. Also question regarding hertz and input lag with such cables, do I get some extra input lag with any of those cables and does both cables support 120hz ?

...was also theorycrafting , if I can overclock my 3D TV, which has (fake) 400 or 600hz to have (real) 100 or 120hz. Currently in fast phasing games, like CS:GO, where 100FPS/100+hz is a must, you can really feel the 60hz lag from pc. I do have selected PC input as PC and set for game mode, but still not a huge difference.

Forget overclocking the monitor. You really have more than enough refresh rate.

About the Fake HZ's you've been talking. Just take a normal TV with 1080p without 3D and having a 200hz label for example, the tv would run during games at 60hz which is a ripoff.

You're right that SOME HDMI cables aren't doing full 1080p but they have a very old interface. HDMI 1.4 does it easily 1080p@60Hz

Well to make use of your speakers and usb ports and all that blablabla whatever exists on a tv nowadays you need a hdmi cable or Displayport. Some HDMI cable's have a lower bandwidth speed than the expensive one's. The refresh rate makes also a part of a higher bandwidth btw. I don't think if a HDMI cable would support 1080p @ 120hz. If there would be one it should be expensive.

Just go for a Dual link DVI cable or if you already have a DisplayPort cable/port at tv.

don't think my card supports displayport (gtx 480), it's like ATI's GPU regular port I guess. Trying to find good 120hz with/without 3d monitor 24" or even better 27" one,but ones I found use display port, which my gpu doesnt support.

BENQ XL2420T is a 3D monitor. I found it really hard to find monitors without 3D having a refresh rate of 120hz. Seems like the 3D monitors are only capable. Also the monitor I've just linked includes a dual link dvi cable and has native 120hz support.

I have quick question regarding 60hz monitor vs 60hz TV at 1080p (or 1080i for TV via hdmi?).

How can my current rig with previous monitor giving me smooth gameplay in FPS (CS:GO) above 100FPS while my TV isn't smooth and actually feels like half of monitors FPS, eventho GPU stats and CS:GO net_graph says that fps and rest of parameters are identical?

My TV: LG 32LV450U http://www.lg.com/uk/tvs/lg-32LV450U-led-tv
My previous monitor: LG W2253TQ http://www.lg.com/us/monitors/lg-W2253TQ-PF-lcd-monitor

Make sure that your GPU setting and TV setting is 1080p and not 1080i

1080i = 1080 INTERLACED, which means that it will first refresh horizontally, then vertically, so the refresh is half (30hz)
108p = 1080 PROGRESSIVE which means that it refreshes all of them at the same time.

it does show as 1080p.

I also set TV input as PC (which reduce a little mouse lag), also change AV to game.

any suggestion?

Could it be wrong with mouse input due to larger scale display for PC?

Overclicking USB port would reduce mouse input lag on TV?

I was under the impression that one of the the reasons people tend to not hook computers up to televisions is response time. I could be incorrect in that statement, but something is largely different between monitors and televisions in how they handle input (Namely input from objects like a mouse). When looking up your TV I found no listing of the response time, but I did find quite a few other televisions that boasted a 2ms response time, more than low enough for computer gaming.

With my above statement I am quite sure that overclocking your usb port will not improve the lag. Also larger scale display doesn't mean more pixels, it simply means larger pixels. Your computer isn't having to do more work to output to the television, you television is unable to cope with the stress of displaying your computer.

To remove completely input lag on your TV, you have just to turn off picture improvements in TV's menu, just turn all off, then turn on 1 by 1 to check what makes input lag

ignore what anyone says about hdmi cables. Make sure its the latest specification (1.4 i think?) and as short as possible (don't use 12 feet cable when 3 will do). It is a DIGITAL signal. This means it is sending 0's and 1's and only 0's and 1's. You cant have a more zero-y zero are a more oney-one. If the signal was not transferring appropriately, you would see a black screen / no audio. It would not have a negative impact on the frame rate or video quality. Anyone who says otherwise is probably the one selling you the cable for $100, or the one who bought a $100 piece of wire and doesn't want to face the fact that they have been duped.

I use game AV mode, which does reduce abit input lag and there isn't much I can change, when game mode is enabled.

This. Cables have little to nothing to do with quality when dealing with digital. If you see a picture it's doing it's job. The problem you're dealing with is input lag. The gap between your television receiving a signal, processing the signal and displaying the signal isn't an issue for watching tv. But when you're doing something (like moving a cursor) that needs to happen in almost real time 20+ ms of delay can make the process near impossible. Especially in gaming where the ability to react quickly is important. If you've ever tried to calibrate rock band or guitar hero you'll know how evil input lag is and most televisions don't advertise input lag.

If you're picking a tv with the hope of using it occasionally or full time as a monitor make sure you do some reading before you pick one. Otherwise always go with a monitor because you'll never find one with input lag even close to what you find on a tv
